As a cost management practitioner working on large-scale infrastructure and hyperscale data centre projects, I have seen first-hand how critical equipment packages can significantly influence programme certainty and project risk.
Equipment such as generators, switchgear, cooling infrastructure and uninterruptible power systems often requires manufacturing lead times of several months and represents significant capital investment in a project.
Under traditional procurement models, these packages are typically supplied by the contractor or its subcontractors.
However, in certain circumstances owners may elect to procure these items directly from manufacturers while the contractor remains responsible for installation and integration within the works. This is known as owner-furnished contractor-installed (OFCI) procurement.
This article provides an introduction to the OFCI process, explaining how the model operates, the potential benefits it can provide in terms of programme certainty and cost control, and the risks that project teams must carefully manage to ensure successful implementation.
How does OFCI work?
OFCI procurement is a delivery model in which the project owner procures specific equipment or materials directly while the contractor remains responsible for installing and commissioning those items as part of the construction works.
The OFCI process typically begins during the design development or early procurement phase, when the project team identifies equipment packages suitable for owner-led procurement.
These decisions are usually informed by several factors, including programme constraints, supply chain availability, equipment standardisation requirements and life cycle considerations.
Once these packages have been identified, the owner undertakes the procurement process directly with equipment manufacturers or suppliers. This may include vendor selection, commercial negotiation, contract award and manufacturing oversight.
Meanwhile, the contractor continues to manage the construction programme and remains responsible for ensuring that the equipment can be integrated into the building works.
Once the equipment is on site, the contractor takes responsibility for installation, system integration, testing and commissioning.
Because procurement and installation responsibilities are divided between parties, clear contractual interfaces are essential.
These typically address:
- delivery and logistics responsibilities
- storage and preservation requirements
- installation coordination
- testing and commissioning procedures
- warranty allocation.
When implemented effectively, OFCI allows owners to maintain direct control over critical equipment while leveraging the contractor's expertise in installation and system integration.
Benefits and saving mechanisms
Long manufacturing lead times can represent a major risk to construction programmes. By procuring critical equipment directly and early in the project life cycle, owners can initiate manufacturing well before site construction begins.
This provides greater control over the supply chain and reduces the risk of problems with equipment availability delaying the overall programme.
Another advantage lies in greater commercial transparency. Direct procurement allows owners to engage with equipment manufacturers without layers of subcontractor mark-ups, which may lead to more competitive pricing for the owner.
In projects involving multiple facilities or programmes of work, this approach can also enable framework agreements and bulk purchasing, generating additional cost efficiencies.
OFCI procurement can also support equipment standardisation across multiple assets.
For organisations operating portfolios of facilities such as data centres or healthcare networks, standardising key equipment can simplify maintenance, reduce spare parts inventory and improve operational reliability.
Additionally, direct relationships with equipment suppliers provide owners with clearer visibility of warranties, technical documentation and maintenance requirements, improving long-term asset management after handover.
In the construction of hyperscale data centres, for example, these advantages are particularly evident.
The availability of critical infrastructure components such as backup generators, uninterruptible power systems and electrical distribution equipment can dictate the entire programme schedule.
Direct procurement by the owner enables these components to be manufactured in parallel with construction planning, significantly reducing delivery risk.
However, while OFCI can generate efficiencies, its success relies heavily on effective coordination between project stakeholders.
Pitfalls and the potential for increased costs
Despite these advantages, OFCI procurement also introduces a number of challenges that must be carefully managed.
One of the most significant issues relates to interface management between the owner, contractor and equipment supplier.
As the contractor is responsible for installation but not procurement, there may be limited contractual control over supplier performance.
Delays in manufacturing or shipping can therefore affect the construction programme while falling outside the contractor's direct control.
Logistics management can also become more complex. Responsibilities for transportation, customs clearance, on-site delivery and storage must be clearly defined.
Failure to properly manage these aspects can lead to damage, warranty disputes or additional costs associated with handling and preservation.
Another potential risk involves design coordination. If contractors are not adequately involved during equipment procurement, compatibility issues may arise between the selected equipment and the building systems into which it must be integrated. This can result in redesign or programme delays.
There is also the possibility that administrative costs associated with managing procurement, supplier relationships and logistics may offset some of the financial savings achieved through direct purchasing.
Furthermore, under OFCI arrangements the owner assumes a greater share of procurement risk.
In traditional procurement models, the contractor bears responsibility for supplier performance and delivery. With OFCI, this risk allocation shifts partially to the owner.
For these reasons, successful implementation requires clear contractual frameworks, early contractor involvement and strong project governance.

Where is OFCI most applicable?
OFCI procurement is not suitable for every project, but it can provide significant advantages in projects where critical equipment plays a central role in programme certainty, operational performance or life cycle asset management.
The approach is particularly well suited to projects such as data centres, healthcare facilities, laboratories and complex infrastructure projects, where specialised mechanical and electrical systems form a large proportion of the project's value.
Specialist equipment needed for hyperscale data centre developments often has lead times exceeding six months.
Direct procurement allows owners to secure these components early and maintain consistent technical standards across multiple facilities.
Similarly, healthcare projects frequently involve specialised equipment that must meet strict performance and compliance requirements.
OFCI allows owners to maintain control over these specifications while ensuring that installation is coordinated through the contractor's construction programme.
Ultimately, the effectiveness of OFCI depends on the capability of the project team to manage supply chains, coordinate stakeholders and clearly define contractual interfaces.
When implemented with strong governance and collaboration between owners, contractors and suppliers, OFCI procurement can offer a strategic solution for managing risk, improving programme certainty and delivering high-performance built assets.
