CONSTRUCTION LAYOUT: This work shall consist of construction staking according to Article 105.09 of the “Standard Specifications for Road and Bridge Construction”, except as modified herein.

The Local Agency will provide adequate reference points to the centerline of survey and benchmarks as shown on the plans and listed herein. All additional control points set by the Local Agency will be identified in the field to the Contractor and all field notes will be kept in the office of the Resident Engineer.

The Contractor shall provide labor, equipment and material to set all additional stakes for the project, which are needed to establish offset stakes, reference points, and all other horizontal or vertical controls, including supplementary benchmarks, necessary to secure a correct layout for the roadway portion of the work.

The Contractor shall be responsible for having the finished work conform to the lines, grades, elevations and dimensions called for on the plans. Inspection or checking of the Contractor’s layout by the Engineer and the acceptance of all or any part of it shall not relieve the Contractor of his/her responsibility to secure the proper dimensions, grades and elevations of the several parts of the work. The Contractor shall exercise care in the preservation of stakes and benchmarks and shall have them reset at his/her expense when any are disturbed.

Responsibility of the Local Agency

• Centerline will be marked with mag nails and painted on the existing pavement surface one time only.

• Control points referenced to the survey centerline will be provided at intervals not exceeding 1000 ft.

• Benchmarks will be established along the project outside of the construction limits lines not exceeding 1000 ft. intervals horizontally and 20 ft. vertically.

• Critical points for proposed curb ramps and corner radii will be staked to establish proper grades.

• Main line concrete curb and gutter will be staked at 50 ft. intervals, including high/low points and points of horizontal inflection for curvature.

• Proposed profile grade line will be established off the completed concrete curb and gutter and will be based on the proposed widths and slopes of the new pavement structure.

• Additional interior pavement stakes or curb and gutter stakes with intervals less than stated above will not be provided. If these locations are needed the contractor will be responsible for setting additional stakes by interpolating between the provided stakes.

• Proposed right-of-way and temporary construction easements limits will be staked at break points and on tangent at intervals not to exceed 100 ft.

• Drainage structures will be staked by the Local Agency to establish proposed horizontal and vertical locations for the drainage system.

• The Local Agency will accept responsibility for the accuracy of the initial control points and stakes as provided herein. The Contractor shall assume full

Monroe County responsibility for all dimensions and measurements taken or derived by the Contractor from control points or stakes set by the Local Agency. It is not the responsibility of the Local Agency, except as provided herein, to check the correctness of the Contractor’s stakes.

• The Local Agency will set all stakes that are the responsibility of the Local Agency one time only. If any additional staking or re-staking is required, the Contractor shall pay the Local Agency for all costs incurred at an hourly rate of $150. Payment for additional staking shall be made directly to the City.

Responsibility of the Contractor

• The Contractor shall provide written requests for all staking to be provided by the Local Agency. A minimum 48-hour advance notice will be required prior to the commencement of all requested staking activities.

• The Contractor shall establish from the given survey points and benchmarks, all additional control points necessary to construct the individual project elements. It is the Contractor’s responsibility to tie in centerline control points in order to preserve them during construction operations.

• The Contractor shall provide all additional staking required to assure completion of the work in substantial conformance with the plans.

• The Contractor shall be responsible for re-establishing all stakes removed or disturbed by construction operations.

• All work shall be according to normally accepted surveying practices. Field notes shall be kept in standard survey field notebooks and those books shall become the property of the Local Agency at the completion of the project. All notes shall be neat, orderly, and in accepted form.

This work will not be measured separately for payment. The cost incurred by the Contractor in complying with the requirement shall be considered as included in the contractor unit prices bid for the various items of work.

COMPLETION DATE PLUS WORKING DAYS: The Contractor shall complete substantial work by April 30, 2027. Substantial work shall consist of all items required to open the road to thru traffic. After the completion date, an additional 10 working days will be allowed to complete seeding, punch list, and final clean up.

Effective: January 1, 2022

Replace the first five paragraphs of Article 1030.06 of the Standard Specifications with the following:

“ 1030.06 Quality Management Program. The Quality Management Program (QMP) will be Quality Control / Quality Assurance (QC/QA) according to the following.”

Delete Article 1030.06(d)(1) of the Standard Specifications.

Revise Article 1030.09(g)(3) of the Standard Specifications to read:

“ (3) If core testing is the density verification method, the Contractor shall provide personnel and equipment to collect density verification cores for the Engineer. Core locations will be determined by the Engineer following the document “Hot-Mix Asphalt QC/QA Procedure for Determining Random Density Locations” at density verification intervals defined in Article 1030.09(b). After the Engineer identifies a density verification location and prior to opening to traffic, the Contractor shall cut a 4 in. (100 mm) diameter core. With the approval of the Engineer, the cores may be cut at a later time.”

Revise Article 1030.09(h)(2) of the Standard Specifications to read:

“ (2) After final rolling and prior to paving subsequent lifts, the Engineer will identify the random density verification test locations. Cores or nuclear density gauge testing will be used for density verification. The method used for density verification will be as selected below.

Density Verification Method Cores

Nuclear Density Gauge (Correlated when paving ≥ 3,000 tons per mixture)

Density verification test locations will be determined according to the document “Hot- Mix Asphalt QC/QA Procedure for Determining Random Density Locations”. The density testing interval for paving wider than or equal to 3 ft (1 m) will be 0.5 miles (800

m) for lift thicknesses of 3 in. (75 mm) or less and 0.2 miles (320 m) for lift thicknesses greater than 3 in. (75 mm). The density testing interval for paving less than 3 ft (1 m) wide will be 1 mile (1,600 m). If a day’s paving will be less than the prescribed density testing interval, the length of the day’s paving will be the interval for that day. The density testing interval for mixtures used for patching will be 50 patches with a minimum of one test per mixture per project.

If core testing is the density verification method, the Engineer will witness the Contractor coring, and secure and take possession of all density samples at the x
