Quantity surveying
Cost management, project planning, and tailored advice. GEMS streamlines tender-document preparation to improve accuracy and efficiency.
Discuss this service ↗Services
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.
Estimating
Precise cost assessments built from project requirements, materials, labour, equipment, risk, opportunity, and market movement.
Discuss this service ↗Benchmarking
GEMS-based comparison of cost, time, quality, and safety metrics to reveal strengths, gaps, and realistic performance opportunities.
Discuss this service ↗Contract management
Legal protection, cost control, risk mitigation, stakeholder collaboration, and clear adherence to contractual obligations.
Discuss this service ↗Project control
Real-time collection and analysis that turns project progress into clear, actionable management insight.
Discuss this service ↗Risk and uncertainty analysis
Structured workshops, probabilistic cost modelling, and feedback reporting that quantify schedule and final-cost exposure.
Discuss this service ↗Commercial close-out
Contractual, financial, and administrative close-out managed as one disciplined transition to minimise post-construction delay.
Discuss this service ↗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.
Cost estimating
Accurate estimates with meticulous detail and proactive risk management.
Project planning
Objectives, controls, and risk strategies shaped for complex energy work.
Construction progress
Live task, resource, and bottleneck visibility across project delivery.
Commercial value
Defensible baselines, cost efficiency, change control, and objective advice.
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.
Understand
Align scope, data, stakeholders, and the commercial question.
Model
Build a defensible cost, schedule, or risk baseline.
Control
Track real progress and expose material variance early.
Close
Resolve commercial obligations and leave a clear audit trail.
