About this file
This document is a response to bidder questions for Solicitation No. 696-FD-23-B014-B, the Ferguson Water Treatment Plant project in Texas. The project involves constructing two new 150,000-gallon potable water storage tanks and a new 1.5 MGD potable water plant, including new foundations, cathodic protection, and all new piping and valves. Jacobs Engineering Group is the designer. The solicitation has a bid due date of September 15, 2023 at 3:00 PM. Responses address questions related to instrumentation details, control panels, MCC equipment, material storage, scheduling software, staffing requirements, stockpiling of earth, and American Iron and Steel requirements. An addendum was issued modifying specification 40 90 02.05 for the magnetic level indicator.
The solicitation is open to out-of-state bidders. The performance period is 600 calendar days, though bidders can propose an alternative duration. Weather days are calculated based on working days, not calendar days. Existing equipment and materials from the demolition must be salvaged for the owner. Material substitutions, such as metal wall panels for masonry, are generally not allowed. Reuse of existing soil is permitted with testing and approval.

| Answer |
| 1 |
| FI-1100, FI-1402 & FI-4231 are shown on the contract drawings but are not included in the Instrument List in Specification 40 90 01 (starting on page 51). Please confirm the PIC contractor to provide as part of Instr. Detail 4091-043? Please provide the Comp Code and applicable specification? |
| Yes, the PIC contractor shall provide the rotameters as part of the Instrument Detail 4091-043. The rotameter flows are highly dependent on the analyzer flow requirements and are expected to be sized appropriately by the analyzer panel builder. Refer to analyzer panel example sheets added as an addendum to specification 40 90 01. |
| 2 |
| Please advise the Inst. Detail for FI-4211 & FI-4213? |
| Refer to Specification 40 91 02.03 Section 2.4 – F16 Flow Element, Rotameter for instrument detail. Refer to Detail 4097-002 added to new sheet 99-N-504. |
| 3 |
| Please confirm the Instr. Detail for the level switches on page 52 of Specification 40 90 01 is 4091-248? If not please provide. |
| The level switches are not the same type as shown on detail 4091-248. Refer to the component code descriptors (e.g. L112, and L115) on specification 40 91 02.05 for the type of level switch required. Refer to Details 4091-027 and 4091-250AG added to new sheet 99-N-504. |
| 4 |
| LCP4210 on 09-N-006 is not included in specification 40 90 01. Please confirm if the PIC contractor is to provide this under this specification section? |
| Refer to specification 44 42 56.02 Section 2.2.E for the requirements of LCP4210. It is currently assumed that this may be provided by pump vendor, but the general contractor has ultimate decision on who supplies each item on this project. |
| 5 |
| MCC120 on 09-N-000 is not included in specification 40 90 01. Please confirm if the PIC contractor is to provide this under this specification section? |
| The general contractor has ultimate decision on who supplies each item on this project. The MCC120 shall be provided under specification 40 90 01 since the existing pump is currently controlled out of the existing control house which will be demolished. |
| 6 |
| Is the PIC contractor responsible for furnishing and installation of the level indicator LI 2001 on 09-N-009? Or will it be provided with the tank? |
| The general contractor has ultimate decision on who supplies each item on this project. Refer to the specification modification listed below regarding the magnetic level indicator. Refer to Detail 4091-025 added to new sheet 99-N-504. |
| 7 |
| LCP-X on 09-N-009 is not included in specification 40 90 01. Please confirm if the PIC contractor is to provide this under this specification section? |
| LCP-X on Sheet 09-N-009 is in error. This has been corrected to read LCP-2001 and has been added to the control panel schedule attached. |
| 8 |
| It states that “payment for Materials stored on & offsite must be scheduled for installation within 60 days of arrival on the job-site and is properly stored and protected”. Due to the current market conditions, can this be voided so that full payment for materials is accepted without having to fall within any number of days of installation? This mitigates a large amount of risk for both the Contractor & Owner on schedule delays. |
| Follow the terms of the contract solicitation. |
| 9 |
| Is Primavera (P6) scheduling software required? Can Microsoft Project be utilized instead? |
| Yes, Microsoft Project may be utilized. |
| 10 |
| Can the QC Manager be a Project Manager or Superintendent? |
| No |
| 11 |
| Can some dirt be stockpiled for later facility use? |
| Yes, please refer to specification 31 22 00 Section 3.3.J for further details on stockpiling earth. |
| 12 |
| Can we hold material on site for over 60 days? |
| Follow the terms of the contract solicitation. |
| 13 |
| Does American Iron and Steel Use (Section I, Subpart 14.11 ‘Required Use of American Iron and Steel Products) per Texas Government Code, Section 2252.202 apply to all materials and equipment on the project? Section 33 16 13.12 species glass-fused, bolted-steel tanks. There is only one US located glass- tank manufacturing facility, CST Industries Aquastore facility in Dekalb, IL. CST Industries distributes to Texas through one entity only: Texas Aquastore. If American Iron & Steel applies to this product, only one supplier/subcontractor will be compliant. |
| Yes, the American Iron and Steel Use applies to all materials and equipment. |
With regard to 33 16 13.12, note that this current bid set does not include glass-fused bolted tanks; these were removed and replaced with AWWA D100 welded steel ground storage tanks in this iteration of bidding. Verify that you are using the current plan sets dated November 23, 2022.
| 14 |
| With the ongoing issues with supply chain availability for products, are the above-ground bolted steel tanks going to be allowed to be used on this project that are made overseas? |
| With regard to 33 16 13.12, note that this current bid set does not include glass-fused bolted tanks; these were removed and replaced with AWWA D100 welded steel ground storage tanks in this iteration of bidding. Verify that you are using the current plan sets dated November 23, 2022. |
| 15 |
| For the bolted-steel tanks, would a more standard ‘T’ vent or mushroom-shaped gravity vent be acceptable? The shown ‘Gooseneck’ vent is not typical of AWWA D103; both ‘T’ vents and gravity vents have been used on other TCEQ projects and are more standardized to bolted-steel tanks. |
| With regard to 33 16 13.12, note that this current bid set does not include glass-fused bolted tanks; these were removed and replaced with AWWA D100 welded steel ground storage tanks in this iteration of bidding. Verify that you are using the current plan sets dated November 23, 2022. |
| 16 |
| For the bolted-steel tanks, what is the roof hatch size required? Section 33 16 13.12, Subpart 3.3.C.3.e calls for a 24X15 roof hatch. The drawings (40-D-102) show a 36”x36” roof hatch. A knuckle roof cannot accommodate this hatch dimension so either the smaller hatch or an alternate roof style is required. |
| With regard to 33 16 13.12, note that this current bid set does not include glass-fused bolted tanks; these were removed and replaced with AWWA D100 welded steel ground storage tanks in this iteration of bidding. Verify that you are using the current plan sets dated November 23, 2022. |
