New PMC, Technical Customer, EPCM and EPC — a 9-minute breakdown of the four delivery modelsPMC vs Technical Customer vs EPCM vs EPC Read it

Glossary

Glossary: capital project management terms

The same role carries different names depending on the contracting tradition — a local term, an international one, or an English abbreviation. Below are short definitions of the terms that appear in contracts, reports and on this site.

Delivery models and roles

Technical Customer

An organisation that performs the statutory owner's functions on the investor's behalf: permitting, design management, tendering, site supervision and commissioning. It works under an agency model — the client signs the contracts, while the technical customer prepares and polices them and answers to the investor for schedule, cost and quality.

Also called:

owner's engineerowner's project delivery organisation

About the service →

PMC

Project Management Consultant — a company that manages a construction project on the owner's behalf. It neither designs nor builds: it organises and controls those who do, and answers to the investor for schedule, cost, quality and handover. The same role Kazakhstani practice calls the technical customer.

Also called:

Project Management Consultantproject management consultancy

About the service →

EPCM

A model in which one company becomes the single managing contractor across three streams: engineering, procurement and construction management. Unlike EPC, the fee is paid for management while the cost of works and equipment stays open-book to the client.

Also called:

Engineering, Procurement and Construction Managementmanaging contractor

About the service →

EPC

Fixed-price turnkey delivery: the contractor designs, procures and builds, absorbing cost risk. Its economic interest is opposed to the investor's — any saving inside the fixed price becomes its margin — so an EPC project still needs independent quality and quantity control above the contractor.

Also called:

turnkey general contractingEngineering, Procurement, Construction
Managed Service

Buying a single management function instead of the whole owner's role: project controls only, supervision only, procurement or document control only. A rational entry point where a full contract is uneconomic, or where a company has its own team but lacks one competence.

Also called:

discrete management function

Project controls

Project controls

The engineering discipline that answers two questions: when the asset will actually be finished and what it will finally cost. It covers planning and scheduling, physical progress measurement, cost control, change management and forecasting.

Also called:

cost and schedule controlplanning and scheduling

About the service →

Baseline

The approved schedule and budget against which every deviation is measured. Without one, “two months behind” means nothing: there is no reference point. Changes enter the baseline only through a formal procedure.

Also called:

baseline schedulecost baseline

About the service →

Critical path

The chain of activities that determines the project completion date. A delay to any activity on it moves the end of the project by the same amount; a delay elsewhere moves nothing until it consumes that activity's float.

Also called:

CPMcritical path method

About the service →

Earned value

A method comparing three quantities: how much work was planned, how much was actually completed, and what was spent on it. It produces the SPI (schedule) and CPI (cost) indices — a numerical measure of deviation instead of a qualitative judgement.

Also called:

EVMSPICPI

About the service →

Cost to Complete

A forecast of the expenditure still required to finish the project, calculated from actual status. Added to sunk cost it gives the final cost forecast. It is the key figure for a lender because it answers whether the committed facility is sufficient.

Also called:

CTCEstimate at CompletionEAC

About the service →

S-curve

A cumulative curve of earned quantities or cost over time. Comparing the planned, actual and forecast curves shows both the size of the slippage and its trend — whether the project is recovering or continuing to diverge.

About the service →

Rules of credit

The rules by which physical progress becomes a percentage: each unit of work carries a weight and a completion criterion. Without them, percentage complete is declared by eye by the performers and is worthless.

Also called:

progress measurement rules

About the service →

Procurement and contracts

Long lead items

Equipment with a manufacturing and delivery cycle of 6 to 18 months: process lines, transformers, cranes, UPS units, chillers. If these are not identified and ordered early, delivery sets the start-up date and money can no longer accelerate it.

Also called:

LLI

About the service →

Change control

A formal procedure: a change is registered, assessed for cost and schedule impact, approved, and only then carried into the baseline. Without it, additional works are agreed on site and enter payment certificates unpriced.

Also called:

change managementchange register

About the service →

Design

Value engineering

Work on design decisions to reduce delivery cost while preserving the required functional and operational performance. “While preserving” is the operative phrase — it separates value engineering from simply cutting scope. It is worth doing before working drawings are issued.

Also called:

design optimisation

About the service →

Quality and supervision

Technical supervision

Control of compliance between executed work, the design, the codes and the certified quantities, carried out in the owner's interest. It covers incoming material inspection, in-process and acceptance control, covered-works certification and quantity verification before certificates are signed.

Also called:

site supervisionconstruction control

About the service →

Covered-works certification

Inspection and documentary record of work before it is closed by the next layer: reinforcement, waterproofing, foundations, buried services. If work is covered without a certificate the evidence is lost permanently — it can no longer be seen.

Also called:

inspection of covered works

About the service →

ITP

An Inspection and Test Plan lists the control points for each work type with the inspection method, acceptance criteria, required records and responsible parties. It makes acceptance predictable for everyone involved.

Also called:

Inspection and Test Plan

About the service →

Handover and documentation

Commissioning

The management process between “construction is finished” and “the asset is running”: system boundaries, readiness criteria, test sequence, participant coordination and documentation of the result. It is planned during design, not after construction.

Also called:

start-up and handover

About the service →

Punch list

A single register of defects before acceptance, categorised by impact on handover: what blocks it and what is cosmetic. Without that categorisation a team spends equal time closing the critical and the trivial.

Also called:

snag listdefect register

About the service →

As-built documentation

Certificates, logs, test reports and record drawings — evidence of how the work was performed and what was actually built. It cannot be assembled before the acceptance commission: some evidence is physically unrecoverable.

Also called:

site recordsrecord drawings

About the service →

ISO 19650

The international standard for information management on construction projects, defining naming, statuses, revisions and exchange in a common data environment. In practice it removes the single largest source of error — building to superseded information.

Also called:

common data environmentCDE

About the service →

Financing

Lender's technical monitoring

An independent monthly check for a bank or investor: whether the claimed quantities were actually built, whether expenditure matches the budget, and whether the facility is sufficient to completion. Performed by a party with no role in the construction.

Also called:

financial and technical monitoringbank monitoring

About the service →

Technical due diligence

A pre-transaction review of a site or asset: title and encumbrances, development potential, ground conditions, utility connection conditions and cost. It answers what the asset will actually cost, as opposed to its transaction price.

Also called:

pre-acquisition surveysite due diligence

Planning a new project, or needing to stabilise a current one?

Start with a short conversation. If the situation is difficult, start with a project audit: 3–5 weeks, fixed price, an independent opinion.

We reply within 1 business day. A commercial proposal follows within 5 business days of the scoping meeting.
