Bruce Ensor, Structural Engineer started in private practice in 2002 after serving as Chief Structural Engineer for Integrated Building Arts (IBA). Before working at IBA, Bruce lived and worked in Washington DC for Skidmore Owings and Merrill and the moved to Honolulu HI on the island in Oahu. During his six years in the Hawaii, he worked as a Structural Design Engineer and Special Inspector for Martin & Bravo Inc., Sato and Associates and Shigemura, Lau, Sakanashi, Higuchi.
Bruce graduated from the Pennsylvania State University’s Architectural Engineering program/structural option, in 1986.
The Architectural Engineering program is a 5 year program which focuses on Building Design and Professional Practice for the production of Construction Documents for Buildings.
Bruce formed the Professional Corporation, BE Structural, PC in 2007 and is located in Wormleysburg, PA. Bruce was certified as a Model Law Structural Engineer, MLSE, by the National Council of Examiners for Engineering and Surveying. All licensed Structural Engineers, SE, are also licensed Professional Engineers, PE. All Professional Engineers, however, are not licensed Structural Engineers. In fact, some states have separate tests that allow Professional Engineers to be licensed Structural Engineers. Structural Engineers are more qualified by state exam to practice this specialty of Engineering.
BE Structural PC provides professional engineering consulting services in the areas of structural engineering and building design for new construction, renovations and structural repair.
Bruce has provided forensic engineering and expert witness testimony for construction litigation cases.
Bruce has been involved in post disaster structural evaluations, custom design, sustainable and non-traditional engineering. Bruce tries to see his employees as people first, staff second. Bruce’s day to day functions include helping the staff compose proposals, engineering design, oversight and quality control. His primary mission is to ensure that the firm’s first priority is to deliver quality services. Bruce continues to value and promote education and employee growth while taking BE Structural, PC to the next level. His passion for his work and his non-traditional ideas about what an engineering practice should be, have helped solidify his company’s position in a competitive marketplace. Bruce believes their future is a bright one. Bruce has three children, one of which arrived in June 2014. When he is not at the office, Bruce enjoys spending time with his family, including Boomer, the family dog.

INTEGRATED BUILDING ARTS
Foundation Failure due to Sink Hole Development Retained by an Insurance Company to assess the damage and long-term liability due to foundation failure and subsequent repair due to the formation of a sink hole. On an adjacent property the township drained a water tower to prepare to paint the inside. The water was drained out of it to a catch basin on an adjacent site. The large amount of water created a sink hole to form adjacent to the insured’s building. The loss of soils below the foundation required emerging shoring and remediation. We assessed the relevance of the construction cost and the action taken by the building owner’s contractor in review of the insurance claim and made recommendations to avoid future problems at the site.
Agriculture Building Collapse. Retained by the General Contractors Attorney. During construction high winds collapsed a wood framed agricultural building. We provided an on site assessment of the construction progress at the point of failure and made an assessment of the plaintiffs expert report as well as an assessment of the causes of failure. Our involvement aided the General Contractor’s attorney in determining the merit of the claim against his client as well as the culpability of subcontractors hired by the general contractor to erect the structure.
Arbitration of Construction Dispute. Retained by a contractor to evaluate a home he had constructed per prescriptive methods allowed by the code after the homeowner disputed additional charges and took possession of the unfinished home. The homeowner retained an inspector and claimed the roof was not adequate to support the loads and span of the as built condition.
Construction Related Fatality. Retained by an Attorney to evaluate a claim which was the result of a basement wall failure during construction. We provided expert advise and analysis for the Attorney on the technical merits of the claim relative to his client, a subcontractor on the project.
Severe Deflection in Residential Construction. Retained by the Plaintiff’s Attorney to review an existing condition. A homeowner after purchasing a $350,000 home noticed an unusual slope of the floor. The contractor had made revisions to the original design and a second floor bearing wall now sat on the first floor joists and caused the floor to sag. Our assistance led to a resolution due to the difficulty the defense felt they would have disputing our findings.

Holland Tunnel Vent Buildings Architectural and Structural Rehabilitation The buildings originally constructed in the 20’s were deteriorated. Most of the damage was exterior cracks on the mass masonry walls. The buildings were constructed from structural steel with concrete floors and shotcrete for the liners of the ventilation stacks pulling air from the tunnels. The top of the ventilation stacks were deteriorated and needed to be replaced. It was determined that it would be cost effective to replace the limestone in these areas with a simulated limestone pre-cast concrete panel. This was designed to act composite with the new shotcrete backup. The corners of the buildings are to be rebuilt using a new concrete wall and brick facade that had to match the existing stiffness of the existing three wythe mass masonry wall.
