Key Features

Heavy-Duty Gantry Crane Infrastructure

A major feature of the facility is its overhead gantry crane infrastructure.

The structural frame was designed to accommodate a 10-tonne overhead gantry crane running the length of the assembly line, supporting the movement of heavy equipment and allowing trucks and containers to be unloaded internally within a weather-protected environment.

A separate 3-tonne overhead gantry crane supports operations within the dedicated 670m² assembly area.

Specialist Assembly & Service Areas

The warehouse extends well beyond conventional storage and incorporates a range of specialist facilities tailored to Hitachi's operational requirements.

Dedicated areas include:

• Robo-wash
• Hot tank wash
• Paint booth
• Weld bay
• Pressing area
• Compressed-air plant
• Assembly areas
• Dispatch and staging zones

Warehouse lighting was upgraded to meet the required lux levels for assembly activities, while ventilation was designed around the operational requirements associated with internal truck unloading.

Safety & Operational Movement

Highly visible internal hard barriers delineate assembly and work areas, specialist booths, warehouse amenities, offices and staging zones.

A dedicated forklift charging area incorporates an epoxy floor finish and protective barrier wheel stops, providing a clearly defined operational zone within the warehouse.

These features demonstrate that the building was designed around how the tenant actually operates, which is an important story for prospective industrial clients.

Solar Energy System

The facility incorporates a 100kW rooftop solar energy system, supported by 130kW inverters and 30kW of battery storage.

The system provides an important energy-efficiency feature within a facility containing substantial warehouse, assembly and specialist operational infrastructure.

Construction Challenges

Programme & Tenant Relocation

The project was delivered within a tight programme aligned with Hesperia's requirements and Hitachi's planned relocation date.

This required careful programming and coordination across construction and specialist fit-out activities to maintain progress towards the required completion timeframe.

Access & Adjacent Construction

The broader Hesperia development involved neighbouring buildings and construction activities within the same precinct.

Access constraints required construction sequencing to be adapted to safely accommodate Shelford's works alongside activities occurring on adjacent projects.

Works were resequenced where necessary to maintain progress while protecting personnel working across the surrounding construction environment.

Complex Services Coordination

Services coordination required significant pre-construction consultation between the project team and numerous consultants.

The challenge was increased by the need to integrate issued-for-construction documentation across multiple buildings, consultants and builders within the broader development.

Detailed planning, coordination and strategic resequencing allowed these interfaces to be managed while minimising impacts on the construction programme.
