Thermal Effects In Piping Systems

Have you ever turned on the hot water faucet and after a short period of time, heard creaking noises coming from inside the walls or below the floor? While such noises could be unwelcome guests, such as rodents or space aliens, chances are, the noises are being generated by thermal-related pipe...

Is Transformer Gassing Damage?

Key gases are defined as gases generated in oil-filled transformers that can be used for qualitative determination of fault types, based on what gases are typical or predominant at various temperatures...

Why Is My AC Leaking Water?

EDT

As summer approaches, air conditioners around the country will start running over time. With that increased usage and warmer weather, instances of water damages related to the operation of “ACs” will increase. In this article, we will review two ways that water damages can occur from an AC.

Pressure Beyond Limits

You may be familiar with the consequences of applying too much air pressure to an item such as a balloon or a tire. Most people intuitively understand that there is only so much air that can be added to your car tires before they burst. Items that are designed to contain pressurized gases or liquids...

Why Is My Building Cracking?

The design and analysis of the foundation system are equally important to provide support to the building. However, more often than not, an adequate investigation, design, and preparation of the ground where the structure and its supporting foundation system are to be built are not taken into...

When the Curtain Falls

In our previous blog post, Not So Good Vibrations (Part I), we discussed waves related to blasting type applications as well as why we perceive vibrations from blasting inside our home and not outside. In this blog post we will discuss the question, can vibration responses from nearby blasting...

Oxford Dining Hall Beam

When learning about scheduling in college, one of the best examples of construction management and scheduling involved the repair of timber beams in a very old building in England - the Oxford Dining Hall in New College, a constituent college to Oxford University.

Fire on the Move

Some mining operations install large-scale conveyors, called overland conveyors, as a cost-effective alternative to trucks for the movement of aggregates over long distances, with lengths measured in miles rather than feet. The typical overland conveyor travels at speeds around 1,000 feet per minute...
