SUMMARY OF WORK

PART 1 - GENERAL

1.1 SUMMARY

A. Work for this project consists of the demolition and removal of the Val Verde Guard Station. The structural condition of the building is very poor, so extensive safety measures will be needed for the duration of the project. In addition, the building’s sheet vinyl flooring contains asbestos, therefore proper removal and disposal techniques must be taken by a licensed asbestos removal company. A plan of action, prepared by an asbestos consultant licensed in the State of Colorado, shall be submitted prior to commencement of work. After the asbestos material is removed and the building is demolished, scrape and properly dispose of the top 2 inches (minimum) of topsoil and uniformly rough grade the area to a smooth surface, free from irregularity and surface changes. Seed all areas disturbed by work activities.
