Integrated Preconstruction Support

Build the Service Scope Around the Project Requirement

A project may need one specialist service or several connected preconstruction disciplines. The service scope can therefore be structured around the required project outputs.

This can include technical drawings, BIM models, estimates, quantity takeoffs and supporting documentation before construction.

Preconstruction Outputs

What Can Be Included in the Project Scope?

The final deliverables depend on the selected service. A project can include one output or a combination of technical deliverables.

BIM Models Modeling outputs for the agreed project scope.
CAD Drawings 2D and 3D drawing documentation.
Cost Estimates Estimate outputs based on the defined scope.
Quantity Takeoffs Measured quantities for selected project trades.
Construction Documentation Project documentation for agreed technical requirements.
Data Center Deliverables Defined BIM, estimating and preconstruction outputs.
Project Sectors

Preconstruction Support Across Major USA Project Types

The current USA service scope includes support for commercial, residential, industrial and infrastructure projects.

Commercial Office, retail and mixed-use projects.

USA Preconstruction Workflow

How Can a USA Preconstruction Scope Move From Project Files to Deliverables?

The process can start with available project information, then move through scope definition, technical production, review, revisions and final delivery.

Project Setup

Start With the Information Available for the Project

A project can begin with drawings, models, specifications, BOQs, markups or other available project information. The required service scope can then be defined.

Drawings Architectural, structural or MEP information.
Models Available BIM or digital model information.
Specifications Relevant technical project requirements.
BOQs & Quantities Existing quantity or estimating information.
Markups Comments, redlines and revision information.
Required Outputs Define the requested project deliverables.

The required workflow can vary by service, project stage and available information.
Project Workflow

A Structured Path From Scope Review to Delivery

The exact sequence depends on the selected service. However, a multi-service project can generally follow these stages.

01 Review Project Information Review the available files, disciplines and requested outputs.
02 Confirm Service Scope Define which BIM, CAD, estimating, takeoff or documentation services apply.
03 Prepare Technical Outputs Develop the agreed models, drawings, quantities, estimates or documentation.
04 Review Against the Scope Check the prepared outputs against the agreed project information and deliverables.
05 Incorporate Agreed Revisions Update applicable project outputs from supplied comments, markups or revised information.
06 Prepare Final Deliverables Organize the agreed project files for final delivery.
Multi-Service Handoff

Connect Related Preconstruction Workstreams

When several services are included, the outputs from one workstream can provide information for another where the project scope requires it.

BIM → Coordination Model information can support defined coordination reviews.
CAD → Documentation CAD drawings can form part of the required documentation package.
Drawings → Takeoff Available drawings can provide the basis for defined quantities.
Takeoff → Estimating Agreed quantities can be used within the defined estimating scope.
Revisions → Updates Updated project information can be incorporated into applicable outputs.
Data Center Scope Data center projects can combine BIM, estimating and other preconstruction requirements.
Project Review

Review Outputs Against the Agreed Requirements

The review stage should focus on the information supplied, the selected service scope and the agreed deliverables.

Project information
Defined discipline scope
Requested deliverables
Supplied revisions
Revision Management

Update Relevant Outputs as Project Information Changes

Where revisions are included in the agreed scope, applicable drawings, models, quantities or documentation can be updated from supplied project changes.

Redline updates
Drawing revisions
Model updates
Quantity updates
Scalable Outsourcing Support

Structure Support Around Project Demand

Preconstruction support can be arranged for a defined task, a larger multi-service project or an ongoing outsourcing requirement.

Defined Task One selected preconstruction requirement.
Single Project Support around a defined project scope.
Multi-Service Scope Several connected preconstruction disciplines.
Ongoing Support Recurring requirements across multiple projects.
Workflow Basis

The actual workflow, review stages, revision cycles and deliverables depend on the selected service, project information and agreed scope.
