B. Performance Requirement:
1. The BHS is to be constructed to serve the performance standards listed herein.
a. The BHS shall not have jams in excess of 1%. This is calculated by taking the
total number of bag jam events divided by the total number of bags in a 24 hour
period. Three (3) bags shall be counted in any given bag jam.
2. System Processing:
a. Collecting Conveyor: 1350 Bags Per Hour
b. Transport Conveyor: 1800 Bags Per Hour
C. Mechanical Design:
1. The BHSC shall be responsible for the detail design, fabrication, and installation of the
systems to satisfy the requirements herein.
2. The drawings depict substantial physical and dimensional constraints necessary for
coordination with the building structure, the existing mechanical and electrical equipment
within the limited building envelope. The design represents functional requirements of
the stakeholders. Minor alterations to the design to accommodate the BHSC’s equipment
shall be left to the discretion of the BHSC. Verify all given dimensions and to obtain all
other required dimensions from actual field measurements. The conveyor equipment
schedule on the drawings is only intended for reference. Detail system engineering shall
be the responsibility of the BHSC/manufacturer in accordance with good design practice
for airport Baggage Handling Systems (BHS).
3. All steel works are related to BHS shall be part of BHS scope of work under BHSC.
4. Baggage Characteristics:
a. The equipment for standard bags shall be capable of conveying baggage of various
sizes and shapes with dimensions not to exceed 26” high x 36” wide. Lengths of
baggage, in general, will not exceed 54”.
b. The minimum size of conveyable baggage is presumed to be 4” high by 12” wide
by 12” long. The conveyable baggage under 12” shall be conveyed in a tub.
c. The maximum weight per piece of baggage shall be assumed to be 100 lbs. The
live load is assumed to be 40 lbs. per lineal foot at 90 fpm loading belts. All
accumulating, load and unload conveyors shall be designed for a live load of 60
lbs. per lineal foot at 90 fpm. All conveyor equipment shall be capable of
supporting a single concentrated load of 250 lbs.
5. Clearances and Configuration:
a. Conveyor lines shall be engineered and installed to have a minimum of 28”
baggage clearance above the belt surface for standard bag.
b. Conveyors with the associated catwalks installed over the driveways shall provide
at least 8’-0” clearance to the lowest hanger of the catwalk, conveyor or drive
components, unless noted otherwise on drawings.
c. Maximum Angles:
