Abstract: A method, system, apparatus, and computer program products provides the ability to dynamically define and generate inlet spacing along a road in a building information model (BIM) computer aided design (CAD) three dimensional (3D) model. A representation of a road is acquired in the BIM CAD 3D model, wherein the representation includes a geometry. An inlet spacing is defined for the road. Inlet locations for inlets are determined based on the inlet spacing. A determination is made regarding whether the inlet spacing and inlets satisfy design rules for the road. When the inlet spacing and/or inlets fail to satisfy the design rules, a different inlet spacing is selected from a group of preset integers, and the process repeats until the design rules are satisfied.

Abstract: A method, system, apparatus, and computer program product provide the ability to design a drainage pipe solution. A profile of a surface segment (that includes a surface slope) is acquired. A first pipe size and a first pipe slope or calculated based on a proper velocity. A second pipe size and a second pipe slope are calculated based on the surface slope. A first pipe covering and a second pipe covering for the first pipe size and the second pipe size, for the surface segment is computed. A lower of the first pipe covering and the second pipe covering is selected as the drainage pipe solution.
