PART 1

GENERAL INFORMATION

1. General:

This is a services contract to inspect and clean/flush the outlet works stilling basin shale drains at Oahe Dam, north of Pierre, South Dakota.

1.1 Description of Services/Introduction:

The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to clean by hydro-flushing the outlet works shale drains as defined in this Performance Work Statement (PWS), except for those items specified as vernment furnished property and services. The contractor shall perform to the standards in this contract.

1.2 Background:

Flood control outlet works are located on the river’s right bank and consists of six tunnels with individual submerged intakes, dam-center control shafts, a two stage stilling basin, and a discharge channel (Photo 1). The outlet works is used to control releases from the reservoir in conjunction with releases required for power generation and were originally used to divert the river during construction. At the maximum

In fo rm at io n operating pool of elevation 1620.0 feet, the outlet works has a discharge capacity of 111,000 cfs. The stilling basin, located approximately 1,800 feet downstream from the dam’s axis, conveys water to the discharge channel. The stilling basin structure is approximately 495 feet wide and extends 483 feet downstream from the tunnel portals (Plate 1). The stilling basin is a two stage type consisting of primary and secondary basins separated by an ogee weir. The 6 concrete tunnels are 18 feet in diameter and numbered 1 through 6 (from the riverside to the abutment side). The invert of the tunnels is at elevation 1420.0 feet. Five training piers guide water flow from the tunnel portal transition sections, down the drop section and into the primary basin.

Access to the outlet works shale drains is accomplished by entering the access manholes that are located on the west side of each tunnel (Plate 1 and Photo 2). Tunnel 1 has a manhole on the east side that is used for accessing piezometers that are not included in this work. The manhole access with covers are rectangle shaped, 2’-0” by 3’-0”, at elevation 1445.0 feet. The manholes are 6 feet by 6 feet square. From the manhole cover, there is a ladder to a landing at elevation 1431.0 feet, where there is a valve stem that operates a valve at elevation 1422.0 feet, used to drain the manhole (tunnels 2-5). There is another ladder from the landing to the bottom of the manhole at elevation 1418.0 feet. The bottom of the manhole is slightly sloped to a sump and is non-slip (Plates 2 and 3, and Photos 3 through 7).

The shale drains discharge into the manhole from the upstream wall at approximate elevation 1424.0 feet (Plate 4, Photos 8 and 9). Each manhole (tunnels 1-5) has one drain discharge visible. Tunnel 6 is unique in that it has five drain lines entering the manhole, and two ~12” diameter headers on the downstream side. One header is covered with a flange as shown in the drawings and can be seen in Photos 10 and 11.

The lower header in tunnel 6 drains the manhole and extends down the right tailrace wall to the access pit located adjacent to the weir. There is no discharge valve in tunnel 6 manhole; the valve is in the valve pit. Normal tail water elevation is approximately

1425.0 feet, so each manhole is expected to need dewatering after the valves are closed.

According to the drawing on Plate 4, it appears there are two shale drains that join in the upstream wall and discharge through one discharge pipe. These two drains are oriented in the same direction upstream, but at different angles from the horizontal. One pipe is angled approximately 2˚ upward (looking upstream) from horizontal, while the other is angled approximately 9˚ downward (looking upstream) from horizontal, as shown in Plate 4. However, as a result of an initial camera investigation done by the Lake Oahe project office, it is believed only the 2˚ upward (looking upstream) from horizontal drain actually exist. Reference plan view in drawing Plate 5, which only shows one drain extending upstream into the shale. The base contract calls for hydro-flushing and inspecting the drains angled approximately 2˚ upward (looking upstream) from horizontal in tunnels 1 through 5 and the one drain in tunnel 6 that is oriented upstream along tunnel 6. Option #1 calls for hydro-flushing and inspecting the four drains in tunnel six that radiate out form the manhole towards the right abutment. If other drains are found during the inspection it shall be documented within appropriate deliverables described in Section 1.4.

1.2.1 Project General Information:

Oahe Dam and Reservoir, one of six main stem dam projects on the Missouri River, is located in central South Dakota, approximately six miles upstream from Pierre, South Dakota in Hughes and Stanley Counties. Oahe Dam consists of an earthfill embankment, a gated concrete spillway structure with an earthcut spillway channel, a hydroelectric generating plant, flood control outlet works and a multi-purpose reservoir operated as a unit in coordination with five other mainstem dams. The mainstem system operates according to a comprehensive plan for flood control, irrigation, navigation, power development, recreation, and other uses in the Missouri River Basin.

5. Specific Tasks:

5.1 Basic Services:

The contractor shall provide services to clean by hydro-flushing and inspect drains with camera equipment and produce a detailed formal report to thoroughly document the condition of these features and results of cleaning procedure. Deliverables from this work will include DVD(s) of the inspection footage and a report that summarizes the procedures and findings of all inspections and includes individual inspection logs that summarize the condition of each shale drain segment and documents the location of any significant observation.

Basic and optional work is listed below. Complete task descriptions, site-specific requirements, and other pertinent information for the Oahe Dam are provided below.

5.1.1 Base Contract:

Clean by hydro-flushing and inspecting up to approximately 3,800 lineal feet of shale drain (horizontal to 2˚ upward looking upstream) in the outlet works stilling basin.

5.1.2 Option 1:

Clean by hydro-flushing and inspecting up to approximately 2,500 lineal feet of shale drain (angled 2˚ upward looking upstream) in the outlet works stilling basin.

5.2 Base Contract – Clean by Hydro-Flushing and Inspect Drains Horizontal to 2° Upward Looking Upstream:

This work shall include hydro-flushing, performing a camera inspection and documenting the condition of up to 3,800 lineal foot of horizontal to 2˚ upward (from horizontal) 2 inch drain pipe accessed from the outlet works stilling basin manholes.

The contractor shall conduct up to two hydro-flush tests and perform camera inspections both before and after the test hydro-flush. The test pipe sections shall be a minimum of 20 feet in length with locations to be selected by the COR. During the test hydro flushing, the water pressure used shall be documented by the contractor. The condition of the test pipe section shall be documented by the contractor both before and after the test hydro-flush. Results documenting the condition of the test pipe sections shall be reviewed and approval given by the COR prior to the contractor proceeding to hydro-flushing all the drain pipes outlined in the base contract.

All hydro-flushing and inspection equipment and procedures for this work shall conform to this PWS and hydro flushing and inspections shall be inclusive of the estimated pipe length for pipes identified in Table 5-1 below, if accessible. Pipe and manhole details for the stilling basin drains are provided on drawing PLATES 1-5. Manhole designations, pipe lengths and pipe materials are summarized below in Table 5-1. NOTE: Pipe lengths were approximated from PLATE 5. All materials flushed from the drains must be captured and removed from the manholes. The Contractor’s Work Plan shall discuss their method to prevent sediment from washing into the legs of the drains that are not t 5

T scheduled for flushing. Disposal of the sediments will be coordinated with and directed by the Project POC.

The COR shall be notified immediately if any portion of pipe cannot be hydro-flushed and/or inspected, and details shall be documented on the Daily Log. Payment will not be made for drain pipe portions not hydro-flushed or inspected without prior approval from the COR.
