Our Construction Group

The construction lawyers at JSS Barristers offer a full range of services to the construction industry. We are regularly involved with owners, contractors, developers, construction professionals, trades and suppliers. We routinely act in courts across Western Canada, and in arbitrations, mediations, and negotiations, to resolve construction disputes of all kinds. We are often retained as counsel, but given the prevalence of alternative dispute resolution in the construction field, some of our lawyers are also appointed as arbitrator or mediator.



Construction disputes commonly involve significant stakes. Regardless of how large the amount in dispute might be, whether a resolution is satisfactory will depend not just on the ultimate outcome, but also on the time and cost incurred through the dispute process. Given that construction disputes often involve numerous parties, complex technical issues, and voluminous project records, experience is necessary for the efficient and effective management of construction disputes. Our construction lawyers have a wealth of experience and knowledge that we bring and apply to construction disputes, which allows us to focus on the real issues and achieve cost-effective results.

In some instances, the best outcome must take into account a variety of factors, including any larger and long-term valuable relationships, the relative costs and benefits of particular disputes or issues within a dispute, and the importance of the principles and reputations involved. We actively explore and listen to our clients' goals for the direct and indirect considerations at play, and then take those goals into account in how we assertively advocate our clients' positions.

  • Represented a leading architectural firm against whom a claim was made by the owners of one of Calgary's iconic buildings as a result of alleged cost over-runs. The matter was ultimately resolved through a negotiated settlement.
