What HSP Advisory Provides

We provide practical, project-facing GC21 support that can be used by commercial

managers, contract administrators, project managers and directors throughout

delivery.

1. GC21 Contract Administration Support

 Set up practical contract administration processes for notices, instructions,

authorities and reporting

 Prepare and manage GC21-compliant notices, correspondence and claim

pathways

 Provide ongoing commercial and contract advisory support during project

delivery

2. Claims, EOT and Entitlement Management

 Prepare, review and defend Extension of Time (EOT), delay, disruption and

cost claims

 Develop entitlement preservation strategies before contractual time bars

become a problem

 Build evidence packs that connect contract clauses, facts, records,

programmes and quantum

We align claims with GC21 mechanisms to ensure compliance with timing,

evidence, and notice requirements, improving success outcomes.

3. Variations and Change Management

 Identification and assessment of variations

 Pricing, substantiation, and negotiation support

 Managing instruction pathways and scope changes

GC21 requires disciplined management of instructions and scope—our approach

ensures variations are captured, compliant, and commercially optimised.

4. Risk, Compliance and Dispute Avoidance

 Contract risk identification and mitigation strategies

 Compliance with statutory, WHS, and government obligations

 Early warning and issue escalation frameworks

GC21 is structured to encourage early identification and resolution of

issues—we ensure this principle translates into real project outcomes.

5. Subcontractor and Supply Chain Contract Management

 Flow-down obligation reviews (including payment and compliance obligations)

 Subcontract and procurement strategy advice

GC21 places responsibility on contractors to manage subcontractor compliance,

including key contractual and statutory obligations.
