Quantity Surveying – ANTERHILL Consultancy

Measuring Value. Managing Cost. Protecting Outcomes.

Quantity Surveying from Concept to Completion

Construction cost is never simply a number.

It is the consequence of design decisions, quantities, specifications, procurement strategy, market conditions, programme, resources, risk, contractual obligations and the way a project is ultimately delivered.

ANTERHILL provides integrated Quantity Surveying services across the full project lifecycle, combining rigorous measurement and cost intelligence with commercial judgement to help clients and contractors make informed decisions, control expenditure and protect value.

From early feasibility and cost planning through procurement, tendering, construction, change management and final accounts, we bring together the technical discipline of quantity surveying with the wider commercial realities of project delivery.

Our approach is grounded in internationally recognised quantity surveying principles and aligned, where applicable, with professional frameworks and measurement standards including RICS New Rules of Measurement (NRM), RICS Code of Measuring Practice, International Property Measurement Standards (IPMS) and the International Cost Management Standard (ICMS).

This Means Asking Not Only

Why does it cost
this much?

What is driving
the cost?

What alternatives
exist?

What are we
committing to?

What could
change?

What value are
we receiving?

Better Questions.
Brighter Outcomes.

Quantity surveying is more than measurement

Accurate measurement is fundamental, but measurement alone does not create commercial value.

We connect quantities and costs with the wider project context—design development, procurement, programme, construction methodology, market conditions, risk, contractual mechanisms and project objectives—to give clients a more complete understanding of the financial implications of their decisions.

01 Feasibility & Development

Before a project becomes a design, it needs a financial framework.

We help clients establish the cost implications of development options and understand the relationship between land, design, construction, financing, programme, risk and expected value.

Our Capability Includes:

Development appraisals
Preliminary cost estimates
Order of cost estimates
Project feasibility analysis
Construction cost assessments
Cost benchmarking
Preliminary cash-flow assessments
Option appraisal
Procurement strategy advice
Risk allowances
Value management
Value engineering
Whole-life and life-cycle cost considerations

02 Design Economics & Cost Planning

Keeping design ambition aligned with financial reality.

Design development can create value—or quietly consume it.

We establish and maintain cost plans throughout design development, testing design decisions against budgets and helping project teams understand the cost consequences of changes before they become commitments.

Our approach considers:

Design development
Elemental cost planning
Cost benchmarking
Unit rates
Market conditions
Inflation
Location factors
Currency fluctuations
Construction methodology
Risk and contingency
Value engineering
Value management
Life-cycle costing
Whole-life costing
Capital and operating costs

The objective is simple:

Design what is required. Understand what it costs. Optimise what it delivers.

03 Measurement & Quantification

Precision begins with measurement.

We provide detailed measurement and quantification of construction works to support estimating, cost planning, procurement, tendering, contract documentation, interim valuations, change management and final accounts.

Our teams can measure from conventional drawings and specifications as well as from digital models, extracting structured information to support quantity and cost analysis.

Our capability includes:

Quantity take-off
Elemental measurement
Detailed measurement
Composite quantities
Floor-area measurement
Functional-unit measurement

Measurement verification

04 BIM-Enabled Quantity Surveying

When the model becomes a source of cost intelligence.

Quantity surveying is increasingly connected to digital engineering. We integrate BIM with quantity surveying processes to improve the relationship between design information, quantities and cost. This does not replace professional measurement and commercial judgement. It strengthens them.

Our capability can include:

BIM-based quantity extraction
Model-based measurement
Model interrogation
Quantity validation
Cost-loaded models
5D BIM
Design change impact assessment
Automated quantity workflows
Model-to-BOQ workflows
Quantity reconciliation
Digital cost reporting
Data validation
Integration of structured asset information

Our principle:

The model is not the measurement. The model is the information source from which better measurement, analysis and decisions can be made.

05 Procurement & Tendering

Choosing how value enters the project.

Procurement strategy influences cost, risk, programme, competition and commercial control. We support clients in developing and implementing procurement strategies appropriate to the project’s objectives, market conditions and risk profile.

07 Post-Contract Cost Management

Turning the contract sum into commercial control.

Once construction begins, the role of the Quantity Surveyor evolves from establishing the cost baseline to protecting and forecasting the project’s financial outcome.

Our objective:

Know where the money has gone. Know where it is going. Know where the project will finish.

We provide post-contract cost management covering:

Cost control
Cost reporting
Forecast final cost
Cash-flow forecasting

Because Cost Intelligence Requires Context

We bring together Quantity Surveying, commercial management, contracts, claims, project controls, risk, digital engineering and strategic advisory capabilities. That multidisciplinary perspective allows us to look beyond the individual measurement, rate, variation or account and understand the wider commercial picture. We consider:

More Than Cost. Greater Value.

Our approach reflects the broader professional expectation of a quantity surveyor: not simply producing quantities and costs, but applying knowledge, analysis and professional judgement to provide reasoned advice to clients.

A QUANTITY SURVEYOR SHOULD NOT ONLY TELL YOU THE COST.

They should help you understand what the cost means in terms of VALUE.

At ANTERHILL, we believe that is where Quantity Surveying becomes commercial intelligence.

Whether you are developing a new asset, tendering a major project, managing construction costs, assessing a claim, recovering a project or closing a final account, we bring the measurement, analysis and commercial judgement required to make better-informed decisions.

Our leadership combines extensive experience across construction, infrastructure, engineering, commercial management, contracts, project delivery, dispute resolution, digital engineering and strategic advisory. We provide our people with the autonomy to apply their expertise, challenge conventional thinking and deliver meaningful outcomes for our clients.
