Notice Description

  Project: tender_10786 - Dogpaw Lake Dam Stop Log Replacement

Detailed Description

The Dogpaw Lake Dam is in the district of Kenora and is located approximately 58 km (36 miles) south east of the town of Kenora, Ontario. The dam is located at the outlet of Dogpaw Lake and controls water level for recreation, fire and flood protection purposes. Flow from the dam discharges directly into Regina Bay which is located on the eastern shore of Lake of the Woods.

The reinforced concrete dam was constructed in 1959 by the Department of Public Works and is currently owned and operated by the Ministry of Natural Resources and Forestry. The structure is approximately 8.2 m high and drains an area of approximately 2004 km2 (787 mi2). Dogpaw Lake has a surface area of approximately 58.7 km2, and a storage volume of 358 x 106 m3. As such, the dam is classified as having a large impoundment. The discharge facility of the dam consists of six 4.27 m (14 ft) wide stoplog controlled sluiceways. Each sluiceway bay can accommodate up to thirteen 300 mm (12 in.) high timber stoplogs. These logs are currently removed and replaced using truck mounted hydraulic boom hoist.

In 2012 an underwater inspection was conducted and determined that the existing lower stop logs are in poor condition and require replacement.

Scope of Work
Dogpaw Lake Dam is located at; UTM: Zone 15 5472519 N 430945 E

The purpose of this project is to replace the existing stoplogs with new ones. The contractor is required to pick-up the new stop logs from the back of the Kenora District office located at 808 Robertson St, Kenora, ON. There will be 18–15’-2”x24”x10” steel stop logs, 6–15’-2”x24”x10” timber stop logs and 24–15’-2”x12”x10” timber stop logs. The MNRF does not have loading equipment at this site, so it is the contractor’s responsibility to load the stop logs.

The contractor is responsible for shipping the stop logs to site.

Contractor to procure a Professional Engineer to design (and seal) a temporary bulkhead for dewatering of bays prior to removal of existing stop logs.

Contractor to determine how they will be performing the stop log exchange. (i.e. working from barge, reconfiguring jersey barriers to work from deck).

The contractor is to remove all 72 stop logs from the 6 bays of the dam and replace with the new stop logs. Removal and replacement of stop logs will be 1 bay at a time and performed in a timely manner. Logs are to be jacked into final position to ensure a tight seal.

When lifting old stop logs and/or dropping new logs, the contractor shall temporarily close the bridge deck (MAXIMUM TIME 5 Minutes) to traffic and pedestrians. Contractor to provide flaggers during operations. Operations to cease immediately if emergency vehicles need access across bridge deck.
