This document discusses the importance of upfront planning when undertaking a building or renovation project. It states that the #1 costly mistake people make is not completing the project on time and on budget due to a lack of planning. It recommends completing a Needs and Options Review as the most important first step. This review establishes the project needs and all viable design options, ensuring legal requirements are met and the budget is sufficient before proceeding to later stages like drawings, bidding, and construction where changes are much more expensive. By taking the time for thorough upfront planning through a Needs and Options Review, a successful project can be built on a solid foundation.
