ENGINEERING PROJECT PROFILE
COTTAM POWER STATION


As a main supply chain partner, Jilland Engineering Limited has undertaken the following packages in the prestigious FGD project at Cottam Power Station.

Pump Houses 2 and 3
These steel framed buildings consist of approximately 650 tonnes of structural steelwork. The structures house and support the main induction fans, pumps and ductwork for the absorber process. The buildings were supplied complete with access stairs, floored areas, hand railing and sheeting rails. Pump House 2 also incorporates a lift shaft which accesses seven levels from ground to the top of absorbers 2 and 3.

As our remit is one of complete “Turnkey”, Jilland Engineering Division provide detail design and manufacture of all structural elements (through our in-house Fabrication Plant), application of high spec paint systems and full erection, including cranage, all internally sourced through our Erection and Plant divisions. Moreover, as a fully compliant Engineering Contractor, Jilland Engineering Division have managed all quality aspects of the project by the application of our ISO 9001:2000 accredited management systems, ensuring our “right-first-time” ethos is fully maintained.

The Waste Water Treatment Building
A steel structure consisting of 350 tonnes of structural steelwork, this building was built in two stages. The first stage, up to 15m level, allowed the civil contractor to complete concreting works and thus permitted installation of two pre-assembled belt filters prior to the roof structure being erected. This eastern europe map flexible approach to programme sequencing and problem solving management is actively encouraged within Jilland, and ensures that the needs of the project are at the forefront of our management philosophy.

ENGINEERING PROJECT PROFILE

COTTAM POWER STATION
The Mill Building

A steel structure consisting of 160 tonnes of steelwork, built around two
pre-erected ball mills. All the structures are connected with substantial Pipe
Bridges and again, the entire package has been detailed, manufactured and
erected by Jilland Engineering Division.

The Limestone Silos Cones
Jilland Engineering Division were contracted to site assemble, site weld and weld test two silo cones complete with support rings weighing 75 tonnes each and measuring 16 metres in diameter. Once pre-assembled, Jilland Engineering Division supervised contract lifts into the concrete silos and positioned the silo cones ready for final welding.

With our current portfolio of works nearing completion, Jilland Engineering Division remain actively involved in the tender process for the remaining packages of structural steel and mechanicals work, and we remain committed to providing engineering excellence to the principal contractor RWE for the life of this project and beyond.

RAIL PROJECT PROFILE

McNICHOLAS RAIL LIMITED
FTN 2 - Areas 47 and 64

As part of the National Fixed Telecoms Network Programme, Jilland Rail Division was employed as the sole contractor to the principal, McNicholas Rail and Laing O'Rourke on areas 47 & 64 and 35 & 63 respectively.

With full responsibility for the execution of the entire portfolio of works,
Jilland Rail Division has provided an 80 strong workforce, including all site management and safety critical staff to undertake:

• Surveys
• Vegetation Removal
• Civil Route Installations
• Fibre and Copper Joint Bays
• Loc Bases and Hard Standings
• Cable Installation - Fibre and Copper

Both Projects were successfully completed on budget and with no incidents or accidents.

 

STRUCTURAL SERVICES PROJECT PROFILE

CHIMNEY DEMOLITION AT WEST BURTON
Client: EDF Energy (West Burton Power) Limited

In October 2003 we were awarded a contract for the demolition of two 183 metre high, single flue, brick lined reinforced concrete stacks at West Burton Power Station, Nottinghamshire. Our two demolition teams, working on both stacks simultaneously, have to date removed approximately 150 Tonnes of internal steelwork, 800 cubic metres of brick lining and 1900 cubic metres of concrete, with separation of asbestos contaminated material as necessary.

To achieve this performance level we have used our frame mounted hydraulic breakers. Initially jacked into position at the top, they “climb down” the structure, breaking up and removing the concrete windshield. In this instance, due to stability constraints on the stack, it is removing the lining too. The breaker frame is adjustable, allowing it cope with the changes in diameter as the demolition proceeds. Accompanying the breaker frame is an external suspended platform which is also adjustable. This provides an enclosed access deck for our personnel assisting the breakout operation, and also acts to contain the concrete debris.

The platform is serviced by an Alimak construction hoist allowing easy access by both our own and our client’s personnel.

Periodically, the accumulated spoil is removed from the base of the stack and transported to an onsite tip. Once the stack is within reach of ground based demolition machinery then the remaining stub will be removed by more conventional means.

This project was the largest mechanical demolition ever undertaken in the UK and was successfully completed ahead of schedule and within budget.

FABRICATION PROJECT PROFILE
The Fabrication Plant provides bespoke manufacturing services to the Engineering, Construction and related sectors.

Of the more impressive fabrications recently manufactured are 30 Cruciform Columns up to 17.5m long made from 533x210 JB’s with Tees welded both sides of the web for the full length with complex plated connections at three places along the length. Many of these floor beams are made from plate girders manufactured within the Fabrication Plant.

Another recent projects have involved;

  • The manufacture and supply of electrostatic precipitator steelwork
    sections for Environmental Elements USA contract at Corus Works
    Port Talbot, South Wales. Approximately 450 tonnes have been
    fabricated, shotblasted, painted and transported to site.
  • The supply of steelwork for four Fossil Fuel Power Station Magnox
    Emission Systems, total weight of 2000 tonnes
  • The supply of steelwork for two major incinerator plants in the
    South of England, approximate weight of 1600 tonnes.

In parallel with the larger contracts, we are currently manufacturing small packages for other valued clients such as McNicholas Rail, Rugby Cement, Lodge Sturtevant, Robinson Structures Limited and FLS MILJO.

All our work is undertaken by skilled craftsmen, certificated to and in accordance with all the latest British Standards and the National Structural Steelwork Specification 4th Edition.
