April 25, 2025 Addendum #5

TO ALL PROSPECTIVE CONTRACTORS

This is an Addendum to and shall be considered as part of the original Bid package for the above-mentioned Bid. Contractors are requested to acknowledge receipt of this Addendum with their

Submission.

CLARIFICATION TO QUESTIONS ASKED/RECEIVED:

1. The new plans call for 16" Snap-Lok .040" aluminum panels. This as-built plan you sent out today shows the existing building being 36" PBR panels. Are we really going to mix panels on the same building?

a. AE RESPONSE: Please note that the intent is to match the existing roof panel. 36” PBR panels meeting Risk Category IV wind criteria are acceptable in place of the 16” Snap-

Lok 0.40” aluminum panels. Revised Specification section 07 41 13 Metal Roof Panel is provided.

b. Please note that the panels are to be installed over cover board and rigid insulation as shown on AE515 and AE516. This system is to meet the requirements of the FBC Energy

Code for continuous 4.5” rigid board insulation above deck and meeting R-27ci. No breaks are allowed in the insulation board to meet the continuous insulation requirements. Refer to AE301 for insulation requirements.

2. Our electrical sub is needing some clarification on quoting to replace the existing lighting in Fire

Station #83. Are you wanting all lighting - inside and out - quoted? Do you have a lighting schedule of the existing lighting.

a. AE RESPONSE: Please provide lighting as shown on sheet E-101 LIGHTING PLAN.

3. Wall materials? One place it is calling out HARDY BOARD EXTERIOR PANEL OVER PMB

EXTERIOR, MATCH EXISTING, Another place: 074646.A01 FIBER CEMENT SIDING WALL

PANEL SYSTEM, then the spec says Foamed-insulation-core metal panels and Exterior Wall

System: Manufacturer's standard concealed-fastener, flush-profile, foamed-insulation-core metal wall panels.

a. If wall panels are to be IMPs (Insulated metal wall panels) We need to pick a profile, with, thickness, finish, etc.

i. AE RESPONSE: Please note that the exterior wall finish is a Fiber Cement Siding

Wall Panel System with Hardy Board Exterior Panel as basis of design. Hardy

Board is a fiber cement siding wall panel system. Please refer to C1/AE501 for typical exterior plan detail of corner condition for reference and specification

April 25, 2025 Addendum #5 section 07 46 46. Basis of design product is provided on page 07 46 46 -5, Part

C1/AE501 for typical exterior plan detail of corner condition for reference and specification section 07 46 46. Basis of design product is provided on page 07

46 46 -5, Part 2.2. Revised Section provided for additional clarification.

d. Are the wall panels horizontal as drawn or vertical as listed in spec?

i. AE RESPONSE: Wall panels are to match existing texture for hardie board panels (Fiber Cement Wall Panels, 07 46 46). Basis of design product is provided on page 07 46 46 -5, Part 2.2. Revised Section provided for additional clarification.

4. Are we supplying metal girts in the walls or are they using steel stud walls?
