DESIGN ALERT ON INCOMPLETE DEMOLITION DRAWINGS
ISSUE:
Incomplete demolition design documents for mechanical and electrical systems.
BACKGROUND:
The ProCATS database shows a number of construction changes and delays caused
by a failure to provide proper demolition instructions for mechanical and electrical
systems.
DISCUSSION:
There are numerous instances where change orders were issued due to incomplete
demolition drawings of mechanical and electrical systems. Preparing complete
demolition drawings is the A/E's responsibility. For instance:
Mechanical drawings on a project showed a number of fans to be removed,
whereas the electrical drawings did not show any demolition work concerning
these fans;
During demolition of lighting fixtures on a project , the ballast of these fixtures
became PCB suspect,. because the ballasts were not labeled as having `NO PCB'.
They had to be disposed of in accordance with current state and federal regulations;
and
On another project the existing equipment was interfering with installation of new
equipment because the A/E failed to show relocation or demolition of existing
equipment.
RECOMMENDATIONS/CONCLUSION:
VA personnel responsible for design projects should remind their A/E, it's important the
A/E shows proper demolition instructions for all equipment after checking in the field.
