Finishes

138. Can you specify an allowance to carry for floor leveling?

A. The cost for floor leveling is inside the GMP

Elevators

139. The prisoner elevator does not specify if it’s to be a MRL traction type. Please confirm if this is acceptable. There is also an elevator machine space and control space. Please confirm that this elevator is to be true MRL or if the controller is to be in a separate closet.

A. MRL

140. Shall we include elevator maintenance pricing? Will a long-term contract be tied to the new equipment?

A. Elevator maintenance outside Contractor warranty is outside the GMP.

Plumbing

141. Since most of this building is light hazard, would you consider utilizing CPVC piping in those areas? CPVC allows for easier install, decreases install duration, reduces material costs, improves coordination, creates more space (smaller pipe sizes as compared to steel), and has greater longevity. Note - Exposed areas and attic would remain steel pipe.

A. Not allowable per GSA PBS P-100

Sprinkler

142. Due to early development of the Contract Documents, it is difficult to determine the extent of the FP additions and modifications that will be required.

174. Narrative and Drawings state to reuse and relocated existing cooling tower. Can the existing cooling tower accommodate the new cooling loads from the renovation? If not, what should the cooling tower be upsized to?

A. Existing cooling tower has capacity to accommodate new cooling loads, but will need to be relocated to accommodate future connector between wings. Contractor shall include related cost within GMP.

175. What are the heating and cooling loads of the renovated building so chillers and boilers can be selected?

176. Narrative Section 9.0-F.7.a)6) indicates that stairwell and elevator hoistway pressurization systems are to be included, is this correct?

A. No, the building is not classified as a high rise.

177. Narrative Section 10.0-C. includes battery operated sensors for the lavatories, however, the sensor type for the water closets and urinals is not specified. Should the sensors for the water closets and urinals be battery operated as well?

A. Where water closets and urinals are called for in the narrative with sensor flush valves these will be battery operated.

B. 178. Narrative Section 10.0-D.1.a) specifies trap primers for drains susceptible to loss of water seal by evaporation. Please identify which drains need trap primers - i.e.

restrooms, mechanical rooms, etc.

A. As a starting point it may be assumed all restrooms and mechanical rooms with floor drains will require trap primers. Contractor shall include related cost within GMP.

179. AHU-13 is not shown on drawings. Where is this to be located?

A. In the basement. See answer to question 71.

180. Are the Mail Room air requirements to be satisfied by AHU-13 as listed in Narrative or by AHU-4 as shown on drawings?

A. AHU-13, the single line through the mail room to AHU-4 is from the shaft beyond the mail room.

181. Narrative states " The Historical Courtroom on the third floor of the north wing will be retained with only minor modification at windows. Sheet SD103 also indicates that this area does not require any demolition work. However, sheet SD103 indicates that the structural floors, columns and beams are to be demolished. If the structure in this area is to be demolished and rebuilt, how is this Historic courtroom to be retained?

A. The design team revised the approach to the third floor courtroom to maintain the existing concrete pan joist structure and support it by inserting 4 transfer girders. There is one girder on each side of the existing north south beams. Assume the beams will be W24x229 supported on W12x65 columns at each end. These will be set between the beams and carry to the foundations that will be increased in capacity by the addition of micro piles. The east girder will require two columns on the south end to straddle the window in the courtyard. (There will be 5 columns rather than 4 and a short bracket beam between the pair.)

182. Since this is a Concept Design with a Narrative and some Concept drawings, we understand there will be variances between the two documents. Please provide direction on which document we should follow should we discover large discrepancies. Since today is the last day for submitting questions, we will undoubtedly encounter more as we work through this project.

A. The descriptions in the narrative should take precedence.
