Design & Verification
We complete the design — or we verify yours. Engineering assessments, life extensions, and independent verification for cranes and lifting equipment.
Independent engineering when the stakes are high.
Not every job is a major inspection. Sometimes you need an engineer to design a solution from scratch. Sometimes you need independent verification that someone else's design meets Australian Standards. Sometimes a crane built to overseas standards needs formal compliance validation before it can work in Australia.
That's what this page is about — engineering work that requires independence, rigour, and someone who'll put their name on a report that regulators and insurers will read.
Within Complete Crane Compliance, this is the engineering in between: the work that happens when an annual inspection finds something structural, when a crane approaches the major inspection trigger, or when equipment changes and someone has to sign off on it.
Life Extensions
Keep your crane working — with engineering evidence to back it up.
When a crane reaches the end of its original design life, it doesn't necessarily need to be retired. IDC conducts formal engineering assessments to determine whether continued operation is safe and compliant — and if so, under what conditions.
A life extension assessment considers the crane's actual duty history, structural condition, maintenance records, and operational environment. If the crane qualifies, we provide a formal written assessment that supports continued service for a defined period.
Lift Plan Verification
Independent engineering verification before a critical lift.
For complex or high-risk lifts, you need an independent engineer to verify the lift plan, check the calculations, and confirm the methodology is sound. IDC provides formal lift plan verification — an independent check by engineers with no stake in the job going ahead.
Engineering design and modification assessment
Original design, modification assessment and independent verification.
IDC develops engineering designs for crane modifications and assesses proposed or completed changes against the applicable Australian Standards and the crane's original design basis. We also independently verify designs prepared by others.
This includes boom modifications, counterweight changes, structural repairs, and any alteration that affects the crane's rated capacity or structural integrity.
Australian compliance for overseas equipment
Making sure overseas equipment meets Australian Standards.
A significant part of IDC's work involves verifying that cranes and lifting equipment designed or manufactured to overseas standards comply with Australian requirements. If you're importing equipment, commissioning a crane built to European or US standards, or inheriting a machine with non-Australian documentation, we assess its documentation and design against the applicable Australian requirements.
IDC assesses the equipment against the applicable Australian Standards — AS 1418, AS 2550, AS 4100 — identifies any gaps, and provides the engineering documentation needed to demonstrate compliance to regulators and insurers.
Compliance status assessments
When you need independent confirmation that a crane is compliant.
Regulators, insurers, and principal contractors sometimes require independent verification that a crane meets its compliance obligations. IDC provides formal engineering assessments and written reports that confirm (or identify gaps in) a crane's compliance status.
Our reports are referenced to AS 1418, AS 2550, and AS 4100, and are written to be read by people who know what they're looking for.
Why independence matters here.
Design and verification work only has value if the engineer doing it has no conflict of interest. IDC doesn't sell cranes, maintain cranes, or run a workshop. When we verify a modification, review a lift plan, or extend a crane's life, the assessment is based purely on engineering evidence and the applicable standards.
Our reports set out the assessment, evidence and applicable standards for review by your client, insurer or regulator.
