Using a separate placing boom can help you realize a profit by making it easier for you to get a high-rise project done well in the least amount of time possible. Adding a separate crane may fill the obvious gap that allows you to meet your schedule, but it may also have a ripple effect on overtime costs that isn't immediately noticed. Using a placing boom instead allows you to remove time allotted for concrete placement from the crane schedule. The faster placing rates for pump placement also permit a reduced deck cycle. But to make money doing this, the time saved must then be converted to productive work.

Separate placing booms are not well-suited for every high-rise job. For them to provide full benefit, the size of the concrete pour for the deck should be at least 150 to 200 cubic yards. Column pours and wall pours, however, are almost always placed more efficiently by a separate placing boom than by crane-and-bucket methods. Location of the placing boom is dictated by the boom's working radius and by the building geometry. The pedastal for a placing boom requires blockouts in the deck, about 3 feet square. If the structure is post-tensioned, find locations where the cable pattern allows such a blockout.
