Construction Law in Calgary and Alberta
Construction law in Alberta governs the relationships between property owners, developers, contractors, subcontractors, suppliers, and consultants involved in building projects. These relationships are typically defined through detailed construction contracts and are further regulated by legislation such as Alberta’s Prompt Payment and the Construction Lien Act.
Construction disputes can arise at any stage of a project, including during contract negotiation, project execution, payment cycles, or after project completion. Issues such as delays, deficiencies, scope changes, and payment disputes can quickly escalate if not addressed effectively.
Our Calgary construction lawyers help clients understand their legal rights and obligations while developing strategies to resolve disputes efficiently and minimize disruption to ongoing projects.

Construction Disputes and Litigation
Construction disputes can arise from a wide range of issues, including delays, defective work, contract interpretation, or project management conflicts. These disputes may involve multiple parties and significant financial stakes.
Our firm represents clients in construction disputes involving:
- Breach of construction contracts;
- Project delays and delay claims;
- Deficiencies and construction defects;
- Cost overruns and change order disputes; and
- Contractor and subcontractor conflicts.
While many disputes can be resolved through negotiation or mediation, our team works closely with clients to resolve disputes efficiently and, where necessary, collaborates with our civil litigation lawyers in Calgary for court proceedings

Construction Contract Review and Drafting
Clear and well-structured contracts are essential for successful construction projects. A carefully drafted agreement can prevent disputes, allocate risk appropriately, and clarify expectations among project stakeholders.
Our construction law services include:
- Drafting construction agreements
- Reviewing contractor and subcontractor contracts
- Negotiating contract terms and dispute clauses
- Addressing change orders and scope modifications
By ensuring that contracts are legally sound and clearly structured, we help clients reduce the risk of costly disputes later in the project lifecycle.

Builders’ Liens and Payment Disputes
Payment disputes are among the most common issues in construction law. Contractors, subcontractors, and suppliers may have legal rights to file a builder’s lien when payment for services or materials has not been received.
Under Alberta’s Prompt Payment and Construction Lien Act, strict timelines apply when filing or responding to liens. Missing these deadlines can significantly affect a party’s legal rights.
Our Calgary construction lawyers assist with:
- Filing builders’ liens;
- Defending against lien claims;
- Lien removal and discharge;
- Payment disputes between contractors and subcontractors; and
- Enforcement of lien rights by commencing a Statement of Claim and registering a CLP.
We provide clear guidance on protecting your legal position while working toward efficient resolution of payment conflicts.

Risk Management for Construction Projects
Proactive legal guidance can often prevent disputes before they arise. Our Calgary construction lawyers work with businesses and project stakeholders to identify risks early and develop strategies that protect both legal and financial interests.
This may include:
- Contract structuring and risk allocation;
- Compliance with construction regulations;
- Advice during project disputes; and
- Strategic guidance during complex negotiations.
By addressing legal risks early in the project process, we help clients maintain project stability and avoid costly disruptions

Alternative Dispute Resolution in Construction Matters
Construction disputes are often well-suited to alternative dispute resolution methods such as mediation or arbitration. These approaches can provide faster and more cost-effective outcomes than traditional litigation.
Our team assists clients with:
- Construction mediation;
- Arbitration proceedings;
- Negotiated settlements; and
- Strategic dispute resolution planning.
We focus on achieving practical outcomes that allow projects and business relationships to move forward whenever possible.
