While nosing around in Geosynthetica's archives, we happened upon an interesting photo (dated 2004) of Ian Peggs conducting a liner integrity survey while suspended from a crane. Though liner integrity surveys are common, the conditions in which they must be conducted vary wildly. We asked Dr. Peggs if he might offer a few notes about this particular situation. Here's what he shared with us. Read more.

ASTM Committee D18 on Soil and Rock, WK29134, is a work item for "New Terminology for Hydraulically-applied Erosion Control Product (HECP)." The scope is to provide a definition for an hydraulically-applied erosion control product (HECP). A material definition is important to the consumer so that they purchase a product that will meet their intended need. The definition would be built into material specifications for hydraulically-applied fiber products. DOTs, landscape architects and civil engineers would utilize the definition in drafting material specifications. Learn more here.;

The lengthy and acrimonious legal dispute between Tampa Bay Water and engineering firm HDR is not necessarily over, but HDR has come away victorious from the first trial. TBW has been convinced HDR's design and quality control led to excessive cracking of 15.5-billion gallon reservoir--cracking so severe a new reservoir (and liner) is being planned. An interesting article over at ENR details the complexity of the dispute, from the difficulty of proving excessive pore pressure to soil compaction questions. Learn more here.;
