On many projects, "value engineering" means something very specific: the tender came in over budget, and now everyone is in a room crossing out finishes, deleting the canopy and swapping the specified equipment for something cheaper. That isn't value engineering. It's cost cutting under a better name, and it often costs more over the life of the building than it saves at tender.
Real value engineering is a structured method with a long track record. Done at the right time, it improves what the owner gets for the money. This guide explains what it is, how function analysis makes it different, when to do it, and how an owner should evaluate the proposals it produces.
What value engineering is
SAVE International, the main professional body for the discipline, describes value methodology as a structured process in which a cross-disciplinary team, led by a qualified facilitator, analyzes functions to improve value. It expresses value as a ratio: the performance of the functions the owner needs, divided by the resources (money and time) spent to get them.
That ratio is the point. Value can rise because cost falls, but it can also rise because performance improves for the same money. A proposal that cuts cost and also cuts a function the owner needs doesn't add value. It just moves the problem.
The U.S. Whole Building Design Guide, maintained by the National Institute of Building Sciences, is blunt about the distinction: value engineering is not a design peer review or a cost-cutting exercise. The U.S. Federal Highway Administration makes the same point in its guidance, describing VE as a way to add value and quality, not simply to reduce costs.
In Canada, Value Analysis Canada notes that value analysis, value engineering and value management describe the same method. The names differ by industry and era, not by substance.
Function analysis: the part that makes it different
What separates value engineering from a cost review is function analysis. Before anyone suggests alternatives, the team defines what each part of the project must do, stated as an active verb and a measurable noun. A storefront might "display merchandise" and "admit light." A loading dock canopy might "protect goods." A mechanical system might "condition air" and "control humidity."
Once functions are named, each one can be given a cost. That's often revealing. On programs we've supported, function analysis regularly shows a large share of cost tied up in secondary functions, such as appearance features nobody asked for or redundancy beyond the owner's actual requirements, while a basic function the owner cares about is underserved.
The Function Analysis System Technique (FAST) takes this further by mapping how functions relate. Asking "how?" moves toward the solution. Asking "why?" moves toward the owner's real objective. A canopy exists to protect goods, which exists to keep stock saleable. Once that chain is clear, the team can ask whether there's a better way to keep stock saleable, which is a much more useful question than how to make the canopy cheaper.
The job plan
Value engineering follows a fixed sequence called the job plan. SAVE International describes eight phases:
View the data
| Phase | What happens |
|---|---|
| 1. Preparation | Set scope, team and timing |
| 2. Information | Gather drawings, costs, constraints |
| 3. Function analysis | Name functions and their cost |
| 4. Creativity | Generate ideas; no judgment yet |
| 5. Evaluation | Screen ideas against criteria |
| 6. Development | Cost, LCC, risks for best ideas |
| 7. Presentation | Proposals to decision-makers |
| 8. Implementation | Accept, revise, build into design |
The creative phase depends on keeping judgment out of it. Ideas are listed first and evaluated later, so the obvious answer doesn't crowd out the better one. The development phase is where ideas become proposals, with costs, life-cycle effects, drawings and risks set out so a decision-maker can accept or reject each one.
A typical study is a workshop of several days. The Whole Building Design Guide describes a workshop of about 40 hours, less for smaller projects. FHWA suggests a team of about five to eight people from different backgrounds generally works well. The team should include people independent of the design, alongside the designers who know why decisions were made.
Timing: early beats late
Value engineering can be done at any stage, but the return falls the later it starts. The Whole Building Design Guide notes that earlier application generally gives a higher return, and that changes at the planning stage have very little effect on schedule or redesign cost. FHWA's advice is to hold a study as soon as there's enough information, with an optional second study during final design.
The reason is simple. At concept stage, changing the structural system, the building form or the site layout costs a few weeks of design time. After construction documents are complete, the same change means redesign, re-coordination, new permit drawings and possibly re-tendering. By then, the only changes that pay for themselves are usually the small ones.
That's why VE done after a high tender so often turns into cost cutting. The study is too late to change anything fundamental, so it changes what's easy instead: finishes, equipment quality and scope.
Value engineering versus cost cutting
- Starting point. VE starts from the functions the owner needs. Cost cutting starts from the line items that are biggest or easiest to change.
- Measure. VE judges proposals on life-cycle cost and performance. Cost cutting judges them on first cost.
- Timing. VE is planned into design. Cost cutting is a reaction to a tender result.
- Outcome. VE can make a building cheaper and better at once. Cost cutting usually makes it cheaper and worse, with the cost showing up later in operations, maintenance or tenant complaints.
Sometimes a project needs scope reduction. That's a legitimate decision, but it should be made openly as a scope decision, not presented as value engineering.
How to evaluate VE proposals
A VE study produces a list of proposals, each with a claimed saving. Not all of them should be accepted. In FHWA's survey of fiscal year 2017, state transportation agencies carried out 160 VE studies that produced 1,451 recommendations, of which 636 were approved, about 44%. The approved recommendations were valued at roughly $1.05 billion against about $6.6 million in study costs. The method pays off, but only because someone sorted the good proposals from the weak ones.
For each proposal, an owner should ask:
- Is every required function still delivered? Check against the owner's project requirements, not just the drawings.
- What's the life-cycle effect? A cheaper roof, mechanical unit or flooring can cost more over 20 years in energy, maintenance or early replacement. Our guide to life-cycle cost analysis explains how to compare them.
- What does it cost to implement? Redesign fees, coordination, permit revisions and schedule time all come off the headline saving.
- Who carries the risk? A substitution proposed by a contractor can shift design responsibility, warranty or performance risk. Treat it like a change order, with the design team's review.
- Is the saving real? Confirm it with the cost consultant, not just the proposer.
The Whole Building Design Guide recommends that contractor-proposed VE changes during construction be evaluated from life-cycle and liability perspectives, with the design team involved, and handled like change orders, including their effect on schedule and productivity. Our guide to managing change orders covers that process.

VE and the delivery model
How value engineering works in practice depends on how the project is being delivered.
Design-bid-build. The owner controls the design until tender, so the owner controls VE. This is the model where an early, independent study is easiest to run and has the most effect. After award, VE ideas usually come from the contractor as substitution requests, and the owner has to evaluate them one at a time.
Construction management and early contractor involvement. Bringing a contractor in during design gives the VE team real pricing and constructability knowledge, which is a major advantage. The risk is that "VE" becomes a running list of substitutions that favour the contractor's buying or methods. Keep function analysis and the owner's requirements at the centre.
Design-build. Once the design-builder is contracted, savings from design changes often belong to the design-builder unless the contract says otherwise. Owners who want VE to benefit them should hold a study on the reference design before procurement, and set out in the contract how later savings are shared. Get legal advice on that wording. Our guide to design-build for owners covers the contract model.
What owners should do
- Plan VE into the design schedule. Hold the main study at concept or schematic design, with an optional second study during design development.
- Insist on function analysis. A study that goes straight to a list of cheaper materials isn't VE.
- Use an independent facilitator, ideally a Certified Value Specialist, with designers in the room but not running it.
- Evaluate every proposal on life-cycle cost and implementation cost, not on headline first-cost saving.
- Call scope reductions what they are, and record them as owner decisions.
The bottom line
Value engineering is one of the best-value exercises an owner can run, and one of the most misused. Held early, with real function analysis and honest evaluation, it improves the building and its budget at the same time. Held late, as a reaction to a high tender, it usually becomes cost cutting with a nicer label. The difference is mostly timing, and timing is the owner's decision.
