IFB 27DPW122C 15

3.03 Weighbridge Design and Construction

The platform shall be 34 feet long and 10 feet wide and shall consist of a nominal 6-inch factory-poured and cured concrete deck reinforced by 8-inch structural steel wide-flange beam stringers running the full length of the module.

Side beams shall be 12-inch structural steel members with Nelson studs attached to the internal sides of each beam to create a composite connection between the concrete and steel.

The scale shall be an open-bottom design. Corrugated sheeting shall not be entombed within the modules.

Understructure components consisting of formed U's, bent plates, or a bottom pan shall not be used.

Steel deck scales and poured-in-place concrete deck scales will not be considered.

The scale shall be constructed to be installed in the existing 34-foot by 10-foot foundation as constructed.

No structural modifications to the existing foundation shall be required to accept the new scale unless specifically identified in the contract documents.

The truck scale deck shall be factory poured and steam cured and shall be delivered to the site ready for installation. The factory-poured deck shall have an ultimate compressive strength of 8,000 psi.

The weighbridge deck concrete system shall contain silica fume at a rate of at least 10 percent of the cementitious material and shall contain steel fiber reinforcement for tensile strength and impact protection.

A poured-in-place design will not be accepted. A weighbridge poured in place on-site and subsequently transported into the existing foundation will also not be permitted.

3.04 Galvanizing

The structural steel weighbridge, stringers, base plates, checking assembly, retrofit bumper plates, associated hardware, bumper bolts, and clamp plates shall be hot-dip galvanized steel.

The manufacturer shall provide cold galvanizing touch-up paint with delivery of the scale.

3.05 Manways

The scale deck shall incorporate two manways providing technician access to the interior of the pit.

Manways shall be located at the 20-foot end of each end module.

Each manway shall measure 24 inches by 24 inches and shall incorporate a 1/4-inch galvanized steel deck plate for egress into the existing pit foundation.

3.06 Checking System

The scale shall utilize longitudinal and lateral bumper checking and shall be completely self-checking.

Check rods and flexure checking plates shall not be used. Checking components shall be mechanically isolated from the load cells and load cell stands/base plates.

3.07 Load Cells, Controllers, and Diagnostics

The scale shall utilize rocker-column load cells. Each rocker-column load cell shall have a minimum gross rated capacity of 66,000 pounds.

IFB 27DPW122C 16

Load cells shall be constructed of stainless steel, completely hermetically sealed against moisture intrusion, and nitrogen filled to retard internal corrosion.

The load cells shall meet or exceed the following minimum specifications:

Minimum capacity: 66,000 lbs.

Design: Rocker column Rated output: 2 ± 0.1% mV/V NTEP accuracy class: IIIL, 10,000 divisions Combined error: ≤ ±0.0200% RO Temperature effect on sensitivity: ≤ ±0.0166%/°C Excitation voltage: 5 to 15 volts Zero balance: ≤ ±5.0% RO Insulation resistance: ≥5,000 megohms Compensated temperature range: -10°C to +40°C Operating temperature range: -40°C to +80°C Safe load limit: 200% of capacity Ultimate load: 300% of capacity Load cell material: Stainless steel Sealing: Hermetically sealed; cable entry sealed by glass-to-metal header Protection: NEMA 6P/IP69K

Each load cell shall be provided with shielded four-conductor cable with a polyurethane jacket. Load cell cabling shall be protected by stainless steel braided armor to protect against abrasion and rodent damage.

Load cell cables shall be hardwired to the load cells. Quick-disconnect load cell cable connectors on load cells or junction boxes shall not be acceptable.

Load cells shall have a 25-year warranty, including damage resulting from surge or lightning while the scale is being serviced by an authorized manufacturer's agent.

Load cell output shall be a DC analog signal. Digital-output load cells shall not be acceptable.

Each load cell shall be optically isolated through a smart sectional controller. PC boards shall be encapsulated in epoxy or similar material and housed in a Type 304 stainless steel enclosure rated NEMA 4X.

Access to the encapsulated board within the smart sectional controller enclosure shall be possible without the use of tools. Bolts, screws, or other hardware shall not be required to seal the smart sectional controller enclosure.

The scale shall have self-diagnostic capabilities capable of identifying load cell problems and failures and predicting potential failures to minimize downtime. Diagnostics shall measure load cell counts, not weight, and shall be used to determine reliability.

In the event of a load cell failure, the instrumentation shall identify the specific failed load cell. All troubleshooting shall be capable of being performed from within the scale house.

The new scale shall integrate with and utilize the existing instrumentation and printer.
