• Topographical and land surveys of the proposed pipeline route • Geotechnical investigations to map the subsoil conditions along the route • Final environmental impact and regulatory assessments of the route • Submit drawings for the regulatory approvals required • Assist with the land acquisitions, expropriations of the Rights of Way or servitudes required for the proposed route. The BEP will specify the standards and procedures to be used on the project. For a pipeline and compression stations the following are relevant: • ASME B31.8 – 2014 Edition “Gas Transmission and Distribution Piping Systems” as well as ISO 13623 -2009 – Petroleum and Natural Gas Industries, Pipeline transportation systems. • ASME B31.3 – 2014 – “Process Piping” • API 5L – 45 th Edition “Specification for Line Pipe” • API 1104 – 2013 21 st Edition “Standard for Welding Pipelines and Related Facilities” • API 6D – 24 th Edition “Specification for Pipeline Valves” • ASME B16.5 – 2013 Edition “Pipe Flanges and Flanged Fittings NPS 1/2 Through NPS 24” • ASME B16.9 – 2012 Edition “Factory-Made Wrought Butt-welding Fittings” • NACE SP0169-2013 (formerly RP0169) “Control of Ex- ternal Corrosion on Underground or Submerged Steel Pipelines” • Electrical Codes – British Standards, CENELEC, IEC, ISO, NEMA • Instrument Codes – ISA, API RP 551, IEC, NEMA

• Environmental, health and safety (HSE) requirements • Local content, community relations and training of the local workforce • Security • Detailed engineering • Coordination and cooperation with other company contractors • Management of changes • Project controls and administration • Quality management • Contractor-provided offices, facilities and services to company’s project team • Procurement, sub-contracts and material management • Construction • Contract work phases • Phase 1 – detailed engineering design • Phase 2 – procurement • Phase 3 – construction • Phase 4– pre-commissioning, commissioning, testing, start-up and handover to owner • Pre-commissioning general • Commissioning and start-up assistance • Support requirements for commissioning • Level and quantities of personnel for commissioning • Performance guarantee • Interface responsibility definition • As-built documentation • Final documentation and asset register • Completion of work. If the decision is to move ahead, the consultant will start the engineering phase and issue contracts to the sub- contractors to produce:
