108.01 108-1 SECTION 108 PROSECUTION AND PROGRESS
108.01 Subletting of Contract. The Contractor shall not sublet, sell, transfer, assign, or
dispose of the Contract or Contracts, or any portion thereof without written permission of the Engineer. Before beginning any work by the subcontractor, the Contractor shall request permission from the Engineer by submitting a completed Sublet Permit Application, CDOT Form. 205, via the B2GNow software system. The subcontracted work shall not begin until the Contra ctor has received the Engineer’s written permission. The Contractor shall make all project -related written subcontracts, agreements, and purchase orders available to the Engineer for viewing, upon request, and at a location convenient to the Engineer. The Contractor will be permitted to sublet a portion of the Contract. However, the Contractor’s organization shall perform work amounting to 30 percent or more of the total original contract amount. Any items designated in the Contract as “specialty items” may be performed by subcontract. The cost of “specialty items” so performed by subcontract may be deducted from the total original contract amount before computing the amount of work required to be performed by the Contractor’s own organization. The original contract amount includes the cost of material and manufactured products that are to be purchased or produced by the Contractor and the actual agreement amounts between the Contractor and a subcontractor. The proportional value of a subcontracted partial contract item will be verified by the Engineer. When a firm both sells material to a prime contractor and performs the work of incorporating the materials into the project, these two phases shall be considered in combination and as constituting a single subcontract. The calculation of the percentage of subcontracted work shall be based on subcontract unit prices. Subcontracts or transfer of Contract shall not release the Contractor of liability under the Contract and Bond. Failure to comply with all contractual obligations may lead to the suspension, debarment, or both of the subcontractor, and if necessary, the Contractor as stipulated in the “Rules”. All firms that the contractor will be subletting a portion of the contract shall have an account created in the B2GNow software system. If the firm does not have an account created approval of the form 205 may be withheld.
108.02 Notice to Proceed . The Contractor shall not commence work before the issuance of a
Notice to Proceed. The “Notice to Proceed” will stipulate the date that contract time commences. When the Contractor proceeds with work before that date, contract time will commence on the date work actually begins. The Contractor shall commence work under the Contract on or before the 15th day following Contract execution or the 30th day following the date of award, whichever comes later , or per the selected start date allowed in the special provisions.
108.03 Project Schedule .
a.Definitions. Activity (Task). A portion of the project that requires time or resources to complete. An activity has a description, start date, finish date, duration, and one or more logic ties. A critical activity is an activity on the critical path. 108.03 108-2 Activity ID. A unique, alphanumeric, identification code assigned to an activity that remains constant throughout the project. Baseline Schedule. The original, approved project schedule before the project begins with no progress. Calendar. Defined work periods and no work periods that determine when project activities can occur. Multiple calendars may be used. Constraint. A restriction imposed in a schedule, which fixes a value that would otherwise be calculated within the schedule. Examples of values that can be fixed by a constraint include start date, end date, and completion date. Critical Path Method (CPM) Scheduling. CPM Scheduling is a logic- based planning technique using activity durations and relationships between activities to calculate a schedule determining the minimum total project duration and the interdependencies of all activities. Critical Path. The longest logical path through the CPM network driven by calendars, constraints, and activity logic. It consists of activities that determine the shortest time for project completion and the sequence of activities such that a delay to any of the activi ties on the critical path will prolong contractual project milestones, such as project completion. Data Date. The starting point from which to schedule all remaining work. It can also be considered the cut -off date wherein all work before this date has actual starts, actual finishes, or both. Duration. The estimated amount of time needed to complete an activity. Free Float (Free Slack). The amount of time an activity can be delayed without delaying the Early Start or Early Finish of its successor activity or activities. Gantt Chart. A time -scaled graphical display of the project’s schedule. Lag. A time -value assigned to a relationship. Logic. Relationships between activities defining the sequence of work (See also predecessor activity and successor activity). Milestone. An activity, with zero duration used to represent an event. Near Critical Activity. An activity with a total float of five days or fewer, or as defined by the Engineer. Open -Ended Activity. An activity that does not have a predecessor activity and a successor activity, or only has a start -to-start as a predecessor or finish -to-finish as a successor. Planned Completion Date. The date that the schedule shows work is planned to be completed. Predecessor Activity. An activity that is defined by schedule logic to precede another activity. Relationship. The interdependence between activities. Successor Activity. An activity that is defined by schedule logic to follow another activity. Time -Scaled Logic Diagram. Gantt chart that illustrates logic links depicting both schedule logic and the time that activities are performed. 108.03 108-3 Total Float (Total Slack). The amount of time between the earliest date an activity can start and the latest date when an activity must start, or the earliest date an activity can finish and latest date when an activity can finish before the activity causes a delay to the time specified in the Commencement and Completion of Work special provision.
