ADDENDUM NUMBER 1 January 27, 2016

WILLIAMSBURG/JAMES CITY COUNTY PUBLIC SCHOOLS Invitation for Bids # 16-8678

Matthew Whaley Elementary School Auditorium HVAC Replacement

ADDENDUM NO. 1 This Addendum provides clarification and answers to questions at Pre-Bid Conference on January 21, 2016 at 4:00 P.M. at Matthew Whaley Elementary School, Pre-Bid Conference Attendance Log and Plan Holders List and includes Revisions and clarification of documents and drawings, bidder questions received by email, modifies, changes, deletes from or additions to the Bid Documents. The above referenced IFB is hereby amended and clarified as follows: The following modifications, additions, or deletions are hereby incorporated into the contract documents. QUESTIONS:

1. Reference General Conditions – 46-A: Paragraph 2 references a hazardous materials survey related to the project. Please provide referenced hazardous materials report.

Response: ECS Mid-Atlantic report dated June 17, 2015 attached. If the Contractor discovers or inadvertently disturbs any material that he knows, should have known or has reason to believe, may contain asbestos that has not been previously identified, was overlooked during the removal, was deemed not to be friable or was encapsulated, the Contractor shall stop Work in the area containing or suspected to contain the asbestos, secure the area, and notify the Owner and the Architect/Engineer immediately by telephone or in person with written notice as soon as possible. The Owner will have the suspect material sampled.

2. MD102 – Is it known whether or not the existing condensate drain piping in the storage areas

below the stage is installed above the ceiling or below the ceiling? If above the ceiling, is it permissible to cut, cap, and label portion of pipe run horizontal in ceiling and mount new piping in an exposed manner? Response: The existing condensate drain piping is not above a ceiling. As such, all of the piping shall be removed as indicated. New condensate drain piping shall follow the path of the existing and will be exposed near the ceiling.

3. MD103 – Is it possible to have the owner provide model numbers for existing units on stage? Response: Unit type CCDA083L0B

Basic unit HLA1R11R0AG Primary coils 10CA4B000000 # 1 serial # K80H11819 # 2 serial # K80H11820

4. M102 – It appears the intent is that any ductwork exposed in the stage area be double wall. Please

confirm. Further, please clarify whether or not the below stage return ductwork must be double wall or can be single wall with external duct insulation. It may not be possible to provide true double duct below the stage without removal and reinstallation of existing ceilings/structure below the stage area. This would be very expensive and time consuming. Response: It is the intent for the outside air and return air ductwork to be double wall as shown on the drawings. There is no ceiling under the stage, just a cavity between the stage and the floor that the return ductwork is routed through. The floor under the stage is at the same level as the flor just in front of the stage. We believe the double wall duct can be installed there and would like the bids based as such.

5. M103 – Please provide load rating for existing stage and roof structure such that it may be determined the safest way to remove and install the equipment, ductwork, and piping for the job.

Response: A mobile lift may not be used. The contractor should plan a scaffolding system along with taking into account that they will need to take appropriate measures to determine the proper measures to take before loading equipment or scaffolding onto the stage.

6. E102 – Please provide manufacturer and model of existing fire alarm system controller. If there is a service contract for this system, please provide point of contact. Response: Simplex, Model 4020. There is a service contract with Simplex.

7. Do you want the intake louvers to be cleaned and painted? If so, what color?

Response: Yes, please include cleaning and painting of the outside air louvers. Color selection shall be selected by the owner during submittals, contractor shall provide color chart.

8. Has Asbestos inspection been completed on Auditorium?

Response: WJCC recently conducted the required triennial inspections. All known asbestos has been removed from Matthew Whaley. If the Contractor discovers or inadvertently disturbs any material that he knows, should have known or has reason to believe, may contain asbestos that has not been previously identified, was overlooked during the removal, was deemed not to be friable or was encapsulated, the Contractor shall stop Work in the area containing or suspected to contain the asbestos, secure the area, and notify the Owner and the Architect/Engineer immediately by telephone or in person with written notice as soon as possible. The Owner will have the suspect material sampled.

9. Can you provide a shop drawing of control upgrades?

Response: Please see attached for the 2014 shop drawings for HVAC Controls. The existing air handlers being replaced have Trane Controls but were not upgraded in 2014. The existing controllers are a legacy product. It is anticipated that it will be less expensive to provide new controls on the air handlers from the factory in comparison to removing/reusing the existing legacy controls.

Mr. Alan T. Robertson Facilities Manager WJCC Public Schools 597 Jolly Pond Road Williamsburg, Virginia 23188

ECS Project No. 07:12819

Reference: Asbestos Management Plan Review Matthew Whaley Elementary School

301 Scotland Street Williamsburg, Virginia 23185

Dear Mr. Robertson: ECS Mid-Atlantic, LLC (ECS) is pleased to provide WJCC Public Schools with the following findings and conclusions based on the review of the existing asbestos related records for Matthew Whaley Elementary School under US EPA Asbestos Hazard Emergency Response Act (AHERA) under 40 CFR 763. ECS reviewed the existing records maintained by WJCC Public Schools for general compliance with AHERA. Based on the available documentation provided within the asbestos management plan, it appears that all of the previously identified and/or assumed asbestos containing materials (ACMs) within the building(s) have been removed. Therefore, no further re-inspections or periodic surveillance for asbestos containing materials (as specified under AHERA) is required. It should be noted however that this status could change in the future if additional asbestos is discovered concealed within the building and not removed, or if any new building materials are installed for the school as part of any future renovation or new construction projects that are not covered by a signed statement by an architect, project engineer responsible for the construction, or an accredited inspector that no asbestos-containing building material (ACBM) was specified as a building material in any construction document for the building(s), or to the best of his or her knowledge, no ACBM was used as a building material in the building(s). Under 40 CFR 763 (AHERA) this letter will in part serve as a closing document to the school’s asbestos management plan. This letter along with all other existing documentation should be maintained at the school and in the central record keeping office as a record with respect to the status of asbestos in the school and be available for review by parents, teachers, school employees, and outside contractors. Parent, teacher, and employee organizations should be continued to be notified of the availability of the asbestos management plan annually. Note 1: If any renovation or demolition activities are planned within the school property, an asbestos survey is recommended prior to the renovation/demolition in the areas to be impacted in order to identify asbestos containing building materials (if any) not covered by AHERA or any

2

other building materials not readily accessible or concealed within the school building components. Note 2: In preparation of this letter, ECS relied on accuracy of the studies and reports previously performed/provided for WJCC Public Schools by third party consulting firms other than ECS. ECS did not field verify the findings/conclusions provided by others. Respectfully submitted, ECS MID-ATLANTIC, LLC
