Pretty sure gINT has a tablet ready software whereby data is entered into drop down boxes at site. Uploading back in the office automatically generates all the requisite logs and data sheets. HoleBASE (Keynetix) have certainly been doing the same for years, I used Pocket SI around 10 years ago...

understood, people caveats on this forum are always longer than their technical advice not without good reason though given some of the perceived levels of understanding based on some OP's! cant see anyway round handheld plant for compaction. a hydraulic plate on the end of a long reach might...

No experience but what just thinking about the issue. A targeted grouting scheme from the surface around the existing pipe location/shaft interface could significantly reduce flows in that area once you excavated out the shaft and approach it side on? As with any grouting scheme however the...

smaller plant = smaller weights = smaller layer thickness = more time + cost thinner layer thicknesses may make the use of handheld compaction plant (whacker plate type) feasible dependant upon the fill material. as others have pointed out, its a pretty basic observation to have made when...

Thanks for the replies. The issue at hand has been missed somewhat, likely due to my explanation! We have already drilled through revetment elsewhere, using bauer spezialtiefbau piling equipment however this work was installing steel column grouted piles. Obviously the steel column also acts as...

the issue here is more a lack of confinement. Contractors current proposal seems to rely upon the geomembrane providing all confinement to pile concrete as quarry run and armour will provide little to none once the temporary boring casing is withdrawn. I've called the contractors sub-contractor...

Concept design is for a secant piled wall to construct a seawater intake structure on an offshore reclaimed island. bored cast in situ piling is prevalent in the region and more importantly the equipment is available at the remote site. Contractor is unable at this time to provide a detailed...

BS 5930 or its Eurocode replacement has the detailed section on precise word placement and the outline parameters for descriptors.

Apologies............ http://en.wikipedia.org/wiki/Mosul_Dam

Admit to be totally astonished at this story having seen the Dam in recent headlines. Not a query of any sorts but simply an interest piece for digestion. Quite what they are aiming to achieve by continuing the grouting for such a length of time I have no idea. At least one of the references...

Excavation for 1M barrel tank producing soils with gypsum content 7-26% by weight, water soluble sulphate content is 0.72-2.81%. Spec, probably mistakenly, prohibits more than 5% gypsum in subgrade beneath tank. I suspect the intent of the clause was to capture soluble sulphate content of 5% and...

Is there value depends largely upon the planned development. Ive used ERT extensively in the middle east looking for solution features but its not always appropriate, check with some local geophysical contractors. Be sure to look out for saline groundwater as this has had significant impacts on...

UK Specification for Highway Works 1992 includes a useful table that relates material type (need to select type from the given table) to appropriate types of plant given a maximum layer thickness and number of passes. No substitute for a site based compaction trial but a good starting point...

heat index can also refer to lcoal or regional index relationships. in the middle east we have a index chart of temp vs humidity, index values from this chart above 54 mean work in direct sunlight has to cease, above 48 there are specific requirements for rest periods and fluid intakes etc.

In the UK as a graduate there are three defined routes into the industry i would say, Contractor, Consultant and Laboratory. all 3 have merit. i went into consultancy which gave me good exposure to contractor work as i was specifying their works and standing next to them a lot but the pay is...

1. I kind of fell into studying applied geology at university as undergrad and really enjoyed combining the elements of problem solving whilst having an outdoor, hands-on role. Im not sure i can claim to be 'passionate' about geotech but i still enjoy that combination of challenges ot this day...

CVG/BigHarvey - 65%RD (dependant upon how you calculate RD!!) is similar to many of the similar schemes around the region including Palm Jumeirah in Dubai and plenty other far less famous sites. Admittedly most of these projects require additional ground improvement and review for specific...

Cvg- testings been commissioned and I now have the results however the letter response to the contractor couldn't wait so I had to word my supposition accordingly. I was hoping for a sanity check of my opinion based upon what I knew at the time.

not sure the exact document you're referring to but Lunne & robertson's work is a good strating point. Peter Robertson website also has links to documents for download...... http://www.cpt-robertson.com/