b.Project Schedule - General The Contractor shall use either Microsoft Project or Primavera Scheduling software to develop and manage a CPM Project Schedule to plan, schedule, and report the progress of the work. Before , or at the Pre -construction Conference, the Contractor shall notify the Engineer in writing, the scheduling software the Contractor shall use to manage the project. The Contractor’s selection and use of particular scheduling software cannot be changed after the first schedule submittal. If the Contractor selects Primavera, the Contractor shall calculate the schedule using the Retained Logic scheduling option. The Contractor shall submit schedules for approval by the Engineer. The Contractor’s schedule shall be an accurate plan to complete the work so that the Department can use the schedule to evaluate progress, schedule CDOT resources, inform the project stakeholders, and evaluate the effect of changes to the schedule. A schedule review meeting shall be held to discuss each schedule submittal. The Contractor shall submit a monthly update as either a Project Schedule Update or Revised Schedule as determined by the Engineer. When the project has a maintenance or landscape establishment period, the Engineer may waive the monthly update requirement during that period. The Contractor shall submit a final update that shows all work through the final acceptance date. The Engineer will not issue a monthly progress payment if the Engineer has not received an update. The Engineer may not make monthly progress payments for the months following the update submission until the Engineer either approves or approves- as-noted the Project Schedule Update or Revised Schedule. The Contractor shall use activity descriptions that ensure the work is easily identifiable. Activity description shall start with an action verb when practicable to clearly communicate what is being performed. The Contractor shall show the no -workdays in t he schedule calendars. The contract completion date shall be included as an activity. The Contractor shall use durations for individual construction activities that do not exceed 15 days of work unless approved by the Engineer. The Contractor may group a series of activities with an aggregate duration of five workdays or less into a single activity. Non - construction activities may have durations exceeding 15 days of work, as approved by the Engineer. The Contractor may include summary bars in the schedule as long as the detailed activities to complete the work are displayed. The Contractor shall not use the following unless approved by the Engineer:
1.Negative lags.
2.Lags in excess of 10 workdays .
3.Start-to-finish relationships.
4.Open -ended activities.
5.Constraints. 108.03 108-4 The Project Schedule shall show all activities required by all parties to complete the work. The Contractor, its subcontractors, suppliers, and engineers, at any tier, shall perform the work according to the approved Project Schedule. Float within the Baseline Schedule or any other Project Schedule is not for the exclusive use or benefit of either party but is a project resource available to both parties as needed until it is depleted. The Engineer’s review of the schedule will not exceed 10 days. The Engineer will provide the Contractor with one of the following responses within 10 days after receipt of the Project Schedule :
1.Approved, no exceptions taken.
2.Approved- as-Noted; or
3.Revise and Resubmit within 10 days. Approval of the Project Schedule shall not relieve the Contractor of any contract requirement including the requirement to complete all work within the Contract Time. Contractual requirements shall not change by submission or approval of a schedule, unless specifically amended by a Change Order.
c.Schedule Submittals. The Contractor shall include a time- scaled logic diagram with all schedule submittals that:
1.Is plotted on a horizontal timescale per the project calendar.

For all required schedule submittals, the Contractor shall submit two USB flash drives or other media as directed by the Engineer with electronic copies of the schedule submittals. Electronic copies of the CPM schedules shall be submitted both in the nativ e file format and in Portable Document Format (PDF). Each schedule submittal shall be appropriately labeled as a Preliminary Schedule, Baseline Schedule, Project Schedule Update, or Revised Schedule. The title bar shall include the CDOT project number, subaccount, project name, Contractor name, and schedule data date. If an originally submitted schedule is revised during review, the title bar shall also include a revision number (REV1, REV2, etc.) revision date, and submission date.
