Maintainingtighter project cost control is at the top of every list of strategic goals for major engineeringand construction projects in the process industries. This criterion has a special influence on the world of instrumentation, where advancing technology continually adds to the complexity of devices, systems, and work processes. Most computer-aided estimating tools employ cumbersome spreadsheets which are difficultto use, maintain and update. They fall short of

I itating the estimating process.

A progressive solution to these problems has been developed and project-tested. This approach uses a self-documenting process and computer program which facilitate the production of either detailed or factored estimates. The computer-based system incorporatesstraightforward pull-down menus, input from picklistswhere appropriate, relational databases, and current data on pricing, installationmaterials and activity workhours. The system also features on-line context-sensitive help, inter-disciplinefile transfers, flexibility to define defaults and new categories, and concise reportsat multiple levels of detail. All documentation supporting an estimate is generated and stored both electronically and in hard-copyform for historical database update and permanent file retention.

Benefitsfrom this system include more timely, consistent and accurate original estimates, improved management of chan...
