Estimating

What is value engineering in construction?

Value engineering (VE) is a structured review of a design to find ways to deliver the same required function, performance, and quality at a lower cost, usually by changing materials, systems, or methods.

Value engineering asks one question of every major system: is there a cheaper way to do what this needs to do, without giving up anything the owner actually needs? The key word is function. Swapping a spec'd curtain wall for a cheaper one that leaks is not VE. Changing a steel frame to a different bay layout that uses less tonnage, with the same loads and spans, is.

VE happens at two points. During design, the owner may hold VE sessions with the architect, engineers, and contractor to bring an over-budget design back in line. After award, the contractor may submit a value engineering change proposal (VECP) offering a cheaper alternative and sharing the savings.

How federal VE sharing works

Federal construction contracts include the clause at FAR 52.248-3, Value Engineering, Construction. It defines a VECP as a proposal that requires a change to the contract and lowers the price or estimated cost without impairing essential functions or characteristics. The clause sets out how savings are split: the government's share of net instant contract savings is 45 percent on fixed-price contracts and 75 percent on cost-reimbursement contracts, which leaves the contractor the remainder. It also gives the contractor 20 percent of projected collateral savings (for example, lower operating costs) for a typical year of use, subject to a cap. The contracting officer decides whether to accept, and until a VECP is accepted, the contractor keeps performing the original contract.

Private contracts have no standard rule. Some split savings, some give it all to the owner, and many say nothing, which is worth negotiating before you put engineering time into a proposal.

A worked example

Say a GC on a $7 million private office building is $400,000 over the owner's budget at design development. In a VE session, the team looks at the big systems. The mechanical sub proposes a different rooftop unit arrangement that cuts ductwork and saves $85,000. The structural engineer agrees to change the slab from 6 to 5 inches over a portion of the floor where loads allow, saving $40,000. The owner rejects a proposal to downgrade the exterior cladding because it changes the building's look, which is a function the owner cares about.

VE log (example)
ItemSavingsDecision
Rooftop unit and duct reconfiguration$85,000Accepted
Slab thickness change in low-load areas$40,000Accepted after engineer review
Cladding downgrade$110,000Rejected, affects appearance
Lighting fixture substitution$32,000Accepted with equal-performance check

Accepted VE items total $157,000. Each one is written up, priced, approved, and incorporated into the drawings or a change order.

When VE goes wrong

  1. Cost cutting called VE. Cheaper materials that shorten life or raise maintenance are not value engineering. Look at total cost of ownership, not just first cost.
  2. Design liability left vague. If the contractor proposes a design change, agree who is responsible for engineering it.
  3. Lost in documentation. Accepted items never make it into revised drawings, so the field builds the original design.
  4. Late VE. Changes after procurement often cost more in redesign and restocking than they save.

Related terms

VE works best with early contractor input through preconstruction and a constructability review. Compare it with a substitution request, which proposes a different product but not necessarily a lower cost.

Frequently asked questions

Is value engineering just cost cutting?

It should not be. True VE keeps the required function and quality and finds a cheaper way to deliver it. Cutting scope or quality is a different decision and should be called that.

Who benefits from value engineering savings?

It depends on the contract. Federal contracts use the sharing rules in FAR 52.248-3. Private contracts may share savings, give them all to the owner, or be silent.

What is a VECP?

A value engineering change proposal: a contractor's formal proposal, after award, to change the contract in a way that lowers cost without hurting essential functions.

When is the best time for value engineering?

Early in design, before drawings are complete and before materials are bought. The later VE happens, the more redesign and rework eat into the savings.
