Powerproject underpins Willmott Dixon’s move to modern off-site manufacturing techniques

Powerproject®

Willmott Dixon is pioneering off-site manufacturing techniques nationally after winning awards for its prefabricated construction of the University of Warwick’s Interdisciplinary Biomedical Research Building.

Global sustainability concerns are driving construction companies to look for alternative, technology-driven ways to assemble buildings.

By manufacturing 50% of the building off-site and coordinating operations using Powerproject by Elecosoft, Willmott Dixon Construction Manager, Nick Preedy, reduced site deliveries by nearly 40%, lowering the building’s carbon footprint.

The project has unlocked a whole new revenue stream for the company, which is now growing its off-site manufactured projects to promote greater sustainability in construction.

The Net Zero World initiative is driving construction companies to look for alternative, technology-driven ways to construct off-site manufactured buildings. Willmott Dixon is paving the way for environmentally-friendlier processes which is evidenced in the successful erection of the University of Warwick’s 7,000 square metre, five-storey Interdisciplinary Biomedical Research Building (IBRB) in 2020.

Delivering first-class facilities through innovative techniques

Nick Preedy has delivered two multi-million pound projects for the University of Warwick in his role as Construction Manager at Willmott Dixon.

The first – a 1,550 square metre Sports and Wellness Hub – received gold honours in the Leisure category at the 2019 UK Construction Manager of the Year (CMYA) Awards. And its successful execution led to Willmott Dixon being commissioned to manage construction of a £33 million Interdisciplinary Biomedical Research Building at the university’s Gibbet Hill campus in 2020.

With a three-month overlap between completing the Sports and Wellness Hub and breaking ground on the IBRB project, careful planning was critical to maintain high standards of work. Nick and his team used Powerproject for both – however, the software played a pivotal role in determining how the research centre would be constructed.

Ambitiously, Willmott Dixon proposed a modern methodology for the IBRB, prefabricating 50% of the building off-site. This pre-manufactured value (PMV) would include a hybrid pre-cast concrete frame, glulam timber frame, and 2,000 square metres of pre-glazed concrete cladding.

Creating a business case for sustainable construction

While the use of off-site manufacturing techniques is growing fast in the construction industry, when Willmott Dixon first pitched the idea to the University of Warwick, it was a very new approach.

To prove the benefits of pre-fabrication, Nick’s team used Powerproject to demonstrate that off-site manufacturing would reduce the number of site deliveries from 4,000 to 2,200 and halve the number of workers.

Just eight installers and two supervisors were needed to assemble the precast concrete frame, while three people could put the timber frame together, and the cladding could be installed by four people using one tower crane.

Streamlining on-site resources significantly reduced disruption to the 26,000 students and 7,000+ members of staff that work on the University of Warwick campus. And the proposal also included designing a 27-metre tall factory-assembled mega-riser, which could be installed in just two days – saving 18 weeks on the project timeline.

“We used Powerproject to plan timelines for a traditional build versus using modern off-site construction methods. We were able to show the university that not only were they getting a higher quality build, but our approach resulted in half as much disruption to students and staff.”

In addition to saving time and complexity, Willmott Dixon’s use of modern methodologies also reduced the project’s climate footprint. Pre-fabrication limited material waste, and fewer deliveries generated lower vehicle emissions. This was enhanced by the decision to clad the building with 390 vertical PV solar panels to offset 4,600kg of CO2 emissions, in-line with the university’s strategy to become net zero by 2030.

Using construction planning software to stay on schedule

Although off-site manufacturing is more efficient, there are risks to this approach, as every element has to be delivered on-time and built to specification.

Using Powerproject, Willmott Dixon was able to create risk profiles that identified critical points where time could be lost, modelling the consequences of delays and how work could be rescheduled.

“Without having Powerprojet in place, I don’t think we would’ve committed to some of the off-site components that made the project such a huge success. We could see exactly what everyone needed to do and model the impact of any changes on the project as a whole.”

