Institutional Considerations The BNSF Railroad Company will require that the project design be reviewed and accepted prior to construction. Permits, which may be required, are shown in the Institutional Considerations section Table VI-8 of Chapter VI. This project may be required to develop and conform to a City of Loveland Storm Water Management Plan during construction. Additionally the PUC will be contacted to determine if a PUC order to construct a bridge will be necessary. C. Comparative Evaluation The evaluation of alternatives were based on costs, technical merit, and preference of the Seven Lakes Reservoir Company and the BNSF Railroad Company since the above described evaluation factors are common to all alternatives considered for the project. A feasibility level probable cost estimate was developed for each of the alternatives. Major construction work items were identified and unit prices and quantities were estimated. The following assumptions were made: 1. Water level in the canal at the time of construction will not be inundating the existing culvert. This will be accomplished by controlling the flow north from Lake Loveland using cofferdams and temporary pumping as required. 2. The existing culvert is founded on suitable material and foundations for any new structures can be located at similar elevations. Additional measures may be required if bedrock is not suitable for the pile supports for the new bridge. 3. Mobilization/demobilization cost shown in the estimate is intended to cover the cost of mobilization and demobilization of equipment. temporary construction facilities, bonds and insurance. This cost item typically ranges from 5 to 15 percent of the total construction cost. The cost estimates were based on 10 percent. 24
