a.General.
1.With the Engineer’s approval, the Contractor’s surveying operations may begin after the contract is signed, but prior to issu ing the Notice to Proceed.
2.Surveying Personnel. Before performing any survey ing operations on the proj ect, inform the Engineer of the Contractor’s personnel responsible for land surveying, construction surveying and staking. Provide a Land Surveyor, trained and experienced in the construction staking and licensed by the Kansas State Board of Technical Professions according to Kansas Statut es to perform the required land surveys, the setting of all section corners, right-of-way survey monuments and reference point monuments set on the right-of way lines.
3.Provide surveying equipment that complies with the following tolerances: 802 - CONTRACTOR CONSTRUCTION STAKING
800-3 Slope Staking: Horizontal and Ver tical tolerance of ± 0.10 feet (per KDOT Construction Manual -
Cross Sections 3.06.02). Use a GPS system, a Total Station, or a Level & Transit. Finish Staking: (grade hubs, blue tops, string lines, etc.) and Structures: Horizontal = ± 0.05 feet; Vertical = ± 0.01 feet (per KDOT Construction Manual, subsection 3.09 - Finishing Stakes, Part III). For Horizontal, use a GPS system or a Total Station. For Vertical, use a Level or Total Stations. Do not use GPS for Vertical. Critical Bridge Member Staking: Horizontal = ± 0. 02 feet; Vertical = ± 0.01 feet (Vertical as per Construction Manual, subsection 3.09 - Finishing Stakes, Part III). For Horizontal, use a GPS system or a Total Station. For Vertical, use a Level. See subsection 802.3c.(2) for Critical Bridge Member Staking. Right of Way Survey Monuments: For relative precision of all R/W Survey Monuments, comply with the precision expressed in the Kansas Minimum St andards for Boundary Surveys from the project coordinate data. Use a GPS system or Total Station. Project Control Points: The relative precision of any project control point ± 0.05 feet from the project coordinate data. Use a GPS system or Total Station. Field Notes: For all land surveying and construction staking, record 2 measurements for verification in the field notes for all PLSS corners and all project control points. GPS equipment: Take 2 GPS measurements at a minimum interval of 2 hours with the base station at 1 or 2 project control points. Include in the field survey notebooks a copy of the site calibration. The site calibration includes an area extending a minimum of 200 feet beyond the beginning and ending of the project and the construction limits furthest offset to the left and right of the project centerline. Take a minimum of 4 calibration points or as directed by the Engineer. Use the sum of the maximum residual of the site calibration and the delta of the point being staked. Total Stations: To verify the tolerances, record tota l station measurements from 2 project control points (set-up or backsight) to the point being established. Use the average of the 2 resulting coordinate values for the point being staked for the specified tolerances. Levels: Record in the field notes a turn through eac h project benchmark as they are encountered during staking activities (per KDOT Construction Manual, subsection - 3.23.05 – Elevations, Part III). Control Stakes: Do not perform vertical control using GPS.
4.Before proceeding with the field surveys, provide the Engineer with a written report of any errors or apparent discrepancies found in previous surveys or th e Contract Documents. The Engineer will provide the corrections or necessary interpretations. Correct any deficient engineering la yout or construction work that is the result of inaccuracies in the Contractor’s surveys or staking operations, or the failure to report inaccuracies found in the work previously done by KDOT, at no additional cost to KDOT.
5.The Engineer will perform final checks, measurem ents and surveys involving the determination of any pay quantities. The Engineer may check the accuracy and control of the Contractor’s construction staking at any time throughout the duration of the project.
b.Land Surveying.
1.Before any construction activity starts in the im mediate area of an endanger ed Public Land Survey System (PLSS) corner, recover all endangered secti on corners and accessories of the PLSS on the project. Endangered PLSS corners are those as defined by Kansas Statutes and/or shown in the Contract Documents as lying within the range from the pr oject centerline to a distance 100 feet out side the construction limits, throughout the length of the project. Establish a minimum of 3 reference ties for each endangered PLSS corner. Each reference tie shall be a direct measurement to a precise (hard define d) point. Specify slope or horizontal measurement. Complete a Land Survey Referen ce Report marked as a "Notice of Endangerment Activity" for each endangered PLSS corner. File the reports with the approp riate governmental custodian responsible for maintaining those records, as required by Kansas Statutes. Provide the Engineer with copies of the completed reports.
