HEAVY MATERIALS WAREHOUSE
Section 5:
Definition. Heavy materials warehouses are facilities designed for
5.1
the storage and handling of loads which exceed the average size and weight of
Navy standard pallets. Such facilities are usually associated with
manufacturing/fabrication or steel storage. Overhead handling devices such as
bridge cranes are important elements in the design of these facilities. Refer
to NAVFAC P-272, drawing 1404213, for a typical configuration. Section 5
provides additional specific criteria applicable to heavy materials storage.
Observe the following requirements:
Construction.
5.2
Doors/Windows. Provide windows for office and service structures.
5.2.1
A narrow row of windows shall be considered along the top of exterior walls to
supplement electric illumination.
Floors. Design concrete floors for the expected load conditions.
5.2.2
Minimum floor thickness shall be 6 inches (150 mm). Provide reinforcement for
crack control or incorporate alternative methods of crack control. Increased
floor thickness may be required for areas subject to heavy loading. Special
toppings or hardening compounds may be specified for areas subjected to
extreme loading, traffic conditions, or requiring the use of air film
transporters.
Craneways. Design craneways for the intended load capacity and type
5.2.3
equipment to be used. Craneway location shall avoid interference with the
building structure or areas of personnel activity. Provide clearance between
adjacent cranes and between the crane and the building structure.
Site Planning. The location of a heavy materials warehouse will be
5.3
determined by the source of materials, the destination of materials,
associated shop operations, and internal shop operations required to rough
size material before being sent to its destination. Consider the following:
Rail Access. Building location will be affected by the ability to
5.3.1
provide rail access from nearby tracks. The possibility of running a track
through the building shall be considered. Inside tracks shall be at floor
level and be equipped with crossing plates to provide a continuous, smooth
crossing over the entire length of the track. A rail pit, placing the car
floor at the building floor level, is not recommended since such a pit will
divide the warehouse and prevent efficient use of the facility.
Truck Access. Provide truck dock and apron space for truck access
5.3.2
to the building. A combination of floor level drive-in doors and docks with
dock levelers shall be provided to handle any combination of vehicles.
Drive-in doors should accommodate flatbed and semi-trailers and be located to
permit overhead crane loading and unloading.
Expansion. Provide for expansion in proportion to the requirements
5.3.3
expected of the associated operations to be supported by the heavy materials
warehouse. Provisions shall be made for the expansion of the building width
and length to accommodate growth.
