Engineering, Procurement & Construction (EPC)

Successful projects depend on more than good engineering or efficient construction in isolation. They require engineering decisions, procurement strategy, vendor performance, logistics, constructability and field execution to work as one system. APD provides an integrated EPC delivery model designed to reduce interface risk, improve execution certainty and maintain clear accountability from project definition through completion.

Our teams coordinate multidisciplinary engineering, procurement and construction activities around the project’s technical requirements, schedule, budget, safety obligations and operational objectives. Whether the scope is a new facility, plant expansion, brownfield modification, infrastructure package or a defined EPC work package, our focus is practical engineering, disciplined execution and a safe, efficient transition into operation.

Integrated EPC Delivery from Concept to Commissioning

Engineering & Design

We develop engineering solutions that are technically robust, constructible, cost-conscious and aligned with the intended operating environment. Engineering is managed with close attention to design interfaces, regulatory requirements, operability, maintainability and lifecycle performance.

  • Concept development and feasibility support
  • Front-End Engineering Design (FEED)
  • Basic and detailed engineering
  • Multidiscipline design coordination — process, mechanical, piping, civil/structural, electrical and instrumentation/control
  • 3D modelling, BIM/VDC coordination and design reviews
  • Constructability and maintainability reviews
  • Value engineering and design optimisation
  • Technical specifications, datasheets, drawings and material requisitions
  • Engineering support during procurement, construction and commissioning

Procurement & Supply Chain

Our procurement approach connects technical compliance with commercial discipline and delivery requirements. We manage the purchasing cycle from requisition through vendor documentation, expediting, inspection, logistics and site delivery, helping clients maintain visibility over critical materials and equipment.

  • Procurement planning and package strategy
  • Supplier and vendor prequalification support
  • RFQ/RFP administration and techno-commercial evaluation
  • Bid clarification and commercial negotiation support
  • Purchase order and subcontract administration
  • Vendor document coordination
  • Inspection, quality surveillance and source expediting
  • Manufacturing progress monitoring
  • Logistics, freight and delivery coordination
  • Material tracking and site receipt coordination

Construction & Field Execution

APD converts approved engineering into controlled field execution through structured planning, competent supervision and strong HSE and quality management. Work is sequenced to protect critical path activities and to coordinate civil, structural, mechanical, piping, electrical and instrumentation interfaces.

  • Site establishment, mobilisation and construction planning
  • Civil, structural and architectural works
  • Mechanical equipment installation
  • Piping fabrication, erection and tie-ins
  • Electrical and instrumentation installation
  • Constructability and maintainability reviews
  • General contracting and specialist subcontract coordination
  • Site supervision and field engineering
  • QA/QC inspection and test coordination
  • Construction progress measurement and reporting
  • Mechanical completion, punch-list management and handover support

Commissioning & Handover

  • Pre-commissioning and commissioning planning support
  • System and subsystem turnover coordination
  • Mechanical completion dossiers and handover documentation
  • Punch-list close-out coordination
  • Start-up readiness support
  • As-built and final documentation close-out
