protecting margin, program & delivery certanty
engaging before tender & construction, where risk is priced, and value is captured or lost
Calli Group provides design and construction advisory for builders at the point where projects are priced — and where margin is either protected or eroded — before tender and before construction begins.
We work across early design, tender and delivery to identify hidden risk and unrealised value embedded in documentation, consultant decisions and procurement assumptions.
In parallel with risk identification, we focus on unlocking value through smarter, construction-led design decisions, including:
Rationalising unnecessary design complexity that drives cost
Identifying more efficient structural solutions aligned with build methodology
Challenging over-design and under-performance across key building systems
Optimising material selection for cost, availability and constructability
Improving construction detailing to reduce labour intensity and sequencing inefficiency
Aligning design resolution with procurement strategy and trade packaging
These interventions are targeted early — while change is still inexpensive and value can be realised, not retrospectively “value engineered” under delivery pressure.
how we do it
Four targeted intervention points where construction risk is reduced and margin is protected.
Where margin risk is created, or avoided
We engage before or during tender, when documentation quality directly influences pricing accuracy, risk transfer and claims exposure.
Scope gaps and ambiguous consultant responsibilities
Coordination failures between architectural, structural and services design
Buildability, access and sequencing constraints
Design assumptions that drive pricing risk and latent claims
Misalignment between design intent and construction methodology
Clearer tenders, fewer RFIs and reduced margin erosion.
02. tender auditing
Identifying risk & value before it is priced or transfered
We undertake targeted pre-tender audits of documentation to identify design, contractual and delivery risk before tender submission.
We focus on areas where risk is commonly embedded or transferred, including:
Principal’s Project Requirements (PPRs)
Principal’s Design Requirements (PDRs)
Geotechnical and site condition information
Interface, staging and sequencing assumptions
Provisional allowances and latent risk exposure
We also assess alignment between design intent, documentation and procurement strategy to clarify risk before pricing.
Reduced tender ambiguity, clearer risk allocation, more reliable pricing and improved commercial certainty.
Removing ambiguity before it becomes a cost
We audit consultant and project documentation to resolve:
Scope and responsibility gaps
Coordination and interface risks
Staging and sequencing conflicts
Buildability constraints
Cleaner documentation, reduced variations, controlled claims exposure and risk identified early.
04. delevery phase assurance
Where risk is priced and value Protecting margin during construction
We support delivery teams during construction to manage emerging risk, maintain alignment between design intent and site reality, and prevent avoidable cost escalation.
Auditing emerging documentation conflicts and late design changes
Maintaining alignment between consultants, trades and construction methodology
Fewer surprises, controlled cost outcomes and reduced dispute tension.
