Specifications

Specifications include, but are not limited to:OBJECTIVES1 Determine the condition and remaining useful service life of the concrete buttressesto which the side seal plates are attached, and the condition and remaining usefulservice life of the original grout fill. While grout fill will be removed for Flood Gate#2 repairs, the condition of the grout on the remaining gates may be sufficient toleave it in place2 Determine the extent to which the buttresses, reinforcing steel, steel embedmentsand anchorage for the side seal plates at Flood Gate #2 have deteriorated, and ifthose elements can be reused or must be removed3 Determine the means to temporarily (during the placement of the grout fillreplacement) and permanently anchor the replacement side seal plates to thebuttresses4 Using Lidar or similar precision measurement technology, determine the precisegeometry of the buttress walls that support the Flood Gate #2 side seal plates sothat the temporary and permanent anchorage and plate placement can be designedand constructed to the required tolerances5 Obtain construction plans for use byBRAs staff, and technical guidance fromdesigner during repair to concrete and installation of the new side seal plates forFlood Gate #26 Obtain design engineers opinion of conceptual changes to the Flood Gate #2construction plans when considering repairs to the other Flood Gate Side SealPlatesThe BRA requires the services of a professional engineering firm to assess the structuralcondition of the buttresses, reinforcing steel, side seal plate anchorage, and grout at FloodGate #2, and to design the replacement of the side seal plates.
