Portable concrete pump is a tool used to pump concrete towards casting locations especially when the locations could not be reach by truck mixers. By using portable concrete pumps, concreting process can be finished quicker. This study begin with elaborating information about factors affecting the concreting process such as equipment and machinery for pumping, standard procedures for placing concrete and other requirements. The relation between productivity of portable concrete pumps and horizontal range, as well as the height of the casting location, is derived from project observation and data collection. Further calculation and analysis shows the regression equation for portable concrete pump productivity is obtained as Y = 1.0546 – 0.00351 X 1 –0.00181X 2 with X 1 is floor height and X 2 is horizontal range. The difference in productivity during productive time and total time that is affected by delays is 0, 044 m 3 /min or the effect of delay time to concreting productivity is 8.7% compare to productive time.
