Questions and Answers for CSC‐20013; Site Wide Gutter & Roof Repair

1. Plan Page G‐0002 General Note 2 makes the statement that contractor is to field verify the exact extent of the work prior to bidding, however during the site visit, Government Personnel did not want us up on the roofs. Each additional plan page has details of what work needs to be done on each roof. Are we to assume that the work shown on these pages is the extent of the work?

The plans clearly delineate the work required, however should additional work be discovered during the preconstruction walkthrough on each roof, we should be permitted to address those additional areas of work under the differing site condition clause.

Yes, any additional work discovered after contract award may be subject to the differing site conditions clause. However, it is the Government’s position that the extent of the work is shown on the drawings. Contractor claims for differing site conditions would be limited to work above and beyond what is shown on the drawings, so contractor proposals should be inclusive of the effort to perform all work as shown.
