Questions & Answers Question 1: Has system been assembled and disassembled?
Answer 1: The system will be partially assembled at the factory to check fit-up.
Question 2: Will any pre-levelling of the slab be required of the Contractor?
Answer 2: No, any levelling of the hutch wall will be accomplished with lead shims (this should be minimal).
Question 3: How deep are the floor penetrations for the door trenches?
Answer 3: 2 inches.
Question 4: Is hammering considered noisy work?
Answer 4: Daily toolbox meetings will occur to discuss the day’s work and any work that includes disruptive noise or vibration will be planned accordingly as to not disrupt sensitive equipment.
Question 5: Floor flashing of lead is not preformed; it is flat, correct?
Answer 5: Yes, floor flashing of lead is not preformed. This is to be bent up by Contractor during installation.
Question 6: Will pre-existing compressed air and water stub outs be removed before installation?
Answer 6: No, those are staying and will deliver utilities to the hutch, but will not interfere with the hutch installation.
Question 7: Will contractor be responsible for electrical?
Answer 7: No, contractor will not be responsible for electrical work; this is BSA’s responsibility. Contractor will only be responsible for temporary lighting.
Question 8: Will lead gaskets come in roll or sheets?
Answer 8: Lead gaskets will come in pre-cut, flat strips, some trimming will be required.
Question 9: What type of fasteners will go into the concrete walls?
Answer 9: Expansion type anchors. All fasteners are provided by BSA.
Question 10: Is the Unistrut welded to the panels or does the Contractor need to fasten it?
Answer 10: The Unistrut pre-welded to the panels. Any Unistrut on concrete walls is installed by the Contractor using hardware by BSA.
Question 11: How does the lead gasket get fastened to the floor?
Answer 11: The lead gets hammered flat to the floor with a wood block to eliminate any gaps between the gasket and the floor. Anchoring the panels to the floor hold the lead gaskets in place.
