SUBJECT: Preconstruction Documents for Vehicle Maintenance BuildingEielson Air Force Base, Alaska

PROJECT: ANC30768.DO.60

Please find attached the following documents pertaining to the ongoing assessment ofthe construction site adjacent to the Vehicle Maintenance Building:

Attachment 1 Table of analytical data obtained by CH22M HILL duringthe field activities of January 23 through January 301, 1991.

Attachment 2 Graphic presentations of results obtained by the Corps ofEngineers in 1989 and by CH2M HILL in 1991.

Attachment 3 Boring logs from field activities conducted by CH-"MHILL in January 1991.

Attachment 4 TCLP results for soils collected in January 1991.

As the graphic presentations indicate, the results obtained this year by CH2M HILLdo not correlate with the results obtained1 by the Corps of Engineers (COE) 2 year-sarko. Subsequently, CH2M I-{TL does not agree with the COB recommendationmade in 1989 for soil excavation at the construction site. Based on the infcrmationreviewed or obtained by CH2M HILL, construction wrill no: impact ongoing or futureinvestigation or remnediation at the Vehicle Maintenance Building.

The information presented in the attachments will be necessary for the contractorswho receive the RFP for construction to prepare an adequate Health alnd Safe--v Planfor site work. Additionally, the contractors who submit bids to the Air Force fo r thisawork must provide the plans and related costs for storage, analysis, and disposal ofVsoil excavated for construrtio;, purposes. If dewatering is necessarx durinz construc-tion, a plan for water manLgement should also be provided to the Air Force. Thisplan should include storage, analysis, and disposal. The requirements for the

contractor's Heaith and Safety Plan and soil/water management plans must be incor-porated into the specifications within the bidding documents to be sent out onApril 1, 1991, by the Air Force.
