About this file

This document contains engineering drawings and specifications for the reconstruction of Reser Dam in Montana. Key details include plans for a new outlet works consisting of a 30-inch reinforced concrete pipe and 18-inch high-density polyethylene pipe supported by concrete blocks. Additional drawings show designs for a spillway tower, trash rack, inlet structure, sluice gate, and gate pedestal. Specifications are provided for boat ramp concrete blocks, spawning bed gravel materials, and boulders for fish structures. Construction notes outline requirements for site work including spawning beds, fish structures, the boat ramp, an access channel excavation, and access trails. The related federal contract opportunity is solicitation number 140L0621R0024 from the Department of the Interior Bureau of Land Management for the Reser Dam reconstruction project.

BASIS OF SURVEY DATUM

This project was surveyed on the Montana State Plane Zone 2500 Coordinate System using RTK GPS. The project was brought to ground at survey control point CP-1 and transformed to a local coordinate system. The geodetic datum is NAD83(CONUS). The vertical datum is NAVD 88 (GEOID12B). Horizontal units are International Feet. Vertical units are US Survey Feet.

Project control was established by OPUS Position at point 1. Values for Points 2-4 were determined by redundant RTK GPS observations from Point 1.

BOAT RAMP PROFILE

BOAT RAMP SECTION

Material Specifications

· Boat Ramp Concrete Blocks - Use a fabricated concrete block mat for the boat ramp surfacing.

The concrete block mat shall be Flexamat or approved equal. Use nonwoven geotextile fabric for the block underlayment. Submit concrete block mat data and shop drawings for approval.

· Spawning Bed Gravel - Provide gravel materials from off-site sources consisting of reasonably well-graded sand and gravel blend conforming to the gradation listed below. Submit gravel source and gradation testing for approval.

Fish Structure Rock - Boulders provided from an offsite source shall be dense, angular, sound rock fragments resistant to abrasion, free of cracks, seams, clay, organic material and defects that would hasten degradation by water and/or frost action. Furnish stone conforming to the property specifications in Section 02275 and to the gradation listed below. Submit rock source and test results for approval.

General Construction Notes

· Spawning beds - Bed locations and dimensions are to be field directed. The spawning bed subgrade shall be compacted. Perform the subgrade compaction with four passes of a loaded wheel loader or approved alternate method. Place and spread gravel to a finished thickness of 1 foot. Do not compact spawning bed gravel.

· Fish structures - Rock pile locations and dimensions to be field directed. Fish structures will generally consist of fish structure rock placed in an approximate 10-foot diameter by 3-foot high cone shape.

· Boat ramp - The boat ramp location to be field directed. Over-excavate boat ramp subgrade 6 inches and compact with four passes of a loaded wheel loader or approved alternate method.

Infill between boat ramp blocks with road gravel.

· Access Channel Excavation - The location of the access channel excavation through the right side of the original dam will be field directed. Excavation location is approximately 800 feet northwest of CP-3. Assumed excavation dimensions are 300-feet long, 5-feet wide, and 5-feet deep with maximum side slopes of 2H:1V.

· Access Trails - Access trail locations to be field directed. Maximum slope of access trails will be 10%-15% between elevations 2655 and 2635. Trail width is to be 4 feet to 5 feet. Maximum allowable excavation side slopes are 2H:1V.
