Occupied High-Rise Fire Remediation, Swansea Marina

A 13-storey residential high-rise at Swansea Marina required full fire remediation whilst remaining occupied throughout, a complex undertaking on a former brownfield site with a concrete frame and SFS infill construction.

We were appointed as principal contractor under a JCT ICD 2016 Part Design contract. Our involvement started early, with direct input into buildability, sequencing, and the fire remediation strategy for an occupied high-rise building.

When we stripped the original façade, it became clear the building was not vertically true. The original render system design was not feasible, and the appointed render manufacturer then went into administration. We reported the issue to the client immediately, engaged three alternative manufacturers, and when none could provide a warranty suitable for the coastal environment, developed a revised design to fully clad the building. We worked with the design team throughout, presenting value-engineered options and coordinating every stage of the change to protect the programme.

During the works, plastic MEV ductwork was found passing through the SFS wall system, a fire compliance issue with no proprietary solution on the market. We designed a bespoke metal duct sleeve, had it reviewed and approved by the project Fire Engineer, and delivered a compliant, repeatable firestopping detail. No strip-out required. No programme impact.

Working in a fully occupied building, resident communication was essential. We ran a structured liaison process: pre-notice letters, a single point of contact, regular coffee mornings, and a clear appointments system. We combined window replacement and putty pad installation into a single visit across 50 apartments, cutting disruption and reducing waste. Two complaints were received across that entire phase.

Before works started on site, we engaged Mid & West Wales Fire and Rescue Service directly. We extended the dry riser, provided secure access codes, and invited fire crews on site for training exercises and scaffold tours. The Fire Service carried out compliance audits throughout the works. We passed them all.

Materials removed during strip-out were repurposed on site. Pallets were rebuilt into the cutting station, old cladding boards used to construct a materials shelter, and balcony chippings laid as compound walkways. Surplus materials were donated to a local prison to support a Remembrance Day art installation, with further donations made to the local food bank. A mental health awareness banner was displayed on the scaffolding throughout.

One apprentice electrician was supported throughout. One Tenant Liaison Officer completed a work experience placement and has since moved into full-time employment on another project.
