Tunstall Engineering Group specializes in:
Steel and Concrete Girder Erection
Truss Bridge Rehabilitation
Tunstall Engineering Group has performed truss rehabilitation work for both government agencies and contractors. We have performed truss analysis using 3D finite element analysis to determine member and gusset plate strengthening requirements. We have worked with contractors to develop efficient means of repairing or replacing truss members and gusset plates.
Support of Excavation
Our team has designed both permanent and temporary excavation support structures. We design excavation supports ranging in complexity from simple sheet pile walls to multi-level anchored soldier pile walls. We have also successfully performed soil nail wall designs and have experience in supporting the contractor through construction.
Tunstall Engineering offers full service bridge design capabilities. We have experience designing steel and concrete superstructures, conventional, integral and semi-integral abutments, along with single and multicolumn piers. Our resume includes bridges ranging from straight girder single span bridges to complex curved girder multiple span bridges. We also have significant experience in steel bridge rehabilitation, including steel girder and truss bridges.
Our bridge demolition experience encompasses all of the typical means and methods necessary to demolish a bridge. For deck demolition, we analyze any bridge to determine the equipment allowed to be placed on the structure. For beam and truss removal, we analyze the structure for temporary equipment and determine crane requirements.
The Tunstall Engineering Group has generated erection procedures for bridges ranging from small, straight simple span bridges to large, curved or skewed multi-span girder bridges. We have extensive experience with 3D finite element analysis to examine each erection stage for a complex bridge. We use models to determine stresses and deflections to ensure stability during erection.
Tunstall Engineering Group has performed engineering services for many bridge jacking projects. We are well versed on the many different methods of supporting a bridge, including jacking under diaphragms, from temporary towers, from temporary beams/columns anchored to the substructure, or simply jacking from the beam seat. We have the experience to design the temporary components for any jacking setup.