d.Preliminary Schedule. Within 14 days of Award of the Contract, the Contractor may submit a Preliminary Schedule showing all planned activities from the Notice to Proceed through the first 60 days of the project. If the Contractor elects not to submit a Preliminary Schedule, then the Contractor shall submit a complete Baseline Schedule within 14 days of award of the Contract, which will be subject to all requirements of a Baseline submittal. The Preliminary Schedule shall not show any progress and it will be approved by the Engineer before work can commence. The Preliminary Schedule shall be used as the basis for the Baseline Schedule.
e.Baseline Schedule. If the Contractor elects to submit a Preliminary Schedule, within 45 days of the award of Contract, the Contractor shall submit a Baseline Schedule that includes all work activities completed within Contract Time. The Contractor shall not show progress in the Baseline Schedule. Further partial payments will not be made beyond 60 days after the start of Contract Time unless the Baseline Schedule is approved. When approved, the Baseline Schedule shall become the Project Schedule. The Contra ctor shall use all information known by the Contractor at the time of bid submittal to develop the Baseline Schedule. If the Contractor elects to submit a Baseline Schedule in lieu of a Preliminary Schedule, the Baseline Schedule shall be approved before w ork can commence.
f.Project Schedule Update. The Contractor shall submit a monthly update of the Project Schedule updated through the cut- off date for the monthly progress pay estimate, and a projection for completing all remaining activities. A schedule update may show a 108.04 108-7 completion date that is different than the Contract completion date. Approval of this schedule shall not relieve the Contractor of its obligation to complete the work within the Contract Time. When approved, the Project Schedule Update will become the Pro ject Schedule.
g.Weekly Planning Schedule. The Contractor shall submit, in writing, a Weekly Planning Schedule that shows the Contractor’s and all Subcontractor ’s planned activities for a minimum of two weeks immediately following the date of submittal and actual days worked versus planned for the week before the date of submittal. This schedule shall include the description, duration and sequence of work activities and anticipated lane closures for the upcoming two weeks. The Weekly Planning Schedule shall be based on the Project Schedule and may be a time- scaled logic diagram or other standard format as approved by the Engineer. Schedule Submittal requirements for reports do not apply to the Weekly Planning Schedule.
h.Revised Schedule. A Revised Schedule is required in the event of any major change to the work. Examples of major changes are:
1.Significant changes in logic or methods of construction or changes to the critical path.
2.Addition, deletion, or revision of activities required by C ontract Modification Order.
3.Approval of a Contractor submitted Value Engineering Change Proposal.
4.Delays in milestones or project completion.
5.Phasing revisions.
6.When the Engineer determines that the schedule has a fatal flaw; or
7.When the work cannot be constructed as scheduled. The Contractor shall provide a Revised Schedule within 10 days of the Engineer’s written notification and shall include the diagrams and reports as described in subsections 108.03(b) and 108.03(c). Once approved, the Revised Schedule becomes the Project Schedule.
i.Payment. All costs relating to the requirements of this subsection will not be paid for separately but shall be included in the work.
108.04 Payment Schedule. The Contractor shall prepare a payment schedule that shall show
the dollar amount of work the Contractor expects to complete, including Force Accounts, retainage and expected incentive payments, by the progress estimate date each month for the duration of construction. The payment schedule shall be signed by the Contractor’s authorized agent. The payment schedule shall show the dollar amount of work the Contractor expects to complete for every month on the Contract from com mencement of work to Project Acceptance. The fiscal year (July 1 to June 30) totals shall also be shown on the payment schedule. The payment schedule may be prepared using standard spreadsheet software such as MS Excel and submitted in electronic format.
a.Initial Payment Schedule . The Contractor shall submit the certified initial payment schedule within 15 days of the award of the Contract.
