Cefali& AssociatesContactAt Hollywood Burbank Airport's replacement terminal parking structure, new utilities occupied ground needed for shoring anchors. Cefali & Associates modeled the shoring in Revit and coordinated tieback clashes with utility trade partners in Navisworks.
Cefali was the design arm of Malcolm Drilling's design-build team for the parking structure. Its shored excavation supported a one-level below-grade structure with large foundations and over-excavation requirements, so anchor coordination was part of a wider excavation and construction plan.
Site conditions
Tiebacks extend into the ground behind the shoring. A utility crossing that space can restrict an anchor's location, length, or angle. At the airport project, Cefali coordinated the shoring model against utility trade models to identify those conflicts.
The shoring had to accommodate large foundations, over-excavation, existing structures, proposed grades, and new retaining walls. Anchor positions and wall support therefore had to be considered with the surrounding work and the construction sequence.
A coordinated model helps the team examine the space anchors and utilities need. Tieback design also depends on geotechnical criteria, drilling access, and available property rights, which establish whether the proposed anchor arrangement can be used.
Published project work
Revit shoring models and Navisworks coordination addressed tieback conflicts with utility trade packages for the airport parking structure.
Engineering scope
These projects show how excavation depth, neighboring structures, access, and the permanent work can change the support design. Your site needs its own geotechnical criteria and structural design. The contractor determines installation and construction means and methods.
