Project intelligence from estimate to close-out.

Seven connected disciplines combine cost certainty, real-time project visibility, and independent commercial advice.

Professional construction

The GEMS way.

Our quantity surveying and project-control services use proven industry practice and GEMS data systems to make project cost, progress, and risk easier to understand and act on.

01

Quantity surveying

Cost management, project planning, and tailored advice. GEMS streamlines tender-document preparation to improve accuracy and efficiency.

What we do

The decisions behind successful delivery.

Our work connects the commercial baseline to the live project, helping teams protect value as scope, progress, and risk evolve.

01

Cost estimating

Accurate estimates with meticulous detail and proactive risk management.

02

Project planning

Objectives, controls, and risk strategies shaped for complex energy work.

03

Construction progress

Live task, resource, and bottleneck visibility across project delivery.

04

Commercial value

Defensible baselines, cost efficiency, change control, and objective advice.

05

Risk management

Early risk identification, targeted mitigation, and data-backed decisions.

How we work

A clear path from uncertainty to control.

Each engagement is shaped to the project, while the underlying discipline remains consistent.

01

Understand

Align scope, data, stakeholders, and the commercial question.

02

Model

Build a defensible cost, schedule, or risk baseline.

03

Control

Track real progress and expose material variance early.

04

Close

Resolve commercial obligations and leave a clear audit trail.
