The Australian Cost engineering Society (ACES) was formed in 1996 to provide opportunities for the exchange of information on the development of total cost management technologies in Australia and to encourage increased training and recognition for practitioners. The ACES is a technical society of Engineers Australia, and an affiliate to the Association for the Advancement of Cost Engineering International (AACEI). The ACES is also a member of the International Cost Engineering Council (ICEC). Our members have considerable experience in control of cost and time on all size projects but for some there is a particular focus on engineering construction projects of the $100 million plus range. The specialist project control skills applied on large and mega projects are also applied by our members to other types of projects such as building, maintenance, software and other highly technical projects. We have common cause with a number of other professional groups such as Quantity Surveyors, Project Management, and aspects of Chartered Accounting. However, we bring specialist hands-on skills for reliable control of complex and significant projects to deliver a defined scope within cost and time targets. Some of these project control skills are generally known as planning, scheduling, estimating, budgeting, financial analysis, forecasting, contract management and change control. We bring an integrated and targeted approach to control of projects.
