water anywhere on it. This is a real accomplishment in regards to drainage and has to be seen to be appreciated. (4) The accessibility of the theatre is well-nigh perfect, being just two blocks from the main thoroughfare. There is a two lane, concrete loop road passing the entrance and exit of the theatre. This street was made one-way for the convenience of traffic to and from the theatre. This same street also aifords the theatre a 200scar holding area off the main highway.

The owners of the largest chain of drive-in theatres in the southern part of the United States, Ezell and Associates of Dallas, Texas, provided the facilities for technical research activities. The Texas firm also provided the original layout plans, by Albert Lopez, based on actual field surveys, which were taken by Rosendo B. Jurado, a prominent engineer in Panama, who also converted the final plans into the metric system. (Metric system required by law to obtain the building permits and all necessary local regulations and approvals).

At last, construction was begun by the author, using the companys own forces.

Since the general layout was designed for the acquired property, dirt moving was not much of a problem. We had exactly 20,000 cubic yards of cut embankment and 20,000 cubic yards of fill. The dirt was handled by two Super C-Tournapulls and one D7 Caterpillar Bulldozer. The bulk of the earth work was completed in two weeks. The builder wanted a certain amount of moisture to compact the fills, however (in order that the reader may understand our wet season in Panama) 3,000 cubic yards of fill on one of the slopes was washed away during the course of a one-hour shower. Steps had to be taken immediately to sod the slopes at the same time they were being constructed. This method solved the problem.

Grading After all the rough dirt work was completed, sub-grading, underground

utilities, and buildings were initiated. Sub-grading was advanced in such a manner as to maintain perfect drainage at all times. To create a water pocket or soft spot during this season of the year can hold up a job of this type for as much as two or three months. If this condition has developed and an effort is made to correct it without having proper Weather conditions, it can get bigger and bigger, until a whole job is ruined; in this event, it would be necessary to wait until the dry season in order to advance. In the dry season the weather is just the opposite of the wet season-very dry and not even a sign of a precipitation.

Since the natural fall was from the rear of the theatre toward the screen tower, and final grades called for drainage to each side of the center line and

toward screen tower, sub-grading and paving started at the rear of the theatre or the longest ramps. The soil is red clay and a 1-inch layer of quarry dust was applied as soon as sufficient subgrade was ready, for the following reasons: (1) When it rained the sections that had this application could be worked without any shut-down time. (2) The dust stabilized the soil by serving to choke off the red clay, which kept it from working its way up through the six inches of water-bound macadam pavement during rolling and compacting. This one item saved the builder many a heartache, and eliminated many shutdown hours, which would otherwise have been necessary.

All main cable arteries to ramps and speaker posts cables were then installed. Ditching was done by the same motor grader (Caterpillar #12) doing the subgrading, and at the same time pave ment grading was in process. The speaker post cable loop holes were dug by hand. The above-mentioned three phases, i.e., sub-grading, ditchingy and pavement tied together very nicely since the one grader was able to stay ahead of the rock quarry furnishing the rock for the pavement.

Pavement consisted of six inches water-bound macadam, applied in the following manner: First lift above the one inch of quarry dust consisted of crushed rock from sizes of 3 inches to 2 inches. Crushed rock of sizes from one inch to 2 inches made up the second lift, and the final lift was completed with size one inch to pea stone. RCZ Asphalt was then applied*l gallon per square meter, and a final coat of fine rock dust was then applied to serve as a binder and seal. One 10-ton and one 21/2ston roller was used during the entire operation.
