Before Anyone Directs the Site: Set a Property Development Instruction Authority

A casual site comment can travel further than intended. “Could we move that wall?” becomes a drawing query, an order, a delay claim or work that nobody remembers approving. The developer may believe it was only a discussion while another party believes it was an instruction.

A capable developer defines instruction authority before work begins. The contract, superintendent or contract administrator, builder, designers and work-health-and-safety duties all matter. A project matrix coordinates the pathway; it does not replace the contract or professional advice.

Use the SIGNAL pathway

1. Source: record who raised the issue and whether it is a request, RFI, safety matter, defect or proposed change.
2. Impact: assess design, approval, cost, time, quality, finance and safety consequences.
3. Gate: identify contractual authority and the approvals required before direction.
4. Notice: issue the instruction through the required formal channel.
5. Audit: link drawings, quotations, decisions and acknowledgement in one register.
6. Loop closure: verify implementation, cost treatment and as-built records.

Australian Government contract guidance recommends defining work, responsibilities, payment, timeframes and dispute processes. Safe Work Australia explains that construction is subject to work health and safety duties, while jurisdictional regulators administer applicable laws. Risk guidance supports named controls and review. Exact instruction rights and safety duties depend on the contracts, role and location.

A clearly labelled hypothetical

During a site walk, an investor asks whether a window can be enlarged. The site manager does not treat the comment as approval. It enters SIGNAL as a request. The designer checks compliance, the builder prices time and cost, the contract administrator confirms the formal pathway, and the authorised party decides. If rejected, the register still closes the request so it cannot resurface as an assumed direction.

Put boundaries around communication

• List who may raise requests and who alone may issue contractual instructions.
• Provide an immediate escalation path for hazards and urgent protective action.
• Make it clear that visitors and investors do not direct trades.
• Require written confirmation where the contract demands it.
• Reconcile the instruction register with variations, programme and forecast cost.

The Think Property Club System separates observation, assessment, approval and instruction. Strategy protects the intended product; Specialists test design, contract and safety impacts; Support helps the team enforce the pathway when pressure encourages shortcuts.

Your next action

Draw your project’s SIGNAL pathway on one page. Name the authorised issuer, cost and design approvers, urgent safety route and system of record. Have the solicitor and contract administrator check it against current documents.

Key Takeaway

Site communication becomes controllable when every comment is classified and only properly assessed, authorised directions become instructions.

Your Turn

If someone made a design request on site tomorrow, could your team show exactly how it becomes approved, rejected or escalated?
