PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: This project is located in Voyageurs National Park, the current vault toilet locations:

Forest Overlook, Beaver Pond Overlook, Kabetogama Boat Launch and Ash River Boat Launch. There is currently 3 single user vault toilets and 1 Double user located on sites. The Park will be removing the vaults and buildings before this contractor’s work begins. The contractor on this project is responsible for preparing the site for the installation of three (3) new, single user precast concrete Buildings (comfort station), and precast concrete septic tanks and one (1) new, double user precast concrete Building (comfort station) and precast concrete septic tank. They must tie into existing walkways, pathways and or landings by fine graded to establish positive drainage away from newly installed unit and to eliminate tripping hazards.

1.2 Work Covered by the Contract Documents:

A. Project Location: Voyageurs National Park, 9759 Meadwood Road, Orr Mn 55771

B. Work consists of: Installing (4) pre-casted concrete toilet Buildings (CXT -Cascadian Unit or NPS approved equivalent) comfort stations and (4) pre-cast concrete septic vault tanks. The comfort stations are all located in the Kabetogama and Ash River Areas. All comfort stations are on mainland and contractor will be able to drive to these locations. The 4 sites are the Ash River Boat Launch, Kabetogama Boat Launch, Beaver Pond Overlook Trailhead and the Meadwood Day Use Area. All comfort station areas currently have stick built comfort stations located on site, the park will be responsible for the removal of the current structures and vault tanks. The contractor will be responsible for all site prep, excavation, purchasing, delivery and installing the new vault tanks and comfort stations, connecting the new precast comfort stations to the vault tanks, final grading, clean up and getting all materials to each site. All sites will require a crane to lift and set the comfort stations in place with out the removal of trees in the area unless necessary. The Ash River Boat Launch comfort station will be the double sided precast comfort station, this comfort station is located 66 feet from the asphalt pavement with a 6 foot wide trail

Page | 3 leading to it. The Beaver Pond Overlook site will be a single sided precast comfort station and is located 106 feet from the asphalt pavement with a 6 foot wide trail leading to it and heavily treed around it. The Meadwood Day Use area comfort station is single sided precast comfort station and is located 42 feet from the asphalt pavement with a 6 foot wide trail leading to it and heavily treed around it. The Kabetogama Boat Launch comfort station is single sided precast comfort station and is located 10’ feet from the asphalt pavement with a 6 foot wide trail leading to it.

INSTALLATION

A. Scope of Work

Finished floor elevation should be 4-6 inches above natural grade measured at the front entrance of the floor. Both the floor and the top of the vault should be above the surrounding ground level with the pathway sloped up to meet the entryway. Ideally, the back of the building should be slightly higher (up to but not exceeding 2% slope in any direction) to allow water to freely drain out of the toilet rooms.

3. The hole dug to accommodate the vaults must be large enough to be workable and to allow the floor to the building to fit on the vaults when placed, but small enough to avoid excessive backfill after placement.

B. Materials

1. Bedding material to be 3/8” minus crushed or screened aggregate.
