1.            Project Background.

Bonneville’s 1st Powerhouse has 10 main units and one station service unit requiring new intake trash racks. Each main unit consist of three slots. Each slot has six racks – one bottom and five top racks. The station service unit has one top rack, four intermediate racks and one bottom rack. All main unit trash racks are similar in design. The existing Bonneville Powerhouse I trash racks were originally installed in 1937 and are now 80 years old. As part of annual maintenance, these trash racks are cleaned and inspected, except the lower racks which are left in place to prevent debris from entering the units. The last time the lower trash racks were removed and inspected was 1983.

2.            Project Scope.

a. The following information represents the project objectives:

i.             Pre-site survey.

ii.            Fabrication and installation of 162 - 22'-1 1/4" long, 1'-7 1/2" wide x 12' tall new trash racks.

iii.           Removal and disposal of 174 existing trash racks. Disposal of an additional 29 existing trash racks that are being stored onsite.

iv.           Debris removal or debris relocation (brush, tree trunks, etc.), and relocation of sediment to ensure successful installation of the trashracks. The volume of debris and sediment is approximately 800 cubic yards total in a 20 ft by 1000 ft area, down to a -2 EL., at an approximate water depth of 70 feet.

i.             This large volume is assumed necessary so that the area stays clear long enough for the trashrack installation work to occur. This volume could be reduced if schedule sequencing is in such a way that the trashrack removal/installation can follow quickly behind the debris removal/relocation.

ii.            Debris includes 12"-24" diameter trees. There are some 36" diameter trees that cross multiple units.

iii.           Debris in front of the units ranges 1-15 feet.

v.             Debris removal/relocation behind existing trashracks, as necessary, to install the new trashracks.

i.             The trashracks spacing is 6” on center.

vi.           Installation of 162 new trash racks and 12 additional trash racks that are already onsite.

NOTE: USACE would greatly appreciate input from industry on the best means of clearing the debris and sediment to allow for access to the track racks for replacement. 

Several options have been discussed, including:

1. Removing all debris and sediment from the water and disposing of in accordance with all federal, state, and local laws.

2. Removing only debris and move sediment upstream from the face of the dam, leaving it in the water.

3. Moving the debris and sediment upstream from the face of the dam, leaving it in water.

b. Anticipated Construction Schedule:  CENWP intends to advertise (09-2025) and award (11-2025) a Construction Contract with estimated construction completion by the end of calendar year 2027.

c. Estimated Construction Cost (ECC):  The current ECC is between $10,000,000 and $25,000,000. Ref. FAR 36.204 Disclosure of Magnitude and DFARS 236.204 Disclosure of Magnitude.

d. Number and Type of Contracts: NWP contemplates awarding one (1) Firm-Fixed Price Construction contract. Maximum Small business participation is being sought at both the Prime and subcontracting levels.

e. Anticipated Source Selection Process:  The expected method to determine the best value to the government is Invitation for Bid.

3.            Project Specific Constraints and Challenges:

a.            Debris removal and divers are only allowed during the In-Water-Work (IWW) window, December 1 – February 28. Removal and installation of the trashracks can occur outside of the IWW. This needs to be carefully coordinated as debris may need to be removed behind the trashracks for successful installation of the trashracks.

b.            It is assumed that debris removed from the river would need to be tested for environmental compliance prior to disposal.

c.            When a boat or barge is in the water, assume all units are out of service.

d.            Any diving, at any time of the year, requires at least three main units (unit being dove on and each immediate adjacent unit), including the ITS gates, to be secured & locked-out/tagged-out during dive operations. Depending upon the time of year, river flows and levels have dictated that additional main units may need to be secured and locked-out/tagged-out to ensure the dive location is not only safe but efficient for the divers to work in.

e.            The operating project will provide the gantry crane and operation of gantry crane for installation and removal of the main unit trashracks. The contractor will be required additional mobile crane (90 ton possibly) for station service trashrack installation and other purposes.

f.             The existing trash rack paint is likely contains lead. The Contractor is responsible to perform lead abatement or to dispose in an approved site.

4.            Questions for Industry:

a.            Is there anything in our SOW that would discourage you from bidding?

b.            Is there anything in our SOW that would cause enhanced pricing uncertainty?

c.            Are there any concerns with schedule or project specific constraints?

d.            Are there any market conditions or industry practices that you feel the government needs to be aware of?

e.            What are the best means of clearing the debris and sediment to allow for access to the track racks for replacement?

f.             What kind of equipment and methodology would be used to move/remove the sediment and debris?

g.            What would be the approximate cost difference of removing debris versus moving debris upstream?

h.            What construction sequence would be utilized for this work?

i.             Approximately how long will it take to fabricate 162 trashracks?

j.             Space onsite is limited. Is it cost prohibitive to store the 162 trashracks off-site prior to installation?

k.            Is there interest amongst contractors to perform the scope of work under one contract or would the trashrack scope and debris scope need to be separate contracts?
