Test the saving before accepting the trade-off.

We use model quantities and cost rules to compare options on a consistent basis. Teams can see what changes, what it saves and what else it affects.

Value engineering needs more than a lower total.

BIM cost optimization uses model-based quantities to compare design, material, system and construction-method options. Each scenario is measured against a common baseline so cost movement can be traced to specific geometry, specification or delivery changes.

A cheaper unit rate may increase material volume, interfaces or waste. A simplified design may reduce fabrication cost while shifting work into temporary works, programme or another trade package.

CNE structures the comparison around whole-option consequences visible from the available information. We quantify direct differences, state unresolved impacts and preserve engineering and coordination constraints rather than treating minimum initial cost as the only outcome.

Alternatives compared on one basis

01
Baseline definition

The current design, quantities, rates, scope boundaries and relevant constraints are frozen as the comparison reference.

02
Option modelling

Alternative geometry, materials or methods are represented at sufficient detail to measure meaningful differences.

03
Quantity and cost comparison

Added and removed scope is mapped to the same cost structure, units and pricing assumptions used for the baseline.

04
Waste and repetition review

Panel sizes, standard components, cut patterns and repeated assemblies are examined for measurable material efficiency.

05
Interface impact check

Structural, architectural, MEP and construction consequences are recorded where an option shifts work beyond its own package.

06
Decision package

CNE issues side-by-side quantities, costs, assumptions, risks and model views for review by design and commercial teams.

Savings tested against engineering reality

Every option uses one baseline

Consistent measurement and rate assumptions prevent apparent savings created by comparing unlike scopes.

Interfaces remain part of the decision

We identify when one package saves cost by transferring work, risk or complexity to another.

Consequences stay traceable

Quantity differences link back to model elements and stated assumptions, giving reviewers a defensible decision record.

Compare the options before changing the design.

Send us the baseline model, proposed alternatives and cost basis. CNE will quantify the differences and expose the wider delivery consequences.
