    Shetland Islands Council




    Construction of cold store facility


    320kw Low temp cooling

    Temporary Cold Storage in Scotland; The Temporary Fish Market Project in Scalloway, Shetland.

    ACR were very proud to have been chosen to carry out this strategic project for Shetland Island Council. This project was a slow burner from the-off, with multiple visits to the Island, many options were discussed until the final solution was arrived at. Happily, our visits were always a pleasure, Shetland is a great place with wonderful landscape and great people.

    The challenge;

    To supply a full turnkey cold storage facility to house the existing fish market whilst the existing site was re-developed.  The project length was proposed at 18 months.

    Major factors discussed were the suitability of locating a building externally on the quay and the feasibility of building a structure of some sort in an existing warehouse. The latter was chosen as the best option due to the risk of high winds blowing down a traditional aluminium “A” framed building.

    The market area was to maintained at 3 degrees for fish storage after sale before transportation.

    A full specification for the building was specified by the consultants Arch Henderson

    The Solution;

    A suitable building on the quay was identified. With a large clear span area it was ideal. We recommended building a modular steel framed “box” insulated with 50mm sandwich panels. Designed carefully, it it gave the largest internal floor plan available from the existing warehouse.

    Cooling would be supplied by 4 independent cooling systems, each comprising of a 80kw chiller and 50kw low temperature ahu. A key advantage of stand alone systems is that there is no single point of failure. It was calculated that 2 systems would maintain the temperature.

    With a limited 100A supply to the building generation was specified, again, for 100% redundancy, twin tandem running sets were specified.

    The Result;

    This project was built on time and on budget. At the time of writing this, the project has been on-going for 19 months.

    No significant problems have been encountered, and to everyone’s surprise, even the porters who work the market like it, which we have been told is praise indeed (apparently they are very outspoken)

    The Customers Thoughts;

    from Andrew Sanderson BSc (Hons) PG Dip CEng FICE FIES, Arch Henderson LLP

    “Shetland Islands Council needed to build a new fish market at Scalloway Harbour for the busy fishing industry, however, it could only be built on the same site as the original. This meant a temporary facility was required during the demolition and construction process.

    Arch Henderson LLP who had been appointed as lead consultant for the project looked at various options, and consulted with ACR on chilling methods. It was decided that the most sensible and cost-effective solution was to rent an existing warehouse and install a 750m2 chilling facility to keep the fish fresh.  However, the warehouse needed insulation and therefore it was decided to build a steel framed insulated envelope within the warehouse which could create a suitable space for the market operations with an insulated barrier between the outer walls and roof of the warehouse.

    Following a competitive tender process ACR Ltd was selected to install the temperature controlled envelope and chillers in the temporary market facility which was completed on time and on budget.

    After completion of further environmental and food hygiene aspects, Shetland Islands Council now has a temporary fish market facility that will continue to serve the fishing industry and raise revenue for the Council, whilst the new fish market is built. ACR Ltd now co-ordinate and provide ongoing servicing and maintenance of the facility which is expected to be in place for around 16 months”


    Facility has now been used for two markets on two consecutive weeks with no issues to date.
