Behind one demolition is a new civil engineering lab built to test how roads fail

A new civil engineering lab at the University of Portsmouth is moving from plan to site work, with demolition under way and the replacement building aiming for an Outstanding BREEAM UK rating.

Before the new building rises, the old one has to come down.

At the University of Portsmouth, demolition of the Wiltshire South Wing has begun as the first visible step towards a new civil engineering lab. It is the sort of early works stage that can look purely procedural from outside. In practice, it is the moment a project stops being a rendering and starts becoming a place where future engineers will learn how structures, materials and ground behaviour perform in the real world.

In brief:

• Demolition of the Wiltshire South Wing has begun at the University of Portsmouth.
• The work is preparation for a new civil engineering lab.
• The planned building is aiming for an Outstanding BREEAM UK rating.

Civil engineering lab work starts with the part most people never notice

There is a plain truth about technical buildings: the glamorous bit is never the start. Laboratories do not begin with ribbon-cutting. They begin with clearance, sequencing and hard decisions about what an old building can no longer do. For a university, that matters beyond the campus boundary. Civil engineering teaching is tied to the same questions the highways sector wrestles with every day: how materials behave under load, how structures age, what water does when it finds a weak point, and how to design assets that last longer and waste less.

The University of Portsmouth has said the demolition is the preparation stage for its new civil engineering lab. It has also said the building has been designed with a range of sustainable features and is aiming for an Outstanding BREEAM UK rating, one of the highest available under the UK assessment method. That matters because specialist teaching buildings are energy-hungry by nature. They need space, services and equipment. Hitting the top tier means the environmental performance has been designed in, rather than left as a nice idea for later.

For highways readers, the interesting part is what a civil engineering lab is actually for. This is where theory gets forced to behave like reality. Students and researchers can test materials, study structural behaviour and work through the kind of practical engineering problems that sit underneath roadbuilding and maintenance, even if drivers never see them. Loads, cracking, drainage, durability and failure modes all sound abstract until they become a collapsed retaining wall, a weakened bridge deck or a carriageway that has started to move.

That gap between classroom and site is where facilities like this earn their keep. Good transport infrastructure depends on people who understand not just design codes, but why assets deteriorate in service and how to inspect, maintain and replace them sensibly. The industry is short of those people in enough places already. Recent recruitment pushes across major infrastructure have made that point rather loudly, whether on contractor graduate schemes or the transport control roles drivers almost never think about. Training space is not a side issue. It is part of the supply chain.

Demolition itself is also a reminder that construction projects often start with subtraction. Before the first foundation is poured, teams need to remove existing structures safely, manage waste streams and prepare the site for what comes next. On constrained sites, especially in university estates, that can mean carefully staged work to reduce disruption while keeping adjacent buildings functioning. It is not glamorous, but it is engineering discipline in miniature: sequence first, build second.

The sustainability angle deserves more than a passing nod too. BREEAM, the Building Research Establishment Environmental Assessment Method, is the UK’s best-known building sustainability rating system. An Outstanding target signals a scheme aiming at the highest level of environmental performance. In practical terms, that usually means the design team is thinking hard about energy use, materials, water, waste and how the building performs over its whole life, not just on opening day. That line of thinking is increasingly familiar in highways as well, where lower-carbon materials, life extension and whole-life value are steadily overtaking the old habit of judging everything by the first invoice.

The Portsmouth project is not a road scheme, and it does not pretend to be one. But it does sit close to a question the sector keeps returning to: where the next generation of engineers will come from, and what sort of spaces they need if they are going to work on more demanding infrastructure than the last cohort inherited. Roads, bridges and drainage systems are not becoming simpler. Neither is the pressure to cut carbon while keeping networks open.

So the image here is less dramatic than a new bridge launch or a weekend motorway closure. It is a demolition job on a university site. Yet that first act is doing something larger. It is making room for a building designed to teach civil engineering as a practical craft, backed by a sustainability standard that is difficult to reach and harder still to reach by accident.

For students, it should mean better facilities and more direct contact with the mechanics of how infrastructure behaves. For the wider sector, it is a small but real signal that the pipeline into engineering still depends on physical places, specialist kit and long-term institutional commitment. You do not train people to understand failure, loading and durability purely from slides on a screen. Sometimes the story really does start with knocking a wall down.
