Connective Corridor –Green Balance Sheet B&L Cost ITEM Rationale for requested adjustment Actual Bid (5/12/2011) Estimate ITEMS ADDED DUE TO GREEN INFRASTRUCTURE Storage Stone $298,500 $30/CY (Creekwalk bid) ‐ Assume $35 for a 17% contingency $ 200,970 Additional Trees/Shrubs Additional Trees/Shrubs $101 840 Bioretention removed from projects, deduct shrub costs from green. p j , $101,840 Split tree costs of $46,000 between City and County g $ 61,471 $ 61 471 Additional CU Soil $19,000 No Change $ 23,000 Trench Drains $8,610 Trench Drains assumed to be necessary for bike path drainage $ 8,200 6", 10", 24" & 36" Storage/Overflow Pipes (w/ deduction for underdrains) $170,795 No Change $ 74,710 Additional Drainage Structures/Frame & Grates Addi i lD i S /F &G $78,750 $78 750 Reduce to reflect the the smaller inlets for GI $ 117,222 $ 117 222 Adequate root volume for trees was a comment from City on original Silva Cell $97,458 design prior to Silva Cell pilot. Green share of silva cells assumed at 75% $ 106,310 and share of tree costs assumed to be 50%. ITEMS MODIFIED AS A RESULT OF GREEN INFRASTRUCTURE 8" Asphalt to 8" Porous Concrete (Parking Lane) $63,350 Unit Cost difference too high. Replace with $10/sq. ft. g p q $ 21,240 Green infrastructure does not require grass areas to be converted to porous pavers. Therefore, a 50% cost share ($116,250) would appear Regular Pavers/Top Soil & Seed to Porous Pavers $172,350 more reasonable $ 95,046 Please clarify the assumption for 39% of total traffic control being Work Zone Traffic Control $56,629 allocated to green.
