Project Overview
The Spectra building at the University of Hertfordshire is a large-scale STEM facility designed by BDP and delivered by Morgan Sindall Construction. The façade combines traditional masonry at lower levels, mechanically fixed MechSlip brick slip cladding above, and metal rainscreen elements across upper elevations. This layered façade approach creates a strong architectural character but brings considerable technical and coordination challenges.
The Challenge
The project required control across complex geometry, including sawtooth brick-slip elevations with sharp angles and directional changes. These conditions increased visibility of any deviation and required tight tolerance control across large elevations. At the first floor level, the façade transitions from traditional masonry to the mechanically fixed MechSlip brick-slip system. This interface required careful coordination to maintain alignment of brick coursing and ensure visual continuity between the two construction methods.
The Solution
Aquarian Cladding Systems supplied the MechSlip mechanically fixed brick cladding system, manufactured by Ash & Lacy. The system enabled accurate setting out, reduced structural loads, and supported an efficient installation aligned with programme requirements. The mechanically fixed approach removed reliance on wet trades and provided a repeatable installation method across both flat and angled elevations. A visual mock-up (VMU) was constructed prior to commencement on site, providing a benchmark for quality, alignment, and detailing throughout the build.
Installation and Coordination
Craft Facades undertook the design and installation of the MechSlip brick slip system. Their role was key in translating the design into a consistent finished façade. The starter rail at the
first-floor level controlled the entire upper façade, demanding precise coordination with the traditional brickwork below. Across the sawtooth elevations, joint lines were maintained through
directional changes using fixed datums and controlled tolerance management. Installation followed the full façade system, coordinating brackets, rails, and adjacent trades to preserve
alignment.
Commercial Impact
The MechSlip system reduced programme risk by enabling faster installation compared with traditional masonry above the first-floor level. The mechanically fixed approach was less weather dependent, improving predictability and supporting programme certainty throughout construction. Structural efficiency was improved by reducing façade weight, consequently supporting the steel frame construction. Quality was maintained using consistent brick coursing, clean detailing, and accurate alignment across complex geometry.
The Result
The completed façade delivers a clean and consistent finish across a complex building envelope. Sawtooth elevations are executed with precision, and transitions between traditional
masonry and brick-slip cladding are seamless. The façade achieves the intended architectural outcome while keeping performance and buildability.
Conclusion
The Spectra building demonstrates how the MechSlip brick cladding system can deliver complex façade designs with control and consistency. The project brings out the importance
of coordination, system selection, and installation quality in achieving a successful outcome.
