About this file
This is Amendment No. A-001 to Solicitation No. 696-FD-24-P040 issued by the Texas Department of Criminal Justice (TDCJ) Contracts and Procurement Department. The amendment provides answers to technical questions regarding air rotation unit specifications and extends the bid opening date from February 28, 2025, at 3:00 PM to March 14, 2025, at 3:00 PM. The questions addressed concern wind qualification data, structural performance requirements, casing leakage performance, and wall insulation specifications for the air handling units. The amendment includes a complete updated specification section (23 73 13 - Air Rotation Units v.20240906) with detailed technical requirements for the chilled water cooling and gas-fired heating air rotation system.
The amendment establishes three approved manufacturers for the custom air handling units: Daikin Custom AHU, Engineered Air, and Temptrol, subject to full compliance with specifications. Regarding financial requirements, the amendment clarifies that surety letters will not be accepted in lieu of bid bonds. The document also provides clarification about electrical panel locations for buildings J1-J4, noting they are located in the electrical room on the first floor below the large mechanical room and just inside the main entrance, as was shown during the site visit. The amendment includes comprehensive technical specifications covering construction requirements, electrical controls, fan systems, heat exchangers, cooling coils, filters, dampers, and other components.

6 I realize that we are way past the question deadline but I feel I should point out that nowhere in the specifications or on the HVAC equipment schedule drawing does it say or give a basis of design manufacturer for the Custom Air Handling Units. I know that we are supposed to bid per the basis of design equipment unless another manufacturer is approved 21 days prior to the bid date. Do you know if any manufacturer has been approved? Is there any way to find out who is the basis of design on the air handling units? Please advise.
List of approved manufacturers:
Daikin Custom AHU Engineered Air Temptrol
7 On J1-J4 the electrical drawings do not show locations of electrical panels.
On page M-101 note 10 & 11 it talks about new location for 3 lighting panels Relocated from large mechanical rooms.
It does not state what panels are getting relocated or feeder sizes or any information?
What do we do here?
For bldgs. J1 to J4 the electrical panels referenced in the drawings are located in the electrical room, which is on the first floor, below the large mechanical room and just inside the main entrance.
This electrical was pointed out during the site visit.
Approved Substitutions:
1. Daikin (listed in specs) Note: Subject to full compliance with the specifications
2. Engineered Air
DJS40/C/O/V
Engineered Air Engineered Air Note: Subject to full compliance with the updated specification - 237313 Air Rotation Units v.20240906
