A REPORT ON DEMOUNTABLE PARKING STRUCTURES

THE DESIGN OF DEMOUNTABLE PARKING STRUCTURES APPEARS TO BE SHAPING UP INTO TWO DISTINCT PHILOSOPHIES: THE TINKERTOY AND BOX CONCEPTS. THE TINKERTOY CONCEPT IS BASED ON SMALL COMPONENTS EASILY HANDLED BY LIGHT EQUIPMENT IN THE FIELD. THE BOX SYSTEM ADVOCATES MAXIMUM OFF-SITE FABRICATION IN AS LARGE UNITS AS POSSIBLE. MANY VARIED USES FOR THE DEMOUNTABLE CONCEPT APPEAR: (1) INTERIM USE OF LAND, (2) LEASE LAND, (3) AIR SPACE, (4) TEMPORARY PARKING, AND (5) EXISTING HIGH-VOLUME PARKING LOTS. THE LOS ANGELES DEPARTMENT OF AIRPORTS (LAX) DEMOUNTABLE PARKING STRUCTURE PROJECT IS REPORTED. IT FOLLOWS THE BOX CONCEPT PRINCIPLES, LOW BIDDERS USING PRE-STRESSED CONCRETE. THE UNITS FOR THE SUCCESSFUL SYSTEM ARE FABRICATED AT THE PLANT AND TRANSPORTED ON TRAILERS TO THE BUILDING SITE. THE SYSTEM FURTHER EMPLOYS PREFABRICATED ELEVATOR SHAFTS AND STAIR SHAFTS WHICH ARE SIMPLY BOXES STACKED ATOP EACH OTHER AND WELDED. IN ADDITION TO DEPARTMENT OF AIRPORT REQUIREMENTS SPECIFYING BASIC MODULE AND LONG-SPAN, THE FOLLOWING ADDITIONAL CRITERIA WERE ESTABLISHED: (1) UTILIZE CONCRETE TO CAPITALIZE ON A MATERIAL THAT IS THE LOWEST COST STRUCTURAL MATERIAL AVAILABLE, (2) DEVELOP A CONCRETE SYSTEM CAPABLE OF BEING FIRE-RATED THOUGH NOT REQUIRED BY SPECIFICATIONS, (3) CAPITALIZE ON THE ECONOMICS TO BE GAINED USING LONG-SPAN, POST-TENSIONED REINFORCED DESIGN, (4) DESIGN PLANT-BUILT UNITS TO MAXIMUM SIZE AVOIDING FIELD LABOR WHEREVER POSSIBLE, AND (5) DELIVER LOW COST, LONG LIFE, LOW MAINTENANCE AND QUALITY CONSTRUCTION.
