specifications, interpretations and technical approvals.
(c) If a VA Master 1600 Series Construction Specification does not
address the specific project requirements or is not available for an
identified system, the A/E is responsible for its development according
to the VA's Master 16000 Series Three Part Format and identified
Operational and Installation Standards. Contact VHA's TCD-194D for
technical assistance and approval in generating official VA
specification numbering of the developed specification for each
project.

project to
complete each system and subsystem design.
(f) All construction drawings containing Telecommunication System
equipment and/or Distribution Plants and Equipment Rooms must be
approved by VHA's TCD-194D before the drawings are considered
acceptable for construction.
