I have made a fast indication on that listing as to where I understand the assigned pricing.is to be carried out. Example -tunnels and plugs -the escalation pr~c~ng ~nd quantities will be done in Buffalo -lining and plugs -will be quantified and priced in Niagara Falls. This list is being provided for discussion, so that we can break down the assignment packaging in the very near future. I would like to take certain quantifying and pricing packages and assign them to people in this office -andt-with your agreement, have you do the same with those ite:ns associated with the total Devil Canyon estimate.

In our estimate we included all the elements except the last two which will be looked after by the project. Background -Transmission Estimates During Acres trip to Alaska in 1980, we met with our sub- contractor R. W. Retherford Associates and discussed various facets of transmission line design and construction in Alaska. Rw~ had developed a special type of tower, X-type which was sui table for installa.tion in permafrost. This x-tower design was hinged at the foundations and guyed for ... stability. Further developments saw a move from alumin~u lattice design to tubular steel tower members. This lowered the cost of the labor component. RWPA provided Acres with the details of their estimates for a 230 kV, tubular steel tower line between Point Mackenzie and Fairbanks. This was based on 230 kV line (aluminum lattice) constructed in 1975 and 115 kV line (tubular steel) constructed in 1978. The RWRA estimate was. in 1978 dollars. Acres ve=y first estimates were based on a tubular steel, X-type tower. This has been justified by the decision of Commonwealth Associates recommending this type of tower and the eventual acceptance by APA. The Acres first estimates used the RWRA data and were developed for various voltage levels for the electric system studies. Telephone consultation with CAI confirmed Acres line costs. The present cost:s which are in the attached back-up material are based on CAI "Route Selection Report" dated October 1981. The estimate is in September, 1981 dollars. 11 . 11 J I·~ ·' I! I! 'I I, ' I ; .[~( ' 2 The following table sectionalizes the transmission lines with number of circuits and cost per mile. A total is generated for each section. The total cost is then divided by the estimated total length. This will give an average cost per mile. This cost will be used to stage the estimates, .e.g. Watana ·1993 and Devil Canyon 2002.. The di£ferences. in costs per mile are accounted for by the terrain, difficulty of access, type of fo.unda.tions required, etc.. Some areas will require winter construction or heli- copter assistance. section Watana- Devil Canyon Devil Canyon Gold Creek Gold Creek - Willow Wil10'\v - Xnik Ar.rn Knik Arm - University (one tower) Gold Creek - Healy Healy - Ester Total No. of Circuits 2 5 3 3 2 2 2 Length !vliles 52 65 213 120 36 200 164 850 Cost per Mile ($) 340,000 340,000 331,394 285,000 251,111 318,990 310,000 Total ($) 17,680,000 22,100,000 70,587,000 34,200,000 63,798,000 50,840,000 268,245,000 September, 1981 average cost of transmission per mile including intertie-268,245,000-$315,582. 850 The FERC format requires splitting the estimate into steel towers and fixtures and overhead conductors and devices. ll 11 \ 11 ~ ll 11 If 1·: , I I '.

The avera~e cost per mile developed above does not include costs for mobilization/demobilization or surveying. We also have to bring the costs up to January 1982 figures. For 1993 constr.uction 600 mi x $315,582 mobilization/ demobilization 5% surveying January 1982 costs x 1.04 deduct clearing $189,349,200 9,467,460 3,500,000 $202,316,660 210,409,326 10,409,326 $200,349,326 cost per mi -200,349,326 = $333,916 600 The tower costs according ~o FERC should include towers, foundations, hardware and insulators. Tower costs account for approximately 70 percent of line costs which are in turn split into approximately 57 percent for material and 43 percent for labor. We are a~surning that towers will be spaced at 1,200 ft and will require 4.4 tow~rs per mile. The total towers for 600 mi would be 600 x 4.4 -2,640.

Substation/Switchyard Estimates . Substations/switchyards costs based on the number of· elements contained and the space required to accommodate voltage . levels. The costs for this estima·te were based on the following -station base costs -circuit breaker positions -transformer positions8 . The costs were contained in the pi.·eliminary electric system report. These costs were upgraded to January 1982 figures and an additional factor to equalize them with the higher line costs. J I'· ~ I f I ,!

Sarofim .A. .:tex/D. Kausha1 I am attaching a report on transmission line costs which gives a history of the development .of transmission costs and shows how~hey were arr~ved at. The transmission line costs were est5~ated on a per mile basis and then broken down to suit the FERC format. We also used the CAI estimates for different terrain. This is summarized on page 2 of the report. The CAI estimates are close to ones we have devel- oped. See telephone conversation to D. Meilhede dated November 10, 1981 which explains main differences. At that time John Lawrence requested that our line estimates be adjusted to include the differences applicable to our lines. I tried in the report to give you a breakdown of the sub- station costs for each one and explained the main elements used. ' I am also including revised copies of the estL~ates.

The total percentage would theu amount to 35%. The cost estimate for switchyards at the powerhouses, e.g~ Watana and Devil Canyon have not been included. The cost estimate for the In-Plant Control System at Watana has been included. Also note that the Energy Management Syste.ui Center (System Control Center} is now included in the estimate. The material and labor costs were identified as requested. You will also note that the estimates have been staged for transmission lines and substations, e.g. 1993 and 2000+. The cost estimates have been identified by item numbers in accordance with FERC requirements. I believe the contingency etc should be applied to each item number rather than at the end of the total estimate. .· ENS:jlh. Attachment ' I l ! I I l I !
