Performance Work Statement Northern Appalachian Research Laboratory – Replace North Wet Lab Drain And Isolation Lab Framework I. Overview

The Northern Appalachian Research Laboratory has a need to replace the metal framework for the drains in its north and isolation wet labs II. Background The wet labs at the Northern Appalachian Research Laboratory were constructed in 1978. The top side metal framework is flush with the cast cement floor which supports grating made of aluminum, fiberglass, or steel openings to each trench.

III. Detailed Requirements

b. Remove grate support L-bracket and dispose of debris. Concrete dust must be maintained to an absolute minimum to protect the science being performed in the other areas of the lab.

c. Repair damaged concrete areas using 5,000psi concrete with bonding agent. Any new damage to the concrete due to the metal removal process will be the responsibility of the contractor to repair. See Appendix for details on type and quantity of concrete repairs required.

d. Replace with structure as shown in the Appendix Diagrams. The material shall be alloy-316 stainless steel.

e. Corner joints of L-brackets shall be welded.
