EPCM: engineering, procurement and construction management in one contract
Under EPCM, INVECON acts as the single managing contractor: we organise engineering, procurement and construction and answer for the outcome of all three streams. The client retains control of key decisions and full budget visibility.

In substance
What EPCM is
EPCM is chosen when the client has no in-house construction organisation and the project is too complex to split into dozens of unconnected contracts. Unlike fixed-price EPC, EPCM does not turn the manager into a seller of construction: the fee is paid for organisation and management, while the cost of works and equipment stays visible to the owner. INVECON does not work under EPC as a matter of policy — we manage projects from the owner's side.
When you need this service
A complex industrial or infrastructure project
Process equipment, long-lead deliveries, multiple work fronts and a tight construction sequence.
No in-house construction organisation
The client is a manufacturer or investor for whom construction is not the core business.
A one-off project with high uncertainty
There is no direct precedent, scope firms up as design progresses, and a fixed EPC price is either unattainable or heavily loaded with contingency.
Dozens of contracts with nobody managing them
Designers, equipment vendors, works contractors and commissioning teams — without a management layer, the interfaces between them become the delay.
Cost transparency is required
The investor needs to see the real cost of equipment and works, not a single lump-sum figure.
What we do
E — Engineering
Design brief, selection of design houses, documentation release schedule, interdisciplinary coordination, expert review, value engineering, design change control.
P — Procurement
Procurement strategy, long-lead item identification and early ordering, equipment and works tenders, bid evaluation, contract award, vendor inspections and FAT, logistics and delivery control.
CM — Construction Management
Contractor and work-front coordination, construction schedule, site supervision, quality and HSE management, as-built control, change order minimisation.
Controls across all three streams
One integrated E-P-C schedule, cost control and final cost forecasting, risk register, interface management, owner reporting.
Commissioning and handover
Commissioning plan, system readiness, test support, punch list, statutory commissioning and handover of the full documentation set.
Deliverables
Deliverables
The specific documents, reports and management products that remain with the client.
Integrated E-P-C schedule and approved project budget
Construction-ready design documentation with a positive expert review
Procurement strategy and plan, long-lead register with award dates
Contract pack for design, supply and construction works
Commissioning records, punch list, commissioning certificate, as-builts and handover dossier
Client outcomes
One accountable party
The client no longer manages the interfaces between designer, vendor and contractor — the EPCM contractor does.
Synchronised streams
Engineering, procurement and construction run to one schedule: equipment is ordered against design decisions and arrives against installation readiness.
An open budget
Equipment and works costs remain visible; the management fee is separated from construction cost.
Minimal client involvement
The owner takes key decisions and receives reporting instead of running daily coordination.
FAQ
Frequently asked questions
Not answered here? Write to us and we will respond on your case.
EPC is fixed-price turnkey delivery: the contractor absorbs cost risk, prices contingency into the lump sum and is motivated to reduce its own cost. EPCM is management of engineering, procurement and construction for a fee: the cost of works and equipment stays open-book, a larger share of cost risk remains with the owner, but the conflict of interest disappears and the owner gains real control over the quality of decisions.
PMC and Technical Customer work under an agency model — the client signs the delivery contracts. Under EPCM, INVECON becomes the single managing contractor that organises engineering, procurement and construction itself and answers for all three. It is the highest-responsibility format in our portfolio.
Design management and its outcome sit with the EPCM contractor: we set the brief, select the design house, review the documentation, run constructability review and value engineering, and manage expert approval. The design organisation's own professional liability remains within its contract.
Two base schemes apply: a percentage of CAPEX, or a team rate with a performance bonus tied to schedule and budget. The model is fixed after scoping — the range of functions, team composition and project duration.
Design is delivered inside the consortium: Prime Design, a first-category licensed design organisation, is part of INVECON. For the client this remains a single accountability stream within the EPCM contract.
