Preconstruction support can combine modeling, drafting, quantity, estimating and documentation requirements within a defined project scope.
Integrated Preconstruction Support

Build the Service Scope Around the Project Requirement

A UK project may require one specialist service or several connected preconstruction disciplines. The scope can therefore follow the required project outputs.

This can include BIM models, CAD drawings, construction estimates, quantity takeoffs and supporting project documentation.

Preconstruction Outputs

What Can Be Included in the Project Scope?

Final deliverables depend on the selected service and supplied project information. A scope may include one output or several connected deliverables.

BIM Models Modeling outputs for the agreed project scope.
CAD Drawings 2D and 3D technical drawing documentation.
Cost Estimates Estimate outputs for the defined scope.
Quantity Takeoffs Measured quantities for selected project trades.
Project Documentation Documentation for agreed technical requirements.
Project Sectors

Preconstruction Support Across UK Project Types

The current UK service scope includes commercial, residential, industrial and infrastructure projects.

Commercial Office, retail and mixed-use project requirements.
Residential Multi-family, apartment and residential project scopes.
Industrial Industrial and production facility requirements.
Infrastructure Transport and infrastructure project requirements.
Scope Basis

Preconstruction outputs are prepared from supplied project information and the agreed service scope. Final design decisions, statutory approvals, code compliance and construction responsibility remain with the responsible project professionals.

UK Preconstruction Workflow

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

The working sequence depends on the selected service, project information and agreed outputs. A defined process helps organise inputs, preparation, review and delivery.

UK preconstruction project information and technical documentation review
A project scope can begin with the information currently available and be defined around the required technical outputs.
Project Setup

Start With the Available Project Information

The initial review can use the project files supplied for the selected service. The exact inputs vary by project stage and required deliverables.

Drawings
BIM Models
Specifications
BOQs & Quantities
Markups & Redlines
Required Outputs
Typical Project Sequence

A Defined Six-Step Preconstruction Workflow

The sequence can be adapted to the selected BIM, CAD, estimating, takeoff or documentation requirement.

01 Review Project Information Review the supplied files, project stage and available technical information.
02 Confirm the Service Scope Define the required service, disciplines, outputs and agreed project requirements.
03 Prepare the Deliverables Develop the agreed models, drawings, quantities, estimates or documentation.
04 Review Against the Scope Check prepared outputs against the supplied information and agreed service requirements.
05 Incorporate Agreed Revisions Update deliverables when agreed comments, redlines or revised project information are supplied.
06 Issue the Agreed Outputs Provide the deliverables in the agreed format for the defined project scope.
Multi-Service Handoff

Connect Related Preconstruction Workstreams

Where several services are required, project information can move between related workstreams within the agreed scope.

BIM → Coordination Model information can support coordination requirements.
CAD → Documentation Drawing outputs can support technical documentation requirements.
Drawings → Takeoff Supplied drawing packages can form the basis of quantity takeoff work.
Takeoff → Estimating Defined quantities can support the agreed estimating scope.
Redlines → Updates Agreed markups can be incorporated into revised project outputs.
Multiple Disciplines Connected service requirements can be structured within one project scope.
Scope Review

Prepared outputs can be reviewed against the project information and deliverables defined for the service.

Agreed Revisions

Where revisions form part of the agreed requirement, updated information or comments can be incorporated into the deliverables.

Scalable UK Support

Structure Support Around the Current Project Demand

Preconstruction outsourcing can be structured around a defined task, one project, multiple services or recurring project requirements.

Defined Task Support one clearly defined technical requirement.
Single Project Add support around one project package.
Multi-Service Scope Combine BIM, CAD, estimating and takeoff requirements.
Ongoing Support Structure recurring support around continuing project demand.
The workflow shown above is a general project sequence. The actual process, review stages and deliverables depend on the agreed scope and supplied project information.