b.Payment Schedule Updates. Once each month the Contractor shall submit an update to the Engineer. The update shall be in the same format as the initial payment schedule and shall be submitted to the Engineer by the first day of each month. In each update, estimated monthly dollar amounts shall be revised to show the dollar amount for actual work accomplished that includes actual progress payments made to the Contractor to date and 108.05 108-8work acco mplished b ut not paid. Each update shall show co rrected d ollar amounts of work t o be c omplete d each mo nth through t he Specified Completion D ate as s hown on the C ontractor’s P roject Schedule U pdate. If the updat e has any State Fiscal Year ( July 1 t o June 30) p ayment in ex cess of the encumbrance amount, t he Department m ay, in it s sole discretion, approve the update. I f the Department d oes not a pprove the update th e Contractor shal l either r evise the payment sc hedule or p roceed a t his own r isk. The risk i s either n ot being paid in a timely manner, o r not b eing p aid at all for a ny amo unts over th e encumbrance amount. I f the Contractor p roceeds a t his o wn risk, th en payment for t he at- risk work w ill be dependent upon r atification o f this work b y the State Controller’s Office. If the updat e exceed s the encumbrance amount b ecause of addition al compensable work, and t he Department do es not approve this update, a ny delay t o critical path w ork related to this additional compensable work w ill be considered ex cusab le and c ompensable per subsection 108.08(c), if the Contractor does not proceed at his own risk. If the update exceeds the encumbrance amount because of the Contractor’s accelerated schedule, and the Department does not approve the update, the delay for not performing the work associated with the Contractor’s accelerated schedule in the scheduled Fiscal Year will be noncompensable per subsection 108.08(c), if t he Contractor does not proceed at his own risk. ( c)Failure to Submit Payment Schedule. If the Contractor fails to submit the initial payment schedule, the Contract will not be executed. If a payment schedule update is not submitted by the required date, the Engineer will withhold progress payments until suchtime as the Contractor has sub mitted a current payment schedule.
108.05 Limitation of Operations . The Contractor shall conduct the work in a manner and
sequence to assure the least interference with traffic. The Contractor shall not open up work to the prejudice or detriment of work already started. The Engineer may require the Contractor to finish a section of work before starting any additional sections if the opening of a section is essential to public convenience.
108.06 Character of Workers; Methods and Equipment . The Contractor shall employ
resources for completing work to full completion in the manner and time required by the Contract. All workers shall have skill and experience to perform the work assigned to them. Any person employed by the Contractor or by any subcontractor who does not perform the work in a proper and skillful manner shall, at the written request of the Engineer, be removed by the Contractor or subcontractor and shall not be employed on the projec t without the approval of the Engineer. Should the Contractor fail to remove this person or persons or fail to furnish skilled and experienced personnel for the proper prosecution of the work, the Engineer may suspend the work by written notice until compliance is achieved. All equipment used on the project shall be of size and mechanical condition to meet requirements of the work and to produce a satisfactory quality of work. Equipment used shall not cause injury to the roadway, adjacent property, or other highways. When the methods and equipment to be used are not prescribed in the Contract, the Contractor shall use any methods or equipment that will accomplish the contract work in 108.07 108-9 conformity with the contract requirements. When the methods and equipment to be used are specified in the Contract, other methods and equipment shall not be used in the performance of the work unless the Contractor receives written authorization from the Engineer. If the Contractor desires to use a method or equipment other than specified in the Contract, the Contractor may request approval from the Engineer. The request shall include a full description of the methods and equipment proposed to be used and the Contra ctor’s explanation for the proposed change. The Contractor will be fully responsible for producing work in conformity with contract requirements. If the substituted methods or equipment do not produce results conforming to contract requirements, the Contra ctor shall complete the remaining construction with the originally specified methods and equipment. Deficient work shall be removed, repaired, or replaced to conform with the specified quality by and at the Contractor’s expense. No increase will be made in the basis of payment for the construction items involved nor in contract time when a change in methods or equipment is authorized.
108.07 Workplace Violence. If a representative or employee of the Contractor, or a
subcontractor, commits an act of workplace violence on the project, they shall be sanctioned as provided by the Contractor’s employment policies and, where appropriate, shall be reported to law enforcement authorities. At the request of either the Contractor or the Engineer, the Engineer and the Contractor shall meet to discuss appropriate actions to be taken against the representative or employee. Appropriate action may include removing the representative or employee from the project. If removal is warranted and the Contractor fails to remove the representative or employee, the Engineer may suspend the work by written notice until compliance is achieved.
