01010-2

d. Some construction sites are in controlled or restricted areas and will require the Contractor and subcontractors to have the requisite badging and identification to access these project sites. The Contractor shall consider in the contract documents (e.g., the construction cost estimate) the reasonable costs and effects of daily, short delays in accessing the project sites, as required by the restrictive access requirements of by local alert conditions.

1.2 Salvage and Disposal: All salvageable and non-salvageable material obtained by removal of existing material shall be considered as having been included as a factor in the Contractor's bid price.

a. Salvageable material obtained from existing construction may be reused only if so stated elsewhere in the Contract Documents, and then only when the material is approved for reuse by the Contracting Officer.

b. Salvageable material shall remain the property of the Government only when specifically called out in the Contract Documents.

c. Salvageable material not reused or otherwise designated to remain the property of the Government shall become the property of the Contractor and shall be removed and disposed of off base in accordance with the environmental controls specified in this Section.

d. Non-salvageable material: Remove all non-salvageable material from the project site and dispose of it off base, in accordance with the environmental controls specified in this Section.

1.3 Base Outages and Digging Permits (AF Form 103, BCE Work Clearance Request):

a. Utility Outages: Accomplish all work required in connection with utility outages on weekends or off-duty hours, or as directed by the Contracting Officer. The Contractor shall be responsible for all work associated with the utility outages. Notify the Contracting Officer in writing 21 calendar days prior to the desired date for the utility outage.
