Definitions of the key terms, standards, and acronyms used in EPCM, pharmaceutical, and food manufacturing engineering. Written by engineers, not a marketing department.
Engineering, Procurement and Construction Management. A project delivery model where the EPCM firm manages the project on behalf of the owner, but all contracts remain in the owner's name. The owner retains full control over supplier selection, costs, and decision-making.
Engineering, Procurement and Construction. A turnkey delivery model where a single contractor designs, procures, and builds the facility. The contractor holds all subcontracts and delivers a finished product for a lump sum.
A project manager who works exclusively for the client (owner), representing their interests against contractors, suppliers, and other parties. Also called Owner's Representative or Client-Side PM.
An engineer or engineering team engaged directly by the client to provide independent technical oversight of a project being delivered by contractors. Reviews designs, witnesses tests, and protects the owner's technical interests.
Current Good Manufacturing Practice. Regulations enforced by agencies like the FDA and EMA that govern the design, monitoring, and control of manufacturing processes and facilities for pharmaceutical products.
Hazard Analysis and Critical Control Points. A systematic food safety management approach that identifies biological, chemical, and physical hazards in production and designs engineering controls to prevent them.
Critical Control Point. A step in a food production process at which control can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level. Must be monitored by engineering controls.
A qualification framework used in pharmaceutical engineering where each design specification (URS, FDS, DS) is mirrored by a corresponding qualification protocol (PQ, OQ, PQ). Ensures every requirement is tested and every test traces back to a requirement.
User Requirements Specification. The top-level document in the V-model that defines what the system must do from the user's perspective. All subsequent design and qualification activities trace back to the URS.
Functional Design Specification. Describes how the system will function to meet the URS requirements. Validated against during Operational Qualification (OQ).
Design Specification. The detailed technical specification for equipment or systems. Validated against during Installation Qualification (IQ).
Factory Acceptance Test. Testing performed at the equipment manufacturer's site before shipment to verify the equipment meets its design specification. When structured correctly, FAT evidence can serve as IQ documentation.
Site Acceptance Test. Testing performed after equipment installation at the client's site to verify it operates correctly in its installed environment. Typically feeds into OQ evidence.
Installation Qualification. Documented verification that equipment and systems are installed according to the approved design specification. The first qualification stage after installation.
Operational Qualification. Documented verification that equipment operates within specified parameters under all anticipated operating conditions. Tests functional performance against the FDS.
Performance Qualification. Documented verification that the equipment consistently performs as intended under actual production conditions, meeting the requirements defined in the URS.
Good Automated Manufacturing Practice, version 5. A risk-based framework for the validation of computerised systems in the pharmaceutical industry. Published by ISPE. Covers SCADA, DCS, MES, LIMS, and ERP systems.
Computer System Validation. The documented process of ensuring that a computerised system does exactly what it is designed to do in a consistent and reproducible manner, as required by regulatory frameworks like EU GMP Annex 11 and FDA 21 CFR Part 11.
International standard for cleanroom classification. Defines air cleanliness classes (ISO 1 through ISO 9) based on particle concentration. Used in pharmaceutical manufacturing to classify cleanrooms as Grade A, B, C, or D.
Food Safety System Certification 22000. A GFSI-benchmarked food safety certification scheme based on ISO 22000 and sector-specific prerequisite programmes. Required by many food retailers and manufacturers.
Brand Reputation Compliance (formerly British Retail Consortium). A GFSI-benchmarked food safety standard widely used in Europe. Audits cover facility design, HACCP, allergen management, and hygienic engineering.
International Featured Standards. A GFSI-benchmarked food safety standard used primarily in Germany and France. Similar scope to BRC but with different audit methodology.
European Hygienic Engineering & Design Group. Provides guidelines for the hygienic design of food processing equipment and facilities. EHEDG certification is the gold standard for equipment that contacts food products.
Clean-in-Place. Automated cleaning of equipment and pipework without disassembly. Critical for food and pharma facilities. Requires validated flow velocities, chemical concentrations, temperatures, and contact times.
Sterilise-in-Place. Automated sterilisation of equipment and pipework using steam, typically at 121°C for a defined hold time. Used in pharmaceutical and aseptic food manufacturing.
ATmosphères EXplosibles. EU directives governing equipment and protective systems for use in potentially explosive atmospheres. Relevant for chemical, pharmaceutical, and food dust processing facilities.
A capital project within or adjacent to an existing operating facility. Brownfield projects are more complex than greenfield because they must be coordinated around live production, existing utilities, and operational constraints.
Validation Master Plan. A high-level document that defines the qualification and validation strategy for an entire facility or project. Required by EU GMP and sets the framework for all subsequent IQ/OQ/PQ activities.
Design Qualification. Documented verification that the proposed design of a facility, system, or equipment is suitable for its intended purpose and complies with applicable regulatory requirements. Performed before procurement.
