DESCRIPTION
629.01.01 General. This work consists of time related overhead incurred by the Contractor and by any joint
venture partner, subcontractor, supplier , or other party associated with the Contractor. Time related overhead costs include field and home office overhead that are in proportion to the time required to complete the work. Time related overhead does not include costs that are not related to time, including but not limited to; mobilization, licenses, permits, and any other charges incurred only once during the contract. CONSTRUCTION
629.03.01 General. Field office overhead expenses include time related costs associated with the normal an d
recurring operations of the construction project, and shall not include costs directly attributable to any of the work of the contract. Such time related costs include, but are not limited to; the salaries and benefits of project managers, general superi ntendents, field office managers and other field office staff assigned to the project, and rent, utilities, maintenance, security, supplies and equipment cos ts of the project field office. Home office overhead or general and administrative expenses refer to the fixed costs of operating the Contractor's business. Such costs include, but are not limited to, general administration, insurance, personnel and subcontract administration, purchasing, accounting, and project engineering and estimating. Home office overhead shall exclude expenses specifically related to other contracts or other businesses of the Contractor, equipment coordination, material deliveries, and consultant and legal fees. METHOD OF MEASUREMENT
629.04.01 Measurement. Time related overhead will be measured by the day for each eligible working day
assessed to the contract, however, not to exceed the number of working days specified in Subsection 108.02, plus or minus authorized changes. Time related overhead will not be measured for payment during suspensions of work ordered in conformance with the provisions in Subsection 108.04 or 108.06, or any suspensions mutually agreed upon between the Engineer and the Contractor. In the event of early completion of the contract, the number of days measured for payment will be the number of working days specified in Subsection 108.02, plus or minus authorized changes. In the event a Value Engineering Proposal is submitted, and is subsequently approved, which provides for a reduction in the number of contract working days, the net savings in the cost of time related overhead due to the decreased working days will be eligible for the provisions of Subsection 105.19 . The provisions in Subsection 104.02 shall not apply to time related overhead. BASIS O F PAYMENT
629.05.01 Payment. The accepted quantity, measured as provided above, will be paid for at the contract price
per unit of measurement for the pay item listed below that is shown in the proposal. Payment will be full compensation for the work pres cribed in this Section. The dollar amount paid per eligible working day will be the contract bid price or 20% of the original contract amount divided by the number of working days specified in Subsection 108.02, whichever is less. Upon completion of all w ork on the project, payment for any amount due the Contractor will be made. Payment will be made under: Pay Item Pay Unit Time Related Overhead ................................ ................................ ..................................................................................................... Day If the quantity of time related overhead, measured as provided above, exceeds 125% of the original contract quantity and the Department provides a written request, submit an audit examination and report of actual overhead 629 TIME RELATED OVERHEAD costs within 60 days of such request. Have said audit examination and report performed by an independent Certified Public Accountant in conformance with the requirements of the American Institute of Certified Public Accountants Attestation Standards. The audit examination and report shall depict project and company -wide financial records and shall specify the actual overall average daily rates for both field and home office overhead for the entire duration of the project, and whether the costs have been properly allocated. Do not include unallowable costs, as determined in the Federal Acquisition Regulations, 48 CFR, Chapter 1, Part 31, as part of the field and home office overhead rates. The examination shall determine if the rates of field and home office overhead adhere to the following:
1.Are allowable in conformance with the requirements of the Federal Acquisition Regulations, 48 CFR, Chapter 1, Part 31;
2.Are adequately supported by reliable documentation; and
3.Are related solely to the project under examination. Upon written request, make financial records available for audit by the State for the purpose of verifying the actual rate of time related overhead established in the submitted audit examination and report. The actual rate of time related overhead established in the su bmitted audit examination and report will be subject to approval. Payment for time related overhead in excess of 125% of the original contract quantity will be made at the approved rate. When requested by the Department, the cost of performing an audit ex amination and submitting the report shall be borne equally by the Contractor and the Department on a 50- 50 basis. Such cost will be determined according to Subsection 109.03. SECTION 632 PERMANENT PAINTED PAVEMENT MARKINGS DESCRIPTION
632.01.01 General. This work consists of applying permanent pavement markings on the completed pavement.
MATERIALS
632.02.01 General. Material shall conform to the following Sections:
Traffic Paint ................................ ............................................................................................................................................ Section 729 Traffic Beads .......................................................................................................................................................................... Section 730 Use epoxy , waterborne, or polyurea traffic paint materials as specified for the pavement striping items shown in the proposal. CONSTRUCTION
632.03.01 General. Perform stakeout for the location of the pavement striping according to the plans, Special
Provisions, these specifications, and as directed. The location of striping shall closely parallel the striping pattern depicted on the plan sheets. Place markings in proper alignment. Do not deviate from alignment by more than 25 mm (1 in.) per 60 m (200 ft) of roadway. Do not exceed 50 mm (2 in.) maximum deviation and do not create abrupt deviations. Remove and replace markings not placed in proper alignment or pattern by approved met hods. Place striping in the direction of traffic flow. Protect the pavement striping from public traffic until dry by the use of traffic cones or by any other approved means. Painted pavement striping shall be 100 mm (4 in.) wide unless otherwise noted. The paint pattern for a broken line shall consist of a 3.05 m (10 ft) stripe and a 9.14 m (30 ft) gap. The paint pattern for a dotted line at lane drops shall consist of a 0.91 m (3 ft) stripe and a 3.66 m (12 ft) gap. The paint pattern for dotted lines (cat tracks) at intersection turn lane lines and at the end of bike lanes at intersections shall consist of a 0.61 m (2 ft) stripe and a 1.22 m (4 ft) gap. Place permanent striping materials (or temporary markings if allowed) at the end of each day’s pavi ng operations or before allowing public traffic on any final plantmix bituminous surface course. Protect paint lines, symbols, and legends from tracking during the setting period by closing off the wet markings from traffic, us ing a convoy of moving vehic les to prevent traffic crossing the markings, or saturation of the markings with glass beads to prevent tracking.
632.03.02 Striping Equipment. Use only equipment designed for epoxy, waterborne, or polyurea traffic paints.
Use equipment with a system capable of spraying both yellow and white paint, mounted on a truck of sufficient size and stability, and having an adequate power source to produce lines of uniform dimension and prevent application failure. Use equipment capable of placing stripes on the lef t and right sides and of placing two lines simultaneously with either line in a solid or intermittent pattern in yellow or white, and of applying glass beads at the proper rate. Guns shall be in full view of operators at all times. Provide equipment with a metering device to register the accumulated installed footage for each gun, each day. Include at least one operator in each vehicle who is a technical expert in equipment operations and application techniques. Use equipment designed so that the pressure gauges for each pump are constantly visible to the operator at all times during its operation so that any fluctuation and pressure difference can be monitored immediately. Equip each paint tank with a mechanical agitator. Application equipment for epoxy paint shall have a static mixer unit for proper mixing of the two components of the epoxy paint material. Application equipment for polyurea paint shall have a static mixer unit for proper mixing of the two components of the polyurea paint material or shal l include the impingement mix, airless spray application system for liquid
