Construction Contract Disputes: How They’re Resolved in BC

What Counts as a Construction Contract Dispute in BC?

A construction contract dispute in BC arises when one party to a construction agreement claims the other has failed to perform a contractual obligation. Common triggers include non-payment, defective workmanship, unauthorized scope changes, project delays, and wrongful contract termination before project completion.

BC construction contracts define the obligations of owners, general contractors, subcontractors, and suppliers on residential, commercial, and infrastructure projects. When any party fails to perform as agreed, the non-breaching party gains the right to seek a legal remedy.

Non-payment is the most frequent trigger for construction dispute proceedings in BC. The Builders Lien Act, RSBC 1996, c 45, gives contractors and subcontractors a statutory right to register a lien against the project property when they are not paid for work or materials. A builders lien preserves a claimant’s payment rights while the underlying dispute proceeds through one of the resolution methods outlined below.

Other common disputes include defective work that fails to meet contract specifications or BC Building Code standards, unpaid change orders following unauthorized scope changes, project delays caused by a party’s failure to perform, disputes over subcontractor performance and supervision, and general contractor liability for deficiencies affecting subsequent trades.

BC construction law applies to both written and verbal agreements. Written contracts reduce the range of disputed facts by defining scope, timelines, and payment terms with precision. Verbal agreements produce disputes more frequently because contractual obligations are harder to document and prove before a tribunal or court.

Our construction contract lawyers in BC handle disputes at every stage, from the first missed payment notice through lien registration, formal dispute proceedings, and BC Supreme Court enforcement.

Negotiation: The First Step in Resolving Construction Disputes

Direct negotiation is the fastest and least costly method for resolving construction disputes in BC. The disputing parties communicate directly, or through legal counsel, to reach a mutually acceptable settlement without courts, mediators, or arbitrators. Most BC construction contracts have a term that requires a formal negotiation step between the parties before any binding resolution process begins.

Negotiation begins with a written notice that identifies the specific contractual breach and the remedy the aggrieved party requires. In BC construction practice, standard Canadian Construction Documents Committee (CCDC) contracts include a dispute resolution ladder that requires parties to attempt formal negotiation within a defined period before proceeding to mediation or arbitration.

Negotiation preserves the working relationship between parties, a factor that carries weight on multi-phase projects where a general contractor and subcontractor remain on site during the dispute period. A negotiated settlement is fully confidential and avoids the administrative costs of third-party proceedings.

Negotiation fails when one party refuses to engage in good faith, when technical evidence such as defect assessments or delay analysis is required to establish liability, or when the amount in dispute is large enough to justify the cost of formal proceedings. In those circumstances, mediation is the next step.

Legal counsel adds value in negotiation by assessing each party’s contractual position and lien filing deadlines before a settlement offer is made, and by drafting settlement agreements that extinguish all claims arising from the dispute.

Construction Mediation in BC

Construction mediation in BC is a voluntary, confidential process where a neutral mediator facilitates negotiation between the disputing parties. Mediation is not binding unless the parties reach a settlement agreement. Most BC construction mediations where both parties participate in good faith produce a settlement, avoiding the cost of arbitration or litigation.

BC construction mediation is governed by the parties’ agreement, which designates the mediator selection process, applicable mediation rules, and confidentiality obligations. Standard CCDC contracts incorporate a mediation step that requires the parties to appoint a mediator within 10 days of a dispute notice and to attempt mediation before proceeding to arbitration.

The mediator does not decide the outcome of the dispute. The mediator’s role is to identify each party’s interests, clarify the disputed facts, and facilitate a settlement that both parties accept voluntarily. Construction mediation in BC typically takes one to three days of structured sessions and costs significantly less than arbitration or BC Supreme Court litigation.

Construction mediation is most effective for disputes involving ongoing contractual relationships, where preserving the business connection between parties has value, and for disputes where the complexity of technical evidence such as building defect assessments would make litigation costs disproportionate to the amount in dispute.

When mediation fails to produce a settlement, the parties proceed to arbitration or BC Supreme Court litigation depending on the dispute resolution clause in their construction contract. ATAC LAW represents construction parties in BC mediation proceedings and prepares clients to present their factual and legal positions effectively.

Construction Arbitration: A Binding Private Process

Construction arbitration in BC is a private hearing process where one or more arbitrators hear evidence from both parties and issue a final, binding decision called an award. Unlike mediation, arbitration produces a result that is enforceable in BC Supreme Court. Parties select an arbitrator with specific construction expertise, and proceedings remain confidential.

BC construction arbitration is conducted under the Arbitration Act, SBC 2020, c 2, and is frequently administered through the BC International Commercial Arbitration Centre (BCICAC), which provides domestic arbitration rules, a roster of experienced construction arbitrators, and procedural administration for BC construction disputes.

