Comparative costs have been taken from bid prices for other projects,from construction cost guides and from quotes from suppliers. The quantities to complete each of the activities listed below are small in comparison to the quantities for a typical project,therefore unit prices for the items listed will be higher than expected for a large quantity. 1) Temporary Threshold Lighting for North Bridge Replacement This activity consists of the following tasks. • Excavation and Haul The excavation and hauling(exporting)of spoils is the equivalent of the WSDOT bid item Structure Excavation Class B Incl. Haul. From the Unit Bid Analysis WSDOT web site for this item and for small quantities, unit bid prices ranged from $1.00 to$500.00 per cubic yard (CY). Using engineering judgment, both of these values are outliers and the practical range for unit bid prices ranges from $21.50 to$300. For the estimated quantity of 10 CY,the cost for Excavation and Export can be expected to range from $200 to$3,000. • 12-Inch Can Extensions Provide and install 12-inch Base Can extensions for mounting of the temporary threshold lights. The contractor's unit price of$25 per unit is within the industry standard for this item of work. For the estimated total quantity of 12 each,the cost for the Base Can Extensions is$300. • SkV Cable and Splice Kits Provide and install approximately 450 LF of cable and 24 splice kits. The contractor's unit prices of$1.15 per LF of cable and $16.35 per each for splice kits are within the industry standard for this item of work. For the estimated quantity of 450 LF of cable and with splices,the cost is$909.90. • Threshold Lights Install 18 Airport provided threshold light fixtures. For the element of work,there is not cost for materials. • Threshold Lens " Provide and install 18 threshold lenses. The contractor's unit prices of$63.95 per each is within the industry standard for this item of work. For the quantity of 18 Each of threshold lenses,the cost is$1,151.10. • .Labor The labor effort matches the contractor's effort to accomplish this task. The labor rate of$75 closely matches the labor rate of$77.91 from the 2012 Friday Harbor Airport project. • Equipment Equipment rates were established using the 2003/2004 NECA Tool and Equipment Schedule. On-site durations match field observations. Equipment total charge of$346.47 is lower than the billing rates from the February 2013 NECA rates schedule. Temporary Threshold Lighting change order price from ICON Materials $10,715.67 Conclusion: The requested change order amount is a fair and reasonable estimate for completion of the Temporary Threshold Lighting system.