108.08 Determination and Extension of Contract Time . The contract time is stated in the
Commencement and Completion of Work special provision. The contract time will be used to determine the contract completion date. The Contractor shall not perform construction operations on Saturdays, Sundays, or holidays unless previously arranged and approved. The Contractor shall not perform work on any day of a three -day holiday weekend when the holiday is New Year’s Day, Memorial Day, Independence Day, Labor D ay, or Christmas Day. The Contractor shall not perform work on any day of a four - day holiday weekend when the holiday is Thanksgiving Day. Construction operations shall stop at 12 P .M. the day before the start of the holiday weekend and shall commence the day after the three or four days have passed. When the holiday is New Year’s Day, Independence Day, or Christmas Day and falls on a Tuesday, Wednesday, or Thursday, construction operations shall stop at 12 P .M. the day befor e the holiday and shall commence the next Working Day. The Contractor shall only make emergency repairs and provide proper protection of the work and traveling public on these days.
a.Time Count Contract. When the contract time is on a working day or calendar day basis, the Engineer will furnish the Contractor a weekly statement showing the number of days assessed for the preceding week and the number of days remaining for completion of the Contract. If th e Contractor is in disagreement with the current weekly statement, the Contractor shall submit a request for review of the current weekly statement. Such request shall be made within 30 calendar days of the receipt of the statement a nd shall detail the reasons the statement is believed to be incorrect. When final acceptance has been made by the Engineer as prescribed in subsection 105.21, the daily time charges will cease on working day and calendar day projects. 108.08 108-10 1. Working Day Contract. When the work is on a working day basis, one whole day of contract time will be assessed for each working day that the work can be effectively prosecuted during six hours or more of the day. One -half day will be assessed for each working day that the work can be effectively prosecuted for at least two hours but less than six hours of the day. Contract time will not be assessed when the work can be effectively prosecuted for less than two hours. Saturdays, Sundays, and holidays will be assessed as workdays when the Contractor utilizes such days for prosecuting the work.
2.Calendar Day Contract . When the work is on a calendar day basis, one calendar day of contract time will be assessed for each calendar day from the date that Contract time starts including Saturdays, Sundays, and holidays. Less than full time charges may be made on those days when conditions, which are beyond the control of and unknown to the Contractor, make it impossible to prosecute the work on items controlling the completion of the work with full, normal efficiency. Less than full time charges may be allowed for inclement weather only when the Engineer directs the Contractor not to work for the safety of the traveling public. When less than full time charges are to be assessed, the following procedures will be followed: One whole day of contract time will be assessed for each calendar day that the work is prosecuted during six hours or more of the Contractor’s daily working schedule; one-half day will be assessed for each calendar day that the work is prosecuted for at least two hours but less than six hours of the day; contract time will not be assessed when the work is prosecuted for less than two h ours.
b.Completion Date Contract. When the Contract specifies a completion date, all work under the Contract shall be completed on or before that date. No extension of the completion date will be allowed for inclement weather, foreseeable causes, or conditions under the control of the Contractor. If all work under the Contract is not completed on or before the specified completion date, contract time will be assessed for each additional calendar day per subsection 108.08(a)2.
c.Delay. Any event, action or factor that extends the performance period of the Contract.
1.Excusable Delay : A delay that was beyond the Contractor’s control and was not due to the Contractor’s fault or negligence. The Department may grant a contract time extension for an excusable delay.
A.Compensable Delay : A delay that the Department, not the Contractor, is responsible for entitling the Contractor to a time extension and monetary compensation. Monetary compensation for compensable delays will be made per subse ction 109.10.
B.Noncompensable Delay : An excusable delay that neither the Contractor nor the Department is responsible for that may entitle the Contractor to a contract time extension but no addition al monetary compensation. Contract time allowed for the performance of the work may be extended for delays due to force majeure (acts of God , acts of the public enemy, terrorist acts, fires, floods, area wide strikes, embargoes, or unusually severe weather).
2.Nonexcusable Delay: A delay that was reasonably foreseeable or within the control of the Contractor that the Department will not grant monetary compensation or a contract time extension. 108.08 108-11 3. Concurrent Delay . Independent delays to critical activities occurring at the same time.
A.The Department will not grant a time extension or additional compensation for the period of time that a nonexcusable delay is concurrent with an excusable delay.
B.The Department may grant time but no compensation for the period of time that a noncompensable delay is concurrent with a compensable delay. Delays in delivery of materials or fabrication scheduling resulting from late ordering, financial considerations, or other causes that could have been foreseen or prevented will be considered nonexcusable delays. However, delays caused by fuel shortage or delay in delivery of materials to the Contractor due to some unusual market condition caused by industry ‑wide strike, national disaster, area‑ wide shortage, or other reasons beyond the control of the Contractor that prevent procurement of materials or fuel within the allowable contract time limits will be considered excusable delays.