2.Before any construction activity starts in the immediate area, clearly esta blish the right-of-way as shown in the Contract Documents. If the R/W Survey Monuments are set initially, determine each monument’s position with the project coordinates, pr oject stationing and offset. Provide the Engineer with a written report of each monument’s position for each R/W Survey Monument set supplementary to thos e shown in the Contract 802 - CONTRACTOR CONSTRUCTION STAKING
800-4 Documents including additional monuments, monuments requested by the Engineer and monuments offset near
obstructions.
3.Recover and verify, or reset all of the PLSS corners previously reported as endangered PLSS corners. Verify the top of all PLSS corners monuments are ¼ to ½ inch below the finish grade on concrete pavement and 4 to 6 inches below the finish grade on asphalt pavement. Establish a minimum of 3 reference ties for each of the PLSS corners. Each reference tie shall be a direct measurem ent to a precise (hard defined) point. Specify slope or horizontal measurement. Complete a Land Survey Reference Report marked as a Notice of Completion of Endangerment Activity and Report of Restoration for each restored PLSS corner pr eviously reported as endangered. File the reports with the appropriate governmental custodian responsible for maintaining those records, as required by Kansas Statutes. Provide the Engineer with copies of the completed reports.
4.Before the completion of project construction, set all of the R/W Survey Monuments shown in the Contract Documents. If the R/W Survey Monuments were set initially, visua lly inspect each R/W Survey Monument to determine if it was either disturbed or destroyed. Rese t all of the R/W Survey Monume nts that are determined as disturbed or destroyed, at no cost to KDOT. Determine each reset monumen t’s position with both the project coordinates and the project stationing and offset. Provide the Engineer with a written re port of all right-of-way survey monuments set.
c.Construction Surveying and Staking.
1.General. Check alignment and reference or re-re ference all necessary control points. Establish or re-establish project centerline. Run a level circuit to check or re-establish plan benchmarks; set other benchmarks as needed. Take original cross-sections that are not incorporated in the plans. Stake or re-stake right-of-way where needed (to be done by a Licensed Professional Land Surveyor). Perform all construction layout and reference staking necessary for the proper control and satisfactory completion of all structures, grading, paving, drainage and all other appurtenances required for the completion of the work and acceptance of the project. Construction of ditches and other planned excavation and embankment designated in the Contract Documents may be performed by Global Positioning System (GPS) controlled grading equipment, according to the Contract Document s and this specification. GPS controlled grading equipment does not eliminate the need for finish staking or blue top staking. Once a week, provide the Engineer with documentation (on a preapproved form) verifying machine calibration to monitor, verify, adjust and compensate for the wearing su rface of the cutting edge of the machine being utilized.
a.GPS Equipment. Use GPS controlled grading equipment capable of meeting the end results specified in the Contract Documents. The Engineer may require verification of shot locations. This could be by witnessing the Contractor take shots with GPS Rover, etc. Make available a GPS Rover (same brand and type being used on the project) to the Engineer for review of the work, as needed during normal working hours. This GPS Rover will be stored and maintained by the Contractor. In addition, provide a minimum of 8 hours of formal training on the use of the Contractor’s GPS systems to the Engineer, prior to beginning any GPS controlled machine grading. Conduct training to provide the Engineer with an understanding of the equipment, software and electronic data being used by the Contractor. For multi-y ear projects, the Engineer may require informal refresher-training on the use of the GPS Rover.
b.Electronic Design Files/GPS Model. When available, KDOT will provide Electronic Design Files for the project. Convert the files provided by KDOT into the format required by the Contractor’s system and equipment. Conform to the typical sections. Notify KDOT Design and the Field Office administering the contract, in writing, of any errors, omissions, ambiguities, or perceived inadequacies found in the Electronic Design Files provided by KDOT. Make no claim on the contract under SECTION 104 , for additional money, additional time or both because the KDOT produced plans differ from drawings generated from the Electronic Design Files, even if the Contractor did not manipulate the Electronic Design Files before generating the GPS Model. Accept sole respon sibility for the adequacy and accuracy of all Contractor-generated, subcontractor-generated, or supplier-generated documents or GPS Models 802 - CONTRACTOR CONSTRUCTION STAKING
800-5 used on the project. Assume the risk of errors and omissions resulting from software conversions,
Electronic Design File manipulation or other Electronic Design File creation used by the Contractor, subcontractors, supplie rs or any combination thereof. The GPS Model the Contractor generates from the Electronic Design Files may differ from the Contract Documents. The Contractor assu mes the risk of such discrepancies. KDOT printed plans controls over the related Electronic Design File(s) which controls over the Contractor’s GPS Model. (c) GPS 3D Model. Before beginning any GPS controlled machine grading, provide the KDOT Field Office and KDOT Design with an electronic copy of the GPS 3D Model created for that use. In addition to the GPS machine control, provide centerline stakes, slope st akes and grade stakes from the beginning thru the end of the project, at 500-foot intervals on straight runs, and at 250- foot intervals on curves, transitions, intersections , interchanges and break points. The Engineer may require closer staking intervals for other locations, such as transition areas. GPS controlled machine grading does not eliminate the need for finish staking or blue top staking. The Engineer may review the Contractor’s GPS machine control grading results, surveying calculations, records, field procedur es and actual staking at any ti me. If the Engineer determines the work is not meeting the required horizontal and vertical tolerances, see Unacceptable Work, SECTION 105 . Contractor delays or errors due to operating the GPS machine control system will not result in any adjustment under SECTION 104 , for additional money, additional time or both.
