Vehicle Gateway Monitoring Systems Turn-Key Installation

Description of Tasks Performed in Turn-Key Installation of Vehicle Gateway Monitoring Systems

Several man-days of effort are required to perform all steps prior to Ludlum factory representative arrival for final wiring termination and training.

Turn-key installation by DEQ personnel include building 2 forms to be used for poured concrete. These forms are to allow concrete to set 6 inches above grade level of actual scale. Part of this process includes digging two trenches on either side of scale that are approximately 5 foot long, 3 foot wide, and 2 1/2 foot deep. Along with setting the bolts for the two detector stands and running conduit through the footer, an I-beam, channel, or other rigid post is to be set on both sides of both detector stands. This is provided for protection of the detector stands from oversized loads. See pictures below of a typical installation.

High strength, fast-setting concrete with fiberglass reinforcement is used for the footers. Nominally, 3 1/2 to 4 1/2 cubic yards of concrete are required.

Trenches, if required, are then dug from the far-side detector to the near-side detector. Conduit is installed in the trenches for power cables and signal cables. Also, trenches are dug for conduit going back to the scale office. Conduit is installed and wire pulled all the way back to the office. Conduit and wiring are then pulled through the office wall at the floor level or ceiling level to minimize visual impact. All trenches are then filled with either, dirt, asphalt patch, or concrete patch, depending on what material was trenched.

The computer and printer are mounted to the wall inside the scale office. See picture on right. Cabling is brought from the building entry point to the computer location. All cable runs meet national electrical codes.

Detectors and stands are lifted into place and bolted. Mounting of infrared sensors and wiring is done on the detector stands.

In the scale office a 15 amp separate breaker is added to the electrical panel.

For the price quoted, two items are required to be provided by the yard owners. In the scale office building, a separate 15-amp circuit needs to be provided. DEQ only needs an expansion slot at the electrical panel in the building.

DEQ also asks for a heavy lifting device and operator. The lifting device needs to be able to lift a minimum of 5000 pounds and a vertical lift of at least 12 feet above grade. We estimate needing this device and operator for a maximum of 1 to 1 1/2 hours.
