Current Contracts

Core Drilling Specialists Ltd are now reaping the rewards of some very prestigious drilling and sawing contracts within the construction industry and the controlled demolition industry. For example, The Forth Road Bridge, where major sawing works was required to enable resurfacing of the Bridge and The Rosyth Royal Dockyard where Core Drilling Specialists Ltd coped with and successfully completed on schedule - the largest Diamond Core Drilling contract in Great Britain. The Rosyth contract included 600 No. 800mm diameter holes, 1.6 Meters deep at an angle of 26 degrees. These holes were to allow anchors to be fitted to the dock walls of the entrance loch as means of strengthening.

Parliament House, Edinburgh

The Scottish Court Service appointed Interserve to manager the first of three phases of a £63 million pound programme to refurbish the historic Parliament House building, home to the Court of Session, in Edinburgh.

Interserve will undertake a package of maintenance and improvement work to the value of £12.3 million which will see the replacement and upgrading of essential services to the building including electrical wiring, water pipes, heating, cooling and ventilation systems, fire systems and lifts.

The works also include the modernisation of two of the twelve civil courtrooms to include the upgrading of IT facilities and new judicial chambers.

In further phases of the project, the majority of the other courtrooms will be modernized with improvements to security, building links, jury and witness facilities, judicial chambers and office accommodation.

Parliament House is a collection of buildings on one site ranging over six floors. The oldest building - Parliament Hall- is approaching 400 years old and is on record as dealing with civil cases in the 1700s. Some of the courtrooms are listed.

An earlier project to redevelop Parliament House announced in 1999 was put on hold after the completion of an initial phase, which delivered new library accommodation and a limited, upgrading of judge’s chambers. Ministers announced a review in December 2004 because it was feared the programme could take up to 14 years to complete and that costs could rise to £200 million.

The new contract reduces the scope of the redevelopment and delivers in three separate phases. These measures reduce the overall costs and timescales substantially.

C.D.S were successful at tender stage, they were chosen from a large sub-contract tender list. The selection period was not based soley on costs but also a combination of the how they carry out work and their previous experience. C.D.S demonstrated that they were the perfect company for the job through the previous refurbishment of Parliament House, which C.D.S were also sub-contracted to carry out structural alterations etc.

CDS are involved with three different packages e.g. downtakings, builders work and structural alterations. Phase one is split into two sections, PSA Building and the Bank Building.

C.D.S stripped out all levels of old walls, floor finishes, ceiling finished, old furniture and redundant services in both buildings which had to be carried out during normal working hours and after with minimum disturbance to the court services as the building still had to function during the works. C.D.S also created door openings through one and a half meter thick walls using specialist cutting machinery such as wire saw and wall saws. There was also large ducts being fitted through all levels which had to pass through the existing slab, this task was carried out using core drilling and sawing to reduce the hazards such dust, fumes and HAV. This was carried out prior to the necessary trades fitting the areas with new finishes. C.D.S cut all the service holes in both areas in conjunction with Arthur McKay whom were responsible for re- routing the new services throughout both areas of phase 1for electrical and mechanical works.

C.D.S have completed Phase one and have had good feedback form Interserve and are hopeful that we can assist with phase 2 in similar fashion.

Phase two is due to commence on 2nd July 2009.
