RE:	November 15, 2011 Agenda Item – Award Bid for Unit 284/2005 TV Inspection Van and CCTV System Replacement

Please include the following item on the City Commission Agenda for consideration at the November 15, 2011 meeting:

Award Bid No. B1144 for the Utilities Department TV Inspection Van and CCTV System Replacement to Baker Equipment Company in the amount of $203,396.

Background:

One of the critical components of the Utilities Department sanitary sewer maintenance program involves using a closed circuit television system (CCTV) to inspect all sanitary sewer mains and service line connections every 10 years. This system consists of a self propelled color camera with a pan and tilt head which can turn 360 degrees in any direction transmitting a picture to a monitor, video recorder and computer located inside a van. Using this system, problems can be located and identified quickly so that proper corrective actions can be taken. A ranking system analyzes the defects found in individual sewer segments and systematically prioritizes pipe condition and defects. Along with finding sewer system deficiencies and prioritizing maintenance activities, the crew is also responsible for CCTV inspection of newly constructed sanitary sewers.

Current Status:

As of 07/27/2011, only 68,115 feet or 35% of the annual inspection workload is complete. The division is behind 46,218 feet or 23% in the program as well as not being able to complete follow-up inspections of blockages in city mains. The TV van was taken to the shop again on July 5, 2011 and was not operable the entire month of July. Central Maintenance has not calculated the cost of the current repair.

The Department purchased the current CCTV system and van in May 2005 for $148,500. The van chassis has 27,177 miles but the diesel engine in the van has 6,324 hours of operation which is equivalent to 252,960 miles. Through June 2011, the van chassis has been in the shop 328 hours for mechanical repairs at a total cost of $32,193. The van chassis is outfitted with an Aries CCTV system. The total CCTV system repair cost through July 2011 is $52,678. The total repair cost for the van chassis and CCTV system is $84,871 or more than 55% of the original purchase price.

The City of Lawrence Vehicle Replacement Model Guidelines submitted by Central Maintenance for Unit 284 has a rating of 43.30. As per the point range, Unit 284 is rated IV. This qualifies as a needs immediate consideration for replacement.

Pricing for a contractor to perform TV inspection work ranges from $3.50 per foot to $5.00 per foot. The cost depends on the amount of footage televised. In 2010, the division televised 182,116 feet of pipe. The cost for a contractor to complete this amount of work is between $637,406 and $910,580. This cost is for the use of one TV truck and one TV operator.

The Utilities Department cost to TV inspect the footage in 2010, was $234,180 or $1.29 per foot. This includes two employee’s salaries and benefits as well as the cost for the TV truck.

On September 27, 2011 the City Commission set a bid date of October 25, 2011. Five bids were submitted with the results in the table below.
