AD3.001 Question:
Response:
On drawing M2.03, Note 3 indicates the refrigerant piping is to be temporarily capped in one phase and then completed in a future phase.
Additionally, note 1 states that refrigerant sizes are to be per the manufacturer’s recommendation. However, it is not clear what equipment this piping is serving. Could you please confirm which equipment this piping is serving?
The piping serves BS-4 and VRT-25 thru 32 in the IT department. Refer to drawing M3.01 for continuation of piping.

RESPONSES TO BIDDERS’ QUESTIONS (Continued):
AD3.002 Question:
Response:
See below from addendum #2. Will CCPS hold the “separate prime contract” for the abatement work?
Specification Section 02 41 19, 1.9D. Hazardous Materials:
Asbestos-containing materials are known to be present in the building. A separate prime contract for Asbestos’ Abatement is a component of the Work. Asbestos will be abated in phases in accordance with the project phasing plan found in Division 1 Section “Construction Progress Documentation”.
1. If suspected hazardous materials are encountered that are not identified as part of the Asbestos Abatement Contract, do not disturb; immediately notify Architect and Owner. A report on the presence of hazardous materials is on file for review and use.
Examine report to become aware of locations where hazardous materials are present.
No. Calvert County Public Schools will not hold a separate prime contract for asbestos abatement associated with this Project.
Asbestos-related work identified in the Contract Documents is included in the Work of the bidding Contractor and shall be performed in accordance with Specification Section 02 41 19, Section 02 84 00, and the project phasing plan.
The Contract Documents identify certain asbestos-containing materials as non-friable and permit encapsulation of those materials in lieu of removal, as specified. In particular, asbestos-containing floor tile mastic identified in interior areas can remain in place and be covered, as indicated on the Drawings and specified in Section 02 84 00. Also see Marked Floor Plans located on pages 10-13 of the Hazardous Materials Evaluation (Asbestos and Lead Based Paint) Report, following 02 84 00.
Specification language addressing hazardous materials encountered outside of the identified asbestos abatement scope, referenced in the question applies only to previously unidentified or suspect materials not documented in the Contract Documents. If such materials are encountered, the Contractor shall not disturb the material and shall notify the Architect and Owner in accordance with the specifications.
Bidders are responsible for reviewing the Drawings, hazardous materials report, and all applicable specification sections for complete requirements.
