B. PROJECT TITLE: Repair HVAC – Arnold & Harmon Hall

C. PROJECT LOCATION: 2302 Arnold & 2304 Harmon Hall, USAF Academy, Colorado

2. DESCRIPTION OF PROJECT:

A. PROJECT BACKGROUND: Chilled water that is generated at Harmon Hall is supplied to Harmon Hall, Arnold Hall and Polaris Hall. Cooling towers are located on Arnold Hall roof which is piped vertically and through tunnels to Harmon Hall.

Harmon Hall HVAC system consists of water cooled heat pumps which reject heat to the chilled water system via heat exchangers located in the basement of Harmon Hall. This project will replace the cooling towers located on the roof of Arnold Hall.

The cooling heat exchangers at Harmon Hall will be upgraded to flat-plate type and various piping and controls will be upgraded. A temporary air cooled chiller will be utilized during cooling tower demo and replacement. Hazardous material testing was performed and results are included with project documents.

B. CONSTRUCTION SCOPE: The Contractor shall execute the project as shown in this SOW, Project Drawings, and Specifications. In case of conflicts between documents, the order of precedents will be Contract, SOW, Specifications and then Project Drawings.

3. GENERAL PROVISIONS:

A. GENERAL - The Contractor shall supply all labor, materials, transportation, equipment, and supervision to provide a complete, finished, functional product meeting USAFA Specifications.

9. BIDDING RFI QUESTIONS AND RESPONSES:

A. Listed below is the valves that I think will need to be 120V. I could not find some of them on the drawings except page M-704 and M-706: CV-1, 2, 3, 4, 5, 6A, 6B, 7A, 7B, 9, 10, 13, 14, 15A, 15B, 16A, 16B

1. Answer: Refer to attached control valve schedule for clarification.

B. I don’t see CV-1 or CV-2 from page M-704 on page M-405. These are the Cooling tower isolation valves. Will these valves be located near the CT’s in the Cooling tower well shown on M-405 detail 2?

1. Answer: Refer to sheet M301 for location of CV1 and CV2 in roof well.

C. Page M-704 shows new valves in the condenser water lines on each chiller. CV- 6A, CV-6B, CV-7A, CV-7B. I don’t see these valves on page M-404 in the piping.

Are these new or existing valves? If they are new, they need to have 110V run to them as well.

1. Answer: New valves CV6A/CV6B and CV7A/CV7B provide head pressure control for chillers CH1 and CH2 respectively, and are to be located in mechanical room B012. Refer also to control valve schedule.

D. Reference sheet E-0101, Electrical New work Plan Room B002, indicates that the 600A safety switch for the Temp Chiller is to on the exterior of the build by core drilling thru the wall. During the job walk we were told that this is not allowed. Please identify new location of temporary disconnect and conduit routing.

1. Answer: Refer to item 4.K.1 for clarification.

E. Reference sheet E-104, Electrical Plan Main Level, Keynote 3 states that we are to remove the abandoned disconnect S103 and install a splice box. During the job walk we were told that disconnect S103 is in use. Please clarify.

CONSTRUCTION SOW

Last Updated 22 July 2019

1. Answer: Proceed per keynote #3 even though abandoned disconnect was in the ON position during the bid walk.

F. Sheet E-101 Keyed Notes 4, 5, and 6 require a 600A safety disconnect and feeders for the temporary chiller. Disconnect is shown attached to the exterior wall. Does the government want contractor to core drill through the existing terrazzo surface?

1. Answer: Refer to item 4.K.1 for clarification.

G. Once the temporary chiller is no longer needed what shall the contractor do with the temporary utilities to the chiller?

1. Answer: Temporary chiller connections shall remain for future use.

H. Looking at Sheet H-101, which shows the Hazardous Material Sample plans for Mechanical rooms B001, B002 and B003, are we to assume that all the piping that is hashed will need abatement, or are quantities and pipe sizes available?

Looking at Empirical Environmental Asbestos testing report, there are no quantities given of asbestos to be removed.

1. Answer: Abatement contractor shall be responsible for quantities of abatement. HAZMAT testing is delineated on H101 and H102.

I. If asbestos abatement is necessary in the tunnel between Mechanical room B003 and the other mechanical rooms, will the abatement contractor need to leave access through the tunnel during abatement?

1. Answer: It is likely that tunnel access will not be possible during abatement of chilled water piping in the Harmon Hall tunnel. However, it is the general contractor’s responsibility to coordinate work of all trades.

J. In section 02 08 00, Asbestos Abatement, Section 1.5 Project Conditions, D, it states that storage of removed items or materials on-site will not be permitted. Is an enclosed 40 yard asbestos dumpster going to be allowed on site for the duration of the abatement project?

1. Answer: The noted specification section does not permit storage of abatement materials on site. The contractor will need to remove accumulated materials at the end of each work day.

K. Temp chiller location will require what type of pad.

1. Answer: It would be typical for the temporary chiller to remain on a trailer for easy transport to and from the work site. However, it will be up to the contractor if a temporary offloading or trailer mounted temporary chiller is utilized.

L. What type of piping material will be required for the temp chiller and will these pipes be required to be insulated?

1. Answer: Refer to M602 for Temporary Air-cooled Chiller Schedule and Note #7.

M. Will permits be required for the crane to pick equipment off of the roof?

1. Answer: Refer to M101 for the proposed site staging plan. Refer to General Note #1 for crane coordination requirements.

N. Chiller tie in points are specified?

S. Specification section 01 31 01 – PROJECT MANAGEMENT notes multiple ‘officers’ are to be provided on the project including quality control, environmental and site safety and health. Is it the intent of this solicitation that a separate ‘hat’ be provided for each of these roles? Specification section 01 35 29 – SAFETY and OCCUPATIONAL HEALTH REQUIREMENTS notes the QC person can be the SSHO on this project while 1.6.2.1 seems to indicate the SSHO and the Superintendent may be the same individual. Please clarify.

1. Answer: Refer to 4.K.4 for clarification.

T. Specification section 01 31 01 – PROJECT MANAGEMENT speaks to an ‘installation construction manager’, does this equate to a project superintendent?

U. The Statement of Work for Construction, para 3.K references ‘Builder’. Please clarify

1. Answer: BUILDER is a facility database that the Government will need to update based on this construction project. The Contractor will need to provide forms and photos for inputs as described.

V. FAR 52.236-1 Performance of Work by the Contractor notes that the Contractor shall perform at least twenty-five (25) percent of the total amount of work to be performed but that this amount may be reduced by supplemental agreement, during performance of the work if there is an advantage to the Government. As this may have cost implications, is it possible to establish this ‘reduced’ percentage prior to proposal development?

1. Answer: The clause at FAR 52.236-1 has been removed from the solicitation.
