General

We are requesting to be able to schedule a time where we can perform core samples on the roof areas. Core samples are required so that we can provide an accurate estimate.

General In regard to the lightning protection system demolition and reinstallation, will the electrical contractor be able to re-install the system or will the VA require a certified lighting protection provider to do the re-install? As there are no lightning protection drawings available and the scope and amounts of items related to the system are not quantifiable from the drawings themselves we would likely need to self-perform the re-installation scope of work for bid pricing purposes as there is limited info for our certified vendors to price out.

At completion of project a UL master labeled lightning protection system is required.

General In regard to the lightning protection system, please confirm if the VA will require re-certification of the existing system once re-installed.

Certification that lightning protection has been inspected by a UL representative and has been approved by UL required.
