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) Repair of Damage Fiber Optic Cable (See Appendix A for cost analysis backup) This activity consists of the following tasks. • Pavement Saw-cutting and Trench excavation for cable repair Additional saw-cutting(50 LF)and trench excavation(20 SY or approximately 2 CY)for placement of the new fiber optic vault and conduit at an accessible location. The Electrical subcontractor's bid for the initial saw-cutting was$6.00 per LF. The additional saw-cutting is performed at the same unit price. A review of the unit prices for street and roadway projects shows unit prices ranging from$3.00 to$6.00 per LF. Trench excavation 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, see unit bid prices shown below(see attached WSDOT pages for backup). 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 50 LF of saw-cutting and 2 CY of trench excavation,the cost of saw-cutting and trench excavation can be expected to range'from$190 to$900. • 2" Conduit and fittings One length of 2" PVC conduit(total of 120 LF)with appropriate fittings and backfill—2" conduit and fittings from WSDOT Unit Bid Analysis web site (Northwest Region) ranges from$10 to$39 per LF. The contractor's unit price for this item is$0.75 per LF. For the estimated total.quantity of 1.20 LF,the cost for 2" conduit can be expected to range from$1,200 to$4,680. • Fiber Optic Vault One Type 3030-LA bottomless utility vault(traffic rated)was installed at the location of the splice The . contractor's unit price for this item is$702.00 per each. Independent consultation with Oldcastle Precast provided a unit price of$702.00. For the quantity of 1 utility vault,the cost is$702. • Coordination Contractor coordinated with the Utility Locate service for repair of the severed fiber optic cable. The Coordination resulted in one additional round trip site visit by the Electrical Subcontractor to the project site from the project office in Ellensburg. Materials cost represents the estimated cost of fuel for this trips. Each round trip is approximately 215 miles. Using the current government allowable mileage allowance of$0.565 per mile,the cost per trip is$121. The labor estimate reflects 4 hours of travel time per round trip(total of 12 hours) plus 8 hours of coordination time with the Utility Locate crew while on= site. For coordination of 12 hours at the labor rate of$75 per hour(see below),the cost is$900. • 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 - Eq=uipment rates were established using the 2003/2004 NECA Tool and Equipment Schedule. On-site durations match field.observations. Equipment total charge of$2,260.40 is lower than the billing rates from the February 2013 NECA rates schedule. Based on these line items,the rounded cost to repair damage of the fiber optic line can be anticipated to range from approximately$5,400 to$8,900. Repair of Damaged Fiber Optic Cable change order price from ICON Materials $4,888.94 Conclusion: The requested change order amount is less than the estimated cost estimate range and is fair and reasonable.
