This project consisted of: Civil Engineering, Engineers, Geotechnical, Structural Engineering

In 2015, TULLOCH was contacted by PCL Constructors Canada Inc. to provide engineering services for the design of the foundation systems for the proposed Photovoltaic (PV) Array Paneling System for a 10MW solar facility in Alfred, Ontario.  The contractor had previously spent numerous man hours on two separate occasions with a design team trying to develop a feasible foundation solution at the site. TULLOCH was brought in for its extensive knowledge base in the solar industry and particularly the anchorage type for these foundations.

TULLOCH mobilized to site within two weeks of being given the authorization to proceed, with a selection of foundation sizes in hand, and spent six days conducting full scale pre-design foundation pile load tests. TULLOCH provided a complete foundation  design report, testing results and design drawings for the PV foundation two weeks after the completion of the field program.

TULLOCH’s quick response and proposed anchorage solution allowed the contractor to move forward with construction and minimized any previously accumulated delays due to unsuccessful foundation design attempts.  The ~5000 foundations for the 10 MW facility were installed in approximately two months (June – August 2015), during which TULLOCH provided timely onsite production proof testing and general conformance reviews of the foundations to verify the installation was in accordance with the design drawings and provide final sign-offs for the PV foundation systems as part of the requirements in the EPC contract documents.
