Addison Project were approached by our client to complete a +- 10% sanction grade FEEP for this project. The project involved the construction of a second production line including the specification of the equipment needed and the civil works associated with the housing of this and a potential future production line.
Understanding the difficulties in liaising with the site landlords and the distribution network operators (DNO) they engaged Addison to complete the design and build of the substation on a turnkey basis. The substation was a primary substation, 11kV 7.5 MVA. During the FEEP our clients worst fears were realised when an existing substation was put out of action following a fire.
Addison had the knowledge and experience to overcome this by installing an external temporary HV substation within 2 weeks minimising disruption. The temporary substation had to be positioned not to impede the repair of the existing substation or construction of the new substation.
Addison were appointed to conduct a FEED to ascertain the cost to build a new primary substation building complete with switchgear and associated equipment. Once sanctioned Addison provided a turnkey package for the build with all civil structural, electrical design, specification of equipment, project management, procurement and construction management provided in house. Our role also covered the commissioning of the switchgear and attending of FAT which was completed in house by our engineers.
