Accurate Cost Plans

Why Accurate Cost Plans are Essential in Value Engineering

9th July 2025   |   Liz Clarke   |   Reading Time: 4 minutes

Whatever the construction project, a robust cost management approach is key to its success. And with the added pressures of tight budgets, limited timelines, and heightened health and safety demands, the need to unlock value and manage risk becomes even more critical.

In these situations, clients need reassurance that quality won’t be compromised, and that’s where Value Engineering (VE) comes in. But it’s only as good as the cost data behind it. Using generic or outdated rates might seem like a quicker and easier option, but it’s not delivering the best value for the client.

At Evolution5, we believe in doing the job properly, not just taking the quick and easy route. Our cost management consultants are committed to raising the bar in Value Engineering by focusing on accurate, current and context-specific cost plans that deliver better value without comprising quality.

Raising the Bar in Value Engineering

In the construction industry, it’s still common practice to see cost plans built on standardised pricing data from resources like SPONS or BCIS. While these tools can be useful as a starting point, they’re no substitute for live, project-specific insight.

Early-stage input makes the biggest impact, which is why the feasibility stage is so critical. It’s the point where key decisions shape cost, quality, and long-term value. Getting expert advice at this stage helps avoid changes later and ensures the project is grounded in real value from day one.

Value Engineering isn’t just a cost-cutting exercise; it’s about delivering genuine value, and that takes diligence. It means making informed decisions using current market data, communicating with suppliers, and relying on real-world insights.

Due Diligence: More Than a Formality

Due diligence is the cornerstone of professional consultancy in Value Engineering. It’s not about taking shortcuts; it’s about doing the job properly. That means investing time and effort upfront to ensure that decisions are based upon the best possible understanding of value, risk, and potential.

Real VE requires real thoroughness. It’s about using up-to-date market intelligence, speaking to supply chain contacts, and stress-testing options based on actual project conditions—not theoretical averages.

Why Due Diligence Matters in Value Engineering

  1. Accurate Valuation and Negotiation

Good data supports good decisions. Accurate, transparent cost plans lead to fairer pricing and more constructive collaboration.

  1. Risk Mitigation

Early detection of financial or technical risks allows for proactive solutions, saving both time and money.

  1. Value Optimisation

By analysing each element of the design, due diligence helps identify smarter, more efficient alternatives that preserve or enhance performance.

  1. Informed Decision-Making

Clients rely on consultants to guide investment. Incomplete or outdated information leads to flawed decisions.

  1. Alignment with Objectives

Cost plans that reflect real market conditions help align budgets with the project’s vision avoiding compromise down the line.

Case Study: Delivering Value at King Alfred’s Campus, University of Winchester

A standout example of effective value engineering and cost management in action is our work at King Alfred’s Campus at the University of Winchester.

The project involved creating a vibrant, double-height atrium within a historic 19th-century building transforming the space into a flexible teaching area, with meeting rooms and new toilet facilities. Adding complexity, the adjacent learning and office spaces needed to stay fully operational throughout the build.

Evolution5’s cost management team worked closely with the architects and client team to meet the project’s design aspirations within tight budget constraints. Through close collaboration, live market engagement, and diligent oversight, the team not only ensured cost and programme control but also helped deliver:

  • A carbon emissions rate exceeding Building Regulations Part L2A by 17%
  • Recognition as a shortlisted finalist for an RICS Award

Samantha Helm, Head of Projects and Estate Management, University of Winchester, said:
“We were impressed with the cost management services provided by Evolution5 on this project. Their team is reliable and effective, and communications were good at every stage. They worked hard to resolve any issues that arose and kept us regularly updated. We would recommend their services to other organisations requiring cost management consultancy.”

A Call to the Industry: Raise the Standard

As quantity surveyors and consultants, we have a professional duty to base our advice on more than assumptions or averages. Accurate, project-specific cost data is essential to delivering real value.

At Evolution5, this is the standard we hold ourselves to on every project. We believe our clients deserve nothing less.

Frequently Asked Questions

Why is accurate cost planning important in Value Engineering?

Accurate cost planning is important in Value Engineering because it relies on current, project-specific data to deliver genuine value and produces a more realistic cost plan. Using outdated or generic rates can lead to poor decisions and compromise outcomes.

What’s wrong with using SPONS or BCIS alone in cost plans?

While useful as a baseline, SPONS and BCIS don’t reflect live market conditions. They cannot capture project specific factors that can influence the cost or programming of an item, such as region location, environmental conditions, accessibility and availability. Real value comes from engaging the supply chain and using up-to-date, context-specific data.

When should cost consultants get involved in a project?

Cost consultants should be involved in a project as early as possible, ideally from the feasibility and planning stages. Early involvement helps to set realistic budgets, identify potential risks, and shape effective procurement strategies, laying the foundation for successful delivery.

Why is due diligence important in Value Engineering?

Due diligence is essential in Value Engineering because it helps identify and mitigate risks early, saving time and money. It also supports accurate valuations and informed decisions, allowing teams to refine costs without compromising on quality.

How did accurate cost planning contribute to the success of the University of Winchester project?

By working closely with the design team, using accurate cost planning, and helping the team exceed carbon standards, Evolution5 delivered the project on budget and earned a place on the RICS award shortlist.