2.Bridge. Prior to construction, set project control points and Critical Bridge Element control points for the horizontal and vertical location of the Critical Bridge Element features under the supervision of a Licensed Professional Land Surveyor. Critical Br idge Elements include, but are not limited to the features listed in TABLE
802-1 .
Prior to construction, provide an independent survey performed under the supervision of a different Licensed Professional Land Surveyor to check the accuracy of the original su rvey of project control points and locations of the Critical Bridge Elements features. Report any differences or discrepancies to the Project Engineer. Resolve any differences or discrepancies, prior to construction of the Critical Bridge Elements. After the Critical Bridge Elements have been constr ucted, provide a survey under the supervision of a Licensed Professional Land Surveyor to verify the locatio ns and elevations of the Critical Bridge Elements. All surveys shall be within the tolerances for that bridge element allowed in the Contract Documents. Report any discrepancies in excess of th e tolerances to the Project Engineer.

3.Documentation. Provide and main tain a current copy of all field surv ey notebooks at the project site at all times. Produce the original field survey notebooks for inspection upon request by the Engineer. Include a 802 - CONTRACTOR CONSTRUCTION STAKING
800-6 detailed list of any abbreviations, codes, formatting or othe r nomenclature contained in the notebooks to facilitate
clarity of the notes. Provide either on e or a combination of both of the following types of notes, as directed by the Engineer: Provide standard, bound field notebooks where the handwritten field notes are indexed and kept in a clear, orderly and neat manner consistent with stan dard surveying practices and according to KDOT’s procedures. Provide a legible ASCII file for elect ronic field notes where the “theore tical (calculated) point” can be checked against the “established point” set in the field. This method allows for a check of the inverse distance and direction for error tolerance. This procedure should be utilized for points with elevations. Before any construction staking begins, the procedures for all electronic field notes must be approved by the Engineer.
4.Monuments. Upon completion of the surfacing, recover and verify or reset all of the field survey monuments (such as P.I.’s, P.O.T.’s, P.C.’s, P.T.’s, P.O.S.T.’s,) on the project centerlines or baselines, as shown in the Contract Documents. Verify that the top of the field survey monuments are set a maximum of ½ inch below the finish grade on concrete pavement, or a maximum of 6 inches below the finish grade on asphalt pavement. Verify the accuracy of the locations of all fi eld survey monuments versus those of the project centerlin es or baselines shown in the Contract Documents. Establish a minimum of 4 reference ties for each of the field survey monuments on the project centerlin es or baselines.
5.Reports. Provide a written report to the Engineer indicating the descriptions of all field survey monuments and their 4 reference ties, regardless if the information in the Contract Documents was revised or not. Include in the report “station calls” for each of the field survey monuments (such as P.I.’s, P.O.T.’s, P.C.’s, P.T.’s, P.O.S.T.’s) on the project ce nterlines or baselines shown in the Contract Documents. Recover and verify all of the project benchmarks shown in the Contract Documents. Establish permanent replacement benchmarks for all project benchmarks that we re destroyed during the cons truction using one of these methods: A benchmark disc “set in pla ce” on new concrete structure. A benchmark disc “drilled and grouted” on existing concrete structure. A benchmark disc set in the top of a concrete footing (6-inch diameter x 4-foot depth into the ground, minimum) cast in place. As directed by the Engineer. Stamp the benchmark caps with the “Project Number ” and the permanent repl acement benchmark number as a letter designation following the benchmark it is replacing (i.e.: destroyed BM #21 is replaced by BM #21A). Without exception verify that the maximum spacing between benchmarks is a maximum of 30 feet in vertical difference, 500 feet in horizontal dist ance in urban areas or 1500 feet in horizontal distance in rural areas. Provide the Engineer with a written report of all post project benchmarks, listing the benchmark number, elevation, project stationing and offset, and a complete description of the monument type and its physical location. Include in the report, all of the remaining benchmarks sh own in the Contract Documents, the permanent replacement benchmarks and the remaining additional “construction benchmarks” used for the staking of the project. Do not include in the report any “temporary benchmarks” used for the construction staking of the project that are classified as “temporary” or “degradable” in nature.
