E. All employees of general contractor and subcontr actors shall comply with VA security management program and obtain perm ission of the VA police, be identified by project and employer, and restricted from unauthorized access.

01 00 00 -2

F. Existing Conditions/Demolition

1. Currently there are five dual-fuel steam boilers in the boiler plant of Building 112. The two English boilers that were installed in 2008 and the existing DA tank, feed water pumps and surg e tanks will remain. The three existing Nebraska boilers and the ir associated flues and economizers shall be removed in their ent irety; however, the concrete pads for the boilers will remain and b e reused for the new boilers. The existing 20 gpm Wigens reverse osmosis system s hall be removed and replaced with a new system that has a large enough capacity to handle the entire steam plant.

2. The existing 10” steam header will remain.

G. Asbestos Abatement

1. A visual inspection of the building materials lo cated within the limits of the renovation was completed. In the area s of construction there will be selected asbestos abatement. The area s to be abated will primarily include the piping insulation at the associated hydronic piping systems of the 3 boilers being repl aced, along with the asbestos abatement of the insulation on the boi lers. An asbestos survey report is included as Attachment B in specifications

Volume 2.

H. Architectural

1. The following modifications are included in the project scope:

a. Improved catwalk around the newly installed DA a nd Surge tanks

b. New upper level access doors to the catwalk leve l

c. New lab casework

d. New large rollup door at existing loading dock

e. Minor modifications to the roof to accommodate t he economizers

f. New electrical closet under DA tank

I. HVAC System Description

01 00 00 -3

1. The existing Nebraska boilers that are being rep laced have a capacity to provide steam flow rate of 30,000 lb/hr . The new boilers will increase the capacity of the steam boiler plan t by an additional total of 60,000 lbs/hr steam flow rate ( an additional

20,000 lb/hr per boiler). They will provide 150 psi steam pressure and have the capability to turn down to 25% of its maximum capacity at an efficiency of 84%.

2. Burner piping shall be stainless steel and the b oiler safety device switches were designed based on Mercoid.

3. New boilers shall be placed and anchored to exis ting concrete equipment pads.

4. The existing 6” steam supply mains from each exi sting boiler shall be upsized to 8” to accommodate the additional stea m capacity.

5. A new 2200 gallon DA tank and 2200 gallon Surge tank shall be mounted above at the mezzanine, with their associat ed pumps being mounted on the first floor level below. This equipm ent shall be added to give redundancy to the existing system and piped in such a way so that the operation of the feed water pumps a nd tanks can be alternated from one system to another.

6. The existing air compressors located in the base ment shall be replaced with new air compressors located in the ba sement and shall be replaced with new air compressors. All the exist ing air compressor piping and tanks shall be re-used and th e new compressors shall be installed on the existing concrete equipme nt pads.

7. An existing 1 ½” condensate return main that run s from the steam header around the plant shall be removed and connec ted into an existing 1 ½” return line located in the trench at the boiler room floor level.

8. A new Reverse Osmosis (RO) System shall be insta lled in place of existing 20 gpm Wigens RO System with new mainfolds , control panel and pump with VFD. The new system will tie into the existing piping and shall be used on an alternating basis with the other 40 gpm RO system.

01 00 00 -4

89. The natural gas pressure entering the building is at 10 psi. The new boilers require 20 psi gas pressure to operate. Therefore new gas meter/regulator set will need to be installed t o provide service for the three new boilers. The new gas meter/regula tor will connect to the existing 12”, 100 psi gas main located on th e south side of

Building 112 and shall be sized to reduce the press ure from 100 psi down to the required 20 psi. Once the pressure is r educed the existing 6” gas main that feeds the boilers shall b e connected to this new meter/regulator set and be re-used for the new boilers.

J. Controls

a. Replacing (3) existing Nebraska water tube steam boilers and all associated pumps and control panels.

b. Provide power to new boiler water tube steam boi lers and associated feed water pumps and control panels.

c. Replacing existing compressor located in basemen t.

d. Provide Power to new compressor.

e. Provide Power to upgrade 40 gpm Wigens Reverse O smosis System.

L. Existing Conditions/Demolition – Mechanical

1. Currently the existing air compressors AC-1 and AC-2 are feeding out of the existing 480/277V, 3 phase, 4W MCC (East). P ower to these 2 existing compressors shall be removed.

2. Currently existing Forced Air FD-1, FD-2 and FD- 3 AC-1 and AC-2 are feeding out of existing 480/277V, 3 phase, 4W MCC ( West). Power to these 3 existing Forced draft fans shall be removed .

01 00 00 -5
