Documentation of the same must be current and must have been issued by or under authority of the State of Alaska or, if documentation is from an outside jurisdiction, such documentation submitted must be of a form accepted as valid by the State of Alaska for performance in Alaska. Such documentation shall include, but is not limited to, a current Alaska business license for the business to be conducted, applicable professional licenses, registrations, and all necessary certificates.
2.0 SCOPE OF WORK
The following is presented for assessment purposes only. The final scope of work will be that agreed to as part of the final signed contract between PWSAC and the prevailing bidder. In the event there is any alleged conflict or inconsistency between the scope of work discussed in these bid documents (including the attached plans), and the scope of work in the parties’ contract, the latter will prevail.
If the Proposer has any questions regarding the scope of work and attached plans, including a belief that the bid documents are insufficiently specific, the Proposer must raise these issues prior to submitting their Proposal, otherwise they are waived. All work will require consultation with PWSAC. PWSAC will purchase the tanks and stage them in Anchorage. The Contractor shall acquire and/or furnish all other necessary materials as specified in the attached plans including but not limited to piping, fittings, lift stations, tools, and fill materials/aggregate. The Contractor shall mobilize all materials in Anchorage for PWSAC to transport to Whittier then to each site. The Contractor shall provide details as to the mobilization of all materials and aggregate to the construction site, including any needs or requests for PWSAC support, via the Anchorage Distribution Center and/or the Alaskan Challenger. A loader shall be made available for use at site upon Contractor request and all detail of its use will be formalized at the time of contract approval.
Transport to each site will require close coordination and planning with PWSAC. PWSAC has only one landing craft to service all its remote facilities. It is not available “as needed.” Further, certain sites have very specific tide restrictions for materials delivery. Finally, weather is always a factor in accessing and leaving these sites. The Contractor shall coordinate with PWSAC regarding landing craft limitations and schedule. Housing at each site shall be provided to Contractor by PWSAC, and Contractor will abide by all PWSAC policies and restrictions while at PWSAC sites. Armin F.

4.0 PROPOSAL EVALUATION PROCESS
Evaluation Process
An evaluation committee, of not less than three people, representing the PWSAC will review, evaluate, score and rank Proposals, in accordance with criteria identified in this RFP.
PWSAC also reserves the right to request oral interviews with the highest ranked individuals or firms (short list). The purpose of the interviews with the highest ranked firms is to allow for clarification to, expansion upon, and possible refinement of, the written responses. If interviews are conducted, a maximum of three firms will be short-listed. A second score sheet, with the same categories and score points used for the first evaluation, will be used to score those firms interviewed as a second evaluation. The final recommendation for selection will be based on the total of all evaluators scores achieved on the second rating.
The evaluation committee will forward a recommendation for contract award based on points awarded. The General Manager will review the results of the selection committee. The company, whose Proposal is ranked highest, subject to approval by the PWSAC General Manager, may be invited to enter final negotiations with the PWSAC for the purposes of contract award. The criteria to be considered during evaluations, and the associated point values, are as follows:

1) THE EXISTING UNDERGROUND UTILITIES WERE DRAWN USING THE BEST AVAILABLE INFORMATION INCLUDING SURFACE EVIDENCES MEASURED DURING THE SITE SURVEY, OWNER SUPPLIED ASBUILT/RECORD DRAWINGS, AND INTERVIEWS WITH PLANT MANAGERS AND STAFF. THE UNDERGROUND UTILITIES SHOWN HEREON ARE SYMBOLIC ONLY AND MAY NOT REFLECT THE ACTUAL LOCATION. 2) THESE PLANS WERE PREPARED USING INFORMATION FROM A SITE INSPECTION BY AN R&M ENGINEERING-KETCHIKAN REPRESENTATIVE CONDUCTED ON 9/21-23/2020. THIS SITE INSPECTION INCLUDED A SITE SURVEY USING HIGH-PRECISION, TRIMBLE R8/R10 GPS HIGH-PRECISION, TRIMBLE R8/R10 GPS RECEIVERS DIFFERENTIALLY CORRECTED AND PROCESSED USING TRIMBLE BUSINESS CENTER V 5.10 SOFTWARE 3) THESE PLANS DEPICT STRUCTURES AND FEATURES PERTINENT TO THE WASTEWATER TREATMENT SYSTEM DESIGN ONLY. NOT ALL DECKS, AWNINGS, ETC. ARE SHOWN. ADDITIONALLY, ANY UNDERGROUND UTILITIES OR FEATURES NOT MADE APPARENT BY EVIDENCES DESCRIBED IN NOTES 1 AND 5 ARE NOT SHOWN. 4) THE VERTICAL DATUM FOR THIS PROJECT IS MEAN LOWER LOW WATER 5) A PIPE CAMERA VIDEO PERFORMED ON MAY, 19, 2017 WAS PROVIDED BY THE CLIENT TO ASSIST IN RE-CREATION OF THE EXISTING SEWER LINE LOCATIONS, TYPES, AND SIZES. ADDITIONALLY, NO BREAKS OR MAJOR FLAWS WERE FOUND IN THE SEWER MAIN FROM THE MAIN HATCHERY BUILDING SERVICE LINES TO THE EXISTING SEPTIC TANK AT THAT TIME. 6) NO PROPERTY INFORMATION IS SHOWN ON THESE DRAWINGS. IT IS THE RESPONSIBILITY OF PWSAC TO COORDINATE ALL LEASES WITH THE STATE OF ALASKA AND THE U.S. FOREST SERVICE AS NEEDED FOR CONSTRUCTION AND/OR ENSURE THAT ALL PROPOSED UPGRADES SHOWN ON THESE PLANS DO NOT CONFLICT WITH EXISTING LEASES AND LAND USE PERMITS. 7) IF THE EXISTING MARINE OUTFALL IS FOUND TO BE BROKEN, UNSECURED, OR DISCHARGING TO A DEPTH SHALLOWER THAN SHOWN ON THESE PLANS; CONSULT THE DESIGN ENGINEER. THE LINE MUST BE REPAIRED, EXTENDED AND SECURED, OR REPLACED AS NECESSARY. 8) CLIENT OR CONTRACTOR SHALL USE TRACER DYE TO VERIFY ALL HATCHERY WATER DISCHARGES (FLOOR DRAINS, ETC.) HAVE BEEN REMOVED FROM THE DOMESTIC WASTEWATER COLLECTION, TREATMENT, AND OUTFALL SYSTEMS. ADDITIONALLY, ANY OTHER NON-DOMESTIC WASTEWATER IS NOT PERMITTED TO DISCHARGE TO SAID SYSTEMS. 9) GREASE TRAPS SHALL BE INSTALLED ON ALL KITCHENS. 10) THESE PLANS SHALL BE SUBMITTED TO THE LIFT STATION MANUFACTURER OR AREA DISTRIBUTOR FOR COMMENT PRIOR TO ORDERING LIFT STATIONS OR PUMPS. 11) THE WWTP MUST BE INSTALLED BELOW THE GROUND SURFACE OR IN AN ENCLOSURE INSULATED AND HEATED TO A MINIMUM OF 50°F.
