SECTION 1

1.0 SCOPE

This statement of work covers the necessary services, labor, material, equipment and control components required to repair and make operational the binnable receiving case conveyor and demolish and dispose and replace the existing bulk receiving pallet conveyor system in Bldg. 499, Zone 1 and replace, provide, install, test and make operational a new bulk receiving conveyor system in Bldg.

499, Zone 1.

1.1 SITE

The site of work is located at the DLA Distribution Depot Red River (DDRT), on the site of Red River Anny Depot. DDRT is located approximately 18 miles west of Texarkana, Texas on Interstate 30. The Contractor entrance to the depot is

0.3 miles south of exit 206 and 0.2 miles east on U.S. Hwy 82. The installation of the work is located in Bldg. 499, Zone 2. Bldg. 499 was built in 1995 and the building is 1000 ft. long by 640 ft. wide x 30 ft. clear stack height. The dimensions of zone 2 are 320 ft. wide x 380 ft. long.

1.2 SYSTEM LAYOUT AND FUNCTION

1.2.1 ORIGINAL BINNABLE RECEIVING CONVEYOR SYSTEM (REFER

TO DRAWING NO. 19-2-1)

. The function of the system is to receive and transport binnable material from the commercial truck receiving door in Bays A-E 24 of Bldg. 499 to the receiving inspection workstations for processing in Bays A-E 1-17 and then to storage in Bldg. 499 in zone 3 or 5. A large problem with the existing system is the inability to efficiently off-load commercial carriers, transport the material to the inspection stations, and then to storage. The existing system has been abandoned in place because the PLC is 25 years old, the totes which had a bar code on the side are no longer on-site and the panel view display has burnt out and is no longer commercial available. Also the raster scanning system at the workstations no longer functions because there is no bar code to read on the totepan. Under the original operating scenario, the extendaveyor system was used to off-load material in Bay A24 from floor loaded trucks. The material would be placed in totes with a barcode on the side that had the routing information for which type of receipt the material was and the inspection line destination. Material would travel from the extendaveyor to Bay A.5 17 where the raster scanner would read the barcode and if the material was for that line the material would divert to the inspection line. The material would then be inspected and then loaded onto the towline vehicle if the vehicle is to be stored in zones 3 or 5. If the material is an IFR (Issue from Receipt) the material would be placed on the middle take-away conveyor between each pair of inspection lines then the take-away conveyor would transport the material to the tilt tray sorter in zone 3. Material was also inducted via totepan at the in check stations at Bays A.5-B 21.5 - 23. The material would be placed in a tote with the bar code on the side of the tote and the raster scanners would read the bar code to activate the divert to the assigned inspection station in Bays A.5-E 17-19. The current operating scenario is that material is palletized at the receiving door if it is floor loaded, the transported to the receiving workstations by forklift.

1.2.2 BINNABLE RECEVING CONVEYOR SYSTEM FIX COVERED UNDER

THIS CONTRACT. (REFER TO DRAWING NO. 19-2-2)

The material will arrive in FedEx and UPS commercial carrier vans at Bay A 24.

The extendaveyor operator will place the material on the belt conveyor after a pre-printed bar code is placed in the material at the door which tells the system the inspection line destination in Bays A.5-E 17-18. The in-check stations are for material being received on pallets or triwalls from the overhead doors in Bays A.5

– E 24. The existing conveyors as shown in Bays A-B 21.5-23 in drawing no.

19-2-1 shall be demoed and replaced. The outer two conveyors will be gravity conveyor workstations for the in-check operators. The center conveyor will be the take away conveyor to load the material onto the main receiving belt conveyor which transporter the material to the inspection stations. At the in-check station the operator will place a preprinted bar code label on top of the material which will tell the overhead scanner in Bay A-18 the inspection line destination. The lines will be numbered 1-18 starting at the north most line being line number 1.

Lines 1-2 will be ESD (electronic static discharge) lines (parts are sensitive to static electricity). Lines 3-14 will be dedicated to returns. Lines 15-16 will be for new procurement and lines 17-18 will be for PPP&M. After the material is inspected and processed, the material will either be loaded on a towline cart for storage or on the middle takeaway line for IFRs between each pair of inspection lines for transportation to the tilt tray sorter in Zone 3 (200 series conveyor). The bar codes placed on the material at the in-check lines will be printed from the contractor provided printer from the software that is loaded on the contractor provided computer. This will be a stand-alone computer which is not tied to the DLA Network. The operator will pre-print a roll of the four type of barcodes so the bar code can be easily applied to the material at the in-check stations. Routing of material at the inspection lines shall be round robin going north to south for each of the four types of material. The controls system shall be upgraded to a Control Logix PLC System and the panel view system will be replaced. The line numbering of the different types of receipts will be programmed so that the lane assignment by receipt type can be easily changed by the operator. The chain diverts will be replace with powered ball or roller transfer for the powered take-away and the powered take-away line will be replace.

1.2.3 ORIGINAL BULK RECEIVING CONVEYOR SYSTEM. (REFER TO

DRAWING 19-2-1)

The Bulk Receiving Conveyor System/T-Car System is located in Bays B-E 18.5-

22. The existing system consists of twenty workstations, which consist of a combination of gravity roller conveyor at the load end (15 to 35 ft. long stepped for side forklift loading.) The gravity conveyors are for inspecting the pallets for receiving processing. The workstations are at the end of the gravity conveyor which transitions to 5 ft. of pallet conveyor follow by a turn table. The turntable is to have the ability to rotate the pallet if required. The turntable feeds the 10 ft.

long CDLR conveyor which feeds the T-Car. The operator hits the control at the turntable that releases the pallet to the CDLR and tells the T-car to either transport the material to the out-bound conveyor in Bay C.5-D.5 19 or the towline out-bound spur in the same bays.

1.2.4 NEW BULK RECEIVING CONVEYOR SYSTEM. (REFER TO

DRAWING 19-2-2)

The Bulk Receiving Conveyor System/T-Car System will still be located in Bays B.5-E 18.5-22. The new will system consists of nineteen workstations, which consist of powered accumulation pallet conveyor (APC) (15 to 35 ft. long stepped for side forklift loading.) The lines will be used from both returns and new procurement. The APC conveyors are for inspecting the pallets for receiving processing. The workstations will be at the end of the APC powered roller conveyor which transitions to 10 ft. sections of out-loading conveyor. The 5 ft.

CDLR conveyor and turntable will be eliminated. After the material is packed, the operator will hit a control which will release the material to feed the new 10 ft.

long APC conveyor which feeds the T-Car. The operator controls will tell the T-car to either transport the material to the out-bound conveyor in Bay C.5-D.5 21.5 or the towline out-bound spur in Bay C.5-D.5 18.
