Who we help
Engineering consultancies are where project risk is allocated to. Principals, builders and head consultants push down warranties, indemnities and design responsibility through consultancy agreements, sub-consultancy agreements and novation deeds. Registration regimes in several states now attach personal accountability to certifications and sign-offs. Professional indemnity insurance is expensive and conditional on not accepting liabilities beyond the standard of care.
Beyond the project documents, consultancies face the same commercial issues as any professional services business: fee recovery, ownership of models and reports, staff moving between firms with client relationships, partner succession and structuring for growth or sale. These issues compound when a firm is working across civil, structural, mechanical, electrical, environmental and fire safety disciplines with different regulatory overlays.
Envision Legal acts for engineering consultancies on standard terms, negotiation of client and head-consultant agreements, novation, liability and insurance alignment, sub-consultant arrangements, intellectual property, employment and restraints, practice structures and transactions. This page focuses on the commercial side; construction litigation and expert-witness work are referred where appropriate.

Common legal issues
Situations we are usually brought in on
“A head consultant issues a sub-consultancy agreement passing through the principal's entire risk allocation.”
Back-to-back terms are common, but you should see the head agreement and negotiate caps and exclusions proportionate to your fee and discipline, rather than absorbing the head consultant's full exposure.
“A builder asks for a design compliance certificate broader than your scope.”
Certificates should match the services actually performed and the documents actually reviewed. Broad declarations create personal and professional exposure, particularly under design practitioner registration regimes.
“A client withholds the final 30 per cent of fees citing delays caused by others.”
Fee recovery depends on the payment terms, whether security of payment legislation applies to your services, and what the agreement says about delay. Structured recovery is usually possible.
“You want to tender as a consortium with two other consultancies.”
A teaming or consortium agreement should set out roles, liability sharing, IP, exclusivity and what happens if the tender is won or lost, before the submission is lodged.
“A senior engineer departs and takes a project team to a competitor.”
Restraints, confidentiality and non-solicitation of staff and clients in the employment contracts determine your options. Without them, the practice is relying on general duties.
“You are approached by a larger firm to acquire the consultancy.”
Structure, earn-outs tied to project pipeline, retention of key staff, treatment of run-off PI cover and existing project liabilities all need to be dealt with in the transaction documents.

FAQs
- What liability terms should engineering consultancies push back on?
- Fitness-for-purpose warranties, indemnities not limited to your negligence, uncapped liability, liability for consequential loss, and obligations to comply with all laws or the principal's requirements regardless of your scope. Each of these can fall outside PI cover and should be negotiated to reasonable skill and care, proportionate liability and a sensible cap.
- Does security of payment legislation apply to engineering consultancies?
- In most states, yes — consultancy services related to construction work are covered, which gives access to the payment claim and adjudication process. The details differ by jurisdiction and the process has strict timeframes.
- Who owns the engineering models and calculations?
- The consultancy, unless the agreement assigns them. A licence to the client for the project is the usual position, and it can be conditional on payment. Reuse of know-how and generic details should be preserved expressly.
- What should a teaming agreement for a tender cover?
- Roles and scope split, exclusivity during the tender, cost sharing, IP in the submission, liability allocation if successful, the form of the downstream agreement, and what happens if one party withdraws or the client wants a different structure.
- Are restraints on senior engineers enforceable?
- Reasonable restraints protecting legitimate interests — client relationships, confidential information, team stability — can be enforced for a limited period and area. Broad non-competes are less likely to be upheld. The drafting and the seniority of the engineer both matter.
- Do you act on construction litigation or as expert counsel?
- We handle negotiation, fee disputes and early dispute resolution. Large construction litigation and expert-witness matters are referred to specialists, usually coordinated with your PI insurer.
- How do you charge engineering consultancies?
- Fixed fees for standard terms, agreement reviews, novation and sub-consultant documents once we understand the scope. Firms that need continuous support use a fractional general counsel arrangement.
