📝 Scope Review Consideration
Compare the issued drawings with specifications and equipment schedules. Record conflicting requirements as requests for clarification and agree their treatment before pricing.
🔍 Scope Gap Warning
Instrument air and electrical coordination for control panels is a common gap. The control panel spec may require instrument air connections that fall under mechanical scope but terminate at equipment under electrical scope.
Local Cost Factors
Contractor Challenges in Ohio
Extreme competition for skilled electricians caused by the Intel mega-fab in Columbus and long equipment lead times for high-voltage switchgear.
Granular Division 26, 27, and 28 material takeoffs with customizable labor productivity units in Excel and highlighted Bluebeam drawings.
⚠ Bid-Day Risk Factor
Material price escalation clauses are becoming standard in longer-duration projects. We recommend including a 5-8% annual escalation factor for projects spanning more than 12 months.
