PROJECT Overview
The Bracknell Office Complex is a ten‑storey commercial building in the centre of Bracknell, supporting a high daily footfall and relying heavily on its triplex lift group to maintain efficient vertical transportation for tenants and visitors.
With the existing equipment approaching obsolescence, the building owners commissioned Acute Elevators to deliver a full modernisation programme that would enhance performance, improvereliability, and ensure long‑term compliance with current lift standards.

PROJECT SUMMARY
The modernisation centred on replacing the ageing lift motors, control systems, and associated electrical infrastructure with a suite of high‑performance components designed to meet the demands of a busy office environment. New Ziehl‑Abegg traction motors were selected for their efficiency, smooth operation, and proven reliability in high‑duty applications. These were paired with Kollmorgen MPK4 controllers, providing advanced drive capability, precise levelling accuracy, and enhanced fault‑diagnostic functionality. Drako ropes were installed to ensure optimal traction and long‑term durability, while new Langer & Laumann door operators were introduced to deliver faster, quieter, and more reliable door performance across all landings.
The electrical supply serving the lift group was upgraded to support the new drive technology, improving system stability and resilience.Together, these upgrades significantly reduced downtime, improved energy efficiency, and extended the operational life of the lift group while aligning the building with modern regulatory expectations and tenant service requirements.
PROJECT Introduction
Acute Elevators were appointed to assess the feasibility and scope of a full modernisation of the existing triplex lift group. The lifts form the primary vertical transportation system within the building, supporting continuous movement across all six floors and playing a critical role in the daily operation of the site. The client required a solution that would not only replace outdated equipment but also deliver a measurable uplift in performance, reliability, and energy efficiency.
A detailed survey of the motor room, shaft configuration,and electrical distribution confirmed that the existing arrangement could accommodate modern equipment without structural alteration. This allowed the project to focus on integrating new high‑performance components within the existing footprint, ensuring minimal disruption to building users while delivering a substantial improvement in system capability.
Challenge
The modernisation presented several technical challenges.The existing lift group was operating on ageing motors and outdated control technology that no longer met the demands of a high‑traffic office environment. The electrical supply was not designed to support modern variable‑frequency drive systems, and the client required the works to be completed with minimal disruption to a fully occupied building.
Integrating new motors, controllers, ropes, and door operators within the constraints of the existing shaft and motor room required careful engineering. The equipment needed to be capable of sustained peak‑time usage, deliver smoother and more efficient operation, and comply with current safety and performance standards. No single off‑the‑shelf package could meet all these requirements, so a tailored combination of components was selected to ensure compatibility, resilience, and long‑term serviceability.
Upgrading the electrical supply added further complexity, requiring close coordination between engineering, electrical, and operational teams to ensure the new systems could be installed, tested, and commissioned safely while maintaining access for building users.
Solution
A comprehensive modernisation solution was developed,centred on the installation of Ziehl‑Abegg high‑efficiency traction motors, chosen for their robust duty capability and smooth, energy‑efficient performance. These were paired with Kollmorgen MPK4 controllers, providing advanced control logic, improved ride quality, and enhanced diagnostic capability to support proactive maintenance and reduce downtime.
Drako ropes were installed to ensure optimal traction andlong‑term reliability, complementing the new motor and controller arrangement. To improve door performance—a key factor in lift reliability—new Langer & Laumann door operators were fitted, offering faster opening and closing speeds, quieter operation, and improved resistance to wear.
The building’s electrical infrastructure was upgraded to support the new drive systems, ensuring sufficient capacity and improved stability. All new components were engineered to fit within the existing motor room and shaft footprint, avoiding the need for structural modifications and ensuring a seamless integration with the building’s existing layout.
The combined solution delivered a future‑proofed lift group capable of meeting contemporary performance expectations, reducing energy consumption, and providing a significantly improved user experience.
Result
Following a series of coordination meetings with the client,the final specification was agreed and a clear programme established. All newmotors, controllers, ropes, door operators, and electrical components weredesigned, verified, and manufactured within a 16‑week production window, ensuringthe project remained on schedule.
Installation works were completed over an 8‑weekperiod. Throughout this time, Acute Elevators maintained a strong on‑sitepresence, conducting regular inspections and issuing structured progressreports to provide full transparency and reassurance. These updates ensured theclient had continuous visibility of programme adherence, technical milestones,and any operational considerations affecting the building.
Once installation was complete, a full programme of testing,commissioning, and verification was carried out, with all tests witnessed bythe client. The modernised lift group met all compliance requirements,delivered the expected performance improvements, and aligned fully with AcuteElevators’ quality standards.
The project was delivered within the original programme, andthe dedication and professionalism of the Acute Elevators team were recognisedand appreciated by the client.
