HAKI TEMPORARY ROOF PART OF ALLTASK’S INNOVATIVE ACCESS SOLUTIONS FOR A LANDMARK SUSTAINABLE DEVELOPMENT

UCB’s Windlesham Campus is a landmark new R&D headquarters located in Surrey, with sustainability at its core. The campus blends retained existing structures with newly constructed, purpose-built facilities, all designed to foster collaboration across the site. At its centre is a three-storey timber collaboration hub which connects various wings of the facility and promotes interaction. To accommodate this new addition, the 1967 Biology East Wing and adjoining courtyard were demolished.

This development stands as one of the most technically complex and high-profile projects Alltask has been involved in.

The distinctive architecture and intricate timber construction demanded innovative access strategies. As the scaffolding and access contractor, Alltask played a key role in supporting the safe and efficient delivery of works across multiple disciplines and construction phases.

Alltask was responsible for the in-house design, supply and erection of all access-related systems, including:

- External and internal scaffolding

- Temporary roofing installations

- Bespoke access structures

- Support for timber structure installation

- First and second fix M&E works

- Roofing and façade packages

- General construction logistics

- Asbestos removal services

One of the key aspects of the project was a Haki Temporary Roof and Specialist Access for the Collaboration Hub and Main Structure.

The collaboration hub is a distinctive, petal-shaped timber structure that required tailored access solutions. Its unique curved geometry demanded carefully engineered scaffolding platforms, independently tied systems and customised configurations to follow the non-linear roofline. Internally, Alltask installed crash decks, mobile towers and high-level platforms to support ceiling works and service installations - all fully compliant with TG20:21 and SG4:22 guidance.

To protect the main structure from weather exposure Alltask erected a large span temporary Haki roof measuring 78 metres in length and 34.5 metres in width. Fully enclosed in Monarflex sheeting and equipped with an integrated water management system, the roof enabled a full strip and re-roof of the existing building prior to new plant installations.
