About this file

This is a Request for Information (RFI) clarification document for Battle Creek Public Schools' Ann J Kellogg building interior chilled water piping insulation project. The document addresses bidder questions regarding insulation material specifications and piping thickness requirements. The primary clarification confirms that bidders should base their bids on Armaflex insulation with 520 adhesive for both piping and fittings, rejecting the use of self-sealing Tubolet SS or self-seal Armaflex products due to durability concerns with adhesive longevity and material porosity. The specifications indicate that piping thickness should be determined by the manufacturer's product specifications based on water line sizing as detailed in the existing mechanical plans provided in the project manual. The document also references plan revisions for additional spaces in Areas 1 and 4 that were not included in the initial RFP project manual.

No pricing information, contract term details, bid due dates, or award information is specified in this clarification document. The communication serves primarily to align bidder understanding of material specifications and direct contractors to reference existing mechanical plans for determining appropriate insulation thickness based on chilled water line sizing requirements.

Battle Creek Public Schools: Ann J Kellogg Piping Insulation – Clarification #1

RFI Responses;

Q; In reading the specifications and in Part 3, A. I would not recommend Tubolet SS or any self-seal Armaflex. I have seen this installed on piping and it never stays closed. The adhesive only last temporally. This type is also very porous.

Thoughts?

A; Plan base bid around Armaflex and 520 adhesives on piping and fittings.

Q; I didn’t see the thickness for the chilled water piping on the specs. There was ½” on the cw. I am not sure this would be thick enough for chilled.

A; The specs may not call this out. However, Scope of work should dictate the manufacturer’s product chosen within base bids, should dictate the thickness based on water line sizing. This line sizing is shown on the existing mechanical plans in the project manual.

Plan Revisions;

See attached plans not included in initial RFP project manual. These are additional spaces to Areas 1 & 4.