d.Extension of Contract Time. The Contractor shall orally notify the Engineer as soon as the Contractor recognizes a potential project delay. The Contractor or Engineer shall document the discussion in writing. This discussion and documentation are not considered an official notice of a delay. The Contractor shall provide a written notice of delay within seven days of determining the need for additional contract time. The notice of delay shall describe the nature and specific cause of the delay. Failure to submit the written notice of delay with in seven days constitutes a waiver of entitlement to additional time or compensation. The Contractor shall submit the time extension request and supporting analysis within 30 days of the written delay notice. The request shall include a schedule analysis with all information needed to support the time extension request pursuant to one of th e following methods including an explanation for selecting that method:
1.Time Impact Analysis (TIA) for all forward -looking analyses of time impacts following the guideline AACE® International Recommended Practice N o. 52R-06 Prospective Time Impact Analysis – As Applied in Construction.
2.Forensic Schedule Analysis for all time impacts absorbed into the schedule following the AACE® International Recommended Practice 29R -03 Forensic Schedule Analysis.
3.Other acceptable method of schedule analysis, as approved by the Engineer. The analyses shall show a delay to the critical path in order to obtain a contract time extension. The Contractor shall demonstrate that efforts were made to avoid the delay by resequencing the work or by using other reasonable alternatives. Failure to sub mit the documentation to support the time extension request within 30 days of the Contractor’s written notice of delay constitutes a waiver of entitlement to additional time or compensation. The Engineer’s review of the time extension request will not exce ed 15 days. The schedule included in the request shall be per subsection 108.03(c). The Engineer will base a determination of an allowable contract time extension on the current “Approved, no exceptions taken” or “Approved- as-Noted” Project Schedule that shall have a data date within 30 days before the alleged delay, the supporting documentation and schedule analysis submitted by the Contractor, and any additional relevant information available. 108.09 108-12 The Contractor’s assertion that insufficient contract time was specified is not a valid reason for an extension of contract time. Adding activities to or changing logic on a Project Schedule Update shall not constitute supporting documentation of a delay request justification. The Contractor shall submit a justification for determination of a contract time extension separately from the Project Schedule Update. Approval of a Project Schedule U pdate or Revised Schedule will not constitute approval of a contract time extension. When the Engineer grants a contract time extension, the revised Contract Completion date will be in effect as though it were the original contract date. The Contractor’s failure to have an “Approved” or “Approved -as- Noted” current project schedule in place will preclude the Department from approving a Contractor’s time extension request.
108.09 Failure to Complete Work on Time . A daily charge will be made against the
Contractor for each calendar day, including free time, that any work remains uncompleted after the elapse of contract time. This daily charge will be deducted from any money due the Contractor. This deduction will not be considered a penalty, but as liqu idated damages. The schedule of liquidated damages set forth below is an amount, agreed to by the Contractor and the Department, as reasonably representing additional construction engineering costs incurred by the Department if the Contractor fails to complete performance within the contract time. Table 108- 2 LIQUIDATED DAMAGES Original Contract Amount ($); from more than , to, and including Liquidated Damages per Calendar Day ($) 0 -1,000,000 1,400 1,000,000 – 2,000,000 2,500 2,000,000 – 6,000,000 4,500 6,000,000 – 9,000,000 8,000 9,000,000 – 20,000,000 8,800 Above 20,000,000 12,500 Due account shall be taken of any adjustment of the contract time for completion of the work granted under the provisions of subsection 108.08. Permitting the Contractor to continue and finish the work or any part thereof after elapse of contract time will not operate as a waiver on the part of the Department of any of its rights under the Contract. Deductions assessed as liquidated damages under this subsection shall not relieve the Contractor from liability for any damages or costs resulting from delays to other contractors on the project or other projects caused by a failure of the assessed Contrac tor to complete the work according to contract times.
