Reducing Property Damage and Injuries Via Near Miss Reporting

What is a near miss?  It’s an unplanned event that does not result in injury or property damage, but had the potential to do so.  We often call these events “close calls” or “narrow escapes.”  For example, a scaffold guardrail is missing, a worker backs up and as he starts losing his balance, he is able to grab hold of the scaffold buck and prevent the fall.  Other than a racing heartbeat for a few minutes, presumably, no harm, no foul.

Post-Fire Inspection of Steel, Concrete, Masonry and Wood – Tips for an Insurance Adjuster, Part 2

Author

This is the second part of a 3-Part series to help insurance adjusters during a claim inspection to make a post-fire assessment of a building’s structural framing system.  Part 2 investigates and assesses the future use of common post fire structural framing elements such as steel, concrete, masonry and wood.  These more common structural elements take on different and specific characteristics when they are exposed to a fire.  It’s important for the adjuster to make reasonable, cost saving assessments on what remains, what is to be repaired, what gets demolished and what gets replaced.

Structural Evaluation After a Fire – Post-Fire Tips for an Insurance Adjuster, Part I

Author

This is a 3-Part series to help insurance adjusters during a claim inspection make a post-fire assessment of a building’s structural framing system.  From my numerous case history inspections involving damage to structural framing members after a fire, what appears obvious and straightforward is not always the case.  This article is a quick synopsis to help the adjuster be better prepared for a structural inspection and assessment while understanding what needs to be looked at, and if there are hidden factors to further investigate.

Not Falling for Your Job?

Periodically, Warren Engineers and Consultants are asked to perform inspections that require work at raised elevations. Typical jobs and tasks include climbing on commercial and residential roofs with steep pitches, working on scaffolding, climbing from one level to the next at a fire or industrial loss scene, riding in the buckets of lift equipment, and inspecting exterior structural elements such as windows and masonry.  Read More

Water Intrusion/Moisture Issues – Finding the Source and Location

Author

What you see is not always what you get.  This commonality exists in the numerous cases I have investigated for water intrusion and moisture issues in buildings.  The source that appears most obvious and straightforward may not, in fact, be the root of the problem at all. Read More

Identifying Foundation Issues for Adjusters

Author

As a structural engineer, I am often called upon to determine the cause of commercial and residential building problems. Common problems I investigate include doors or windows that don’t open properly, cracks in interior and exterior walls, gaps in the trim, leaking roofs when the exterior covering is otherwise in good condition, sloped and out-of-level floors and leaning walls. Many of these problems are a direct result of foundation cracks, settlements and/or failures. Read More

What is a Building Envelope?

Author

By definition, the building envelope (or building enclosure) is the physical separation between the interior conditioned areas and the exterior environment space of a building. The envelope serves as the outer covering (shell or skin) to help maintain the indoor environment together with the mechanical conditioning systems and to facilitate its climate control. The building envelope must be carefully designed with regard to site specific climate, ventilation, and energy consumption within the structure. The design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control. Read More

Metal Decking Provides for Building Stability and Worker Safety

Author

It’s simple, right?!  Buildings being constructed must maintain a structural stability at all times during the steel erection process. That’s according to OSHA Federal Register Subpart R 1926. OSHA also reminds us that “Since structural collapse is second only to falls as a cause of fatalities in the construction industry, stability is essential to the successful erection of any steel structure, including single- story, multi-story, bridges, etc.” Let’s further examine what goes into the erection and installation practice for roof or floor metal decking as a safe working platform.

Snow/Ice Accumulation Leads to a Roof Collapse

Author

During the next several months when temperatures start to fall below the freezing point and winter storms packing cold temperatures, heavy snowfall and ice build-ups bear down on various regions of the country, they can and do bring an assortment of unfavorable conditions that could and will affect your insured’s buildings, businesses, and personnel. Some of these regions have already experienced record-breaking snowfalls and bitter cold temperatures, which in turn have increased the danger of roof or partial roof collapses. Roofs that are properly designed and constructed to applicable codes and standards should be built to withstand loading from snow, drifting snow, water-laden snow and ice build-ups. But are they? Building codes and standards that depict the proper roof loads will vary across the U.S.  They will generally be based on local historical data, including the expected frequency and intensity of these winter storms in a particular region as shown and discussed in ASCE 7-10.

Stormwater Management Systems – Flood Control Structures

Author

An integral part of a stormwater management system is the design.  The design controls the quantity, quality, timing and distribution of storm runoff.  The storm drainage system is a network of access structures, ditches, channels and underground pipes that work together to direct and carry stormwater (rain and snow water) to ponds, lakes, streams and rivers and may consist of both public and private land and systems.  In order to keep these stormwater systems working properly as designed, the systems must be maintained on a routine schedule and on a continual basis.  The maintenance of these systems involves rigorous cleaning and removing of vegetation and debris. The systems include but are not limited to culverts and pipe outfalls, catch basin gratings and manholes, retention and detention water runoff control basins, channels and roadside ditches, and underground piping.
