INTERWEST CONSTRUCTION INC. 3/26/2019 Change Order 10

• LF Pricing for L01 fixtures will be valid until the end of February. Interwest believes it will be possible to negotiate with the suppliers to hold pricing until early March but may have to solicit new pricing soon (included pricing was supplied by the vendor and forwarded to the City in September. Electric West has worked diligently to maintain this pricing since that time). • A significant portion of the cost for the LO1 fixture system is the design and submittal process as well as the controller/dimmer system. This cost is captured in the LS cost to supply 1,350 LF. The base design cost and system controls can reasonably extended to cover limited additional footage without additional cost. Supply of additional LOI System footage up to 200 LF can be accomplished without additional Prime Contractor overhead charges for the amount listed below. • If additional footage is required by the City and material costs increase between approval of this COP and fmal system footage decisions/placement of the material order, Interwest and Electric West reserve the right to revisit the unit price for additional footage beyond 1,350 LF to address any changes in material pricing. • Sales tax has been included on materials Interwest proposes the following Pricing for these changed conditions: • L01 Fixture Change for E1.01-E1.03&System Revisions $ 128,364.44 Lump Sum • L01 Additional Footage over 1,350LF&less than 1,550 LF $ 134.64 LF ESTIMATED TOTAL W/50 LF Additional Footage $ 135,096.44 Interwest requests 0 additional Contract Days work to perform this work. The City's response is requested by March 8th,2019 to facilitate procurement and planning associated with this work. Please do not hesitate to contact me if you wish to discuss this matter.
