EC&I

Addison Project’s control electrical design section has the capabilities and experience to meet your entire EC&I design requirements. We can provide full design teams for multi-million pound projects but also individual designers and engineers can undertake smaller projects or provide a few hours of engineering support. We work to your needs, not our own.

Utilising other departments within Addison Project we can undertake the planning, procurement and management of control electrical construction, placing the emphasis on maximising value. Our team of engineers, designers and detailers can adapt to your specific needs to maintain quality and efficiency levels.Our internal quality procedures ensure that your requirements are understood and fully satisfied whilst considering safety, environmental and constructability issues. Compliance with relevant client and industry standards, regulations and legislation is also under strict control and is one of our highest priorities when completing any project.Our range of EC&I design services include:

P & ID development.
Front-end design and feasibility studies
HV power distribution (upto 33kV) Compliant and registered to NERS
Surveys and reports, including lighting requirements and fire alarm systems
Project cost estimates, from budget to sanction grade
Equipment user requirement specifications
Hazardous area design expertise
Maintenance and inspection of Electrical & Instrumentation (E&I) Equipment in Hazardous Areas.

CDM documentation

HV Engineering up to and inc. 33kv

The continued drive to expand production capabilities can put a strain on the electrical infrastructure and cause anomalies such as tripping and faults.

At Addison Project, we have experienced high voltage engineers who are able to provide support and guidance on any electrical issues up to and including 33kV. This is supported by our Amtech software with which we also have the capability to complete the required load/fault studies to provide substance behind our findings. Our high voltage expertise is accredited to NERS (National Electricity Registration Scheme) which provides us with the opportunity to compete for contestable works associated with the installation of electrical connections with the various DNOs. Our current NERS accreditation includes design and project management:

LV Cable Network to Commercial/Industrial Properties
HV Cable Networks up to 33kV
Substations up to 33kV

Project Management

Cable laying upto 33kV
Cable jointing including LV dead up to and including 33kV
Substation installation up to and including 33kV

This has seen our involvement on some prestigious projects including the new container port in Essex, the London Gateway Project, on which we provided the HV design and engineering to support 22 primary substations. This project was further complemented by our civil and structural design expertise as we were able to offer a full design of the substations from a civil/ structural and electrical capacity which increased efficiency as our client was only dealing with a single design interface.

Our electrical capability also includes the ability to deliver what we plan with our engineers suitably qualified “SAP” (Senior Appointed Persons) available to switch and commission as required.

Review Of Site Electrical Infrastructure

Complemented by our HV capabilities we are able to offer a comprehensive review of site electrical infrastructure to check compliance with recommendations of BS 61936. – 2010 and HSE recommendations for reducing risks and protecting people. This would typically include:

Inspection of all HV* and LV Substations & switch Rooms comprising:-
- Internal and External visual inspection of the building for structural defects.
- Inspection of all safety facilities, i.e. Exits, fire protection, security.
- Check compliance with all HSE requirements for signage in substations.
Inspection of all substation & switch room protection relays with cross-checking against test & inspection records.
Inventory of all switchgear and cross-check against records and drawings.
Verification of switchgear condition, the validity of test and inspection records.
Visual inspection of all substation and switch room earthing systems with cross-checking against test and inspection records.
Visual inspection of all substation transformers, reactors, external switchgear etc, check security fencing, earthing, risks and precautions to personnel and adjacent plant, with cross-check against test and inspection records.
Electrical protection Fault Study for the complete site, using ERACS and Amtech software, with updated drawings and recommendations to rectify any shortfalls.
Complete site Earthing survey with cross-checking of earthing records.
Compile and complete report supported by photographs of all deficiencies, faults etc.
Update, compile and complete drawing package, test records, single line diagrams etc.
