History & Founding

From American Roots to Global Authority

AACE International was founded in 1956 when 59 cost estimators and cost engineers gathered at the University of New Hampshire in Durham, New Hampshire, to establish the American Association of Cost Engineers. These founding members recognised that cost engineering was emerging as a distinct professional discipline that required its own body of knowledge, standards, and professional community separate from general engineering or accounting.

Throughout the 1960s and 1970s, AACE grew steadily across the United States and began attracting international members, particularly from the process industries, construction, and mining sectors. The organisation began publishing Cost Engineering journal and developing the technical papers and standards that would form the foundation of modern cost engineering practice.

In 1990, recognising the increasingly global nature of its membership and influence, the organisation changed its name from the American Association of Cost Engineers to the Association for the Advancement of Cost Engineering. The legal name became AACE International in 1992, reflecting the organisation's worldwide scope and its commitment to advancing the profession on every continent.

Today, AACE International is headquartered in Morgantown, West Virginia, and serves as the pre-eminent global authority on cost engineering, total cost management, and project controls. With nearly seven decades of continuous operation, AACE has shaped how projects are estimated, budgeted, scheduled, and controlled across every major industry sector.

Mission & Scope

Advancing the Discipline of Total Cost Management

AACE International's mission is to provide its members and stakeholders with the resources they need to enhance and prove their value to the organisations they serve. The organisation achieves this through four pillars of activity:

Technical Research & Standards

Developing and maintaining peer-reviewed Recommended Practices, Professional Practice Guides, and the Total Cost Management Framework that define best practice across every discipline of cost engineering.

Professional Certification

Administering eight globally recognised certification programs that validate professional competency across cost estimating, scheduling, project controls, risk management, earned value management, and forensic claims.

Education & Professional Development

Providing continuing education through conferences, seminars, webinars, and online learning. The annual AACE International Conference and Expo is the premier gathering for cost engineering professionals worldwide.

Global Networking & Advocacy

Connecting cost engineering professionals through a global network of local sections, online communities, and professional events. AACE advocates for the recognition and advancement of cost engineering as a distinct professional discipline.

Global Membership

A Worldwide Community of Cost Professionals

AACE International has grown from its 59 founding members to a global community of over 10,000 members and certificants spanning more than 100 countries. The organisation's decentralised structure includes over 80 local sections organised geographically into 10 regions covering North America, Europe, Asia-Pacific, the Middle East, Africa, and Latin America.

AACE members work across a remarkably broad range of industries and sectors. While the organisation's roots lie in the process industries (petroleum refining, chemical processing, and power generation), AACE's reach now extends to construction, mining and resources, transport infrastructure, defence, aerospace, information technology, and government. This cross-sector perspective is one of AACE's greatest strengths, enabling the transfer of best practices between industries.

AACE Australian Section

The AACE Australian Section has a long history, originating as the AACE Melbourne Section in 1977 before expanding nationally during the 1980s. The Australian Section connects professionals in Sydney, Melbourne, Brisbane, and Perth with AACE International's global community, offering certification preparation courses, technical events, networking opportunities, and professional development resources tailored to the Australian context.

In 2018, a constitutional requirement led to the full organisational separation of the Australian Section from its previous affiliation with Engineers Australia, establishing independent elections, management, and financial governance. The Australian Section actively promotes AACE standards and certifications across Australia's mining, energy, infrastructure, and construction sectors, and regularly hosts the Project Controls Expo and other industry events.

For Australian cost engineering professionals, AACE membership provides access to an international body of knowledge that complements local standards like PCEM, while AACE certifications such as the CCP and CEP are widely recognised by employers across the Australian resources and infrastructure sectors.

