Restoring NBIS Compliance Through Large-Scale Foundation Evaluation
BDI partnered with the Louisiana Department of Transportation and Development (LADOTD) to evaluate the foundation configuration of nearly 350 bridges across Districts 02 and 62 as part of the agency’s ongoing bridge inspection and asset management program. Because each bridge carried an Unknown Foundation rating from previous inspections, the LADOTD needed to determine foundation data…
Read MoreEvaluating Unknown Bridge Foundations Across Texas with Ultraseismic Testing
The Texas Department of Transportation (TxDOT) contracted BDI to evaluate unknown bridge foundations at 48 bridges across Texas. As part of TxDOT’s bridge inspection program, the project focused on assessing foundation condition and scour vulnerability to support National Bridge Inspection Standards (NBIS) reporting requirements. To gather critical foundation data, BDI performed detailed field inspections and…
Read MoreTelecom Tower Foundation Evaluation
Telecom tower owners rely on accurate foundation information to support asset management decisions, structural analyses, and antenna upgrades. When design drawings are unavailable or unreliable, BDI helps owners determine foundation dimensions without costly excavation. For more than a decade, BDI has performed unknown foundation investigations for telecommunications infrastructure using advanced nondestructive testing technologies. Engineers first…
Read MoreUltrasonic Testing of Spillway Gate Anchor Bars
BDI was contracted by the Grant County Public Utility District to evaluate the condition of spillway gate anchor bars at Priest Rapids Dam in Washington State. As a key component of the Columbia River hydroelectric system, the dam relies on these concrete embedded anchor bars to safely support and operate its spillway gates. Because the…
Read MoreUHPC Overlay Bond Strength Evaluation
The Delaware Memorial Bridge, which carries I-295 across the Delaware River between Delaware and New Jersey, is a critical transportation link for the region. As part of preservation efforts the Delaware River Bridge Authority had an ultra-high performance concrete (UHPC) deck installed on the bridge deck. To evaluate the effectiveness of the repair, BDI was…

BDI partnered with engineers to support a routine National Highway Institute (NHI) bridge inspection of the I-380 Bridge over the Delaware and Lackawanna Railroad near Scranton, Pennsylvania. The bridge’s complex geometry and challenging access conditions made traditional bridge inspection methods less efficient, creating an ideal application for drone-based bridge inspection technology. To improve inspection coverage…

Read MoreDiagnostic Load Testing for Bridge Load Rating
Introduction Ask any bridge engineer and they will tell you that a load rating is only as good as the assumptions that it’s based upon. When evaluating bridges, load ratings performed using traditional analysis methods can sometimes be overly conservative and result in unnecessary load restrictions. Section 8 of the AASHTO Manual for Bridge Evaluation…
