AC 150/5300-4B <br />6/24/75 <br />c. Arrange the building components to provide: <br />(1) Short and direct pedestrian routes from parking areas to public <br />waiting areas or airport offices, and to the loading apron or <br />tiedown areas. <br />(2) A view of the airfield operations from the manager's office, <br />the waiting room, and the eating facilities, if any. <br />50. EXPANSION. <br />a. Future expansion of the administration building must be planned <br />from the start. This is very important at the general aviation <br />airport where, because it is difficult to make accurate forecasts, <br />initial construction has to be based on actual measurable activity. <br />b. When the field side of the building is fixed, as it usually is, <br />there can be expansion only on the off -field side and the two ends. <br />When drives and walks resist expansion on the off -field side, plan <br />all major expansion at the building ends. <br />51. CIRCULATION. The waiting room is the hub from which circulation routes <br />radiate. Usually, an open plan with only the most essential parti- <br />tioning allows better circulation as well as a more spacious building <br />interior. Consider the following important items to assure satis- <br />factory circulation of traffic through the building: <br />a. Short and direct routes from the entrance of the off -field side <br />of the building to the exit on the field side. <br />b. Wide doorways at the main entry and exits. <br />c. Public corridors, when necessary, wide enough for comfortable <br />traffic flow, but not excessive to raise initial and maintenance <br />costs. <br />d. Adequate circulation aisles within the waiting area to assure <br />free movement and comfort for the room occupants. <br />52. WAITING ROOM. The waiting room is the focal point of the building <br />(Figure 10-7). It is the central meeting and waiting space for <br />passengers, visitors, pilots, and airport employees. It should merge <br />with such other required spaces as the manager's office, eating <br />facilities, and public restrooms. The closer this relationship, the <br />more economical is the building. In addition, it would be well to <br />incorporate the following user conveniences: <br />Page 54 <br />Chap 10 <br />Par 49 <br />
