Following the successful completion of BAUER’s part of the project, I would like to express my appreciation for the means and methods in which BAUER has performed on the project.

The flexibility and understanding that BAUER afforded us in a very difficult time was much appreciated. Furthermore, delivering on time with an exemplary safety record is a testament to Bauer's professionalism.
The professional way in which the BAUER team prepared and executed the works was very well received. Trial mixes and generally quality management and control along the detailed method statement secured the highest standards of quality for the product.

Daniel Cuartero, Project Director, Peace River Hydro Partners (PRHP), about the SITE C Project – Execution of Single Phase Cut-off Wall
Following the successful completion of BAUER’s part of the project, Peace River Hydro Partners would like to express its appreciation for the means and methods in which BAUER has performed on the project.
Details of the Contract execution period: August 2016 to November 2017. In order to meet the specified construction schedule, the cut-off wall works had to be executed through the winter months facing the harsh winter conditions of Northern Canada. Temperatures during wall installation were as low as - 25° Celsius (lower than -30° Celsius when considering the wind chill) and this has required a special winterization set-up for the mixing plants as well as the slurry lines.
The work carried out in constructing the cement-bentonite cut-off walls in Canada was very professional. BAUER proactively was seeking solutions and correcting problems and were answering questions related to any subjects of the works. I also note that the matters were few and infrequent.
BAUER’s professional approach towards Health Safety Environment (HSE) was excellent. The project was executed within the agreed schedule.
