LAYOUT OF WORK AND SURVEYS

PART 1 - GENERAL

SUMMARY

A. Section includes general requirements for survey work to be performed by the Contractor for layout of work features, for performance of work, and for field measurements of work quantities for payment purposes.

B. Before commencing any surveys, the Contractor shall give the County/Engineer two working days' written notice in advance so that the County/Engineer may witness such work.

RELATED SECTION

A. Section 012000 – Measurement and Payment

DESCRIPTION

A. Reference Points: The reference points to be provided by the County/Engineer will include referenced monuments, survey control line(s), and elevation benchmarks in the vicinity of the project. If displaced by the Contractor, replacement of these reference points will be at the expense of the Contractor.

All other necessary reference points shall be established by the Contractor.

B. The Contractor shall furnish all necessary detail surveys including all lines, grades, and appropriate surveys as specified. Contractor shall stake out the line they intend to install the water line and electrical cable. Provide elevation profile of the final water line with survey points every 100’. Provide final grade survey points on existing disturbance area.

C. The County/Engineer reserves the right to perform any desired checking and correction of the Contractor's surveys, but this shall not relieve the Contractor of the responsibility for adequate performance of the work. The County/Engineer will complete any checking within two working days of the Contractor's completed survey.
