Services

Four disciplines. One delivery structure.

Development, construction, project management and design coordination are run together, so decisions taken in one are answered for in the others.

01Service group

Development

From concept and feasibility to a delivered asset.

OTT structures projects around the decisions that determine their outcome: what is viable, what it should cost, how it should be designed and how it will be delivered. Development work runs from early feasibility coordination through design management and budgeting into construction.

02Service group

Construction

Disciplined execution across sectors and scales.

Construction is delivered against defined specifications, method statements and inspection procedures. Scope covers structure, envelope, finishes and external works, with specialist trades coordinated inside a single delivery programme.

03Service group

Project Management

Programme, cost and quality held under one structure.

Projects are managed from pre-construction planning through commissioning and handover. Programme, cost, quality assurance and quality control (QA/QC) and health, safety and environment (HSE) management are treated as one accountable system rather than separate reporting lines.

04Service group

Design Coordination

Integrated design coordination.

OTT coordinates the disciplines that determine whether a project performs successfully, not simply the work occurring on site. Drawings, specifications and specialist input are reconciled before they reach the field, where correction is most expensive.

Design disciplines are delivered through a coordinated structure of in-house management and appointed consultants and specialists, assembled to suit each project.

Procurement runs alongside every service group

Sourcing, technical evaluation, quality control and logistics are carried out by OTT rather than delegated, which is what keeps specification and programme aligned on site.
