A Bottom-Up Approach to On-Time, On-Budget Projects

摘要

Cost overruns and delayed projects are increasingly unacceptable, as owners demand that estimates, budgets and schedules better align with construction reality. Effectively matching actuals to estimates, schedules and budgets is largely dependent on an appropriate level of detail-a challenge a decade ago. Today, modern systems have the intelligence to capture history and benchmark estimates, budgets and schedules to a granular level. For instance, concrete columns for a bridge deck require several steps, such as form setting, pouring concrete, stripping, etc. In a building or plant scenario, the granular breakdown might be at the component level-think pieces of structural steel, spools of pipe or conduit. Accurate estimates of time, work hours and cost to complete each "step" or component provide meaningful intelligence. There is much that can be learned and repeated on future projects at the component level with a bottom-up approach to project management.
