Our 8-Step Action Plan

A structured framework for getting your business through the cost crisis

We developed this framework because construction businesses were coming to us with the same problem and no clear path through it. Each step builds on what the previous step reveals. Work through them in order, or bring your questions to a Strategy Session.

Action Plan

Rising Construction Costs Australia: Our 8-Step Action Plan

Why costs are rising in 2026, how the six main cost drivers interact with your contracts, and a step-by-step framework for assessing your position, recovering what you can and protecting your business.

Read our full 8-Step Action Plan →
1

Calculate actual cost exposure

Project by project. All six cost inputs. Without this number, nothing else is possible.

2

Triage the portfolio

Which projects are critical, which need managing, which need watching.

3

Serve correct notices

Before any other step. Time bars close and valid claims are lost permanently.

4

Prepare your claim

Documented, verifiable, specific. Built from actual cost data, not estimates.

5

Approach your principal

Lead with delivery risk, not contractor hardship.

6

Formalise any agreement

Deed of amendment before the project moves forward.

7

Review your subcontract position

Whether downstream contracts pass cost risk and on what terms.

8

Protect your business

Director obligations, personal exposure, structural decisions under financial stress.

Where the Cost Pressure Is Landing

Six areas where the cost crisis is hitting your business right now

Cost escalation moves through your contracts, your project finances and your business at the same time. Read the articles that apply to your business.

1

Your contracts were priced before 2024 conditions

Every unrecoverable cost increase comes directly off your margin. Most contracts contain no effective escalation mechanism. The question is whether yours is one of the exceptions, and what you can do if it is not.

Read: fixed-price contracts and cost increases →
2

Your rise and fall clause is not recovering what you expected

Most Australian escalation clauses calculate against a price index that moves slower than actual costs. Caps and base date limitations often reduce what you recover to well below what you have spent.

Read: rise and fall clauses in Australian construction contracts →
3

Your notice obligations may be running out right now

Notice time bars in Australian construction contracts typically run from 2 Business Days to 14 Business Days from the triggering event. A missed notice extinguishes an otherwise valid claim permanently.

Read: notice obligations for cost claims →
4

Fuel and input costs are running through your cost-to-complete

The 2026 Iran conflict pushed diesel, transport, plant and materials costs sharply higher. If your projects are fuel-sensitive, the gap between your tendered costs and actual cost-to-complete has widened significantly.

Read: fuel costs and construction in 2026 →
5

Shrinking margins are flowing into your cash flow

When costs cannot be recovered through the contract, the shortfall comes off margin. Reduced margin reduces the cash buffer that keeps your projects and your business viable.

Read: how rising costs compress construction margins →
6

Business survival risk may not yet be showing in your accounts

Construction failures in Australia are running at elevated levels. The warning signs frequently do not appear in management accounts until the position is already serious.

Frequently Asked Questions: Construction Cost Crisis Australia

Most calculate adjustment against a price index that moves more slowly than actual market costs. Caps, base date limitations and calculation methods frequently reduce what you recover to well below what you have actually spent. The clause needs to be read carefully before you rely on it. Rise and fall clauses in Australian construction contracts covers how these provisions work in practice.
Fixed-price does not mean no options. Your contract may contain variation entitlements, escalation provisions or force majeure clauses. Commercial avenues include negotiated variation and documented change requests. Fixed-price contracts and cost increases explains these, and a Standalone Contract Audit gives you written advice on your specific contracts.
Notice time bars in Australian construction contracts typically run from 2 Business Days to 14 Business Days from the triggering event. They vary by contract type. Missing or defectively giving a notice extinguishes an otherwise valid claim regardless of its merits. Notice obligations for cost claims sets out what is required under the main Australian contract standards.
Rachelle Hare, a Construction and Contracts Lawyer of 25 years, reviews your specific contracts, identifies what cost recovery mechanisms apply, assesses notice compliance and gives you written advice on your contractual position and commercial options.