Flexibly planning capabilities paid dividends during the pandemic, as Nick reacted quickly to delayed glazing deliveries – installing temporary weather protection and rerouting perimeter services affected by scaffolding being in place longer than expected.

But ironically, despite being able to adjust schedules easily using construction project management software, the team’s decision to use modern assembly methods meant Covid-19 had little impact on progress. In fact, Willmott Dixon was able to deliver the Interdisciplinary Biomedical Research Building on-schedule in just 118 weeks.

Keeping a close eye on off-site manufacturing progress

In addition to supporting on-site activities, Powerproject played a pivotal role in helping Willmott Dixon to coordinate off-site manufacturing requirements.

The off-site construction supply chain is still immature, so Nick and his team expanded their remit to lead manufacturing logistics – using Powerproject to gather true time and resource data from stakeholders.

“We spent more time visiting factories than actually being on-site during the project. During those visits, having Powerproject open in meetings allowed us to capture data from our contractors and input it there and then, so the timeline was always completely up-to-date.”

By taking ownership of the full project management scope, Willmott Dixon was able to capture every piece of data that was within Powerproject without needing to integrate third-party software, for a complete overview of project progress.

Several manufacturers were so impressed by Powerproject that they decided to invest in the software themselves; meaning Willmott Dixon has a common technology in place for future construction projects.

The University of Warwick was also impressed by the insights Powerproject delivered. Instead of creating PDF reports, Nick’s team held a weekly call with university staff on a Friday afternoon, screen sharing live data from Powerproject. The university has since instigated weekly catch-ups for all its campus development activities.

University of Warwick IBRB construction: results recap

By using Powerproject construction planning software to prove and drive modern methodologies, Willmott Dixon was able to:

  • Reduce on-site deliveries by 40% to cut the project’s carbon footprint
  • Halve the number of on-site staff for a cost-efficient, socially distanced operation
  • Deliver a 7,000 square metre five storey building on-schedule in just 118 weeks
  • Easily manage the impact of setbacks including a delayed glazing delivery
  • Expand its project management remit to coordinate the off-site construction supply chain
  • Dynamically communicate project progress to build a transparent, trusted working relationship with the contractors and the university
  • Create the University of Warwick’s most sustainable space on campus

And the icing on the cake: Nick Preedy won gold in the Higher Education category at the 2021 UK Construction Manager of the Year (CMYA) Awards.

Powerproject: a catalyst for change

Beyond being a modern, efficient way of managing the University of Warwick’s requirements, the IBRB project opened Willmott Dixon’s eyes to the wider potential of prefabricated assembly models.

Having proved he could deliver an award-winning project using new methodologies, Nick was given a position within Collida, Willmott Dixon’s integrated construction platform for sustainable design, procurement, delivery and maintenance using cutting-edge technology.

Nick’s new role includes looks after Willmott Dixon’s national network of manufacturing partners, strengthening off-site production by introducing planning and execution best practices.

“Many of the manufacturing companies I see wouldn’t have had any construction planning software in place two or three years ago. Now, they’re sitting in front of me presenting plans on Powerproject. We’ve come full circle.”

Nick’s new remit has also changed his use of Powerproject. Instead of putting together 12-18 month project timelines, he now produces day-by-day assembly guides to standardise the implementation of prefabricated construction products – from residential housing through to commercial buildings, schools and healthcare centres.

As each building is based on a pre-designed template, Nick’s work enables customers to see the full vision for their project from day one. While clear instructions empower Willmott Dixon and partners to assemble buildings in a quick, cost-effective manner, with minimal waste.

“With the support of Powerproject, Willmott Dixon has modernised its design and procurement processes, on-site deliveries and assembly services, which is allowing us to explore new opportunities in key markets. We’re revolutionising the way we run projects and aligning our services with the virtual world in which we’re working.”
