Site work for a civil project in Mayerthorpe, Alberta. Completed plans call for site work for a water / sewer project; and road / highway.

The Government of Alberta (the "Province") requires construction services for the Paddle River Dam flood handling and spillway repairs. The scope of this assignment includes three main design tasks, which are to enhance the spillway stilling basin with the addition of concrete stilling blocks, rehabilitation of the service spillway, and rectification of top of the earthfill dam and clay core. The Site of the Work of this Contract is located at Paddle River Dam, which is located within SW-1-57-8-W5 , approximately 8 km southeast of Mayerthorpe, Alberta and about 110 km WNW of Edmonton, Alberta. The main purpose of the dam is to provide flood control for downstream communities. The impounded reservoir also provides recreation, flow regulation, and a reliable water supply to some downstream communities. The elevation of the service spillway crest (El. 704.25 m) and current reservoir Target Operating Level (TOL; El. 696.8 m) with the highest level on record was El. 705.07 m, occurring in August 1989. The mean daily water level exceeded the crest of the spillway in only three years since the dam was constructed: 1989, 2011, and 2020. The service spillway has not passed any significant flows since its construction. The Project will include, but will not be limited to, the following scope of work: .1 Paddle River Dam Flood Handling and Spillway Repairs : Enhancements to the spillway stilling basin: conversion of the existing USBR Type II stilling basin to a Type III basin by adding concrete baffle blocks. Service spillway fence post and concrete repairs: Removal and replacement of deteriorated and cracked spillway concrete, rehabilitation of deteriorated expansion joints, grout injection of cracks, and replacement of all the existing fence posts and fencing. Replacement of undersized rip rap in the outlet channel immediately downstream of the stilling basin, and expansion of rip rap along the upper shoreline. Rectification of top of the earthfill dam and clay core to address freeboard deficiencies, as required, to allow the dam to safely pass the IDF in accordance with CDA Dam Safety Guidelines. Scope to include raising the impervious fill dam core and the top of dam as required, along with installation of jersey barriers or similar to prevent overtopping by waves. .2 Co-ordinate multiple disciplines including structural and geotechnical. The project delivery method will be Bid-Build. Additional project information can be found in the Appendices. Complete design drawings and technical specifications, which will be included in the Tender, are being developed by the design consultant retained by Transportation and Economic Corridors. The Contractor will construct the Project in accordance with the technical requirements of the Tender and must comply with all applicable national, provincial, and municipal laws, codes, standards, regulations, and by-laws.
