CLIENT HAS PLASTIC PIPE EXTRUSION HEAD WEIGHING 63 KIPS ON A TROLLEY WHICH RIDES ON TRACKS 4'3" C-C AND CAN MOVE 16 FEET TO ONE SIDE AND BACK AGAIN, NOT MORE THAN ONCE DAILY. ALLOWABLE SOIL BEARING PRESSURE IS YET TO BE TESTED BUT EXPECTED TO BE 1600 PSF. IF A MAT 7 FEET WIDE × 18 FOOT LONG × 16" DEEP IS USED AS THE FOUNDATION, PRELIMINARY CALCULATIONS CONSIDERING A 16" DEEP × 24"WIDE SECTION OF THE MAT AS A BEAM UNDER EACH TRACK, MINIMAL REBAR STEEL IS REQUIRED FOR FLEXURE, BUT MAY NEED REINFORCEMENT FOR DIAGONAL SHEER, TOO. IF THE EQUIPMENT WAS STATIONARY, (PER CRSI) A 12" THICK 4 ½' SQUARE FOOTING WITH ONLY 5 # 5 BOTH WAYS IN BOTTOM WOULD CARRY A COLUMN LOAD OF 28 KIPS WITH NO DIAGONAL SHEER REBAR. ANY SUGGESTIONS?
