5P300-16-5238/A - EDMONDS LOCK 25 WEIR AND OVERFLOW DAM HERITAGE STONE MASONRY REHABILITATION (5P300-16-5238/A)

TITLE:

EDMONDS LOCK 25 WEIR AND OVERFLOW DAM HERITAGE STONE MASONRY REHABILITATION

DESCRIPTION OF WORK:

The work consists of the rehabilitation of the heritage stone masonry lock and overflow dam constructed in 1830 at Edmonds Lockstation on the Rideau Canal near Smiths Falls, ON.

Lock rehabilitation work includes deep re-pointing of all masonry joints with heritage lime based mortar, low pressure grouting, and isolated stone repair and replacement. The dry stack stone overflow dam will receive isolated stone replacement. The crest will be pointed and a thin concrete cap poured. New stone must be carefully sourced by the Contractor.

Civil works consist of reconstruction of a dry stack heritage stone retaining wall, re-profiling of an earth dam crest, minor tree and stump removal and construction of new short gravel access lane. The in-water dam safety boom will be modified requiring additional boom floats, chain and pre-cast concrete in-water anchors installed from a barge.

Cofferdams are required for the work. Sequencing is of key importance to maintain flow at the dam. While some work can begin immediately, work on the lock cannot commence until the closure of the Rideau Canal navigation season. Work will extend into winter conditions requiring cold weather masonry considerations. Timely completion is imperative to satisfy fish spawning and spring freshet requirements and to ensure the lock is complete for spring 2017 navigation season opening.
