TECHNICAL QUESTIONS – PART 2 AND VA RESPONSE TRACKING SHEET

ITEM

NO. QUESTION GOVERNMENT RESPONSE

1. The light fixture schedule on E602 does not seem to match up to the actual fixtures shown on the floor plans (EL-100 and EL-101)

Some examples –

Fixture D2A, D2B Shown on floor plan EL100-N But not listed on fixture schedule on E602

Fixture F3A, F3B, F3C Shown on floor plans But only F3 is on fixture schedule

Fixture F3A – On EL100-N this fixture is indicated as a 2x2 lay-in On EL101-N this fixture is indicated as a can light

On EL101-N This plan has some F9 and F10 fixtures shown However, they are not listed on the fixture schedule

An incorrect Lighting Fixture Schedule was issued with the bid documents. We have inserted the correct fixture schedule on plans and will need to reissue the sheet or provide as an attachment the correct Lighting Fixture Schedule. See Joliet CBOC Elect. Add. 2 230726 attached.

2. What is the overall concept for the new site lighting that goes into the existing parking areas?

Obviously, these areas are already paved.

Does the pavement get removed and replaced, or are we supposed to directional bore new conduits under the existing paving ?

Many phases overlap.

54. Does any of the work need to be done outside of normal working hours?

Yes, Phase C5 relating to demolition of the HVAC riser chase is to be performed over the weekend. Contractor should anticipate off-hours (2nd shift) work for the entirety of Phase C5.

55. Is there enough room in the ceiling area for the new ductwork and piping with the existing duct and piping not being removed until everything is running?

The new heating water piping may be able to be installed with existing ductwork and steam piping in place. We do not anticipate that the majority of the ductwork can be installed without first demolishing the existing ductwork, therefore the phasing plan which is presented in the bid documents.

The ductwork design as presented in the bid documents assumes demo of existing ductwork prior to install of the majority of the new ductwork. Phases C6E and C6W are separated such that the entire area is demolished, replaced, and turned back over in a single period (~7 weeks).

56. There is nothing on the drawing about the Snow melt system for the front entrance, does it use steam and a heat exchanger?

Provide a new shell & tube heat exchanger sized for existing snowmelt area and to match existing steam heat exchanger capacity – approximately 1000 SF of snowmelt in the drive thru area.

57. Are contractors expected to use a temporary boiler or are those connections on the drawings for future MP 101N?

A temporary boiler system is anticipated due to the need to shut down the steam plant and replace it with new heating water boilers, while heating and/or terminal unit reheat is needed year-round. Bidders shall include in their pricing the ability to heat and ventilate the building for the duration of construction schedule which will most likely require a temporary hot water boiler system during steam plant demo and new construction and commissioning. Refer to phasing drawings GC-001 through GC-011

58. On M 601 AHU note #6 says the humidifier manifold is internal to the unit rated at 725 lbs./ph., the humidifier is rated for 300lbs/ph. Is that the correct manifold?

Please confirm.

The steam distribution manifold should be 300 lb/hr to match the steam generating humidifier.
