From: GSBS ARCHITECTS

Project Name: Tarrant County Administration Building- 1st through 5th Floors Renovations

GSBS Architects Project #: 2016.077.00

This addendum shall be considered to be part of the contract documents for the project referenced above. Where provisions of the following supplemental information differ from that contained in the original contract documents, this Addendum shall govern and take precedence.

Bidders are hereby notified that they shall make any necessary adjustments in their estimate on account of this Addendum. It will be construed that each Bidder’s proposal is submitted with full knowledge of all modifications and supplemental data specified therein. Acknowledge receipt of this addendum in the space provided on the Bid Form. General:

1. Specific note is brought to the Phase I and Phase II of the project and Contractor shall provide bid according to Division 1 Summary of Work as outlined on Sheet A4.1 and as further directed by Tarrant County Purchasing Department. Bidding under this advertisement is Phase I only.

2. Regarding the existing building controls system: Contractor shall provide and install DDC controls on new Fan Powered Boxes and add to existing Reliable Controls Building Automation System.

3. The area designated for contractor to store materials will be 2nd Floor Administration Building in the old Credit Union space (northeast corner of the building). The area is currently finished and the finishes will need to be preserved throughout the construction duration. Contractor shall preserve and provide protection to all finishes including the flooring within the space. Contractor may utilize this space for field operations during the construction duration.

4. Restroom facilities will be the responsibility of the Contractor. Workers will not be allowed to utilize the existing facilities within the building. The dock area cannot accommodate the temporary restroom facilities. Temporary toilet facilities shall not be located on owners property.

5. The Contractor shall provide their own rubbish disposal units and cannot utilize the existing dock for the waste disposal containers.

6. The existing dock area can be utilized for the loading/unloading of construction materials only and shall be cleared of vehicles immediately upon completion of loading/unloading.

7. Parking for construction workers is not provided by the county. 8. Bidder Question: “Since the restroom corridors are not specifically calling for flooring

demolition, and the finish schedule calls for VCT in the corridors, are we just to replace the VCT and rubber base as patch work where walls are changed or does the entire corridor need to be demoed and replaced?” Answer: Removal of existing finishes are required in the restroom corridors prior to placement of newly scheduled materials. First floor, where terrazzo is currently installed will remain as existing terrazzo. Minimal patchwork of existing terrazzo is required where existing partitions are removed. Matching epoxy terrazzo shall be provided by contractor.

9. The Existing Fire Alarm is a Simplex Grinnell System. Contractor shall provide devices and coordinate with existing fire alarm manufacturer/contractor for the proper design, extension, programming and new devices required for the existing system, meeting the requirements of the Authority Having Jurisdiction (AHJ) for the project.

10. It is the intent to remove and re-install doors and frames as necessary to achieve a “like new condition.” If contractor wishes to provide new frames where salvage of frames and final finish are not likely to result in a “like new condition,” contractor’s option is to replace demolished frame with new. In any case, contractor shall replace the frame of doors if swing is reversed from original installation.

11. Clarification: Per Sheet P2.1 and P2.2, General Note #5 to provide one isolation valve for domestic water service on each floor. Contractor shall provide the number of isolation valves required to isolate the domestic water on each floor and provide for any additional isolation valves required for the further isolation required for phased construction of the domestic water supply on each floor. For bid purposes, include the cost and installation of two (2) isolation valves per floor and provide the unit price cost and installation of an isolation valve on the bid form provided.

12. Clarification: Sheet A4.1, Temporary Facilities: Contractor shall take necessary control measures which prevent any migrating of dust beyond the construction zones. Incorporate measures to clean up immediately, any dust and debris tracked into occupied spaces. Temporary secure barriers (stud and gypsum wallboard) shall be constructed to prevent public migration from front of house to back of house corridor through restroom corridors. This Secure partition construction is particularly important on levels 1, 2 and 4. The passage corridors of occupied spaces in back of house must be maintained at all periods of construction on each floor.
