adjustments. Additionally, BIM tools allowed to speed up the shop drawing review process, by viewing the model remotely in Tekla during online meetings. Critical steel members were modeled with alignment control holes to hold a surveyor’s prism. Their 46 position was indicated in the BIM model in the form of XYZ coordinates, which were uploaded to the surveying equipment. Accurate prefabrication was the key on the Denver Art Museum, and this was greatly aided by BIM tools, such as Tekla, Navisworks, RAM Steel, etc. Construction Arup handed over their SAP2000 model to LPR’s in-house engineers to be used in the steel erection process. Initially, a wireframe was extracted from the model and manipulated in CAD to help develop the overall erection phasing plan. Then it was used to determine acceptable shoring locations for the project. Sequencing of the structure was
