Pre-engineered metal buildings have been built for decades and are growing in popularity. “Pre” engineered is a bit of a misnomer – our experience these days is that the buildings are engineered as part of a typical design process, and just designed by someone other than the structural engineer of record. The manufacturers of the… Read More »
This rooftop patio had been leaking for years. It had a concrete deck surfaced with DEX-O-TEX, which was a textured “rubber” membrane type product. The DEX-O-TEX and miscellaneous patches were removed and a new two-part liquid membrane coating system was applied by Viking Roofing of Hollis, NH (www.vikingroofingnh.com). The installed product consisted of Sikalastic RoofPro… Read More »
So many great things came out of 2020. One of the many is that our long-time friends at 101-103 School Street Condominium in Concord said yes to proceeding with needed structural improvements to this “multi-level” garage. For many years, the cars on the upper level would drip salt and sand through the old wooden floor… Read More »
As engineers, we often get the call to inspect and design improvements for structural members that are close to failing. Building owners often catch these deficiencies before the worst-case scenario comes to life. Surprisingly, we rarely see any that have actually failed, but this is one of them. The age of this home is unknown,… Read More »
Recently we have been asked a lot about fiber reinforcing, and if it should be used in concrete slabs-on-grade. Fiber-reinforced concrete, or FRC, is a common building structural element, and it consists of cement, sand and aggregate, and very small fibers. The fibers can be made from steel, glass, synthetic/polymer materials, or natural materials like… Read More »
A common concern we receive from owners of older homes is a sagging/sinking floor. Sagging floors can occur for several reasons and might be scary for homeowners, but a qualified engineer knows exactly what signs to look for to determine how to fix it. All structures settle over time (especially in the first few years)… Read More »
Around here, most residential garages, whether attached to the house or detached, include a concrete slab-on-grade. Concrete slabs-on-grade are strong, durable, and easy to maintain. To provide more usable square footage, garage floors are sometimes built elevated – we’ve designed a few ourselves using framing systems like cold-formed steel joists, pre-stressed concrete plank, and structural… Read More »
It is more important than ever to provide fresh and clean air to indoor spaces. Providing ventilation to protect occupant health and wellbeing in a building is not only best practice but also required by code. Chapter 4 of the International Mechanical Code dictates the ventilation requirements for both residential and commercial buildings. There are… Read More »
Structural engineers design buildings to withstand loads of all types. The building’s frame must be designed to withstand a combination of all those loads with some being more present than others, such as snow or seismic, depending on the geographic region of the building. The most common loads we address within New Hampshire and Massachusetts… Read More »
