Government agencies and construction firms are recognizing the significant benefits of an accurate map of underground infrastructure for construction projects. Here we describe how accurate models of underground infrastructure bring practical benefits to construction projects. […]
A revision to the PAS 128 2014 standard for locating underground utilities is available for public comment through March 16. PAS 128 defines a hierarchy of detection methods for detecting underground utilities in terms and […]
The release of the new ASCE Standard Guideline for Recording and Exchanging Utility Infrastructure Data (also referred to as the utility as-built standard) developed under the auspices of the American Society of Civil Engineers (ASCE’s) […]
With about 55,000 substations in the U.S. and the average age of the transformers in these substations over 40 years old, many substations are going to be refurbished, retrofitted, extended or upgraded. Utilities are opting […]
Currently best practices for recording the location of new underground infrastructure is to survey it after installation and before covering the trench. Appropriate survey tools are total stations, RTK, and LiDAR. However, trenchless technology is […]
Unforeseen ground conditions are a major cause of delays in construction projects. This year, at Bentley Systems’ Year in Infrastructure Conference, Roger Chandler, Director of Geotechnical Information Management, announced OpenGround, a collection of applications for […]
I had the opportunity to attend the 1Spatial Smarter Data Smarter World conference in London. A presentation by Seb Lessware, CTO of 1Spatial, of Realworld 4D for BIM and facilities management demonstrated an impressive integration […]
Traditional output from a GPR scanner showing hyperbolas reflected from underground utilities The major inhibitor to broader use of ground penetrating radar for detecting the location of underground utilities is the difficulty in interpreting radar […]
