Infill windows with gyp on adjacent sides. ICRA requirements to be maintained and coordinated with VA COR.

Mechanical Technical Questions

32. Due to underground utilities around and possibly over the existing fuel tank, hydro excavation will be the safest way of tank removal. Will there be any disposal requirements for the removed material?

RESPONSE:

Please refer to Civil Spec Section 312011 Earthwork for excavation and backfill requirements. If the removed material is still considered “suitable” it could be reused, if it is deemed “unsuitable” after removal, disposal is subject to the contractor, specifications, and environmental considerations/regulations.

33. Specification 23-10-00 is fuel related information. It calls out for a concrete anchor will there be a detail showing the concrete pad dimensions, per specified tank?

RESPONSE:

Please refer to Civil plans and specifications for concrete anchors and pad dimensions.

34. If the ground around the existing fuel tank is contaminated what is the contractors responsibility and will a modification to the contract be issued? Spec 31-20-11 refers to unsuitable material, would fuel contamination fall under this specification?

RESPONSE:

Please refer Spec Section 312011-1.2.A.1 Unsuitable Materials.

35. Will the grease pipe have heat trace? Current elevations show just over 1/8 per foot of fall with a total distance of 183’ +/-

RESPONSE:

Due to space and placement constraints, that is the closest and most suitable place for the interceptor. Neither ASME A112.14.6 nor the manufacturer’s instructions indicate a maximum length/fall for this system. So, while it was not included in the design drawings, the inclusion of heat trace piping (through an ASI or addendum) to the grease pipe would make the likelihood of grease build-up happening during a longer run less likely, therefore decreasing the risk of backup or the need for more frequent maintenance and cleaning of pipe. Not required from all that could be referenced and found, but also used as an industry practice to mitigate issues. If heat tracing is deemed most effective for this system by the contractor and the owner, coordination with the electrical engineer and contractor will need to occur.

36. Per PG 101 phase 2 ground floor, hose reels are indicated as (typical) detail P-401 shows 4 hose reels. Are these considered “medical air” hose reels and will they be specified?

RESPONSE:

These are for dental air, so they would be considered “medical air.” These hose reels should be owner/contractor selected and provided as they are specific to the internal equipment needs of the space.

37. Per MH 101 ground floor mechanical PH 1- shows 4 temporary duct (34x14, 22x12, 22x12, and ?) will these be installed during normal working hours? During the walk, it did not appear space was available for the additional duct. would flex duct be acceptable in certain areas?

RESPONSE:

Temporary flex duct can be acceptable if intent is relayed and agreed upon by the owner and Engineer in advance of installation, for confirmation of sizing and airflow needs. Timing of installation shall be coordinated with the owner and stakeholders of the spaces it will affect.

38. Are new openings in the existing building required for the temporary duct or will they be allowed to exit a window within the cafeteria?

RESPONSE:

Coordinate with VA for preference of that means/method.

39. Will more information be provided for the relocation of the dust collection unit? RESPONSE:

Coordinate with owner for additional information on dust collection equipment and locations.

40. A note is provided for the fire dampers when penetrating the floor but this note is not represented at all duct penetrations. Will all fire damper, smoke dampers, fire & smoke dampers be listed on a schedule page and located?

RESPONSE:

Floor penetrations are to be provided with fire dampers and the note is to be typical for all floor locations. Fire dampers, Smoke damper and combination fire/smoke dampers are not scheduled but are located on the floor plans.

41. Where the underground chilled water connects to the existing, does it pass under the existing steam trench?

RESPONSE:

The buried chilled water is routed above the steam trench per site utility drawings. Request for the latest site utility drawings from the VA as they are updated.

42. What is expected for the “direct buried” chilled water piping? RESPONSE:

Piping to be directly buried in the ground with proper packing and jacketing to protect pipe from movements and temperatures.

43. During the transition from phase one and phase two, how many days are projected for the completion of the grease line in phase 2 and setting the new grease trap and lift station? During this transition the kitchen will not be operational. RESPONSE:

Construction durations at the behest of the contractor schedules, methods, and owner coordination.

44. In the existing court yard there is a condensate tank vent along the south wall at 4’ above ground. Where should this be re-routed? At this location there is also a domestic water outlet, will this outlet demo?

RESPONSE:

Demo domestic water outlet back to nearest main to remain. Please provide more info on the condensate tank vent or cate to the nearest acceptable location if not indicated on drawings.

45. Per MP101 note 58, will a chase be provided for the existing chilled water lines on ground floor? The current layout indicates the chilled water lines and the freezer (025D) wall occupying the same space. Other floor has chase. RESPONSE:

Existing to remain, lines appear to stop above the freezer on the ground floor. Contractor to verify. Space to the north of the freezer is a mechanical chase between buildings. Lines may reside in this space as well.

46. Per MHD101 note D15 (demolish existing exhaust fan and associated accessories) from the prints it is unclear what this serves. Will a temporary exhaust system need to be provided during phase one construction?

RESPONSE:

Appears to be the pump room. Should be okay as is during construction, confirm with VA. Small temporary system would also be appropriate to keep heat and fumes from building in pump room if phases are extended. Plan to attach new exhaust system and quickly as possible in the transition.

47. Just to the north of the above mentioned exhaust fan there is a 12x12 wall louver that was noticed during the walk. Will this item be identified and instructions provided?

RESPONSE:

Not part of scope area. Appears to be on other side of stairwell, possibly for ventilation.
