THE ANALYSIS OF SLIP FORM CONCRETE PAVING USING TIMELAPSE PHOTOGRAPHY
The report demonstrates that timelapse photography is a viable method of performing studies of slip form paving operations. An attempt is made to develop instructional guidelines which a contractor unfaimiliar with timelapse photography techniques could use in taking and analyzing high-quality timelapse motion pictures. Three different slip form paving operations were analyzed using time-lapse photography as the primary method of data conection. The reaction was determined of construction management toward timelapse photography as a method of studying slip form paving operations. The nature of timelapse photography is described and the movie equipment which is required, is discussed in detail. The timelapse Mark III movie camera which uses 8 mm film has many features which make it particularly well suited for analyses of this type. The timelapse Mark III movie projector permits an accurate analysis of the films. A conventional super 8 mm film editor can also be used in the analysis of timelapse films. Details are given of the filming techniques. Data collection in the analysis of slip form paving projects is reviewed and a description is presented of the projects. The basic methods of analysis used in the study are outlined. They include: determination of cycle component times in the paving cycle; determination of interservice times in the slip form paving cycle; determination of utilization factors for the batch plant and paving train; and the determination of delays in the slip from paving cycle. An investigation of construction management reaction revealed that office managers expressed favorable interest while field managers expressed less favorable interest. The methods which must be understood and followed in order to insure high quality timelapse motion pictures of a slip form paving operation are listed. The information that was determined for each paving operation is also listed. The results of the analysis of the three operations are tabulated.
