Helical piers offer a unique foundation solution in places where traditional concrete foundations are difficult or impossible to install. Helical piers reassemble giant screws and that is essentially what they are. Their strength comes from the screw biting into soil and can be determined by measuring the torque applied to the piers. If the soil… Read More »
New Hampshire is called “the granite state,” but there is actually very little granite. Most of the rock in NH is metamorphic, not igneous like granite. It would be better to call New Hampshire “the rock state.” We have a lot of rocks. There are many New Hampshire regions where shallow bedrock and/or glacial till… Read More »
There truly is something magical about New Hampshire lake towns in the warm summer months. Kids ride their bikes to get ice cream in town, couples sip coffee on their porch and watch the morning unfold across the lake, neighbors get together to enjoy a lakeside fire in the dusk. Anyone who has spent time… Read More »
We are often asked: “do you need to inspect the structure you designed during construction?” Of course, we WANT to see cool stuff be built, and we care that it is built according to plan. But the answer, in short, is no. The 2015 International Building Code requires that many building elements and systems be… Read More »
Concrete masonry units (CMUs), still often and affectionately referred to as cinder blocks, are a common building construction material. They are economical and are often the best solution for structural elements like commercial building walls and elevator shafts. They can also double as fire protection, so they make a great choice for structural walls between… Read More »
We were recently involved with a plumbing design for a new apartment building with several design constrictions which created a challenge in selecting a water heater. In this building, each apartment needed to have an individual hot water system, had very minimal space, and was impractical to run gas piping to each apartment. This led… Read More »
On a recent project, I was asked to estimate heating and cooling costs for a variety of HVAC systems on a large new construction commercial building. My research and results lead to some very useful insight that I find myself applying to many of my projects. Let’s start with the following table from NH.gov which… Read More »
Antique hip roofs tend to have a short sagging ridge. They get flatter over time. The attic insulation, if present, has a low R-value. There are frequently broken rafters. How do we make our old homes warmer and safer without stripping off the entire roof, frame and all? The ridges sag due to historical snow… Read More »
Before In 2020, we were hired as engineer of record for a retaining wall that a contractor was building in Dover, NH. The previous wall was collapsing because of age and the effects of frost/ thaw. We were able to subcontract completion of the wetlands/ environmental permits and preliminary wall design. Then, we ensured that… Read More »
Your building has cracked foundation walls. Is the foundation settling? Are the cracks structurally significant? What’s the problem, what’s the repair, and how much will it cost? Who can do the work? Initially, Team Engineering performs an assessment of the structural significance of foundation problems and contributing factors. If your home is constructed on a… Read More »
