REQUEST FOR PROPOSALS PWSAC WASTEWATER UPGRADES Page 3 of 7
Award will be made to the most qualified Proposer, whose offer is
deemed most advantageous to the PWSAC, all evaluation criteria
considered. The PWSAC may choose to interview only the top-ranking
firms as based on proposal review and scores. Unsuccessful offerors
will be notified.
1.10 Licenses and Certification
Proposers shall include with their Proposals copies of all
licenses, certificates, registrations, and other credentials
required for performance under the contract. 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

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. Koernig Hatchery, Prince William Sound: See attached
plans. (Final plans will be provided prior to construction.) Time
if of the essence and all work MUST be completed by September 30,
2021.

estimated reimbursables.
Cost will be evaluated using a ratio method after all qualitative
scoring is completed. The Proposal with the lowest cost receives
the maximum points allowed. All other Proposals receive a
percentage of the points available based on their cost relationship
to the lowest cost Proposal. The following formula will be
used:
• lowest cost Proposal/cost Proposal being evaluated (x) maximum
points available =
awarded points for Cost criteria.
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:

Qualifications and Experience of the firm 10 Points
Key Project Staff and Subconsultants 10 Points
Methodology, Approach, Timeline 20 Points
Cost 50 Points
Total Points 100 Points
5.0 Qualitative Rating Factor
Firms will be ranked using the following qualitative rating
factors, excluding cost, for each RFP criteria:
1.0 = Outstanding .8 = Excellent .6 = Good .4 = Fair .2 = Poor 0.0
= Unsatisfactory
The rating factor for each criteria category, except for cost, will
be multiplied against the points available to determine the total
points for that category.
6.0 SELECTION PROCESS
The Proposer with the highest total evaluation points will be
invited to enter contract negotiations with PWSAC. If an agreement
cannot be reached with the highest ranked Proposer, the PWSAC shall
notify the Proposer and terminate the negotiations. If Proposals
are submitted by one or more other proposers determined to be
qualified, negotiations may then be conducted with such other
Proposers in the order of their respective rankings. This process
may continue until successful negotiations are achieved. PWSAC
reserves the right to reject any and all Proposals submitted.

1) THIS WASTEWATER TREATMENT PLANT PLAN DEPICTS THE TREATMENT ORDER
OF THE PROPOSED SYSTEM. TANK LAYOUT/LOCATION IS PERMITTED TO VARY
BASED ON SITE CONDITIONS. FURTHERMORE, THE PRIMARY TREATMENT AND
RECIRCULATION/PUMP TANK MAY BE SPLIT INTO MULTIPLE, SEPARATE TANKS;
CHAMBER VOLUMES SHOWN ON THIS WWTP MUST BE MAINTAINED. ALL
MODIFICATIONS MUST BE APPROVED BY THE DESIGN ENGINEER BEFORE
IMPLEMENTATION. 2) THE SYSTEM SHALL BE INSTALLED COMPLETELY BELOW
GRADE, ABOVE GRADE IN A HEATED ENCLOSURE, OR A COMBINATION OF BOTH.
3) INSTALL SJE RHOMBUS DUPLEX DEMAND/TIMED CONTROL PANELS AND XPERT
ALERT REMOTE MONITORING SYSTEM IN WEATHER PROOF LOCATION OR
HOUSING. 4) EACH STA-RITE PUMP SHALL SUPPLY PRIMARY TREATED WASTE
WATER TO THE AEROCELL PODS ON AN ALTERNATING TIME BASIS. AFTER THE
WATER PASSES THROUGH THE PODS, 80% SHALL FLOW BACK TO THE
RECIRCULATION/PUMP CHAMBER, AND 20% SHALL CONTINUE ALONG THE
TREATMENT AND EFFLUENT DISPOSAL PATH. 5) TANKS THAT ARE BURIED MUST
BE ANCHORED PER MANUFACTURER RECOMMENDATIONS. 6) "ALTERNATE A"
SHALL UTILIZE THE SAME WWTP PLAN SHOWN ON THIS SHEET WITH THE
EXCEPTION OF THE 10,000 GALLON XERXES TANK. IN PLACE OF THIS TANK,
INSTALL (2) XERXES PRIMARY TREATMENT TANKS AT DIFFERENT LOCATIONS
ON THE SITE (PER PLAN) AND A 4,000 GALLON SINGLE CHAMBERED XERXES
RECIRCULATING/PUMP TANK IN THE WWTP. ALL OTHER COMPONENTS AND
TREATMENT ORDERS SHALL REMAIN IDENTICAL.
