LED Street Lighting Conversion Project
Change Order 1
To approve Change Order No. 1 of the construction contract for the LED Street Lighting
Conversion project with Siemens Industry, Inc. of Austin, TX in an amount of $42,000.
Funding will be through Department 161 Street; Fund: Bond; Activity: LED Lighting.
Approximately 5,500 existing High Pressure Sodium (HPS) street lights are being
replaced with Light Emitting Diode (LED) street light through a contract with Siemens
Industry, Inc. Approximately, 239 specialty lights required replacement to finish the
contact. These lights are decorative, or special in nature, such as the two lights on the
historic Canal Street Bridge. Siemens estimated the contract price on an agreed to
allowance based on quotes for certain lighting fixtures. However, some of the chosen
replacement fixtures were more slightly more expensive than the allowance, requiring
additional funds.
In addition approximately 11 of the new LED lights have been damaged due to wind,
snow or ice weather events. While the City develops a maintenance program for
replacement fixtures, an additional number lights are included in this change order to
replace damaged lights.
The change order in amount of $42,000 will allow the City to purchase the remaining 239
specialty lights to replace the HPS lights with the LED lights and replaced the known
damaged lights.
