QUESTIONS AND ANSWERS

Q1. Geocomposite venting layer: Sheet 10 of 17 shows 50’ on center spacing for the venting. Sheet 14 of

17 states vent spacing of 100’. Please confirm vent spacing required.

A1. The vent spacing and the spacing of each GGVL shall be consistent – 50 feet. The note provided on

Sheet 14 for Detail 40C detailing the spacing of the gas vent, shall be revised to state:

“RECOMMENDED SPACING IS ONE (1) VENT EVERY 50 LF CENTERED OVER 3” DIA HOLE.

IN ADDITION ONE (1) VENT SHALL BE INSTALLED AT EACH CORNER OF EACH

TREATMENT CELL.”

Q2. Are there any detail drawings of the Flow Diversion Structure?

A2. No there are no details. We recommend each bidder schedule a site visit to view the existing Flow

Diversion Structure.

Q3. Should there be valves installed to both the influent lines between the Flow Diversion Structure and the Fermentation Pond and the New Cell 4?

A3. No

Q4. Please provide the specification related to the gas venting system.

A4. Will provide the Standard Technical Provision sections that are referenced on Page 4 of the Scope of

Work. The standard specifications for the GGVL system are provided in TP Section 40.

Q5. Please provide the specification for the HDPE liner.

A5. Will provide the Standard Technical Provision sections that are referenced on Page 4 of the Scope of

Work. The standard specifications for the HDPE liner are provided in TP Section 40.

Q6. Please confirm that all piping is to be C900 PVC (With the exception of where Ductile Iron Pipe is indicted).

A6. Cannot confirm, as not all piping will be C900 PVC. The type of pipe will vary as follows:

The 24” diameter inlet piping shall be C900 PVC pipe (in accordance with TP-4003.A.1)

The 18” diameter transfer piping shall be C900 PVC pipe (in accordance with TP-4003.A.1)

The 18” diameter gravity sewer pipe responsible for transferring the treated effluent flows from lagoon outlet to the Wetland Lift Station shall be SDR-35 pipe (in accordance with TP-603.A.1)

Q7. What elevations (or feet above base of cells) are used for high level and drain pipe intakes?

A7. Please refer to the multiple details provided in the Construction Planset depicting the elevations of the lagoon floor, drain piping (lower), and high level piping (upper). Please note that the pipe invert levels/elevations vary based on the type of piping structure. Refer to Sheets 7 and 14 to determine the respective pipe invert elevations.

Q8. Are there regulatory requirements regarding the handling, mixing, and storage of biosolids?

A8. Yes, the successful Contractor will be required to comply with the applicable OSHA requirements for the occupational handling of biosolids. The Contractors intended actions must be reported in the

Safety Plan at the onset of construction.

Q9. Please provide the specification to the dual-channel ultrasonic wastewater flow meters and a wiring diagram.

A9. The first two paragraphs featured in STP 7.0 (amending TP-42.02.05.F) shall be replaced with the following:

A dual-channel ultrasonic flow meter shall be installed in the existing valve pit as shown in the construction drawings. The ultrasonic flow metering system shall consist of a Graphic LCD display, two

(2) sets of transducers that are to be clamped (non-wetted installation), in-parallel on the pressurized lateral pipe, and all necessary cables and clamping appurtenances to be fully operable.

Each transducer set shall be capable of acoustically communicating (generating and receiving ultrasonic signals) to measure the velocity, volumetric, and totalized flows of clean liquids or liquids with small amounts of entrained solids (effluent). The flow meter shall measure and indicate flow rates from -40 to

+40 ft/sec with ±0.1% reading accuracy. The ultrasonic flow meter shall be the AquaTrans AT868

Panametrics Liquid Flow Ultrasonic Transmitter as manufactured by GE, or equal.

Q10. Is there a projected award and NTP date?

A10. It is the intent of the Indian Health Service to award and issue the NTP as soon as the current circumstances allow – upon the dissolution of the standing public health mandates and it is deemed safe by IHS and the Pueblo leadership to allow activities to proceed. In consideration of the State of New

Mexico Governor’ s announcement to extend the State’s public health emergency order until May 15th, as of today (April 23, 2020) IHS does not foresee the NTP being issued any sooner than May 16th. Please understand this date is tentative and subject to being postponed to ensure the safety of all involved parties.
