- AMENDMENT 005ADDITIONAL QUESTIONS AND ANSWERS Q. Specification section 13 99 98 does not specify a number of layers required for the shielding. The detail in the drawings shows only one layer of M36 silicon steel on the walls and floor. Please verify that only one layer of shielding material is required. RESPONSE: Number of layers and details per drawing AS-510 Q. Is shielding required on the wall between rooms 1A215 and 1A216? If so, is the floor shielding to run under the wall or up to it? Are we required to shield both sides of the wall or is only one side required? RESPONSE: Yes, shielding is required on the wall between rooms 1A215 and 1A216. Floor shielding to run under the wall as shown on drawing AS-510 -section titled "Attachment of steel to floor and walls". Q. Floor shielding can be installed as detailed in the drawings and specifications, but there will not be the required five (5) year warranty against delamination. This installation method is not standard and the adhesive is not manufactured for the purpose of gluing sheet steel to a concrete floor, and could be a warranty issue. Would this be acceptable or do you have another method? RESPONSE: Warranty to be provided per the specification. Alternate installation methods, which include the cost of all associated items for a complete installation, can be submitted for consideration. Q. 13 99 98 - 3.3- E specifies the wall shielding to be connected to the roof decking above. It describes 2 different details to accomplish this. The latter detail describes terminating the shield on a steel stud frame attached to the roof deck. Since we are not providing the support framing for the shielding, we assume the walls of these rooms run to the decking above and attaching to them is sufficient to satisfy the requirement of the specification. If the top of the wall has a deflection track, please give us a detail for this connection since the shielding can't be connected to the top track or the decking without defeating the deflection joint. RESPONSE: Shielding to come into contact with the top track in order to maintain the continuity of the shielding enclosure with the metal decking above. Actual attachment can occur at the top track if regular track is used, or, at the vertical studs if deflection track is used. Q. Can the low voltage (24 or less) be installed in open plenum cable where accessible such as above ceilings or down walls? The below sections contradict themselves as to all conduit requirements or cable without conduit. RESPONSE: Install all control wiring in conduits, concealed in the walls or above ceilings. Q.Spec Section 23 09 23 2.14 L.2.c. -Page 54- states if need additional power panel boards are by HVAC. I do not think we will need any but if would need the power spare breakers from breaker panel must be available to us RESPONSE: The bid documents currently indicate multiple circuits for use by the controls contractor. We have estimated the quantity of circuits based on our experience with other projects but every control provider has different requirements so if they need additional circuits they must be included in the bidder's project cost. The current provisions include: Ground Floor - Existing Panel EQGLB: (4) 20A-1P circuits for Building Controls. This panel also has (15) 20A-1P spare breakers and (9) 1P spaces First Floor - Existing Panel EQ1LB: (4) 20A-1P circuits for Building Controls. This panel also has (15) 20A-1P spare breakers and (13) 1P spaces Second Floor - Existing Panel EQ2LB: (2) 20A-1P circuits for Building Controls. This panel also has (15) 20A-1P spare breakers and (13) 1P spaces If the contractor needs additional circuits they can provide new breakers in the available spaces in these three existing panels. The HVAC contractor is responsible to provide any additional breakers required.