108.10 Default of Contract.
a.The Engineer may send a written notice of intent to find the Contractor in default to the Contractor and the Surety by certified mail for any of the reasons listed below. 108.10 108-13 The notice will describe the conditions causing the impending default, advise them of the actions required for remedy, and state that if the conditions have not been corrected within 10 days of receipt of the notice, CDOT will find the Contractor in default. The Department may send a written notice of intent under this part (a) if the Contractor:
1.Fails to begin the Contract work within the time specified to begin work, or
2.Fails to perform the Contract work with sufficient resources to assure its timely completion, or
3.Discontinues the Contract work, or
4.Fails to resume discontinued Contract work, or
5.Becomes insolvent, is declared bankrupt, commits an act of bankruptcy or insolvency, allows a final judgment to remain unsatisfied for a period of 10 calendar days, makes an assignment for the benefit of creditors, or
6.Fails to comply with the Contract regarding minimum wage payments, Disadvantage Business Enterprise ( DBE) requirements, or Equal Employment Opportunity ( EEO) requirements, or
7.Is a party to fraud. If the Contractor fails to correct the conditions identified in the notice of intent to find the Contractor in default within 10 calendar days of receipt, the Department may serve the Contractor with an immediate notice of default and take prosecution of the work from the Contractor. Copies of the default notice will also be sent, by certified mail, to the Contractor and the Surety .
b.The Engineer may send a written notice of intent to find the Contractor in default to the Contractor and the Surety by certified mail for the reason listed below. The notice will include a suspension of work , which will require the Contractor to cease work on the Contract Items that are unacceptable. The notice will describe the conditions causing the impending default, advise the Contractor of the actions required for remedy and state that if the conditions have not been corrected within 10 days of receipt of the notice, CDOT will find the Contractor in default. The Department may send a written notice of intent under this part (b) if the Contractor fails to perform the work to Contract requirements or neglects or refuses to correct or remove and replace rejected materials or unacceptable work. The Contractor shall not resume work on the unacceptable Contract Items until the following conditions have been met:
1.The Contractor shall submit a written proposal to the Engineer outlining the procedures that will be followed by the Contractor to correct the unacceptable conditions, and
2.The Engineer and the Contractor shall meet to discuss the written proposal; and
3.The Engineer will issue written permission for the Contractor to commence work. If the Contractor fails to meet these three conditions within 10 calendar days of receipt of the notice of intent to find the Contractor in default, or if at any time after the Contractor resumes work, the work does not meet Contract requirements or the Contractor again neglects or refuses to correct or remove and replace rejected materials or unacceptable work, the Department may serve the Contractor with an immediate notice of default and take prosecution of the work from the Contractor. Copies of the default notice will also be sent, by certified mail, to the Contractor and the Surety . 108.11 108-14 (c) In the case of default under either subsection 108.10(a) or 108.10(b):
1.The Department will revoke the Contractor’s Prequalification. If the Department chooses to rebid the remaining Contract work on this project, the Contractor will not be allowed to submit a bid for this work.
2.The Department may appropriate or use materials at the project site and contract with others to complete the remaining Contract work.
3.The Department will determine the methods used for completion of the Contract.
4.Resulting costs and charges incurred by the Department will be deducted from payments owed the Contractor. If such costs exceed the payment owed the Contractor, the Contractor and Surety shall reimburse the Department for these costs. These costs and charges may include but are not limited to cost of Contract completion, including designing, advertising, bidding and awarding the remaining work and liquidated damages or disincentives.
d.If the notice of default is determined to be in error, the rights and obligations of the parties shall be the same as if the Contract had been terminated per subsection 108.10. Damages for improper notice of default may be awarded accordingly.
108.11 Termination of Contract.
a.Termination Notice. The Department may terminate work under the Contract in whole or in part if the Engineer determines that termination is in the Department’s best interest. Contract termination will be initiated by the Engineer’s written Contract Termination Notice to the Contractor. The notice will specify the effective date.
b.Canceled Commitments. The Contractor, after receiving the Contract Termination Notice, shall cancel any outstanding commitments for procurement of materials, supplies, equipment, and miscellaneous items. In addition, the Contractor shall use reasonable effort to cancel or diver t any outstanding subcontract commitments to the extent they relate to any work terminated. With respect to such canceled commitments the Contractor shall: (1) Settle all outstanding liabilities and all claims arising out of these canceled commitments. Such settlements will be approved by the Engineer and shall be final; and
2.Assign to the Department all of the rights, title and interest of the Contractor under the terminated orders and subcontracts, as directed. The Department will then have the right to settle or pay any or all claims arising out of the termination of the se commitments.
c.Termination Claim. The Contractor shall submit the termination claim to the Engineer within 90 days after the termination notice effective date. During the 90- day period, the Contractor may make a written request for a time extension in preparing the claim. Any time extension must be approved by the Engineer. If the Contractor fails to submit the termination claim within the time allowed, the Engineer may determine the amount due the Contractor by reason of the termination.