d.Right-of-Way Survey Monuments. Set all right-of-way survey monuments on and along the KDOT right-of-way lines at these locations: All P.I. locations along normal/tangent sections. All P.C. and P.T. locations along curved sections. At an offset where a physical obstr uction impedes the exact location. Set all Reference Point monuments on and along KDOT right-of-way at these locations: At points a maximum of 1320 feet apart where the right-of-way is straight, or on a continuous horizontal curve of constant radius. At the crest of a sharp hill or th e shoulders of a large/rounded hill. At radial/perpendicular lines to all horizontal change s in the project centerline alignment (i.e., P.C. and P.T. offsets). As directed by the Engineer. 802 - CONTRACTOR CONSTRUCTION STAKING 800-7 Set all right-of-way survey monuments according to the Contract Documents. Fasten the R/W sign to the witness post in this sequence: bolt, flat washer, sign, post, flat washer, lock washer and nut. When conditions warrant, the Engineer may adjust the specified depth. When it is impossible to set a right- of-way survey monument at the exact point because of an obstruction, set the right-of-way survey monument along the right-of-way line, or the extended right-of-way line, on both sides of the obstruction. Use 1-foot increments for the offset distance from the exact point to the set monument. Field stamp th e aluminum cap “O/S” either below or to the right of the “R/W” stamping. Provide the Engineer with a complete list of the lo cations of all right-of-way survey monuments set.
e.Concrete Footings. When required, construct footings of commercial grade conc rete according to the Contract Documents. Extend the top of the footing slightly above the ground line and steel trowel to a smooth finish with a slope to drain away from the post.
f.Monument Box. When required, install the monument box and survey marker by a Licensed Professional Land Surveyor as shown in the Contract Documents. If the monument box is installed in concrete pave ment, use the same mix as used in the pavement.
g.As-Built Construction Plans and Survey Notebooks. Upon completion of the project, provide the Engineer with a set of as-built constructio n plans with the following information: The monument descriptions and the 3 refere nce ties for all restored PLSS corners. The monument descriptions and the 4 reference ties for all field survey monuments on the project centerline or baseline. The project stationing and offset of the final position of every right-of-way survey monument and project alignment reference point that was set. The permanent replacement benchmarks and remain ing construction benchmarks with benchmark number, project station and offset, elevation and description. Deliver the original field survey notebooks to the Engineer upon completion of the project. 802.4 MEASUREMENT AND PAYMENT The Engineer will measure each right-of-way survey monument, benchmark monument (concrete cylinder) and monument box as a unit. Contractor construction staking w ill be measured by the lump sum. The Engineer will make par tial payments according to TABLE 802-2 . The Engineer may adjust the TABLE 802-2 , based on Contractor’s progress and project complexity. TABLE 802-2: CONSTRUCTION STAKING PAYMENT SCHEDULE* Percent of Original Contract Amount Completed Percent of Bid Item Paid Work Started 25% 5% 40% 25% 60% 50% 80% 70% 95% All field books, As-Built construction plans ( subsection 802.3g. ) and records have been submitted to the Engineer. 100% *Until all appropriate information is recei ved, and the bid item is 100% paid, the work is considered incomplete and subject to SECTION 108 .

