Project Question Answer

Fire Station Fence

New Fence Alignment / Final Quantity - The SOW requires approximately 300 LF of new fence, while the drawings show the proposed alignment graphically but do not provide dimensional control. Please confirm the exact limits and final linear footage of new fence. Please also confirm whether the Government will stake the new alignment or whether the Contractor is responsible for survey/layout.

The contractor is resposible for the survey/loayout. The final linear footage will be based on the layout done by the contractor. The LF provided by the SOW is an estimate and bidders should price accordingly.

Fire Station Fence

Temporary Perimeter Security - The existing fence provides direct access to the airfield and must remain secured. Please confirm whether the Contractor is required to provide temporary security fencing, temporary gates, barricades, or other perimeter-security measures during demolition and relocation of the existing fence.

Temporary fence is not required if contractor can maintain perimeter during installation of new fence and removal of existing fence. If temporary fence is not installed, the exisiting fence cannot be removed until the new fence has been installed to maintain installation perimeter.

Fire Station Fence

Fence Demolition / Construction Phasing - Please confirm whether the new fence and vehicle gate must be completely installed, accepted, and secured before demolition of the existing perimeter fence begins. If not, please identify the maximum length or duration that the perimeter may be open or unsecured at any one time.

The installation perimeter must be maintained at all times. If temporary fencing is not installed, the new fence and gate must be completely installed, inspected, and secured before demolition of the existing fence and gate.

Fire Station Fence

Fire Station Emergency Access - Please confirm whether continuous emergency-response vehicle access to and from Building 6954 must be maintained throughout construction and identify the minimum clear access width that must remain available during each phase.
