If this would be considered a "Public <br /> <br /> Work" by SOLI, prevailing wages would still need to be paid. <br /> <br /> Carol <br /> -----Original Message----- <br /> From: KLOPE Paul W <br /> Sent: Friday, March 25, 2005 8:27 AM <br /> To: POMES Carol K <br /> Subject: Request for exemption to use Sole source for RCC Pilot projects <br /> Engineering would like to contract with Eugene Sand and Gravel (ESG) as a Sole Source to construct a series of <br /> very small pavement rehab. projects in various locations to research various material characteristics, determine <br /> appropriate mix design parameters for locally available materials, and observe constructabilityand inplace <br /> performance using a variety of designs and construction techniques and observe it's durability under a variety of <br /> traffic loading environments of roller compacted concrete (RCC). This material has never been used in Eugene, <br /> and the only known location it has been used in the northwest for a public project is in Portland in the 1980's (the <br /> lead engineer for Portland's Transportation Bureau did not even know it existed and had no info. on it). I have <br /> been unable to locate other public installations of this material west of the Rockies. No other contractors or <br /> suppliers in the area have prepared or constructed RCC for public projects. My research has included a web <br /> search, discussions with City of Portland, Medford, Springfield, Bend, Salem, Corvallis, Lane County and ODOT, <br /> and discussions with national and regional concrete industry representatives. <br /> I have begun working with ESG providing them with information I have been able to gather regarding mix design <br /> and construction. Due to the experimental nature of this work, I need to be able to work with the same <br /> contractor/supplier over the course of all the installations so that they can learn how to make the mix correctly and <br /> install it correctly, and so that the City can determine what the best mix design, best construction techniques, and <br /> most successful design will be. This will allow us to write specifications and design methodology. <br /> Initially we have selected 4 locations to experiment with : a small section of bike path next to Jefferson Middle <br /> School; a small section of alley north of 13~' and east of High; several panels on the east side of Olive Street south <br /> of 18"'; and, depending on the results of the previous installations, a small section on the north of 18"' Street east <br /> of Chambers. The estimated total cost of all of these installations is $46,324 (without 18"', it is $29,391). <br /> Depending on what we learn on these installations, I would like to include an "option" for a future set of <br /> installations, if needed, of up to approximately the same dollar amount under this same Sole Source exemption. <br /> Please contact me if you need more information. <br /> 1 <br /> <br />
