Tarsco utilizes an extensive and efficient procedure to build tank dome and elliptical roofs near the bottom of the tank and then air raise them into final position. This procedure allows most of the roof erection work to be constructed at a low elevation, resulting in a high quality roof as well as limiting personnel exposure to dangerous heights. Large tank dome and elliptical roofs in the range of 75’ to 350’ diameter, weighing up to 1,000 tons, with heights over 150’ often utilize this air raising procedure.
