WHAT’S THE FUTURE?
PRE-FAB UNITS SAVE TIME BUT COST MORE …. SO
NEED TO SELECT RIGHT PROJECT FOR ITS USE
NEED COMPETITION
…. SO NEED TO ADVANCE DESIGN INSTEAD OF
DEPENDING ON FABRICATOR TO COMPLETE DESIGN
DESIGN SHOULD NOT CONSIDER “OVER” ECONOMIZE
THE SECTION DUE TO UPSIDE DOWN FABRICATION ….
MUST ALLOW FOR FUTURE DECK REPLACEMENT
WITHOUT OVERSTRESSING BEAMS
HIGH PRODUCTS (HIGH STEEL & HIGH CONCRETE) IS
EXPLORING CONCEPT OF “DOUBLE-T BEAMS”, WHICH
WILL APPLY CONCRETE PARKING GARAGE
TECHNOLOGY & TECHNIQUES AS A PRE-FAB
SUPERSTRUCTURE & DECK UNIT
