Features Renovation of Baltimore's Historic Hippodrome Theater

Dealing with unexpected job conditions midway through a project is a challenge for any contractor, especially when there’s not enough time or money to make the changes. Because of its extensive experience and by using creativity and management skills, Structural Preservation Systems, Inc. (SPS), one of the specialty contractors for Baltimore’s historic Hippodrome Theater renovation, was able to meet the challenge head-on. By performing structural concrete repairs on this $56 million project, SPS helped set the stage for success. Read more

Features Looking Inside a Concrete Bridge

Many of the nation’s bridges lack adequate load ratings, and for older bridges, construction drawings are often missing or incomplete. Recent advances in nondestructive testing allow us to develop an image of the internal construction of concrete bridge members to determine the dimensions and the location of internal reinforcement. Ground penetrating radar (GPR), in particular, has become a powerful aid in developing as-built drawings for existing bridges. Read more

Features Concrete Contracting 101

When you get a half dozen contractors talking about the business of concrete construction, two things are clear: They are passionate about what they’re doing, and they each have their own unique ways of solving problems. For the third year now, Concrete Construction hosted an Industry Trends Roundtable, where we invited contractors and representatives from the supply side to talk with us about the issues facing the industry.

Residential Concrete The New Prairie Home

The New Prairie is the name we gave our prototype concrete home built in Racine, Wis. It aims to make quality architectural design more affordable than most architect-designed homes today. We believe in integrating quality design with concrete construction technology, providing a better way of building that satisfies the homeowner’s aesthetic as well as technical and functional needs.

Residential Concrete Windows for Concrete Homes

Wood-built “stick” walls come in two sizes: 2x4 with plywood on the outside and drywall on the inside to create a wall thickness of 4 5/8 inches, and 2x6 that provides a total wall thickness of 6 5/8 inches. This makes it easy for window manufacturers to produce standard jamb depths. And since windows in wood-frame construction are always set in wood, installation is relatively easy. Many window manufacturers make installation even easier by attaching a plastic “fin” in the window jamb at the right depth. The fins come with predrilled holes for screws or nails, so workers can quickly position the windows flush with the wall surfaces and fasten them. Read more

Residential Concrete Floors with Options for Design

Concrete floors have been around for a long time and the public has often dismissed them as boring and utilitarian. But homeowners today are discovering the attractiveness and range of possibilities in concrete floors. One motive for choosing a decorative concrete floor is that each is unique—your floor is guaranteed to look different from anyone else’s. When contractors, designers, and owners work together, the results can be creative and stunning. Even old, worn slabs, full of cracks or pock-marked from years of abuse, can be attractive, and the distress may actually make the end result more aesthetically pleasing. Read more

Although there are many advantages to designing with insulated concrete forms (ICFs), at Living Architecture we specify them for one overriding reason—health! Read more

Residential Concrete Concrete Home Building Council: The Ultimate Resource

The residential concrete building market is diverse and disorganized. Traveling across the country you’ll find communities built entirely of concrete, while in others, concrete’s role is limited to foundations and swimming pools. Concrete is an essential building material in residential construction, and the industry is growing, literally, from the ground up. But, where can builders, contractors, and architects turn to find the latest techniques, navigate the maze of code-compliance, and find similar-minded businesses across the country? The answer is the National Association of Home Builder’s Concrete Home Building Council—an organization that keeps track of the entire residential concrete industry, the ultimate resource for all things concrete and cement-based.

Some people prefer the look of natural colored concrete. But they also want it to be decorative or “architectural” -- providing special interest to a design. Read more

Decorative Concrete Preventing Moisture Problems

More people are choosing insulated concrete walls than wood frame walls in residential construction. Concrete homes can be constructed with insulating concrete forms (ICF), cast-in-place concrete, precast concrete panels, autoclaved aerated concrete, and concrete masonry. These construction methods generally lead to energy-efficient homes due to their thermal mass, high levels of insulation, and low air infiltration. But because of the low air infiltration, controlling moisture is important. Read more

Problem Clinic How Low Can You Go?

In our area it seems like there is more and more pressure to use very low water-cement ratios, which our finishers say is making the concrete hard to finish. What is the lowest water-cement ratio where we can still expect good finishability? Read more
