Construction and Engineering Dispute Resolution Procedures
Our solicitors are skilled in using a variety of methods and procedures to resolve your dispute.
These procedures include binding (either on a permanent or temporary basis) proceedings such as adjudication, litigation, arbitration and expert determination. They also include non-binding procedures such as mediation and early neutral evaluation. Each of these procedures is considered below.
Adjudication
Adjudication is a dispute resolution peculiar to the construction and engineering industries. Either party may, but is not obliged to, refer a dispute to adjudication.
Adjudication is a speedy process in which the adjudicator produces a binding but temporary decision within 28 days. The decision is enforceable in the High Court on a summary judgment basis. Either party can then, if they wish, refer the matters decided in the adjudication to the dispute resolution procedures outlined in the contract. In short, adjudication applies a “pay now, argue later” approach.
We act on behalf of both referring parties (claimants) and responding parties (defendants) in adjudication proceedings, marshalling the evidence, preparing statements of your case, liaising with expert witnesses, the other party and the adjudicator and representing you at any meetings with the adjudicator.
Arbitration
Some construction and engineering contracts provide for disputes arising under the contract to be referred to arbitration.
Arbitration is a formal process akin to litigation but is private to the parties. The decision of the arbitrator is binding but subject to appeal in certain circumstances.
We act on behalf of both claimants and defendants in arbitration proceedings, marshalling the evidence, instructing Counsel, liaising with expert witnesses, the other party and the arbitrator and appearing at arbitration hearings, including the full hearing.
Early Neutral Evaluation
An independent expert will make an objective non-binding assessment of the strengths and weaknesses of each side’s case. This will give you a realistic idea of how you may fare in litigation, encouraging a swift settlement before you reach that stage in the process.
We act on behalf of both parties in early neutral evaluation, marshalling the evidence, preparing your position statement, liaising with expert witnesses, the other party and the independent expert and appearing at any hearing.
Expert Determination
Some construction and engineering contracts provide for and the parties can agree to a dispute being determined by an expert.
Expert determination shares similarities to adjudication as to the speed of the process. However, the determination of the expert is generally binding on the parties.
We act on behalf of both referring parties (claimants) and responding parties (defendants) in expert determination, marshalling the evidence, liaising with expert witnesses, the other party and the expert and appearing at any hearings.
Litigation – Court Proceedings
In the absence of an arbitration clause, litigation in court is the default mechanism for the resolution of disputes. Construction and engineering disputes generally proceed in the specialist Technology and Construction Court.
The decision of the judge is binding but subject to appeal in certain circumstances.
We act on behalf of both claimants and defendants in litigation proceedings, dealing with the pre-action protocol for construction and engineering disputes, marshalling the evidence, instructing Counsel, liaising with expert witnesses, the other party and the court and appearing at court hearings, including the trial.
Mediation
Mediation is a voluntary process where the parties, with the assistance of an independent third party mediator, seek to resolve disputes through discussion and negotiation.
A mediation is a non-binding process although any agreement reached at the mediation will be confirmed in writing and be binding upon the parties.
Proceedings at a mediation are without prejudice and cannot be referred to in any subsequent formal proceedings.
We act on behalf of both parties (claimants and defendants) in mediation, marshalling the evidence, preparing your position statement, liaising with expert witnesses, the other party and the mediator and appearing at the mediation.