The arbitration process mirrors civil litigation in structure: each party produces documentary evidence and witness testimony, and the arbitrator applies BC construction law to the established facts. Arbitration differs from court litigation in three important ways: proceedings are private, the rules of evidence are more flexible, and the arbitrator is selected for construction expertise rather than assigned by the court.

Construction arbitration is appropriate for disputes involving complex technical evidence, disputes where confidentiality is a business priority, and contracts that include mandatory arbitration clauses. Most BC commercial and industrial construction contracts designate arbitration as the binding resolution process following unsuccessful mediation.

An arbitration award is final and binding under the Arbitration Act. Appeals are limited to procedural errors and do not extend to the merits of the dispute. A party who refuses to comply with an award can have the award registered and enforced as a BC Supreme Court judgment. ATAC LAW represents clients through all stages of BC construction arbitration.

Adjudication: BC’s Fast-Track Option for Payment Disputes (Not Yet in Force)

When it comes into force, adjudication under BC’s Construction Prompt Payment Act (SBC 2025, c 24)(the “Act”) gives contractors and subcontractors a mechanism to resolve payment disputes within 30 days. An adjudicator’s decision is interim-binding, meaning the losing party must comply immediately even if the underlying dispute proceeds to arbitration or litigation.

The Act received Royal Assent on November 27, 2025, introducing mandatory payment timelines and a statutory adjudication process to BC’s construction industry. Under the Act, a project owner must pay a general contractor within 28 days of a proper invoice. A general contractor must then pay a subcontractor within 7 days of receiving that payment.

When a payment is disputed or improperly withheld, either party refers the dispute to a qualified adjudicator. The adjudicator issues a decision within 30 days, and the losing party must pay within 15 days of the decision. Adjudication keeps cash flowing on active construction projects without requiring parties to wait for a court or arbitration process that takes months to complete.

Adjudication under the Act is limited to payment disputes. Disputes about defective work quality, project delay liability, contract termination, and professional negligence do not fall within adjudication scope. Those disputes proceed through negotiation, mediation, arbitration, or BC Supreme Court litigation.

When Construction Disputes Go to BC Supreme Court

Construction litigation in BC Supreme Court is the formal judicial process for disputes that cannot resolve through negotiation, mediation, or arbitration. BC Supreme Court has jurisdiction over construction disputes of any value and produces a public judgment enforceable through garnishment, asset seizure, or land registration. The process typically takes 18 to 36 months from filing to trial.

BC Supreme Court construction proceedings are governed by the Supreme Court Civil Rules, BC Reg 168/2009. A claim begins with a Notice of Civil Claim setting out the disputed facts, legal basis for the claim, and remedy sought. The defendant has 21 days to file a Response to Civil Claim. Discovery of documents and examinations for discovery follow, with trial scheduled after all pre-trial steps are complete.

Builders lien enforcement follows a specific litigation pathway. The Builders Lien Act requires a contractor or subcontractor to commence a lien action in BC Supreme Court within one year of registering the lien, or the lien expires and the claimant’s statutory payment rights are lost. BC Supreme Court lien proceedings consolidate all lien claims from a single project and determine the priority of payment from the project property or lien holdback fund.

BC Supreme Court litigation is appropriate for disputes involving lien enforcement, large amounts where the costs of litigation are proportionate, and situations where no arbitration clause exists in the construction contract. The court process is public, which means the judgment becomes part of the public record and can affect the losing party’s business reputation.

Most BC construction disputes that reach formal legal proceedings settle before trial through negotiations between legal counsel. Our construction litigation team represents contractors, subcontractors, owners, and developers in BC Supreme Court construction proceedings, from initial pleadings through trial and post-judgment enforcement.

Choosing the Right Resolution Method for Your Construction Dispute

The best dispute resolution method in BC depends on the type of dispute, the amount at stake, the urgency of resolution, and the parties’ contractual dispute resolution clause. A BC construction lawyer evaluates all five methods and identifies applicable deadlines before recommending a course of action.

Many BC construction disputes move through more than one method in sequence: negotiation fails, mediation is attempted, and arbitration or litigation follows. The Limitation Act, SBC 2012, c 13, sets a two-year limitation period for most construction claims in BC. Builders lien claims carry their own shorter deadlines under the Builders Lien Act. Missing either deadline eliminates the claimant’s right to proceed.

ATAC LAW’s BC construction lawyers advise clients across all five resolution methods and identify the correct deadlines before any proceeding begins. Contact us to assess your dispute resolution options before a lien deadline or limitation period closes your claim.
