REQUIREMENTS

1.5 LAYOUT OF WORK

a. The Contractor will re-establish the baseline and benchmarks at the site of the work, as described in the plan set.:

b. From the baseline and benchmarks described by the Government in the plan set, the Contractor shall complete the layout of the work and shall be responsible for all measurements that may be required for the execution of the work to the location and limit marks prescribed in the specifications or on the contract drawings, subject to such modifications as the Contracting Officer may require to meet changed conditions or as a result of necessary modifications to the contract work.

c. The Contractor shall furnish, at his own expense, such stakes, templates, platforms, equipment, tools and materials, and all labor as may be required in laying out any part of the work. It shall be the responsibility of the Contractor to maintain and preserve all stakes and marks established by the Contracting Officer, if any, until authorized to remove them, and if such marks are destroyed, by the Contractor or through his negligence, prior to their authorized removal, they may be replaced by the Contracting Officer, at his discretion, and the expense of replacement will be deducted from any amounts due or to become due the Contractor.

The Contracting Officer may require that work be suspended at any time when location and limit marks established by the Contractor are not reasonably adequate to permit checking of the work.

d. Quantity Surveys. The Government shall conduct a preparatory meeting with the Contractor prior to the commencement of any work requiring quantity surveys to discuss the requirements and conditions relating to quantity surveys.

1) All surveying, including layout of work and quantity surveys, shall be accomplished by a registered land surveyor licensed in the state in which the work is performed.

(2) For periods that progress payments are requested, to verify the work place, the Contractor shall provide: (a) the before construction survey data and after/or during construction survey data that represents the actual work in-place and to be considered for payment along with the theoretical grades and slope lines provided in the drawings. (b) Along with the survey data, plotted cross-sections and profiles indicating the theoretical grades and slope lines as specified by the contract drawings and the actual grades and slope lines as constructed. (c) quantity computations calculated by the end area method or other approved method indicating the end areas and tabulated volumes per station.

(3) Quantity surveys as used in this clause means a topographical survey accomplished by ground methods with the display output recorded and stored in an electronic field book for further calculations in a computer. The Contractor shall furnish to the Contracting Officer the electronic data in Mircostation compatible files (DGN)and a comma delimited ASCII file (containing as a minimum the Point Number, Northing, Easting, Elevation, and Point Descriptor). Upon completing the survey, or portion thereof, the contractor shall not disturb the ground surface until such time that the Contracting Officer has completed Quality Assurance checks of the contractors' survey data. The Contracting Officer shall disapprove any survey information submitted by the Contractor that lacks sufficient data.

(4) Quantity Survey Method. Unless otherwise authorized by the Contracting Officer, the cross-section method shall be used to obtain the topography.

Cross-sections shall be conducted to obtain the topography of constructed features including, but not limited to: height, width, grades, and slopes of excavation and/or embankments including berms and excavated material embankments. Individual cross-sections will depend upon the terrain but for pre-construction shall not exceed 500' intervals in straight segments and shall not exceed 50' intervals in curves and/or transitions as identified by the Contracting Officer. For post-construction surveys cross-sections shall be taken at the same location as in the pre-construction surveys. The Pre-Construction Survey and the Post-Construction Surveys shall be submitted in Microstation .dgn format.

Observations shall be recorded at all breaks in slopes with a maximum distance of 25' between observations. Cross sections shall be conducted at 90-degrees to the channel and at sufficient width to extend at a minimum of 10 feet beyond the limits of work, further as necessary to delineate the work in place. Annotated cross-sections shall be created and included in DGN format at 1"=10'. The annotated cross-sections shall indicate the Baseline; the theoretical grades and slope lines as specified; and the actual grades and slope lines as constructed. The Contractor shall plot cross sections from the survey data to visually depict the grade and sections obtained. The Contractor shall use this survey data to develop the as-built drawings. During or post-construction survey data shall be provided at the Contracting Officer's request.

e. All Right of Way shall be staked prior to commencement of construction. All Right of Way markers shall remain in place throughout the life of the project and shall be removed prior to final acceptance, as directed by the Contracting Officer.

d. Existing Channel

Temporary traps to catch drift, location, limits, right-of-way agreements between the Contractor and landowners where work is outside the right-of-way shown on the drawings.

e. Survey

The contractor shall conduct a survey of the channel excavation areas after construction to verify that the required channel grades and cross sections have been obtained. A tolerance of 6 inches, vertically, above the theoretical bottom grade will be allowed.

Unless otherwise authorized by the contracting officer, sections consisting of the bottom width, side slopes, and berms shall be taken at intervals as specified in Section 00 80 00.00 11, paragraph LAYOUT OF WORK. The sections shall include the excavated material embankment areas in addition to the bottom width, side slopes, and berms. The contractor shall plot cross sections from the survey data to visually depict the grade and sections obtained. The contractor shall use this survey data to develop the as-built drawings.