Health, Safety and Environment. The management discipline covering workplace safety, occupational health, and environmental protection during engineering and construction projects.
Mechanical, Electrical and Plumbing. The building services scope of a construction project, covering HVAC, power distribution, lighting, water, drainage, fire protection, and related systems.
Piping and Instrumentation Diagram. A detailed engineering drawing showing all piping, equipment, instrumentation, and control systems in a process plant. The primary document from which construction and commissioning work is executed.
Process Flow Diagram. A high-level engineering drawing showing the main process streams, equipment, and operating conditions in a plant. Developed before the P&ID and used to define the process basis for design. Typically includes mass and energy balances.
Hazard Identification. A structured, facilitated review conducted at concept or early design stage to identify significant hazards associated with a facility or process. Outputs are logged in a hazard register and used to inform the design brief before detailed engineering begins.
Hazard and Operability Study. A systematic, structured review of a process design — typically conducted at detailed design stage against the P&IDs — to identify deviations from design intent that could create safety or operability problems. Action items must be closed before construction begins.
Water for Injection. The highest-purity grade of water used in pharmaceutical manufacturing, required for parenteral products and equipment cleaning in sterile facilities. Produced by distillation or membrane filtration. Distributed hot (70°C+) or cold under validated conditions.
Project Execution Plan. The master governing document for a capital project, defining scope baseline, organisational structure, work breakdown structure (WBS), schedule, budget, risk management approach, and key decision gates. Written before execution begins and updated at major project milestones.
Work Breakdown Structure. A hierarchical decomposition of the total project scope into manageable work packages. Used as the basis for scheduling, cost control, and responsibility assignment. Each element in the WBS maps to a cost code and schedule activity.
A graphical representation of cumulative project expenditure or progress plotted against time. The characteristic S-shape reflects slow spend at the start (mobilisation), rapid spend during peak construction, and tapering off at close-out. Used to detect early divergence between planned and actual spend.
The rate at which a project is spending its budget over a given period, typically reported weekly or monthly. Compared against the planned S-curve to detect overruns or underruns early. A burn rate significantly above or below plan is an early warning signal requiring investigation.
A live project document recording identified risks, their probability and impact, assigned mitigation owner, and current status. Should be reviewed at every project review meeting — not created at the start and filed. An unreviewed risk register provides no protection.
A formal record of all scope changes on a project, including the originator, description, cost and programme impact assessment, approval authority, and outcome. Under EPCM, every contractor variation passes through change control before the client approves it — preventing scope creep from accumulating undetected.
A project schedule showing activities at the work package level, typically with 2–6 week durations per activity. The primary execution tool for tracking progress, identifying the critical path, and managing float. More detailed than a Level 1 (milestone) or Level 2 (phase) schedule.
The sequence of project activities that determines the earliest possible project completion date. Any delay to a critical-path activity delays the whole project by the same amount. Float is the amount of time a non-critical activity can slip before it joins the critical path.
Non-Conformance Report. A formal record raised when work, materials, or equipment do not meet the specified requirements. Each NCR requires a root cause, corrective action, and sign-off before the affected work proceeds. On GMP projects, open NCRs cannot be carried into the next qualification stage.
Inspection and Test Plan. A document defining all quality hold points and witness points for a construction or installation scope. Hold points require the client or engineer to sign off before work proceeds. Witness points require notification. The ITP is the primary quality control tool on site.
A list of outstanding defects or incomplete items identified during a commissioning or handover inspection. Categorised as A (must be resolved before system handover) or B (can be resolved after handover within an agreed timeframe). No system should be released for operation with open A-items.
Engineering drawings updated to reflect what was actually constructed, as opposed to what was originally designed. Redline markups collected from contractors during construction are reconciled and reissued as the as-built record. Essential for future modifications, maintenance, and regulatory inspections.
The point at which all physical construction and installation work is complete and the system is ready for pre-commissioning. Marked by a mechanical completion certificate, a completed punch list (A-items closed), and handover from the construction team to the commissioning team.
A pre-qualified list of suppliers assessed against defined technical, commercial, and quality criteria. In GMP projects, the AVL includes GMP capability assessments. Procurement should only go to tender with suppliers on the AVL — using an unqualified supplier bypasses a critical quality control.
A structured comparison of supplier bids against the technical specification and commercial terms, presented in a matrix format. Enables objective, auditable comparison of multiple bids. The basis for a procurement recommendation — the cheapest bid rarely wins when technical compliance and delivery risk are properly weighted.
Active monitoring and management of supplier manufacturing progress to ensure on-time delivery against the project schedule. Includes factory visits at key manufacturing milestones, document submission tracking, and early escalation when deliveries are at risk. Often the difference between a project that delivers on time and one that doesn't.
