USING DREXEL INSTITUTE OF PHILADELPHIA AS A CASE STUDY, EDUCATIONAL FACILITIES LABORATORIES INVESTIGATED SIX AREAS OF INQUIRY FACING AN URBAN UNIVERSITY CONTEMPLATING EXPANSION--(1) THE ECONOMICS OF THE HIGH-RISE BUILDING, (2) THE ECONOMICS OF CONSTRUCTING LOW BUILDING UNITS WHICH CAN BE VERTICALLY EXPANDED AT A LATER DATE, (3) THE CONVERSION OF INDUSTRIAL BUILDINGS TO EDUCATIONAL USE, (4) THE PARKING PROBLEM, (5) ARRANGEMENT AND USE OF SPACE TO ACHIEVE HIGH UTILIZATION, AND (6) THE DETERMINATION OF FUTURE SPACE REQUIREMENTS. THE FINDINGS WERE--(1) THE RELATIONSHIP BETWEEN THE COST OF THE LAND AND THE COST OF VERTICAL TRANSPORTATION IS THE PRIMARY CONSIDERATION OF THE PRACTICALITY OF A HIGH RISE, $9.50 PER SQUARE FOOT BEING THE EQUIVALENT FIGURE, (2) CONSTRUCTING A LOW BUILDING TO PROVIDE FOR FUTURE VERTICAL EXPANSION IS PRACTICAL EXCEPT WHERE PROHIBITIVE SOIL CONDITIONS EXIST, (3) ECONOMICS OF TIME AND MONEY ARE ACHIEVED IN CONVERSION OF AN INDUSTRIAL BUILDING TO ACADEMIC USE IF THE LOCATION IS GOOD, (4) A MULTIPLE-STORY OPEN AIR PARKING GARAGE IS ECONOMICALLY FEASIBLE WHEN LAND IS MORE EXPENSIVE THAN $5 PER SQUARE FOOT, (5) COMPACTNESS IS THE KEY TO HIGH FACILITY UTILIZATION, AND (6) A MASTER PLAN IS NEEDED TO PREDICT FUTURE ENROLLMENT AND ITS ENSUING EFFECT UPON CLASSROOM, LABORATORY AND OFFICE SPACE. AN APPENDIX INCLUDES FORMS FOR GATHERING UTILIZATION AND PREDICTIVE DATA. THIS DOCUMENT IS AVAILABLE FROM EDUCATIONAL FACILITIES LABORATORIES, INC., 477 MADISON AVENUE, NEW YORK 22, NEW YORK. (JP)
