9. Around The Table for Questions/Discussion

Will grooved piping be allowed? The Owner greatly prefers welded pipe

due to past issues with leaks. An alternate will be provided on a revised

bid form to reflect any potential cost savings associated with grooved

piping.

Last day of the 2015/16 school year – June 10 (students), June 13 (staff)

School start date: There is the potential that funding will be available to

allow an early start – August 9 (staff), August 12 (students). The

traditional calendar start dates are – August 23 (staff), August 29

(students).

o Given the uncertainty of the school start date, we have omitted the

liquidated damages deadline for cooling.

o Cooling must be operational whenever school is in session. The

existing units (AHU, Unit Vents, Portable Spot Cool Units, etc.)

may be used as necessary.

o The desired goal is to have the new unit ventilators in the

classroom wing during the summer break. If this is not practical,

the new chilled water piping system may be connected to the

existing chilled water piping system to allow the existing units to

remain in operation.

o New units may be connected to the new chilled water piping

system on a one by one basis.

Contractors shall move classroom furniture as necessary to perform

required tasks. Contractors shall cover furniture with poly and protect it.

Smoke detectors may be removed if school is out for a break provided it is

coordinated with the local AHJ. Detectors may be covered during

contractor working hours and uncovered during school hours.

Bookshelves: The Owner may elect to box and remove books. Contractor

shall coordinate with Owner to identify potential areas of concern. All

items remaining shall be protected with poly.

An alternate will be provided on a revised bid form to reflect a Quick Ship

alternate for mechanical units to expedite delivery.

All Duke Energy rebates shall be collected/retained by the contractor

(lights, chiller, etc.). Rebate amounts should be reflected in your bid

pricing.

Fire Alarm System: The Fire Marshal will require the system to be

recertified. This may happen in areas or sections. As long as the systems

are in proper working order, the AHJ has agreed to testing after hours.

However, if recertification fails during after hours testing, normal work

hour testing only will be required.

Boiler Room Lighting: Provide twelve (12) 2x4 chain suspended industrial

troffers with T8 lamps, 2 tubes/fixture. Arrange in uniform pattern so that

it is coordinated with the new piping and equipment. Remove existing

lighting. Provide a total of four (4) additional troffers (same as above) in

other mechanical rooms as needed.
