ESTIMATING


Phase retains world class estimators and professional Quantity Surveyors (PQS) experienced in delivering major capital cost estimates for some of the most prominent mine and mineral processing facilities of the last 45 years.
We can provide expert estimators and quantity surveyors available on an ad-hoc or full-time basis, engaged remotely or with an on-site presence.

First principles estimating of all classes of estimates in accordance with industry standards.
​
-
Material Take-off (Mto) And Bill of Quantity (Boq) Development by Skilled Qs’s
-
Conduct Independent Benchmarking and Modelling (e.g. Contingency, Escalation)
-
Conduct Third Party Estimate Review and Validation
-
Establish Estimating Standards and Tools for the Company or Customised to an Operating Asset
​
Phase personnel are currently integrated into owner’s teams on four continents, developing estimates and leading the project cost control functions for major mining projects in both the planning and implementation phases. This gives us cutting edge insights into market trends and access to the most current pricing for the key commodities and preponderant cost elements of Class 2 estimates.
Our involvement in project cost management from cradle to grave gives an advantage over pure estimating firms who rarely get to track their performance by monitoring the estimate baseline through to a final as-built cost report.
ALFRED SPATH
Chief Estimator
Alfred has 45 years of industry experience and is an industry per of the highest calibre. Alfred has prepared cost estimates for some of the industry’s largest copper milling/concentrator projects, including Newmont’s $3.1 billion Conga copper/gold plant, and AA’s $5.5 billion Quellaveco copper plant.
Alfred is experienced in estimating on major mining and mineral processing projects across all key commodities, and is highly skilled and accomplished estimator in their different phases and classes of estimates.

QUANTITY
MANAGEMENT
Quantity management is a crucial component estimating and transparency of the engineering design development is paramount.
We implement a robust approach to quantity measurement, monitoring and trending by establishing an integrated quantity tracking database that captures quantity development throughout the design and procurement process.
​
We also can develop construction package Bills of Quantities which support performance management and claims mitigation. This requires clear and comprehensive quantification of all the contract scope, measured in accordance with our Method of Measurement (MOM) and derived from evaluated engineer’s.
​
MTOs, Lists, 3D Models & Drawings, and Vendor Data
We create contract procedures designed to meet the requirements of progress measurement while ensuring fair payment for work performed. Our approach minimizes opportunistic claims by contractors and keeps projects on track.
​
Smart BOQs, Not Just Price Lists
Unlike traditional quantity surveying firms, we don’t just produce a typical BOQ. Instead, we develop a “smart” BOQ—a structured control tool that goes beyond pricing to help manage and monitor your project effectively.
​
Facilitating Progress & Risk Management
Our BOQs form the foundation for progress payment certificates (PPCs) and, in most cases, include labour hours. They are structured to support activity scheduling, progress monitoring, visual inspection, and de-risking of the measurement process—ensuring transparency and control at every stage.
