The brief

In response to an increase in demand for their products, Hagley Windows & Doors found themselves in need of additional production and storage space. Consequently, they sought to expedite the design and construction process for the required extension.

What we did

We provided comprehensive design and construction services for a new workshop, featuring overhead cranage and a two-storey office block. The design incorporated various elements, such as concrete slab foundation, steel portal frames with cross bracing, precast concrete wall panels, and suspended concrete floors. Additionally, steel beams supported gantry cranes, and the office block included precast concrete wall panels, steel cross bracing frames, and rib and infill flooring.

For structural independence and to account for any potential seismic activity, the new building was located adjacent to an existing workshop, with a seismic gap between them to prevent load transfer during earthquakes.

The project was executed in three stages – foundations, superstructure, and architectural and services design. The initial foundation stage allowed for early construction commencement while the final design was being completed.

Initially designed to support one five-tonne gantry crane, the plan was adapted based on the client’s operational requirements, allowing for the installation of a second five-tonne gantry crane to enhance operational efficiency.
