Expertise / Delivery Models

Design & Build, with one team accountable.

OCL brings design coordination, procurement and construction together around the project brief. We can also enter at other stages, from early contractor involvement to construction from completed documentation.

Our primary approach

From brief to a building ready for use

Design & Build gives the client a coordinated path through design, buildability, procurement and construction, with OCL responsible for bringing the work together.

Construction input from the start

We work with the client and consultant team to test performance requirements, services interfaces, construction sequencing and costs before decisions become difficult to change on site.

  • One coordinated programme and delivery team
  • Early buildability and procurement advice
  • Structure, services and specialist fit-out coordination
  • Construction, commissioning and handover

How we engage

The right model for each project

Design & Build is a core capability. OCL can also join earlier as an adviser or deliver construction against an established design.

Main Contractor / General Contracting

Disciplined programme, trade, quality and site management against a consultant-led design.

Construction Only

Efficient construction delivery from completed documentation, with practical site coordination and reporting.

Early Contractor Involvement (ECI)

Buildability, sequencing, procurement and cost advice while the design is still being developed.

Turnkey Project Delivery

An integrated path from early planning to a completed, operational facility ready for use.

Design & Build process

One coordinated path from brief to operation

Early construction input keeps performance requirements, buildability, procurement and programme aligned before work reaches site.
