Hollinwood Junction

Industrial
“This contract builds on our extensive industrial portfolio and our experience in delivering high-quality industrial developments with strong sustainability credentials. We’ll be implementing materials, construction methods, and operational systems to achieve a BREEAM excellent rating. The development will deliver meaningful change for Oldham, and we’re pleased to support that by mobilising our team now, so the benefits of this commitment start flowing immediately.” Chris Harper, Pre-construction Director for Russell WBHO

Facts

13 new shell warehouse units with associated ancillary office accommodation, arranged across five blocks

Site Constraints & Remediation

The site contains a disused gas holder and two known mineshafts, both requiring remediation. The gas holder must be dewatered prior to grouting; based on the permitted discharge rate from United Utilities, this process will take approximately six weeks. To accelerate the programme, we consulted with our specialist mineshaft grouting contractor and agreed to deploy a second pump during grout operations.

Following successful grouting, a capping solution will be implemented over the mineshaft collapse zones to ensure long-term ground stability.

Pre-Construction Investigations

During the pre-contract Letter of Intent (LOI) period, extensive site investigations were undertaken to inform a robust Remediation Strategy and discharge pre-commencement planning conditions. These included:

  • Soil sampling
  • Water sampling from the gas holder
  • Ground-penetrating radar (GPR) surveys for existing services
  • Japanese knotweed removal
  • Trial excavations to confirm the exact location of the United Utilities water main and mineshafts

Remediation & Groundworks Strategy

A comprehensive Remediation Strategy was developed to enable efficient cut and fill operations across the site. With the exception of surplus topsoil and green waste, no material will be removed from site. Excavated materials will be cement-stabilised and reused as engineered fill. All remediation works will be verified and signed off by our geotechnical consultant.

Sustainability Measures

In line with our commitment to sustainable construction, the scheme incorporates multiple carbon-reduction and energy-efficiency features, including:

  • Photovoltaic (PV) panels
  • Electric vehicle (EV) charging points
  • Leak detection systems
  • Low-energy lighting and smart controls
