K H Engineering Services were awarded the contract by Bam Nuttall to install all Mechanical and Electrical services to the newly constructed Platform 0. The installation & commissioning of new services were to be installed while maintaining the existing services for the station. The scope of works consisted of the following:
• Relocate / remove existing equipment located at the subway entrance to Platform 0
• Provide new DNO service to station and associated distribution
• Main Switchgear
• Sub main cables and distribution boards
• Final circuit wiring
• Lighting and emergency lighting installation
• Small power installation
• Earthing and bonding
• Installation of Help Point
• Installation of Fire Alarm System
• Installation of interface between fire alarm, emergency lighting, and secondary means of escape.
• Installation of CCTV
• Installation of mechanical services (water) to pre constructed toilet block
• Inspection, testing & commissioning
K H Engineering Services Limited worked in conjunction with Bam Nuttall coordinating initial site investigations and the removal / relocation of services within the subway adjacent the proposed entrance to Platform 0.
A programme of both normal working hours and engineering working hours were agreed as part of the contract, with a final key date of operation set for the 2nd of January 2018 as approved between all parties.
During the course of the contract it become apparent the existing DNO service to the station was insufficient for the additional supply. This information was passed to the client and preliminary designs were completed, however, due to late client approval only 3 months were given to supply a new 400Amp service for the station.
To meet this key requirement an additional labour team was drafted into the project and the programme altered to reflect the changes with the need to meet the key date unchanged.
In addition to the extra works, further programme changes had to be completed due to the late completion by 3rd party contractors on key building structures within Platform 0. This included the canopy structure, waiting room and toilet block all failing to meet the key dates. Due to the above K H Engineering Services Limited made further amendments to the programme and devised a solution of a further team working night shifts in order to regain the lost time.
K H Engineering Services Limited were the responsible contractors for this project and construction responsibility. KHESL were able to complete the project in line with the completion date with no RIDDORS and extensive improvement opportunities presented to the client. KHESL were delighted to report zero defects at practical completion with the final account pre- agreed.
K H Engineering Services Limited managed the interface between UKPN and other contractors to supply a fully functional DNO services within a limited time, allowing the project to meet all required key dates
