Commercial Control Lost
Mid-Project Is Recoverable.
Mixed-use schemes are commercially complex by nature. Consequently, when cost control breaks down, the symptoms appear quickly – but the causes were established much earlier in the project.
What are your needs?
Variations Accumulating Fast
Variations are arriving faster than they can be assessed. Furthermore, the cumulative commercial impact has not been properly quantified and the contractor's position is hardening with every instruction issued.
Positions No Longer Match
The contractor's account and the client's cost plan no longer reflect the same project. Additionally, neither side can clearly account for the gap and the difference is growing with each valuation submitted.
Change Without Pricing
Change requests are being instructed without adequate pricing information attached. Moreover, programme pressure is being used to justify costs that have not been properly substantiated or independently verified.
Dispute on the Horizon
The project is approaching a point where formal dispute resolution is becoming increasingly likely. Therefore, you need an independent commercial position established now, before the final account process begins.
Stabilising the Commercial Position
Without Stopping the Project
On mixed-use developments, commercial breakdown rarely happens suddenly. It accumulates – in variations that were not assessed promptly, in scope gaps at the interface between uses, in changes instructed under programme pressure without proper pricing. Consequently, by the time the problem is visible, it is already embedded in the project records.
In practice, Reltic can be engaged mid-stream without requiring the client to stop and restart the commercial process. Subsequently, we establish the best available quantity baseline from current information, quantify the variation exposure and reinstate construction cost control on a defensible basis going forward. Furthermore, where design coordination has broken down between uses or consultant packages, we identify the scope gaps and establish what they cost.
Our Role
Independent quantity audit and commercial position established from current project records. Applied mid-stream without disrupting ongoing delivery of the works.
Our Method
Variation log reviewed, quantities reconciled, cost exposure quantified. A defensible commercial position established before the final accounts and disputes process begins.

The Mixed-Use Schemes Where We Add Most Value.
High-End ResidentialHigh-End Residential Projects
High‑value residential schemes need tight coordination between design intent, programme and commercial control.
Digital construction analysis gives early visibility of quantity assumptions, procurement exposure and delivery risks before construction begins.
Typical commercial pressures
- Complex coordination between multiple trades
- Programme constraints on tight, complex sites
- Cost plans based on incomplete design information
- Contractor pricing volatility
Complex Phasing Projects
Phased construction programmes need disciplined coordination between sequencing, access, logistics and commercial risk.
Digital construction analysis exposes assumptions, procurement exposure and delivery risks across phases before work starts.
Typical commercial pressures
- Programme instability across phased construction
- Site logistics constraints and delivery sequencing
- Coordination between contractors and trades
- Late-stage variation exposure across phases
Mixed-Use Developments
Mixed‑use developments demand precise coordination between different asset classes, programme logic and commercial control.
Digital construction analysis highlights cost, procurement and delivery risks across uses before construction begins.
Typical commercial pressures
- Coordination between retail, residential and other uses
- Programme sequencing where uses open at different times
- Procurement exposure across many specialist packages
- Cost planning complexity as value and spec vary by use
When quantities are established independently, traced to the model and documented from the start, the final account is not a negotiation. It is a reconciliation.
That is the difference between a cost plan that holds and one that does not.
By the Time the Problem Is Visible
It Is Already Expensive.
On mixed-use developments, the cost of commercial breakdown is not just the variation exposure itself. It is the cost of reconstructing a quantity baseline from incomplete records, of negotiating without evidence and of reaching a final account where the contractor’s position is stronger than yours. Consequently, the earlier an independent commercial position is established, the less expensive the recovery.
Furthermore, the projects where we add most value are not necessarily the ones that started badly. They are the ones where good projects lost commercial control at a specific point and need an independent construction cost consultant to re-establish it. That is a recoverable position. We do it without drama and without stopping the works.
Commercial Recovery.
Without Stopping the Project.
› Independent quantity baseline established from current records
› Variation exposure quantified and formally positioned
› Cost control reinstated on a defensible basis going forward
Independent Commercial Control.
Reinstated When It Matters Most.
If your mixed-use project has lost commercial control, the position is recoverable. As an independent quantity surveyor working exclusively on the client side, we establish a defensible baseline from whatever records currently exist. See how this applies on projects with late design changes and variation claim exposure.
