The base price is $4125 (US) or if you need greater GPS accuracy, you can buy it bundled with Trimble’s GPS Pathfinder ProXT or ProXH bluetooth connected GPS receivers for $5495 or $6495, respectively. And you might want a few accessories, like an office docking station (pictured at left for $749), vehicle charger ($189), ruggedized keyboard ($395) and some other things as well. I don’t do any GIS stuff, but I presume you’ll need some kind of Trimble software to manage your GPS data collection efforts, that can add up quickly as well. If you want one like I do and happen to have $5-10K to blow, check out the Yuma Ruggedized Tablet PC at the Trimble Store.
Another busy month for ASTM with 66 new, revised or otherwise updated standards related to geotechnical and geological engineering (although not as busy as last month). A couple that caught my eye include brand new standards for geospatial data requirements related to abandoned mines, a new standard for sampling of EPS or geofoam, updated standards for mortar and cement, flexural strength of concrete, LA Abrasion test for aggregates, acceptance testing of geosynthetic clay liners, electrical methods for leak detection of geomembranes with earth cover and classification of soils and soil-aggregate mixtures for highway construction purpose (AASHTO classification).
Those involved in the materials testing side of the business should take a close look at the full list as there are also a number of updated standards relating to various asphalt and and aggregate tests, capping of concrete cyllinders and other related testing standards.
For my practice, perhaps the most significant standard that was updated was D 2488 – Standard Practice for Description and Identification of Soils (Visual-Manual Procedure) which we rely on for our field USCS classifications. I’ll be curious to see what those changes entail. Click through for the full list.
