Meadow Mushrooms upgrade nearing completion

We are very pleased to share that the final project in a large capital works programme for Meadow Mushrooms, which has been running for over 10 years, is in the final stages and due to receive practical completion this month.

Our client, Meadow Mushrooms, is a NZ owned and operated company and New Zealand’s leading mushroom producer. They have five three main sites in and around Canterbury and a team of nearly 500 including composters, growers, harvesters, and packers as well as engineers, quality control and other support staff.

Since 2009 Meadow Mushrooms have been rolling out a large capital works programme to upgrade and expand their facilities. This process has allowed Meadow Mushrooms to migrate all facets of the growing process into newer, more efficient technology, and allow their ageing Prebbleton site to be decommissioned.

Cequent’s work with this client started in 2013 and has included:

- Delivery of an initial 12 new growing room extension

- Development and construction of a new two storey office building

- Construction of a new storage and mixing shed

- Further bulk and location planning along with road and car parking realignment

- Seismic strengthening and upgrades across their Canterbury property portfolio.

The most recent project included the construction of 36 new growing rooms (over two stages). The building has a footprint of 12,868m2 and is 237.5m long by 54.18m wide.

A unique factor to these projects has been the use of a design and build specialist mushroom building company from the Netherlands. Cequent has played an integral role coordinating both the onshore and offshore teams (civil, structural, architectural, services) to ensure a well-coordinated design was provided to the tendering contractors. Subsequently Cequent were appointed the key consultant to manage the integration between the local contractor and subcontractor teams, and specialist installers who were brought in from Europe to install and commission the HVAC and controls equipment.

Extensive enabling works were also required including:

- Installation of temporary services

- Decommissioning of redundant services

- Supply of new mains power to site

- Decommissioning, modification, and construction of new transformers

- Upgrading potable water supply to site

- Demolition of existing buildings and facilities

- Significant ground remediation works, including the removal of 52,000m3 of non-engineered fill, making way for engineered fill to be brought in for construction of a stable building platform

- Creation of 9 additional compost growing tunnels, new spawn & supplement storage rooms, and a lab facility (including associated civil works) at their Giggs Crossing site to increase compost growing capabilities

Congratulations to everyone involved, it has been an incredible journey and we look forward to assisting Meadow Mushrooms with future works.
