FOUS Water Waste System Improvement Ques�ons for Solicita�on # 140P6324B0004

Ques�on 1: Updated from previously posted ques�ons/answers atached to Amendment 001

If the sewer laterals that were previously installed are not visible, is the contractor responsible for exploratory excava�on as part of the bid or would this be a T&M change order? If it is to be part of the base contract, what bid item would you like it under for the schedule of values?

Government Response:

Approximately half of the drain field chambers have been installed. Depth of exis�ng chambers are at 24 inches and are iden�fied on the plans. The contractor will be responsible for carefully opening the ends of the drain field lines to expose them and �e them into the overall drain field system as show on the plan set. The contractor will be required to expose the ends (eight in total) to allow connec�on to the connector piping. The government es�mates the contractor will u�lize two to three days for digging work using a backhoe bucket where approximately 24 square feet per end trench will be needed. The government will provide addi�onal measurements and GPS readings (within 1-3 feet) taken of the exis�ng work prior to onsite work commencing. This work should be included in the contractor’s firm fixed price base contract lump sum bid. Connec�ng the exis�ng drain field chambers shall be under the “Drain Field with Insulated Manhole” schedule of values item details.

Updated: Flags/markers have been set to iden�fy approximate loca�ons of exis�ng chambers.

Ques�on 2: No update.

It is stated under Sec�on 16420 Submersible Grinder Pumps and Controls, 2.2 Pump Control Panel, O.

Panel Indicator Lights, that 4 addi�onal bulbs for each size bulb used in the panel door is required. We use LED colored lights for our panel door indicator lights that have a long lifespan, htps://new.abb.com/products/1SFA611621R1042/mlbl-04g , will you s�ll require (4) bulbs of each size and color if LED is to be used instead? The top alarm light as it is an LED fixture, spec is calling for (2) spare bulbs, but these come as whole units and last for a very long �me as well.

Government Response:

Please provide spare bulbs as per specifica�on. LED lights will be considered “or equal”.

Ques�on 3:

Can we put an office trailer/living quarter on the exis�ng concrete pad with u�lity hook ups?

Government Response:

Government will provide a designated area during the performance period for an office support trailer.

This designated space will be discussed during pre-construc�on mee�ng or when awardee is on site.

Living quarters within the park near the site will not be authorized for this requirement. Contractor can contact local RV parks nearby for other living arrangements.

Ques�on 4:

Will the awarded contractor be responsible for previously installed materials?

Government Response:

The contractor will not be responsible for previously installed materials, however if the awarded contractor discovers that repairs are needed to previously installed materials, the contractor will need to no�fy the Contrac�ng Officer regarding the discovery of damaged materials and if necessary, may request equitable adjustment using the firm fixed price clauses contained within the contract. If the awarded contractor causes damage to previously installed materials, the contractor will be required to repair/replace at no cost to the government.

Ques�on 5:

Regarding the bore that has already been completed, has it been pressure tested? Did it pass the pressure test? Will it need to be tested again?

Government Response:

The previously installed force main had not been pressure tested. The new and exis�ng force main will require pressure tes�ng upon comple�on per specifica�ons. If the previously installed exis�ng force main fails pressure tes�ng, the contractor may request equitable adjustment under the firm fixed price clauses within the contract.

Ques�on 6:

What was the circumstance(s) that occurred to have this project not originally be completed?

Government Response:

The original project ran into a rela�vely small archeological anomaly. The Na�onal Park Service, at that �me, did not have a mi�ga�on plan for dealing with archeological discoveries in place to move forward with the project. A mi�ga�on plan is now in place to be able to complete the project. If unan�cipated archeology is found, the NPS and the contractor can adjust and relocate to complete the planned facili�es using the clauses contained within the firm fixed price contract.

Ques�on 7:

The project is calling for 6” of cer�foam insula�on board. Can it be 3 layers of 2” thick cer�foam?

Government Response:

The contractor may provide “or equal” materials submitals that will be evaluated during the submital approval process a�er award and prior to construc�on.

Ques�on 8:

At what �me does the contractor become liable for pumping of the exis�ng sep�c tank? What sep�c pumping company are they currently using?

Government Response:

The contractor and the NPS will be responsible for keeping the housing units sewered during the construc�on of this project. The NPS will be responsible for pumping the exis�ng tanks un�l the �me that the contractor takes them offline to connect to the new tanks and li� sta�ons. Coordinate sep�c tank pumping with the Facility Manager. The Facility Manager at FOUS can supply a contact for sep�c tank pumping.

Ques�on 9:

The use of duc�le iron fi�ngs on PVC seems unusual. Is this for sure going to be the requirement? SCH 40 PVC fi�ngs for non-pressurized sep�c would seem to make more sense.

Government Response:

The contractor may provide “or equal” materials submitals that will be evaluated during the submital approval process a�er award and prior to construc�on.

Ques�on 10:

Preference would be to use pea rock for backfill/ground stabiliza�on around sep�c tanks and li� sta�ons.

Would this be a possible op�on?

Government Response:

The contractor may provide “or equal” materials submitals that will be evaluated during the submital approval process a�er award and prior to construc�on.

The Government does not an�cipate that there will be a need to respond to addi�onal ques�ons. The Government feels that contractors should be able to provide a lump sum price considering the specifica�ons, drawings, and updated ques�ons and answers.
