INC. 139 E. 51st Avenue Anchorage, AK 99503 Reference: Bethel-NYAC Intertie D&L Cost Estimate Attached is our cost estimate for the Bethel-NYAC transmission line. It is based on the FPE Roen report of August 31, 1995 and Draft of April 1, 1996. We did change some items of their cost estimate that, in our opinion, were not workable. For example, the practical span for #2 ACSR on 50-foot poles is about 300 feet not 650 feet. This is also a logical span based on data from the FPE research of other rural utilities. We did not change the pole selection, wire (except for the river crossings) or permitting estimates and used the FPE suggestions wherever possible. We did not perform an engineering review of these docu- ments. We have included a fiber optic cable for future communication; this is fairly inex- pensive as part of the original construction and seems reasonable. In essence, this estimate is independent from the FPE estimate. We have used in-house labor data and acquired recent costs for other components such as: material, barge charges, sub- station components and equipment rental rates to arrive at our estimate. Our cursory design criteria for this estimate consists of the following main items: @ 50-foot, class 2, wood poles (FPE Roen) @ 3-phase, 3-wire Delta system @ 350-foot spans @ #2 ACSR (Sparrow) conductor ¢@ 24-inch pipe pile foundation @ Grade B NESC Construction @ 1993 NESC Heavy Loading Transmission, Distribution, Substations, System Planning LCMF Inc. June 10, 1996 Mr. Wiley Wilhelm Page 2 @ 60 mph with 1/2-inch ice special loading (FPE Roen) @ 1993 NESC Extreme wind load 100-mph @ 23-foot ground clearance (FPE Roen) @ ADSS Fiber Optic Cable @ .5 small angles per line mile @ .5 large angles per line mile @ .25 deadends per line mile @ River crossings High strength ACSR (Shoebill) conductor 1,200-foot span Loading criteria same as above 32.5-foot ground clearance (FPE Roen) 75/1 poles The construction cost estimate is based on the following assumptions of work conditions and procedures: + Due to the nature of the surrounding wetlands and environment, the construc- tion of the line is proposed for wintertime construction. The work is assumed to be performed by IBEW electrical contractors. The 1996 labor rates are used for the estimate. A work schedule of three weeks on and one week off, working twelve hour shifts, seven days per week is used to calculate work efficiency, overtime, and transportation costs. A pay rate of 40 hours straight time and 44 hours time- and-one-half per week is used. It is assumed that there will be four months when the line route will be readily accessible for construction equipment. Because of the limited construction window, the line construction is broken up into sections. The line from Bethel to Tuluksak is broken into three sections and the line from NYAC Junction to NYAC is broken into two sections. Each different section is assumed to be constructed by a separate work force. The estimate includes different camps and equipment for each different work force. LCMF Inc. June 10, 1996 Mr. Wiley Wilhelm Page 3 + A job superintendent is assumed to work full-time for four months prior to barge sailing, gathering all material and equipment in addition to eight months of construction and close-out time. An assistant is assumed to work half-time for the same period. This would result in 18-man months of non-productive foreman time which is added to the construction cost estimate for each work force. + The construction materials and equipment for all three sections from Bethel to Tuluksak could be barged up the Kuskokwim River on a single barge, prior to freeze-up. This barge would leave Anchorage the first of September. Mat- erial and equipment could then be staged along the way at Bethel, Akiachak, and Tuluksak. The construction camps could be ready by late September. It is also assumed that this equipment will remain on site until the following summer to be barged out, this is reflected in the equipment rental prices. A similar approach is taken for the NYAC Junction to NYAC line. + The surveying for the piling, poles, and anchors will be performed by a five- man crew using snowmachines/Nodwells in November. It is assumed that a minimal surveying crew remains for an additional month to aid during founda- tion installation and for incidental survey work. + The proposed pole foundations are to be 24-inch diameter, 20-foot long driven steel pipe piles using vibratory type hammers. Another option, which is not estimated, would auger holes and slurry direct embedded poles. ¢ Framing of the poles will take place in the field. + Existing substation modification and new substation construction will take place during the summer months. + Costs associated with obtaining permits and construction rights-of-way are taken from FPE Roen’s original estimate. + The conductor used for river crossings is a #2 AWG ACSR 3/4, “Shoebill.” This high strength conductor has a much reduced sag characteristic so river crossings can be accomplished without expensive river crossing structures. + A smaller span length than FPE’s estimate is required to maintain ground clearance. An average span length of 350 feet is used. + A fiber optic communication cable is also included in the estimate. Because of the changing technology and the future benefit to the surrounding communi- ties, it is a benefit that far exceeds its cost. LCMF Inc. June 10, 1996 Mr. Wiley Wilhelm Page 4 We initially thought an ice road would be the best method for line construction, but a review of climatological conditions and the cost of road making eliminated this option. Instead, we have made very brief inquiries into the local permitting area and now believe it will be possi- ble to construct the line using tracked vehicles on the frozen tundra. This method has the disadvantage of not leaving a maintenance road. The attached spreadsheets show the pieces and method of arriving at the final line construc- tion costs. Although other methods were investigated, these spreadsheets show most of the final pertinent information used along with a brief description. We have broken down the work into different construction units labor and material costs to reduce the effects of any one item on the overall estimate. The material costs have been directly quoted from local electrical equipment suppliers and savings associated with large volume purchases are in- cluded in the estimate. A Labor Cost spreadsheet shows how the labor rate was determined for this project. A typical crew breakdown and associated 1996 labor rates are used along with mandated pay- ments to IBEW, taxes, insurance, etc. to obtain labor burden. The attached equipment data sheets use prevailing Alaska rental rates and equipment operat- ing costs. These sheets show that the estimate takes into account both equipment rental time, operating costs and idle equipment rental time.
