The area behind the B-882 (project building) along the fence that parallels 78th St. North. See attached.

SOW 3.01 states to perform asbestos testing. It also states to comply with the report in regards to removal/abatement/disposal. Please confirm no abatement pricing is required as part of this solicitation. We assume this will be treated as a change order if required, as no

Abatement costs shall be part of the contractors' proposed price. Proposed price shall also include testing to confirm results of the provided test results and preparation of a new report that confirms the info in the report that was provided.

An abatement plan shall be part of the new report.

Warranty:

a. SOW calls for a 20 year manufacturer’s warranty but does not mention a total system warranty. We would like to propose a total systems 30 year warranty with a No Dollar Limit (NDL) solution. Would the government consider this option or should we stick with pricing a 20 year manufacturer’s warranty only?

b. Please clarify if NDL warranty is requested.

c. Please clarify 20 or 30 years warranty is required.

d. Please clarify windspeed warranty (which can be di5erent than design). The current design windspeed is 90 MPH, we recommend matching with a 90 MPH Warranty. Include total system warranty of 20 years with NDL. Design wind speed shall be 90 mph

5 Is it acceptable to cut the existing metal panel up 12’ - 18’’ in order to terminate the new vertical membrane flashing? Yes

Please clarify that if metal decking, mold damage, or damaged parapet are found it will be treated as an unforeseen condition change order. Or would the government like contractors to assume an amount for repairs? If we are to assume an amount, please provide that amount. The mentioned items would have to be treated as a modification/change order

7 Please confirm what the edge material rating needs to be, we believe UFC standards would drive ANSI/SPRI ES-1 metal.

This is a design build; the General Contractor's designer shall determine the design for edge metal rating based on UFC and other applicable requirements

It does not appear an access ladder or hatch is required for the roof based on there is no equipment, please confirm providing access for maintenance is not a requirement in this project. There is no existing ladder or access hatch and this design does not require the installation of a ladder or access hatch

The current performance period is listed at 240 days in SOW and 270 days in solicitation;

however, the design duration will take up 140 of those days. Will the government consider extending the POP or using administrative POP for design? Please clarify POP duration. CE is willing to increase the performance period to 360 days with the concurrence of Contracting

In section 27.0 SUBMITTALS: Please clarify if exact number of copies are needed at each design phase. Most of the time DoDSafe is used and CDs, full size prints, 11x17 etc. are not needed for each design phase. We just want to confirm as to not include unnecessary costs to the government. We recommend getting final copies of the construction set, but each design review phase can cause confusion and unnecessary costs.

For the 35% and 65% submittals, provide 3 CDs only. No hard copies are required. Delete the requirement for a 95% submittal

Are there routing requirements for the new heat trace circuits? Is the contractor able to run through conditioned spaces on the interior or should we assume all surface mounted conduit on the roof?

Conduits may be run on the interior where appropriate. Where conduit is run on the interior, it shall be above ceilings in office spaces, hallways, etc and at ceiling level in the high bay area. Penetrate exterior walls at soffit level and paint to match exposed conduits at the soffit and fasia.
