Officials with the foundation drilling and construction company called results "very unsatisfactory."

A UK company have developed an innovative drilled pile that integrates closed geothermal loops.

 Vermeer unveiled its D220x300 Navigator horizontal directional drill at the recent 2013 International Construction & Utility Equipment Exposition in Kentucky. 

 In my last column, we discussed the value triangle as it relates to developing a cost estimate. This month, let’s talk about another form of estimating: the ubiquitous “budget estimate.” As contractors, we all have been asked to provide this type of cost, which can also be termed a “ballpark estimate.” Before we go into more detail, let’s define the term; and, as always is the case, the definition is in the eye of the beholder.  

 In a perfect world, drilling fluids for each project would have exactly the right properties for the job at hand and the work would go as planned. But, sometimes, changing conditions downhole—e.g., shale, rock, sand or salt—require further modification in water loss properties, rheology control or viscosity modification.  

Anderson Drilling is a respected and experienced foundation contractor known for tackling big foundation jobs in California. Anderson operates a high-quality and well-maintained fleet of foundation drills and cranes, and the traditional tooling capable of completing these often monumental projects. In order to be more efficient in the recent downturn in the construction economy, Anderson looked at newer technology, specifically Atlas Copco’s 48-inch cluster drill, as a way to speed up the foundation drilling process.
