Estimating Adaptation Costs: M-CACES
Description

M-CACES, a Windows-based software program, is required by the U.S. Army Corps of Engineers for the preparation of water resources construction and rehabilitation cost estimates for projects with federal costs exceeding US$2 million. The Unit Price Book associated with M-CACES provides production rates, unit costs, and crew composition for the United States. Price escalation for inflation is used to adjust pricing to the project schedule and to fully fund the estimate.

Appropriate Use Useful for estimating the costs of large natural resources construction projects (including dams, shoreline protection, and ecosystem rehabilitation). Best used for final rather than initial cost analyses due to the amount of time and data required to complete.
Scope Designed for the United States, but can be adapted to other countries; multiple sectors; site-specific.
Key Output Cost estimate for natural resources projects.
Key Input Quantity take-offs from drawings, specifications and references.
Ease of Use Requires extensive data on the costs associated with the project. Relatively easy to apply if data are available; more rigorous results require more analysis.
Training Required Training is suggested to acquire skill in developing quality cost estimates and customizing databases for site-specific or project-specific elements.
Training Available Building Systems Design (see Contacts) offers monthly training classes.
Computer Requirements IBM compatible computer with Windows 95 or later operating system.
Documentation Supplemental construction cost information is published in USA by R.S. Means Company, Inc., Publishers & Consultants, +1.617.585.7880, or Dodge Cost Systems, McGraw Hill Information Systems Company, +1.800.544.2678.
Applications

Used as an internal tool by the U.S. Army Corps of Engineers to estimate construction and rehabilitation costs of water resources projects. Also used by the U.S. Department of Defense, the U.S. Department of Energy, and the U.S. Environmental Protection Agency.
