    • aircraft stand centre lines, stop bars and air bridge reach
    • dispenser inlet hose reach
    • relevant safety distances
    • location of existing hydrant system Emergency Shut Down stations
  • Report comprising:
    • layout drawings for affected stands plus key issues and proposed solutions
    • engineering definition and scope of work – optimum balance of dispenser and hydrant system modifications with respect to capex and life cycle cost and operational downtime and cost during construction
    • tie-in details
    • budget price for materials and labour to perform the works
  • Detailed Design of the Works including:
    • positioning of additional hydrant pits
    • development of the tie-in methodology
    • programming of the closure of each stand with respect to hydrant system works such that the works could be completed within the tight shutdown time allowed
  • Preparation of the Tender for the Construction Works including:
    • Instructions to tenderers
    • drafting of the Construction Contract and definition of the Technical Requirements including scope of work
  • Quarterly monitoring of progress and quality of the Works
  • HAZOP – as a statutory requirement for the planned construction works
    • preparation of the process
    • chairing of 2 day HAZOP meetings
    • production of formal report
    • administration of action item close out process
  • Completion
    • Review/comment and close-out of documentation and approval on behalf of client
