Children Will Fall At Playgrounds. What Shall We Do To Protect Them? A Multipart Blog Series – Part I

Co-Authored with Aron Olson, PE   

In 2011, a 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman’s pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy. Read More

Uninvited House Guests: Mold and Other Fungal Growths

Author

The wet, relatively warm weather recently experienced in the southeast has caused a high incidence of mold and other fungal growth complaints in homes and other structures.  Engineers at Warren Group are often called upon to investigate the cause(s) of these problems. Read More

Air Conditioning Evaporators

Author

This is the third and final of three articles concerning the basics of air conditioning systems.  This article concerns the evaporator, a part of the air conditioning system that is usually unseen inside the air handling unit. The evaporator, in concert with a fan, supplies cool air to a building interior. Read More

Air Conditioning Condensing Units

Author

The condensing unit is a key component of all vapor compression air conditioning systems.  We are all familiar with condensing units as the noisy exterior portions of air conditioning systems that blow hot air to the environment. Read More

Air Conditioning System Basics

Author

Air conditioning systems are everywhere in our lives – at home, in our vehicles, at work, in manufacturing facilities – yet most people give them little thought other than setting a comfortable temperature until they stop working or malfunction in some other way. 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

Collapses of Decks, Balconies and Railings: An Engineer’s Viewpoint for an Adjuster

Author

Most failures of decks, balconies and railings can be avoidable if properly designed but when a collapse occurs it usually leads to personal injuries and even death. According to the North American Deck and Railing Association (NADRA), “It’s estimated that 2.5 million new or replacement decks were built last year.  Almost every new home being built today includes an elevated deck or porch. And, existing decks on older homes are being replaced at a very high rate. In fact, the number of personal injuries and deaths related to decks each year is likely to continue to rise because more decks are being constructed each year and existing decks are deteriorating.” Let’s examine the design, construction and inspection of these systems.

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
