CITY OF LA PORTE INTER-OFFICE MEMORANDUM T0: J FROM: J SU$JECT: Se ty DATE: December 29, 1983 ~' Purchasing Agent ett, Assistant Public Works Director: Bids - High Compaction Garbage Trucks° 4 The City of La Porte has received sealed bids for two (2) high'~ompaction, rear-loading residential garbage trucks. Bids were received from Basic Waste Systems, Inc., ,Environmental Sales and Service, inc.,=and Industrial Disposal Supply Company• • Apparent low bidder was from ~~sic Waste Systems, Inc. 'for two (2) Heil Formula 5;000's, for a total-price a,'~;$126,990,00. Review of manufacture's information, together with the bid submitted, reveal that this unit will not. meet the intent of City of La-Port e:, specifications. The ratio of pounds per cubic yard compacted is the basic. indication of a high- compaction body. The'Heil~Formula 5000 was tested by the City of La Porte in October, and averaged 8.5.0 pounds per cubic yard, S~ecificati©ns cal,l for 900 pounds per cubic yard:. The hydraulic system is the heart of a garbage truck. The Heil operates on a high .pressure, low volume hydraulic pump. The standard. pump for the Heil operates at 2~ gpm. The two competing trucks operate on low pressure, high volume, and standard pumps exceed 40 gpm. In order to meet specifications, Basic Waste Systems has proposed to install a ~+8 gpm pump, almost twice the volume of the standard. Because the Heil 5000 is designed for a 26 gpm pump at high pressure ,,.the. bigger pump will result in higher temperatures and increased downtime due to hydraulic leaks, The greater distance to the landfill in Baytown is the primary reason to buy the high-compaction. truck. The higher compaction will enable the Solid Waste Division to collect more garbage with fewer trips to the landfill. Because ac~~ual field tests revealed that the Heil will not compact. to minimum specifications, and' the proposed. increased pressure on a high pressure hydraulic system will result in excessive downtime, we recommend that the bid submitted by Basic Waste Systems, Inc., be disallowed. ~.