d.Payment. Subject to subsection 108.11(c) above, the Contractor and Engineer may agree upon the whole or any part of the amount to be paid to the Contractor because of the termination. The amount may include reasonable cancellation charges incurred by the Contractor . The amount may also include any reasonable loss upon outstanding commitments for subcontracts that the Contractor is unable to cancel, provided the Contractor has made reasonable effort to divert the commitments to other activities. 108.11 108-15 The amount agreed upon shall be embodied in a Contract Modification Order and the Contractor shall be paid that amount. Payments claimed and agreed to pursuant to termination shall be based on the Contract unit prices. Payment for partially completed lump sum items may be made in the proportion that the partially completed work is to the total lump sum item. Where work perf ormed is of a nature that it is impossible to separate the costs of uncompleted work from completed units, the Contractor will be paid the actual cost incurred for the necessary preparatory work and other work accomplished. The Department may from time to time, under terms and conditions it may prescribe, make partial payments against costs incurred by the Contractor in connection with the contract termination. The total of such payments shall not exceed the amount, as determ ined by the Engineer, the Contractor will be entitled to hereunder.
e.Disposition of Work and Inventory. The Contractor shall transfer title and deliver to the Department, as directed, such items which, if the Contract had been completed, would have been furnished to the Department including:
1.Completed and partially completed work; and
2.Materials or equipment produced or in process or acquired in connection with the performance of the work terminated by the notice. Other than the above, any termination inventory resulting from the contract termination may, with written approval of the Engineer, be sold or acquired by the Contractor under the conditions prescribed by and at prices approved by the Engineer. The proceed s of any such disposition shall be applied to reduce any payments to the Contractor under the Contract or shall otherwise be credited to the cost of work covered by the Contract or paid in a manner as directed. Until final disposition, the Contractor shall protect and preserve all the material related to the Contract that is in the Contractor’s possession and that the Department has or may acquire an interest.
f.Cost Records. The Contractor agrees to make cost records available to the extent necessary to determine the validity and amount of each item claimed.
g.Contractual Responsibilities. Termination of a Contract or portion thereof shall not relieve the Contractor of contractual responsibilities for the work completed, nor shall it relieve the Surety of its obligation for and concerning any just claim arising out of the work performed. 108.11 108-16 THIS PAGE INTENTIONALLY LEFT BLANK 109.01 109-1 SECTION 109 MEASUREMENT AND PAYMENT
109.01 Measurement of Quantities . All work completed under the Contract will be measured
by the Engineer according to United States standard measure (English units). A station when used as a definition or term of measurement will be 100 linear feet. The method of measurement and computations to be used in determination of quantities of material furnished and of work performed under the Contract will be those methods generally recognized as conforming to good engineering practice. Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and deductions will not be made for individual structures having an area of 9 square feet or less. Unless otherwise specified, transverse measurements fo r area computations will be the neat dimensions shown on the plans or as ordered in writing by the Engineer. Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions. Items that are measured by linear foot, such as pipe culverts, guardrail , underdrains , etc., will be measured parallel to the base or foundation that the structures are placed, unless otherwise shown on the plans. In computing volumes of excavation and embankment, the average end area method or the method incorporated into the Department’s computer earthwork program will be used. The term “ga uge,” when used in connection with the measurement of plates , will mean the
U.S. Standard gauge . When the term “ga uge” refers to the measurement of wire, it will mean the wire gauge specified in ASTM A510. The term “ton” will mean the short ton consisting of 2 ,000 pounds avoirdupois. Materials measured or proportioned by weight shall be weighed on accurate scales. Scales shall be accurate within the allowable tolerances as prescribed by State law. The scales shall be tested for accuracy by the Colorado Department of Agriculture or an approved Colorado Department of Agriculture vendor at least once each year, each time the scales are relocated, and as often as the Engineer may deem necessary. Scales shall be furnished by the Contractor, or the Contractor may utilize commercial scales. Scales shall be operated according to the Colorado Department of Agriculture’s regulations. Weighers, scales, scale tickets, scale house, and verification of the scales’ accuracy will not be measured and paid for separately but shall be included in the work. The Contractor may use either certified hopper scales or certified platform scales. When platform scales are used to weigh vehicles carrying material paid for by weight, a certified weigher shall weigh each vehicle. Hopper scales used to directly measure material paid for by weight shall be operated by certified weighers and provide an accurate net weight.