If the sa me lab is used for all the projects, it will only be paid for on the project with the largest or iginal contract dollar am ount, and the bid item will be underrun from the other projects. 803.4 MEASUREMENT AND PAYMENT If the Engineer informs the Contractor at the pre-cons truction conference that the field office or field office and laboratory are not required, the Engineer will underrun this item. The Engineer will measure each field office and field office and laboratory. The Engineer will measure each unit on each project only once, even if the unit is relocated. On KDOT-tied projects, the Engineer will measure each unit only once on one of the KDOT-tied pr ojects, even when the unit is used on all related KDOT-tied projects. If the unit is shown on more than one project, it will only be measured and paid for on the project with the largest original contract dolla r amount, and the bid item underrun from the other projects. A Field Office and Laboratory (Type A) may be subs tituted for and measured for payment as a Field Office and Laboratory (Type B), a Field Office and Laboratory (Type C) or a Field Office. A Field Office and Laboratory (Type B) may be substituted for and measured for payment as a Field Office and Laboratory (Type C). Payment for "Field Office and Laboratory" and "Fie ld Office" at the contr act unit prices is full compensation for the specified work. Th e contract unit prices for the various types of field offices and laboratories will govern, regardless of the number of units used on the project. The Engineer will make partial payments according to TABLE 803-2 . 803 - FIELD OFFICE AND LABORATORY

If the Engineer determines that broa dband internet service is not available for "Field Office and Laboratory (Type A)", provide a fax mach ine, at no additional cost. If the Engineer determines that broadband internet service is unnecessary for "Field Office and Laboratory (Type A)", the Engineer will reduce the contract unit price for this item by 10%. If the Engineer requests that the field office and labora tory be relocated, the Engineer will pay a relocation fee of $300 per relocation for "Field Office and Laboratory (Type A)" and "Field Office and Laboratory (Type B)" bid items, and $150 per relocation for "Field Office and Laboratory (Type C)" and "Field Office". The relocation fees will be paid for at the amounts shown, as Extra Work, SECTION 104 . 804 - MAINTENANCE AND RESTORATION OF HAUL ROADS
800-11 Section 804
MAINTENANCE AND RESTORATION OF HAUL ROADS 804.1 DESCRIPTION Maintain and restore public roads used as haul roads for construction materials. For the purpose of this specification and when the bid item is included in the Contract Documents, a haul road is any public road in Kansas, ex cluding State highways over which material is hauled for the construction of the project. The most direct route to the nearest state highway that is used for hauling commercial material into or from a commercially established plant site is not designated as part of the haul road. Roads into and from quarries are not designated as part of the haul road. When the bid item is not included in the Contract Documents, any haul road repair is subsidiary to the other items in the Contract Documents. B I D I T E M U N I T S Maintenance and Restoration of Haul Roads (Set Price) Lump Sum 804.2 MATERIALS Provide the type of materials necessary to maintain and restore the haul road to its condition before the hauling begins. The Engineer will accep t the materials used based on visual inspection at the point of usage. 804.3 CONSTRUCTION REQUIREMENTS Provide the Engineer with a written description of th e designated haul roads. The description shall include, materials being delivered, materials hauled to the project site and return routes from the project site. The Engineer will notify the owners of the roads (city and county) of the Contractor’s designations. Allow the Engineer sufficient time to inspect the desi gnated haul roads before they are used. The Engineer, the Contractor and the owner of the roads (at their discre tion) will jointly inspect the designated haul roads before they are used. The Engineer will document any deficiencies or special conditions regarding the existing roads and structures. During the hauling operations, use only designated haul roads. Observe legal weight limits and speed limits. Provide an adequate water supply and apply the water as needed to control dust. Control dust on active haul roads including return routes, in pits and staging areas, and on the project. Perform preventative and repair ma intenance as necessary to minimize the damage to the haul roads. After the hauling operations are concluded, the Engineer, the Contractor and the owner of the roads (at their discretion) will jointly inspect the designated haul roads. The Engineer will review the results of the initial and final inspections, and will consider the impact of other parties that used the haul roads. Upon consideration of all these factors, the Engineer will determine the ex tent of restoration necessary to return the haul roads to their conditions at the time of the initial inspections. Restore the haul roads as directed by the Engineer. 804.4 MEASUREMENT AND PAYMENT When the Maintenance and Restoration of Haul Roads (Set Price) bid item is included in the Contract Documents, and the Contractor uses the designated haul roads, the Engineer will measure maintenance and restoration as a lump sum. This measurement for payment is made regardless of whether or not it is necessary for the Contractor to perform any maintenance or restoration. When the bid item is not included in the Contract Documents, any haul road repair is subsidiary to the other items in the Contract Documents. If the bid item is in the contract and the Contractor does not designate any haul roads, no measurement for payment is made. If the bid item is in the contract and the Contractor designates haul roads but does not use any, no measurement for payment is made. 804 - MAINTENANCE AND RESTORATION OF HAUL ROADS
800-12 If the Contractor uses haul roads (as defined in this specification) other than those designated, payment for
"Maintenance and Restoration of Haul Roads (Set Price)" is forfeited. The Engineer will require that the Contractor restore the undesignated haul roads to their approximate condition before hauling to the project began. The Engineer will determine the exte nt of restoration necessary. Payment for "Maintenance and Restoration of Haul Ro ads (Set Price)" at the c ontract unit price is full compensation for th e specified work.
