EPCM places engineering, procurement and construction management under a single contract and a single technical authority. The client keeps the construction contracts and sees every vendor and subcontractor cost. +NR runs the engineering baseline, the procurement packages and the site coordination against that baseline, with one change control board and one performance measurement baseline from detailed engineering to start-up.
You hold the construction contracts and see every vendor and subcontractor cost.
One technical authority and one engineering baseline run the whole project, from detailed engineering to start-up. Scope can still move, because nothing is locked in a lump sum.
Detailed design is issued as construction packages, and procurement runs against the same engineering baseline. Vendor data returns to the configuration register through change control, so the specification and the purchased equipment do not drift apart.
Procurement runs on the same baseline. Vendors are inspected at their yard, and their data comes back through change control.
The client holds the construction contracts. +NR coordinates subcontractors technically and commercially on the client's behalf, keeps engineers at site to resolve changes at the asset, and stays through commissioning with the same team that produced the design.
Cost, schedule and quality are reported against one performance measurement baseline, on a monthly cycle, with the same granularity as the engineering scope. Contract models are chosen with the client to match its risk appetite and contracting standards.
Health and safety run under ISO 45001 at site, process safety is built into the design, and every non-conformance goes through change control.
Pre-start-up safety review, performance tests and handover by the same team
The people who made the design answer the questions on site.
How +NR runs EPCM programmes: contract structure, cost control, vendor data, site measurement and continuity.
Under EPC a single contractor takes the construction contracts and the associated price risk, and the owner buys a finished plant. Under EPCM the owner holds the construction contracts and +NR manages engineering, procurement and construction on the owner's behalf. The owner sees every vendor quote and subcontractor price, keeps the ability to change scope without renegotiating a lump sum, and carries the schedule and quantity risk with +NR reporting against a baseline. EPCM suits brownfield work and projects where scope will move; EPC suits well-defined scopes where price certainty matters more than visibility.
The project is controlled against one performance measurement baseline, set when detailed engineering starts. Contingency is assigned to identified risks rather than a flat percentage, and every cost line traces back to a scope item. Change orders are quantified before approval, and the monthly performance pack shows earned value, variance and forecast to completion at the same granularity as the engineering scope.
Procurement packages are issued from the same specifications that detailed design is built on. When a vendor returns certified data, it enters the configuration register through the change control board, which checks the effect on interfaces, layouts and downstream disciplines before the data is accepted. Inspection and test plans are agreed with the vendor at award and followed at the supplier's yard.
Against installed quantities taken from the engineering quantities, verified by field engineers at site. Invoiced amounts are reconciled to those quantities, never the other way round. Variance against the construction baseline is raised at the change control board with quantified recovery options. Health and safety at site is managed under ISO 45001 together with the client's own standards.
The discipline leads who produce the detailed design follow the equipment through procurement and are present at site during commissioning. The risk register, interface register and change log opened at the start of detailed engineering are the same documents used at handover. Questions raised during pre-start-up safety reviews are answered by the people who made the original design decisions.
