Who we help

Best fit clients

Tier 2 and Tier 3 construction companies bidding for major Defence infrastructure work
Prime contractors responding to Defence open tenders and invitations to register interest
Businesses that want to improve compliance, clarity, and score potential across tender schedules

Sometimes a fit

Subcontractors bidding for Managing Contractor Works subcontract packages, where you need a standalone response that Managing Contractors can score independently

Not a fit

Providers without the capability or systems to meet mandatory requirements
Bidders relying on generic tender copy that does not address Defence documentation and evaluation expectations

Defence contract environments we support

We work within the contract environment and obligations set out in Defence construction documentation, including

Managing Contractor contract
Head Contractor contract
Medium Works contract
Estate Works contracts

We use this understanding to ensure your response aligns with the contract model and addresses what Defence expects from a construction contractor.

How Defence scores construction tenders

Defence and its advisors typically reward clarity, compliance, and delivery control.

To score well, you need to

Address every schedule in the structure requested, with no gaps
Show you understand the contract environment and delivery obligations
Present a program narrative that is practical, sequenced, and resourced
Link key personnel to delivery outcomes, governance, and decision-making
Evidence WHS, quality, and environmental systems as operating processes
Show risk controls and reporting as real routines, supported by evidence

Because our staff have acted as Defence construction purchasers and tender assessors, we focus on the evidence the Capital Facilities and Infrastructure Branch and the Security and Estate Group use to judge delivery confidence.

We check that you have

Matched attachments and evidence to the correct schedule questions
Aligned key personnel availability with the delivery period
Explained program logic and sequencing clearly
Shown how you manage WHS, quality, environment, and risk in practice
