1.04 PROJECT SURVEY REQUIREMENTS

A. Establish a minimum of two permanent bench marks on site, referenced to data

established by survey control points.

1. Record locations, with horizontal and vertical data, on project record documents.2. Contractor shall base all measurements of the construction, both horizontal and

vertical from established bench marks. All work shall agree with these established

lines and levels. Contractor shall verify all measurements at site, and check the

correctness of same as related to the work. Should the Contractor discover any

discrepancy between actual measurements and those indicated which prevent

following good practice of the intent of the drawings and specifications, he shall

notify the GOTEVT and shall not proceed with his work until he has received

instructions from the GOTEVT.

1.05 LAYOUT AND SURVEY

A. Points, Lines, Levels and Locations for Building:

1. Existing grades, points, lines, and site conditions shown on Drawings were takenfrom civil survey information established by persons engaged directly by Engineer before

proceeding with layout work. The final positioning of the works will be approved by the Engineer.

2. Employ a surveyor licensed to practice at the place of building to:layout building on site.:establish permanent bench mark, or markers as widely

separated as possible

:verify elevations of floor levels as construction proceeds, and relate to bench mark

datum.:verify that present, or known future restrictions, are not violated by construction

on the site or lines of traverse to all public utilities.

:correlate geodetic elevation of bench mark datum with elevations in use by public

utilities adjacent to the works.

:verify accuracy of site dimensions shown on Drawings.

:provide a survey to verify location of building on site.

B. Work Adjacent to Public Property:

Pay all charges made by public bodies for the rental of public property, and for work

required on public property.

1.06 DRAINAGE

A. Ensure that positive drainage is provided to roof, floor, and site drains and catch

basins, as set in their final positions. Provide constant slopes for drained surfaces to

drains and drainage courses.

B. Ensure that allowable construction tolerances and structural tolerances do not permit

pounding of water.
