# Optimising Early-Stage Project Value

> Early involvement of engineers and use of digital tools like BIM are not buzzwords. They are proven methods of preventing costly redesigns, delays, and operational headaches.

The decisions that decide what a building costs to build and to run are taken before anybody has drawn it in detail. That is the window this piece is about.

## Why early engineering involvement matters

Value engineering at the early design stages has the greatest impact on total project cost and performance: not just construction cost, but the maintenance and operational expense over the building's lifecycle. Studies show savings of up to 10% in construction phase time and 7% in cost through early contractor and engineer involvement, especially on complex projects.

## Digital workflows and BIM

- [BIM](https://www.petruf.ie/services/building-information-modelling) adoption provides quantifiable gains: elimination of up to 40% of unbudgeted change, cost estimates accurate within 3%, and project time improvements of up to 7%, according to Stanford CIFE's analysis of 32 major projects.
- Collaborative BIM allows all stakeholders to visualise, analyse and coordinate project systems in real time, reducing design errors and accelerating decisions.

## Case studies

- Savannah State University: [BIM driven](https://www.petruf.ie/blog/bim-implementation-in-precast-concrete) option analysis resulted in a $1.99 million upfront cost saving at pre-design. Directors could walk through the scenarios virtually, which made the decision defensible as well as confident.
- Early engineering involvement prevents the design clashes that, left unresolved, drive up change orders and claims during construction.

## How directors make it happen

- Select collaborative, integrated delivery systems, such as integrated project delivery or [early contractor involvement](https://www.petruf.ie/blog/early-contractor-involvement-in-precast) agreements, to unite all disciplines from project inception.
- Invest in BIM training for teams and mandate digital coordination in contracts, so live updates and clash detection are used throughout design and construction.

## Risk mitigation and business strategy

- Directors who audit regulatory risks, water and flood among them, and technical risks with engineering input from day one avoid the approval delays and scope changes that are leading sources of cost and time overrun.
- Continuous digital monitoring and integrated decision platforms allow for fast course correction and transparent reporting, which is what market and stakeholder confidence is built on.

## Why business as usual is ruinous

Traditional design, bid, build sequencing is the main culprit behind most budget overruns, schedule delays and rework waste. It systematically ignores the value engineers add at the start. Directors have to challenge that inertia or watch competitors deliver faster, cheaper and with fewer claims.

Directors who engage engineers and adopt digital tools from the outset build projects that are faster to market, cheaper to run and easier to manage. The industry data and the case studies make that not just plausible but proven.

## What people ask after reading this

### When are the decisions that set a project's cost actually made?

Before anybody has drawn it in detail. Value engineering at early design has the greatest impact on total cost and performance, and that includes what the building costs to run rather than only what it costs to build.

### What does BIM return at that stage?

The figures in this piece: up to 40% of unbudgeted change eliminated, and cost estimates accurate to within 3%.

### What delivery model supports early involvement?

An integrated one. Integrated project delivery or early contractor involvement rather than design, bid, build, which is the sequencing behind most budget overruns and rework.
