Staff time to accompany Field Manager on building assessments - 1st site visit $ 120.00 Wilbur Koyukuk 8 hours over 2 days $15hr Conservative village office administrative percentage of total project cost less ABSN Admin %. Total project cost = $20,000/village - (our admin percentage , (around 12%) Approx: $2,400) = $17,600 x 5.5% = $968 (this 5.5% village admin cost estimate is spread across all entities we work with for the course of the grant for completing all energy efficiency measures. These are primarily for cumulative, otherwise unaccounted time expense for village- based project support. Feb, '07 through $ 968.00 Each time we call, email, or fax a village entity, someone has to receive the communication, review and/or foward the information, follow- up on requests, etc. Whether it is to set-up a teleconference, verify maintenance staff participation in lighting or boiler trainings, set-up in- kind lodging and transportation, lighting trainings, track a shipment, verify completion of lighting in a given building, ship lamps and ballasts out of the village, request a labor reimbursement agreement, or invoice etc. Village expenses for phone charges, copying and fax costs, office supplies, etc. are part of this amount. Lodging for ABSN Field Managers - 1st site visit 7/22-24/08 $75 Dan 3 nights stay at school ($25/night) Transportation and fuel costs - 1st site-visit 7/22-23/08 2 $ 25.00 $ 50.00 4-wheeler rental 1.5 days (Wilbur Koyukuk). Lodging for ABSN Field Managers - 2nd site visit 1/12-16/09 7 $50 $ 350.00 Lodging for Dan 4 nights & Anna 3 Nights TOTAL $1,703.00 The capacity of ABSN’s scope of work was increased by the response of local communities to work in partnership with ABSN and provide in-kind services of project coordination, paid labor for lighting retrofits, transportation and lodging for ABSN field staff, and other valuable contributions. This allowed ABSN and the community of Hughes to deliver 9% more energy savings measures beyond the original grant funding.
