Geogrid

Geogrid

Last spring, I wrote about a great retail site with tough soils, and how we were approaching the job. Nature then turned this project into a case study in weather extremes, from the record-setting drought over the summer, to late fall monsoons. In case you are not familiar with Geogrid, it is basically a woven polymer [Read More]

Hot Weather Hacks for Pouring Concrete

Hot Weather Hacks for Pouring Concrete

We’ve reached midsummer and there’s no getting around it: It’s hot. When the temperature of fresh-mixed concrete hits 77 degrees Fahrenheit, quality is at risk, depending on the site conditions. When you get above 90 degrees in ambient temperature, you’ll have difficulty producing quality concrete without some serious adjustment to the mix. Interestingly, in the recent [Read More]

Best Practices for a Live Remodel

Best Practices for a Live Remodel

The experience one has when walking into an Apple store is unique. Clean and filled with intuitive wayfinding, I’d say. While it may seem like a lofty goal for a “live remodel,” the experience should be as similar as possible given the constraints of ongoing construction. We are currently updating the interior of a decades-old [Read More]

Why Waterproof?

Why Waterproof?

The simple answer is that waterproofing, whether around openings, under decks or in the roofing membrane, is a fraction of a building’s cost, but represents about 90% of potential problems. It’s easy not to think too much about waterproofing…Until something goes wrong. The “out of sight out of mind” mentality is easy on the front [Read More]

When the Worst Soils Are Under the Best Sites

When the Worst Soils Are Under the Best Sites

From time to time on our Florida projects, we run across sand mixed with a high concentration of organic matter. Depending on building loadings, this can be a huge challenge when selecting a foundation system that makes economic sense. Recently on a Florida site, we worked with Hayward Baker to determine if the load characteristics [Read More]

Laser Survey to Produce As-Built Plans

Laser Survey to Produce As-Built Plans

While all of our projects are special, a handful standout for one reason or another. The Thomas Jefferson, a 20-story structure completed circa 1929, was once considered among the finest Southern hotels. After closing about 3 decades ago, this beautiful Florentine building sat empty. Through the efforts of many, we are now repurposing the space [Read More]

Micropiles at the Lyric

Micropiles at the Lyric

We have been restoring The Lyric Theatre for about 9 months now, with a completion date scheduled at year’s end. To create a state of the art rigging system at the stage fly, we recently installed micropiles. They carry the load of four 65’ columns that are supporting about 25 tons of load individually. Our drilling ranged [Read More]

Don’t Leave the Basics Behind

Don’t Leave the Basics Behind

I could have titled this post something like “Remember the Right Steps” just as well. I didn’t do this recently, and it could have cost us. We have a small project of about 3000 sf, a new building on a site where a structure had been for years. I said to myself, “If a building [Read More]

Post-Tensioned Slabs On Grade

Post-Tensioned Slabs On Grade

We have a project in the works that has potential for soil movement of subgrade because of wet and dry cycles. It may require a post-tensioned slab on grade.  We will group the cables and space them throughout a slab, just as we would an elevated slab. After the concrete is poured, but before it [Read More]

Reviving Architectural Arts

Reviving Architectural Arts

In the CBD of Birmingham, we’ve been providing Construction Management services for a grand theatre that’s more than 100 years old. With structural analysis of The Lyric Theatre complete, we’ve moved ahead with the restoration of the theatre envelope, including tuck-pointing the exterior masonry and re-roofing the building structure to provide a weather-tight environment for [Read More]