Disciplines

The Practice Areas of Cost Engineering

AACE International defines cost engineering broadly as the application of scientific principles and techniques to problems of cost estimation, cost control, business planning, management science, and profitability analysis. Within this broad definition, AACE's work spans several interconnected disciplines:

Cost Estimating: Developing predictive cost models using parametric, analogous, and detailed bottom-up methodologies across all project phases and industry sectors
Planning & Scheduling: Developing and maintaining project schedules using Critical Path Method (CPM), resource loading, and schedule risk analysis techniques
Cost & Schedule Control: Monitoring and controlling project performance against baselines, managing change, and forecasting final costs and completion dates
Risk Management: Identifying, assessing, and quantifying project risks using probabilistic methods including Monte Carlo simulation for cost and schedule contingency determination
Earned Value Management (EVM): Integrating cost, schedule, and scope measurement to provide objective performance assessment and predictive analytics for project outcomes
Forensic Claims & Dispute Resolution: Analysing construction claims, delay analysis, disruption quantification, and providing expert testimony on cost and schedule disputes
Decision & Risk Analysis: Applying decision analysis frameworks, economic evaluation, and investment appraisal techniques to support strategic project and portfolio decisions
Publications & Standards

The AACE Body of Knowledge

AACE International maintains one of the most comprehensive bodies of knowledge in the cost engineering field. Its publications define the technical standards and methodologies used by practitioners worldwide.

Total Cost Management Framework (2nd Edition)

AACE's flagship publication and most comprehensive work. The TCM Framework is a structured, annotated process map that describes each practice area of cost engineering and how they interrelate. It provides the conceptual foundation upon which all AACE Recommended Practices and standards are built, covering strategic asset management, project controls, cost estimating, scheduling, risk management, and more.

Recommended Practices (120+)

Peer-reviewed technical documents that define specific methods, procedures, and standards for cost engineering activities. Key RPs include 18R-97 (Cost Estimate Classification System), 10S-90 (Cost Engineering Terminology), 17R-97 (Cost Estimate Classification for Construction), and 56R-08 (Cost Estimate Classification for Mining). Each RP undergoes rigorous technical review before publication.

Professional Practice Guides (20+)

Structured compilations of selected AACE publications on specific areas of cost engineering practice. These guides provide practitioners with consolidated reference material on topics such as project cost control, schedule development, and risk analysis.

Cost Engineering Journal

AACE's bi-monthly technical journal featuring peer-reviewed papers on cost engineering topics, industry research, case studies, and technical developments. The journal has been in continuous publication for over six decades and remains a primary vehicle for advancing cost engineering knowledge.

Skills and Knowledge of Cost Engineering (6th Edition)

The foundational reference text for cost engineering practitioners and certification candidates. This comprehensive volume covers the core competencies required across all AACE disciplines and serves as the primary study resource for AACE certification examinations.

Professional Landscape

How AACE Relates to Other Professional Bodies

AACE International operates alongside several other professional bodies that serve overlapping but distinct communities. Understanding these relationships helps practitioners determine which qualifications and memberships best suit their career path and project requirements.

Project Management Institute (PMI)

PMI focuses broadly on project management practice, while AACE specialises in the cost and schedule control disciplines within project management. The two bodies complement each other - many professionals hold both PMP and CCP certifications. AACE's technical depth in cost engineering and estimating goes beyond PMI's more general project management scope.

Royal Institution of Chartered Surveyors (RICS)

RICS represents quantity surveyors and cost managers primarily in the building and construction sectors, with strong presence in the UK, Australia, and Commonwealth countries. AACE covers a broader range of industries including process, mining, and energy. In Australia, both RICS and AACE credentials are valued, with RICS more common in building construction and AACE more prevalent in resources and heavy infrastructure.

Engineers Australia (EA)

Engineers Australia is the national professional body for engineers in Australia. While EA covers all engineering disciplines broadly, AACE provides specialist depth in cost engineering and project controls. The AACE Australian Section was historically affiliated with Engineers Australia before becoming fully independent in 2018. Many Australian cost engineers maintain membership in both organisations.

International Cost Engineering Council (ICEC)

ICEC is a confederation of national cost engineering societies from over 40 countries, of which AACE International is a founding member. ICEC promotes international cooperation between cost engineering bodies and facilitates the mutual recognition of professional qualifications across borders.
