Addendum Number Two

DOC – Kentucky State Penitentiary KSP Repair Replace HVAC System 4 Cell House

527-CC2W-SP50-00

BCCLT Project No. 25054

This addendum amends Drawings and/or Specifications and/or Addenda for the above title project, as indicated below, and is hereby incorporated into the Contract Documents as part thereof.

Bidders are required to acknowledge receipt of this Addendum in the space provided on the Proposal/Bid form.

Separate Attachments:

1. Summit Environmental Services Inc – Asbestos and Lead Paint Inspection

2. GPRS – Structural Reinforcement Scanning Report

Clarifications:

1. Refer to sheet M203.

a. Keynote #7 shall read: 32" x 30" exhaust duct up thru roof. Gooseneck termination above roof, refer to sheet M400 detail 4. Ensure that exhaust air outlet ERV-1 is at least 10’-0” away from the outside air intake.

Contractor Questions:

1. Sheet M012 states unsecured floor space will be granted for three (3) weeks per side.

At the 9/3 site visit, bidders were advised to carry two (2) weeks per side. Please confirm by Addendum which duration governs, and revise M012 accordingly.

Response: Contractor shall be allowed floor space for three (3) weeks per side.

Coordinate timing and phasing with facility.

2. What is the anticipated turnaround for background checks and badging of the construction workforce

Response: On site training will occur for two days. Background check turnaround is anticipated to be 2 weeks.

Addendum No. 2

3. Please issue the asbestos, lead-based paint, and hazardous materials survey report by Addendum. Absent a survey, bidders have no basis to quantify this work.

Response: See separately attached Asbestos and Lead Inspection Report from May 2026 by Summit Environmental Services, Inc.

4. Bidders were advised that the existing slab has been X-rayed and that rebar is marked on the floor. Why is there a schedule for S100 for the contractor to fill out.

Response: Not every location of the existing attic slab was scanned. Scanning was completed in selected representative areas of the attic slab and was completed prior to having an understanding of exactly where all of the penetrations would need to be.

As such, the documents require scanning to take place in order to adjust the opening locations a few inches in one direction or another in order to miss reinforcing steel and to cut as few bars as necessary (see sheet S203). For example, if the exact position shown cuts 6 bars in one direction and if that opening position were to shift 2” and only 5 bars would be cut, that is a good choice to make in our opinion.

It should also be noted that scanning is “approximate” and not entirely precise.

Varying conditions can be found once the concrete is cut. We are interested in knowing how many bars are cut in each direction in each location. Please provide the information requested during the course of the work.

5. Please issue the scan reports and marked-up plans by Addendum.

Response: Please see attached report by GPRS.

6. Given the existing scan data, is the Contractor still needed to perform independent concrete scanning under Specification 030502, paragraph 3.1.B, at all fifteen (15) penetrations (A–O)?

Response: Yes, please do scan each location in order to review the final position of the penetration to be cut. As discussed above and on sheet S203, it is helpful to cut the least amount of reinforcing bars as possible in each location.

7. Who is responsible for meter and tap fees on Natural Gas?

Response: Contractor shall be responsible for all fees.

8. Please provide detail for Concrete pad on M010 associated with detail 2, Phase 1A RTU-1 Install. The detail is not sufficient as it will require a large turndown due to the slope of the existing grade.

Response: See concrete slab turndown detail below.

Addendum No. 2

9. Sheet M102 states scaffolding is to be built, disassembled, and removed at the end of each day. Please confirm this is literal and confirm whether scaffolds may remain erected within the fenced "Secured Area" shown on M012. The scaffold will need to stay erected for that entire phase.

Response: Omit Photo 1 note indicating the scaffolding to be built, disassembled, and removed at the end of each day. Scaffolding may remain erected during the entire associated phase of the project. Scaffolding may remain erected within the fenced “Secured Area.”

10. Where may materials and tools be stored inside the secure perimeter overnight? If none, please confirm all material must be transported in and out daily.

Response: Tools may be stored within the secure perimeter. These tools will still require daily inventory checks.

11. Bidders were advised the controls are standalone with the ability to tie in. Please define the scope demarcation on Sheet M501 between the Temperature Control Contractor (BMS/DDC, Status Command Center Panel, Firefighter Override Panel, motorized dampers) and the Fire Alarm Contractor (duct smoke detectors, addressable control modules, remote test switches, general alarm interface).

Response: There is no existing building control system for the entire facility currently. The control system for Cell House 4 will be its own independent control system for the entire building. Prime contractor shall define scope demarcation among subcontractors.

12. Controls point list shows graphics and trends. How is this to be accomplished without tying into a controls system?

Response: Building controller shall be its own independent control system with capability for computer/laptop workstation integration. The control panel shall be located in the mechanical room with capability for remotely access through a remote data connection or through the internet. All components required shall be provided by the controls Contractor.

Addendum No. 2

13. Sheet M501 Note 1 states duct smoke detectors are furnished, installed, and wired by the Mechanical Contractor, while Sheet E200 Keynote 1 assigns duct detector installation and remote test switches to the electrical scope. Which governs, so this is carried once?

Response: Prime Contractor shall determine which discipline and sub-contractors shall provide the associated scope.

GPRS Project Manager: David Hartlage

Thank you for using GPRS on your project. We appreciate the opportunity to work with you. If you have questions regarding the results of this scanning, please contact the lead GPRS project manager on this project.

EQUIPMENT USED

The following equipment was used on this project:

• Concrete GPR Antenna: This GPR Antenna is handheld and rolls over the surface. The device displays scan data on a screen, and the operator marks detected objects on the surface in real-time. The antenna needs a reasonably smooth, unobstructed surface for scanning and cannot scan within 2”-4” of obstructions such as walls and metal tracks. Ideally, the client removes obstacles such as these before our work begins. The total effective scan depth can be as much as 18” or more with this antenna but can vary depending on the concrete conditions, composition, and other factors such as the spacing of the reinforcing. Depth accuracy depends on obtaining a precise depth calibration for the concrete. This device does not emit harmful radiation and can be safely operated while people are in close proximity. For more information, please visit: Link https://www.gp-radar.com/equipment/1600-2000-2300-2700-mhz-gpr-antenna
