The contractor will only be required to have one Site Supervisor and one Quality Control Manager for all three projects. The Quality Control Manager may serve as the Site Safety Health Officer if this individual meets all necessary requirements within the specifications, including (01 45 00.00 10 Section 3.4.4) completion of the Construction Quality Management (CQM) for Contractors course.

2 Please advise the current building wall and roof panel manufacturer and color so a proper match can be made for tie-in.

PEMB Roof Color: 872D111 Duranar FC Ultra Cool Gray Tweed PEMB Wall Color: 872R136 Duranar FC Ultra Cool Terras Cotta

Each Building had a different Building Manufacturer:

Building 20470 (Building 1) – American Buildings Building 20471 (Building 2) – VP Buildings

3 What is the existing fire alarm system in the building?

The existing Fire Alarm System is Siemans. This system is compatible and will accept compatible inputs.

Please confirm for bidding purposes that the depicted pre-engineered metal building framing is for general intent only, and does not dictate the final stamped PEMB design that is required for this project?

The Contractor shall follow the Contract Documents for design intent of the pre-engineered metal building framing, including the geometry and framing locations.

We request an extension a minimum of 2 weeks from the date of receival of all RFI answers, in order to properly coordinate with interested vendors, subcontractors, and designers. Noted

Reference drawing A-503. A vapor barrier is shown within the roof section just below the insulation, and a separate continuous air barrier is shown on the underside of the PEMB purlins. Having two distinct air/vapor barriers is not best practice, and will trap moisture between these barriers. Please confirm that only one air/vapor barrier should be installed?

Please provide the continuous air barrier shown below the batt insulation only. The vapor barrier shown above the metal deck may be eliminated

Drawing A-601 is titled “Partition, Door and Finish Schedules”. There is no room finish schedule included in the RFP plans or specs detailing the desired floor, wall, and ceiling finishes in this project. Please provide an edited room finish schedule for this project.

Please refer to specification section 09 06 00 for finish material colors. Refer to drawings for finish materials

Please clarify the commissioning requirements for this project? There is no Division 01 or Division 23 commissioning specification included for this project. Is commissioning required? If it is required, please provide the corresponding edited specification for use.

Commissioning is required.

Commissioning Spec 01 91 00 will be provided.

Drawing S-101 Pier Schedule indicates that Pier P1 is 2’ x 2’ x 16” thick. All piers on S-101 are tagged as P1. Top of footings is denoted as 5’-0” below the top of slab on S-502. Piers as a result will be much higher than 16”. Please confirm that pier heights should be based upon the foundation details on S-502, and not the 16” thickness as shown on the S-101 Pier Schedule?

The pier callout and schedule will be updated to reflect the correct pier depth.

Drawing S-101 depicts a foundation wall and wall footings inside the building. Please confirm the purpose of this foundation wall and footing, and please clarify if this foundation may be eliminated if not needed?

The interior foundation is a lateral tie that is required between the footings. An additional detail will be provided to convey geometry and reinforcing requirements.

Is a lightning protection system required for the new addition as part of this project? There does not appear to be any requirement for a lightning protection system on the drawings, or included in the specs.

A requirement for lightning protection was not determined during design and therefore not included in the documents.

Sheet G-002 references the MGCS shelter in Civil note 11 and references a coiling door with fusible link in Fire protection note 1. These appear to be carry-over from a separate project. Please confirm. Confirmed

S-101 foundation layout appears to show the PROPOSED building in the expected orientation using the doors for reference but the EXISTING building appears to be incorrect. Please advise

Existing building layout will be modified to reflect the correct layout

S-101 shows foundation geometry running E-W between column lines A & C at column line 2 and N-S between 1 & 3 at line B. Please provide section details to explain how these tie into the slab, and what purpose they have.

The interior foundation is a lateral tie that is required between the footings. An additional detail will be provided to convey geometry and reinforcing requirements.

On the site visit there were wall louvers that appear to be in spaces that will have walls built over them. Please provide all pertinent mechanical and architectural details for how these should be addressed.

Existing wall louvers are to be abandoned and wall patched unless shown as part of the new mechanical design

Hydronic heating as shown in details 1 & 6 on M-401 do not appear feasible. Tubing placed below 10” of concrete isn’t likely to heat the slab regardless of EWT, GPM, tubing dia, loop spacing or loop length. If radiant heating is to be incorporated into the design please advise who will be responsible for the design of the system, and design of the installation.

Tubing shall be placed just below the top mat of refinforcing.

Insulation shall be below the slab. Radiant heat design including loops lengths, sizes, flow rates, zones, etc shall be by a radiant heat manufacturer.

Reference A101 at column line D;5.1 shows Wall Type A Shaftwall bypassing column and terminating at exterior wall type C. Enlarged detail 1/A502 shows different column line J.1;5.1. Also shows Shaftwall terminating at beam with unbalanced wall box out on new constructions side.

Please advise which detail is correct for Shaftwall termination at column line D;5.1? Please follow 1/A502

Reference A101 at column line F.1,5.1 shows Wall Type A Shaftwall bypassing column and terminating at exterior wall type D. Enlarged detail 3/A502 shows different column lines K;A5.1. Also shows Shaftwall terminating at beam with unbalanced wall box out on new constructions side, and an adjacent door. Please advise which detail is correct? Please follow 3/A502

Reference building section 2/A301 at column line D notes GWB terminates 1’aff. Wall section 3/A501 (column line J.2), 4/A501 (column line K) base detail shows GWB to finished floor. Please advise which is correct? GWB to extend from floor to 1'-0" above finished ceiling

Reference wall section 3/A301, and base detail 4/A503 calls for Abuse Resistant GWB. Please confirm AR GWB is required at this location? Any other locations? to what Height? Also note question #3 building section 2/A301 calls for GWB to terminate at 1’aff

GWB to extend from floor to 1'-0" above finished ceiling.

Abused resistant GWB is not required in this facility

Reference building section 2/A301 at column line D notes GWB terminates 1’ above ceiling. Wall section 3/A501 (column line J.2), 3/A501 (column line K) head detail shows GWB to roof beam. Partition schedule calls for 1’ above ceiling. Please advise which is correct?

Only fire rated partitions are to be continuous to structure. All other GWB assemblies may terminate at 1 ft over the ceiling

Reference Partition Schedule on A101. Wall Type D2 is to terminate at 1’aff. Building Section 2/A301 shows furred wall extending to roof deck.

Please confirm framing from slab to roof deck, and GWB from 1’ above finished floor to roof deck?

Only fire rated partitions are to be continuous to structure. All other GWB assemblies may terminate at 1 ft over the ceiling

Reference door details on A601 show batt insulation, partition schedule does not. Please confirm no batt insulation required per partitions schedule? Insulation is only required at exterior doors

Reference A102 RCP and all ACT at 10’aff, building section 1/A301 at column line 5.1 appears to show horizontal Shaftwall at 7’-6” aff with ACT above. Please clarify what is required?

No ACT is intended within the column enclousures or the shaft wall enlosure

Ref. A101 Key Note #2 “provide ½” Emseal or Equal” should emseal be fire rated and if so please provide fire rating requirement? Per floor plan emseal appear to be at two locations only at end of Type A Shaftwall. Reference 2/A502 which shows and additional wall left of the door that does not correspond with floor plan. Please clarify which is correct

Provide fire rated expansion seal at keynote 2. A-101 shows the correct A201 is misleading
