13. Inquiry: The door hardware schedule in specification section 087100 appears to be for the doors in the renovated areas but excludes the doors in the new addition. Please provide the hardware schedule for these doors. Specification section 08 71 00 can be found in both projects. For the renovation project YTPM 11-0005; see specification section 08 71 00 for the hardware schedule.

21. The new work requires connections to an existing "Edwards" Fire Alarm panel. Is there any information on which company services/installed this account since the system has to be re-certified after the new devices have been installed? Installation was completed approximately 10 years ago with files placed in the archives. Contractor should plan on having subcontractor completing the modifications to also make arrangements to have it recertified as necessary.

22. The specifications call out for a projector to be installed. It does not specify the size of the projector. Please advise. Projector will be provided by user, contractor will need to provide electrical and video cables as well as adequate mounting support. Typical projectors weigh about 5 pounds and are approximately 12” x 4” x 8”.

23. The specifications mention a basis of design for the lockers to be Vidmar Model XW175X and

Vidmar Model XW340X. These models do not exist through searching and consulting with the

Stanley Vidmar Representative. Is there another basis model to go off of or should something equivalent be to the specifications be found? Please advise. Do not include the final X as part of the model number, search for part number XW 0175 and XW 0340 for Stanley Vidmar Custom

Configured cabinet housing,. see spec. section 10 51 13 for other requirements.

24. Usually in vehicle bays such as this, the space from the floor to 4' above the floor is classified as an "explosion-proof" area with wiring methods appropriate to this classification. I do not see anywhere on the electrical drawings or in the electrical specifications which notes that this is an

"explosion-proof" area. Can you verify that this either is or is not an "explosion-proof" area? Our review has determined that the new facility does not need to be an “explosion proof “area. The design calls for a basic garage for vehicle and equipment storage, there is no maintenance, fueling etc. to take place in this facility. If the contractor would like to submit what standard they are using to justify the explosion proof criteria, we can revisit the question.

25. General Note 10 on plan M001 states: The scope of this project includes Testing and Balancing the entire building including the renovated areas.(See note 10 on sheet M101) Plan M101 note 10

States: Re-balance the rest of the building, refer to as built M13 dated 5/16/02 Project No. 99-

0034. Re-balance Air and Hot Water flows. If the entire building is to be re-balanced, will the entire building be re-commissioned? If yes, the existing plans or as-builts should show the mechanical schedules for the equipment not shown on the renovated drawings. This equipment would be the pumps, boilers, chillers and exhaust fans etc. Could you please provide the as-built drawings? All the outlet air flows and VAV reheat hot water flow rates are shown on the bid drawings. As built drawings should be unnecessary for the bid.

26. There isn’t any mention of LEED Certification that could be found on commissioning. Should the commissioning be completed on HVAC only or on LEED Fundamental Commissioning (includes

HVAC, Domestic Hot Water and Lighting Controls). Please advise. Only new equipment installed under these projects are required to be commissioned.

27. The project is composed of the renovation of Bldg 2452 & the new construction of EOD vehicle facility; can the work be performed on both the buildings simultaneously or it will be phased project? If it is a phased project, what will be the timeline expected for completion of each phase? Both projects can be constructed concurrently.

28. Please explain why there is a 420 day performance period? Will there be interruption on each phase upon mobilization? If there will be interruption, please provide details. When the project was first advertised back in 2012, it was anticipated that with the construction award taking place late in the year, a winter shut down period would be necessary. We do not foresee any interruptions for this project and expect construction to be completed in a timely manner.

29. Specifications has requirement for Superintendent. Super can also perform Safety. Can Super perform Safety and QC? Is a separate QC Manager required? In an attempt to help keep overhead costs down and with the size of this project, we can accept a superintendent to also serve as the QC manager.
