GeoEngineers recently suggested that one of our long-time energy market clients consider Direct Pipe™ (DP) for a difficult interstate highway pipeline crossing. DP is essentially a curved or directional microtunnel that utilizes proprietary equipment developed by Herrenknecht Tunneling Systems in Germany. Less than 20 of these installations have been made in the world (most of these in […]

If you have a critical structure that is supported on or above steel mill slag, be aware that the structure may experience significant differential movement problems for years after completion of construction. Great care should be taken if steel mill slag is being considered for use as structural fill for construction projects. Slag is a […]

The Washington State Department of Archaeology and Historic Preservation (DAHP) recently launched the Historic Property Inventory (HPI) module for the award-winning Washington Information System for Architectural and Archaeological Records Data (WISAARD).
