Muirdykes WTW – Scottish Water

We are providing a full design and installation service on behalf of Black & Veatch ( main contractor ) for a new water filtration / treatment facility at Muirdykes north of Glasgow. Value of our installation package is circa £850k. The installation is well underway and scheduled to come on line summer 2017.

Deephams

The joint venture AMK have awarded Interface Contracts the main LV cabling package for Deephams WWTW. With a value to Interface of £ 2.2M, the scope of work involves the detailed design, supervision and installation of building services and main cabling associated with ASP lanes, FST’s, PST’s, storm pumping stations and CHP plant. The work is scheduled for completion late summer 2017. Our total scope of work included 11000volt cabling to several transformers, the secondary cabling from the transformers to LV switchboards and the associated earthing. Additionally we designed and installed containment throughout the project to accommodate the power, control, instrumentation and profibus cabling.

Port of Tyne

A materials handling plant comprising of 1Km of conveyors transporting biomass ( wood chip fuel pallets ) to Lynemouth power station. Our early engagement by Spencer Group involved developing a 3D model that identified the cable containment routes and building services supports. Due to the complexity of the conveyor systems and the restricted area / space to work within, the development of the model helped tremendously to determine the most suitable routes that would allow access to install , but also to maintain at a later stage.

Interface’s design team worked closely with Spencers team to ensure all disciplines could be accommodated on the structure. To assist in this, we developed jointly, a system whereby large sections of the work could be prepared in modular form at ground level before lifting in to place. Our scope of work consists of power, control and instrumentation cabling. Status signal cabling and a full building services design and installation throughout the conveyors and the associated administration and ancilliary buildings are also part of our scope. The plant is scheduled to come on line in late summer 2017.

Edina Engines

Interface Contracts have been involved with Edina for several years now, providing a turnkey electrical design and installation package for their gas engine powered generators. The projects provide a huge range of diversity in scope and can vary from £ 3k to £ 500k. The schemes involve our usual combination of 11000volt cabling through to telemetry and the full building services comprising of lighting, small power, lightning protection, fire alarms and intruder alarms.

Glasgow Waste Recycling Facility – Viridor

This project with a sub contract value in excess of £10M is our largest project to date. Sub contracted to Interserve Construction whom we worked very closely with to develop the coordinated 3D model. Our scope of work after we had designed the project in 3D involved 11000volt cabling, power , control and instrument cabling throughout the plant.The project covered a wide range of working conditions ranging from confined spaces, working at height, Compex installations and profibus commissioning.

We also supplied and installed a complete trace heating system to all exposed process piework.

Sandon Dock, Liverpool

Interface Contracts has won praise for being “proactive under difficult circumstances” from GCA after being called in to refurbish BAFF cells at Liverpool WwTW’s Sandon Dock.

Peter Brett of GCA emphasised the degree of difficulty faced by Interface in the £3 million contract as it had “come in dribs and drabs.”

Describing Interface as “being very much part of the overall team”, he added:

“They were very proactive and that helped tremendously. They really played their part in the success of the project.”

Liverpool WwTW which was built on the old Sandon Dock – and is still most often referred to by that name – faced a major problem in that the cells in its BAFF plant had begun to fail.

The answer lay in automating the system which controls the flow of water through the D screens into each cell at what was the first ever treatment works to serve Liverpool and Bootle, so ending the wastewater discharge directly into the River Mersey.

GCA, the main contractor, called on Interface to refurbish the BAFF cells. This involved an Interface team of four dealing with flow meters, level switches and actuated valves on each cell along with modification to the DH+ communication network between each of the BIOFOR control panels.

Activities included the preparation of BCDs, loop diagrams, tray routing diagrams along with the installation itself and testing the actuated valves.

Working entirely on cable containment, this required some 60 to 70 meters of scaffolding to enable the Interface team to work at the height of 5 meters around the BAFF plant.

GCA called on Interface to initially handle six BAFF cells, then extended the contact for the remaining eight cells along with a package called the X works.

“The job was completed in line with GCA’s schedule, no dates were missed and the contract was completed within budget,”
says Paul McCreery, the Interface Project Manager.
