"We provide a full complement of engineering services to support heavy movable structure projects, from inspection to design to field construction support."
— Paul Bandlow, Principal and Unit Manager
Not all structures are built to remain stationary. Some are designed to adapt to the dynamic demands of the built environment. Stafford Bandlow Engineering (SBE), a division of WJE, is the industry leader in design, inspection, and repair of heavy movable structures, including bascule, swing, and vertical lift bridges as well as dam gates, locks, ferry slips, and cranes. For three decades, SBE engineers have worked with owners, contractors, fabricators, and installers to deliver technically sound and cost-efficient solutions for movable structures.
SBE and WJE are committed to finding practical yet innovative solutions to the structural, mechanical, and electrical problems experienced by all types of heavy movable structures. Our engineers are experts in the design of new systems, rehabilitation of existing systems, shop inspection, field inspection, preparation of procedures for machinery installation, strain gage testing for bridge balancing, and electrical testing and construction support services. SBE is knowledgeable in the governing AASHTO, AREMA, and CHBDC standards for highway and rail bridges and routinely troubleshoots problematic conditions on both scheduled and emergency bases.
Supported by extensive in-house testing and research capabilities in WJE’s Janney Technical Center, SBE engineers perform a wide range of field and laboratory testing services. From full-scale load testing to elemental material analysis, SBE and WJE provide clients the answers they need to maintain the integrity and safety of their movable structures and equipment.
