<br />Construction Cost Estimate <br /> <br /> <br /> <br /> <br /> <br /> <br />NOTES: <br />▪ $2/lb is a very low unit cost to <br />underscore the difference. <br />▪ Steel box girders require lighting <br />and ventilation for internal <br />inspection. FUBs do not. <br />▪ Steel boxes must be painted in <br />this environment which costs <br />approx. $500k. <br />▪ Painting requires lane closures <br />with traffic disruption. <br />From 2019 RFP Addendum #1 <br />▪ Total Budget: $13,050,000 <br />▪ Design Budget: $1,995,000 <br />▪ Construction Budget (Total Budget - Design Budget): $11M <br />Preliminary Construction Estimate: $7M << $11M <br />▪ Includes $600k contingency <br />Cost Comparison: <br />▪ FUBs = $360k <br />▪ Steel Box Girders = 150ft*1500lb/ft*$2/lb * 3 Girders = $1.3M <br />▪ Difference of over $1M in just main girders if steel used!
