Construction & Delivery Support That Builds the Project You Approved
Engineering oversight through construction and commissioning on a live industrial site, so the savings, performance and operability you designed and approved are what actually gets built, not quietly eroded on site.
- Protects the engineering intent from approved design through to handover
- Reviews submittals, controls changes and walks down systems against the design
- Prepares and witnesses commissioning, not as an afterthought
- Verifies performance on operational data, not just that it was installed
- Part of SHV Energy
- ISO 50001
What This Service Is
Construction and Delivery Support is the phase where EM3 stays actively involved after the design is complete, making sure the project is actually built correctly on a live industrial site. By this stage the project has passed through feasibility, design and tendering; equipment is being ordered, contractors are on site, and installation is about to start or already underway.
Our role here is not to design again, and not to act as the contractor. It is to protect the engineering intent and make sure what is being built matches what was designed, technically and operationally. That means supporting the construction manager and contractors, responding to design queries, reviewing submittals, managing changes, and making sure installation decisions do not quietly erode the expected energy savings, performance or operability. This work happens inside a live plant, where production is often running, utilities are critical and downtime is expensive, so the service exists to control how the project is delivered, not just what gets built.
The Challenge It Solves
The client already has an approved project: the business case is signed off, contractors are engaged, and capital is committed. The risk at this point is not what to do, it is that what gets built will not match what was approved.
That risk shows up in specific ways. Contractors optimise for cost or speed and start deviating from the intended design. Submittals come in that technically work but reduce efficiency or performance. Design queries pile up on site and decisions are made quickly without fully understanding the long-term impact. Coordination between mechanical, electrical, controls and automation teams becomes fragmented. Commissioning is treated as a final step rather than something that needs structured preparation. If this phase is not controlled properly, the project still gets delivered, but the energy savings are lower than expected, the systems are harder to operate, performance drifts and the original business case weakens, often only discovered after handover, when fixing it is expensive.

How EM3 Delivers It
Design control during construction
We review contractor submittals, respond to design RFIs, support procurement clarification, and make sure any change is understood in terms of its performance impact before it is accepted, so the design intent is never quietly eroded.
Engineering-integrity project support
We support project management linked to engineering integrity: cost-control awareness, monitoring progress against the intended plan, reviewing installation against the P&IDs and drawings, and walking down systems as they are installed to confirm they match the design intent.
Commissioning strategy
As the project progresses, we prepare and support the commissioning strategy, defining commissioning protocols, reviewing how tests will be executed, and making sure the right checks are in place before systems are energised.
Active commissioning
During commissioning we attend activities, witness key tests, review the results and confirm the system is behaving as expected. We track issues, produce snag lists, and verify that problems are resolved properly rather than worked around.
Handover and performance verification
After installation and testing, we support handover by reviewing system performance using operational data, confirming whether the expected savings and functionality are actually being achieved. This closes the loop between design intent and real-world operation.
What You Receive
Reviewed and approved submittals
Construction submittals reviewed and approved against the design, so what is procured and installed matches the intent.
A record of design decisions
Records of design clarifications and the decisions made on site, with their performance impact understood and documented.
Walkdowns and snag lists
Walkdowns of installed systems aligned with the P&IDs, plus tracked and prioritised snag lists, so issues are caught and closed out rather than buried.
Witnessed tests and protocols
Witnessed test results and completed commissioning protocols that confirm the system was tested properly, not just energised.
A final engineering reconciliation
A final reconciliation of the project from an engineering and delivery perspective, including recommendations and confirmation of how the system should be operated.
Verified performance
Confirmation, using operational data, that the system is performing as intended, not just that it was installed correctly.
Proven Outcome
On an air-handling-unit upgrade at a pharmaceutical site, EM3 provided ongoing design support through construction and commissioning to make sure the installed system matched the intended energy-saving design. That included supporting equipment specification during procurement, guiding contractors during installation so the design intent was maintained, and providing commissioning support to ensure the system delivered the expected savings.
Without that involvement, construction choices could have quietly deviated from the intended performance and reduced the projected savings. That is the value of the service in a single line: keeping the project that gets built the same as the project that was approved, and proving it on the data once it is running.
Why EM3
Construction is not a handover point
The same engineering team that understands the design and the business case stays involved through delivery, so decisions made on site are judged against the original performance intent, not just whether installation is possible.
Independent of contractors and vendors
Our independence lets us challenge decisions that may reduce performance or long-term value, without being influenced by procurement or delivery pressures.
Commissioning as core, not an add-on
We focus on how systems behave in real operation, not just whether they are installed correctly, which is why commissioning and performance verification are treated as core parts of delivery.
The loop is closed
We use operational data to confirm the system performs as designed, connecting the original intent to the real-world result rather than assuming installation equals performance.
How We Engage
Frequently Asked Questions
Are you the contractor, or are you designing the project again?
Neither. We protect the engineering intent: making sure what gets built matches what was designed, by supporting the construction manager and contractors, reviewing submittals and controlling changes, without designing again or taking the contractor's role.
Why does this phase need engineering oversight?
Because the risk shifts from what to do to whether what gets built matches what was approved. Contractors optimise for cost and speed, submittals can reduce performance, and fast on-site decisions erode savings. Uncontrolled, the project is delivered but the business case weakens.
What do you do during commissioning?
We prepare the commissioning strategy and protocols, witness key tests, review the results, track and resolve snags properly rather than working around them, and confirm the system behaves as expected before and after it is energised.
How do you confirm the savings are real?
We use operational data after installation to verify the system is performing as intended, not just that it was installed. That closes the loop between the design intent and the real-world result.
Can you work on a live plant?
Yes. This work happens inside live plants where production is running and downtime is expensive. Controlling how the project is delivered in that environment, safely and without disruption, is exactly the point of the service.
How long are you involved?
Across the construction and commissioning phase, from site mobilisation through installation to commissioning and handover, usually as repeated site visits and ongoing support rather than a single engagement.
