Hallamshire Business Park

The Problem

A specialist window contractor was required to service and repair almost 1,000 Aluminium Windows across three floors of two office blocks in central Sheffield.

The window systems installed were obsolete and direct replacement parts were no longer available. We were asked if we could adapt other hardware on the market or source replacement fit for purpose parts from our supply chain where possible. Such was the nature of the existing hardware, that this meant a world-wide search to find the relevant parts.

Project Overview

Hallamshire Business Park provides a total of approximately 65,000 sq ft of good quality, purpose-built office accommodation, arranged in two blocks of approximately 20,000 sq ft and 45,000 sq ft respectively.

No.1 Hallamshire Business Park comprises a 3-storey prestigious ‘Headquarter’ office building, which is capable of being subdivided and let on a floor-by-floor basis or in two separate wings. The property benefits from an impressive entrance and spacious reception area, located centrally between the two wings.

No.2 Hallamshire Business Park comprises a 3-storey office building of a similar style and specification to No.1. This building is also capable of being subdivided on a floor-by-floor basis.

In 2016 we were asked to support Jennor UK with their tender to refurbish the building and create a new office environment by quoting for all window related repairs. The contract award was made in 2017.

We carried out a full survey of all existing windows to identify faults and produce a programme of works. These works included the replacement of double glazed units, gaskets, handles and hinges to return all windows to a fully operational state, and a limited amount of new replacement windows.

Nature of the works

The windows were aluminium, side hung casement windows of a style no longer in production and the key challenge was sourcing replacement parts.

This required a great deal of investigation by our in-house technical team to identify suitable suppliers and parts to enable the contract to be completed.

One example of this was where the gaskets needed to be sourced to match other existing gaskets which were to be retained. In the end we worked with our supplier to extrude a bespoke gasket in a dedicated RAL colour to match the site requirements.

The contract also required new restrictors to be fitted to all second-floor windows. These products were not readily available on the market but we eventually sourced a supplier in New Zealand and the parts were ordered up.

Closer to home was the need to find a supplier for a limited number of replacement windows to replace some of the existing ones which were damaged beyond repair, and which were no longer readily available in the market.

Working with the contractor, what we did was to identify a number of windows that were no longer going to be required after the building remodelling, so these were used to replace the damaged ones – recycling in action. This still left two to be replaced. A Sheffield based supplier was found who manufactured a bespoke fixed window almost identical to the 20-year-old window that we were replacing.

Throughout the project we were required to work alongside other contractors which we did successfully. Our engineers were among the first people onsite and among the last to leave. The final job we completed was to change the Threshold on the aluminium entry doors.
