Laser Scanning: A Better Way to Analyze Concrete Slab Flatness

Most of the methods used today for conducting slab flatness analysis are manual and labor intensive. Floor flatness/floor levelness (FF/FL), a commonly used method, requires the creation of a grid on the concrete slab following a set of specifications before taking manual readings. Contractors that use the ASTM E1155 standard method for determining floor flatness (FF) and floor levelness (FL) numbers typically take a measurement every foot along the grid lines. Using this method, even small projects often require a substantial amount of time to complete the data collection and analysis. Recently, however, contractors have begun to discover a new way to save a substantial amount of time and money on their projects: laser scanning.  Continue reading…

Two Hot Trends to Watch at World of Concrete 2015

Exciting things are happening in the concrete industry, driven by the emerging requirements of owners and general contractors to incorporate intelligent 3D model based design into layout and construction to reduce costly rework and keep projects on schedule. The World of Concrete show in Las Vegas next month – one of the top shows in the industry – is projected to be the largest in six years with 1,300 exhibitors and over 630,000+ square feet of exhibition space. In addition to all of the newest products and equipment, building information modeling (BIM) – incorporating intelligent 3D design models into construction and layout, and utilizing high definition scanning before and during construction to compare as-built to as-designed – is a hot trend in the concrete industry that will get a lot of attention this year.

‘Heat Mapping’ Irregular Floors

Many of our interior build-out projects are in existing spaces, and these spaces often have their fair share of challenges. One recent challenge included an irregular concrete deck with low spots, coined “bird baths.” At the end of the day, this floor had to be leveled. Continue reading…
