The Aird & Berlis Construction Group represents clients on the full range of construction-related activities, from tendering, bidding, contract creation and defining relationships with consultants, to providing day-to-day legal resources during design and construction, to litigation and alternative dispute resolution. Construction and development agreements are the core of any project. Our focus is on assisting clients in cost and risk management through the negotiation of contractual relationships. Our mandates include construction projects of all manner of industries, including transportation, infrastructure, health, entertainment, manufacturing, residential and commercial real estate, energy, natural resources, education and non-profit housing.

Aird & Berlis has extensive experience with conventional and alternative financing projects, as well as a broad range of experience with engineering, architect, procurement and construction contracts. We frequently advise clients on issues relating to sustainable design and construction, as well as LEED issues. We also have extensive experience advising clients on insurance requirements, surety and bonds.

If issues arise with a construction contract or any other aspect of a project, we act quickly to minimize the loss of time and money. Our extensive experience and reputation in the field facilitate the resolution of issues without sacrificing the ongoing relationships between the parties. Whether related to constructions liens, delays or design issues, we act for our clients in the court system as well as through alternative dispute resolution, such as mediation and commercial arbitration.

We have extensive expertise in construction liens, and served on the Attorney General’s Advisory Committee on the creation of the Construction Act. We ensure that any liens registered on properties and lien actions are handled in a time-efficient, cost-effective manner. We also have experience with adjudications and the prompt payment processes established under the Construction Act.

Our multi-disciplinary team of experts practise in the areas of real estate, litigation, infrastructure, and municipal and land use planning.
