The erection and installation procedure called for a maximum panel-to-panel joint tolerance of 1.27 cm 0.5 in., often in 90° joints between panels. The residence comprises of 108 precast concrete panels of varying rectangular shapes with ' dog legs ' and window and door ' cutouts ' that look like an assembled jigsaw puzzle. This paper presents the concept used to construct a complex residential tilt-up-panel structure utilizing three-dimensional 3D modeling and animations. At last, a case is represented in order to demonstrate the use of the developed algorithm and to illustrate its essential features. The algorithm is incorporated into a three-dimensional 3D computer-aided system that integrates crane selection module, crane modeling module, 3D-simulation module, 3D computer-aided design modeling module, rigging calculation module, and data management module. This paper presents a newly developed algorithm for selecting mobile cranes on construction sites, which takes into account the lifting capacity, the geometrical characteristics of the crane, the dimensions of equipments and riggings, and the ground bearing pressure. It is a tedious job that lifting planners select cranes for construction projects based on a large number of lifting capacity charts. These charts are structured based on predetermined crane configurations, which consist of boom/jib length, lifting radius, main boom angle to ground, and jib angle to ground or its offset to its main boom centerline. Lifting capacity charts are tabulated and provided to operators and practitioners by mobile crane manufacturers.
