- 105 - SECTION 114 -- CONSTRUCTION STAKING
114.01 Description
1.Department and Cont ractor Responsibilities: Each project will have the construction staking done by either the Contractor or the Department. When the pay item "Construction Staking" is shown in the bid proposal Schedule of Items and in the contract, then the Contractor shall accomplish the requ irements in Paragraph 3. of this Subsection. When the Department has t he responsibility to accomplish the construction staking shown in Paragraph 2. of this Subsection, then the pay item "Construction Staking" will not be shown in the contract or the Schedule of Items.
2.Department provided construc tion stakes, lines, and grades shall include:
a.The Engineer will furnish and set construction stakes or benchmarks establishing lines and grades and will furnish the Contractor with all necessary information relating to them. For bridges, the Contractor may require the Engineer to furnish stakes determining the centerlines of all substructure units, together with stakes determining the angles of the wings or retaining walls.
b.The Contractor shall furnis h, free of charge, all additional stakes, templates, and other materials necessary for marking and maintaining all reference points and lines. The Contractor shall construct the work in accordance with the Engineer's stakes and marks, making use of them before they are disturbed.
c.The Contractor shall be responsible for the preservation of all stakes and marks. The cost of replac ing any stakes or marks destroyed or disturbed by the Contractor shall be charged against, and deducted from, the payment for the work at the rate of $125 per hour for each hour of Department time spent replacing the C ontractor disturbed reference points.
d.The Department will not be responsible for delays due to lack of stakes unless the Contractor, when moving onto the work, has given one week's notice that such stakes are needed. Thereafter, 48 hour notice is required.
3.Contractor provided constr uction stakes, lines, and grades:
a.The contract and the bid pro posal Schedule of Items will show the pay item "Construction Staking" when the Contractor is responsible for staking requirements.
b.Contractor Constructi on Staking shall consist of:
1.Establishing or reest ablishing the project centerline.
2.Referencing or re-referencing all necessary control points.
3.Running a circuit of bench levels to check or reestablish plan benchmarks.
4.Setting other benchmarks as needed.
5.Staking right-of-way or restaking right-of-way where needed if it has been previously staked and performing all construction layout and reference staking nece ssary for the proper control and satisfactory completion of all structur es, grading, paving, drainage, and all
114.01 Construction Staking
- 106 - other appurtenances required for the completion of the construction work and acceptance of the project.
6.Provide station lath for concrete paving (100 feet interval) and asphalt paving (200 feet interval) projects.
7.Providing flagging and signage for traffic control. c. Construction Requirements:
1.(i) The construction staking shall be done by personnel who are trained and experienced in construction layout and staking of the type and kind required in the contract. (ii) If the Contractor subcontracts the "Construction Staking" the Subcontractor shall not be the Preliminary Engineering (PE) or Construction Engineering (CE) Consultant performing or having already performed services on the project. The Subcontractor will not be allowed to perform any additional PE or CE services on the project. (iii) All right-of-way monuments and lines shall be established by a registered Land Surv eyor employed by the Contractor. (iv) It is recommended that the crew chief be NICET Certified Level III or a registered Land Surveyor.
v.It is recommended that 50% of the survey crew be NICET Certified Level II.
2.All stakes, references, lines, grades, and batter boards which may be required for the construction operations shall be furnished, set, and properly referenced by the Contractor in a manner consistent with standard engineering practices and in accordance with the Department's Construction Manual or alternate procedures approved by the Engineer. The Contractor shall be solely and completely responsible for the accuracy of the line and grade of all features of the work. Any errors or apparent discrepancies found in previous surveys, plans, specifications, or special provisions shall be immediately called to the attention of the Engineer by the Contractor for correction or interpreta tion before proceeding with the work.
3.Field notes shall be kept in standard, bound field notebooks or in a Department approved computer file. The data shall be clear, orderly, and neat; consistent with standard engineering practices; and in accordance with the Department's notebook procedures. The Contractor shall provide the notebooks, which beco me the property of the Department upon completion of the project. The field notebooks shall be subject to inspection by the Engineer at any time.
4.The Contractor shall be responsible for the placement and preservation of adequate ties and refere nces to all control points, whether established by him/her or found on the project, necessary for the accurate reestablishment of all base lines or ce nterlines shown in the contract. All land ties (i.e., section corners, fracti onal section corners, etc.) that may be lost or destroyed during construction shall be carefully referenced and replaced by a licensed Nebraska Land Surveyor in accordance with the Department’s Construction Manual . A copy of the completed survey and references to the corner or accessory shall be filed with the State Surveyor and with the County Surveyor for the county or counties in which the survey corner exists within 30 days of the date the activity is completed. Construction Staking 114.03 - 107 - (5) On road projects, the circuit of bench levels to check the plan benchmarks shall be run the full le ngth of the project. At bridge sites, the circuit shall include four benchmarks; if possible, two on each end of the structure.
6.The Engineer will make all necessary final checks, measurements, and surveys that invo lve the determination of final pay quantities. He/she may check the accu racy and control of the work, as established by the Contractor 's construction staking, at any time as the work progresses. These checks made by the Engineer in no way relieve the Contractor of his/her responsibility for the accuracy of the engineering layout.
7.The Contractor shall correct any deficient staking or construction work which resulted from inaccuracies in the staking operations or from the Contractor's failure to re port inaccuracies in the contract or survey data furnished by the Department.
8.Following a written request by the Contractor, the Engineer may approve the start of constr uction staking operations before the tentative or anticipated beginning date.
114.02 Method of Measurement
1.Construction staking and surveying will be measured as a lump sum for all surveying and staking requirements.
