A soil boring identified an organic layer approximately 2' thick approximately 8' below grade. Bottom of proposed spread footing is approximately 3' below grade. Structure is 2 story residential dwelling. Material above and below this layer is medium density sand. When consulting the Bousssinesq...
Are there any standards which dictate the minimum amount of retention to be maintained in a pile? e.g. a new pile treated to 2.5 PCF will need to retain 'x' PCF after so many years? Any help pointing me in the right direction is appreciated.
As part of an Arbitration proceeding, an inspector testified that he encountered a field weld on a steel beam at the dwelling in question. From a code persptive, which code governs this type work? (dwelling was contructed under IRC 2000) I assume there must be a requirement to have a P.E...

When constructing cofferdams for 'small' bridge footings we often backfill the void between the concrete footing and temporary steel sheeting with dense graded aggregate (DGA). This allows us to remove the lower tier waler and cross braces. In essence, it provides a continuous brace. When the...
I am investigating the feasibility of installing a rock wall along a cut in highly weathered & fractured shale on a golf course (central/north new jersey). Wall height up to 7' in a localized area, most of the wall is approx. 4'-5'. Question, what is the recommended method of determining active...
Interested in a program that will develope contours. Recently started using Connex software to download data into autocadd. Is there a stand alone program that will use these points to generate contours? Also, Connex will only transfer points with 5 decimal places into autocadd. Connex tech...
When designing a temporary soldier piling/lagging system where rock is encountered below the excavation/dredge line, what are reasonable Kp values, assuming the h-piles are set in augered holes filled with lean concrete? Any reference sources you can suggest? Thanks you.
Any recommendations on publications/reference material addressing CMU retaining walls? Specifically, landscape retaining walls varying from 2' to approximately 6'. Client wishes to install stone facing over the CMUs, therefore segmental block walls (keystone, etc) are not an option.
Looking for info. on grinder pumps for residential applications. Maybe low pressure/small diameter forcemanins? Am performing some cost analysis for a residential development (22 homes) and am looking for options to deep sewers. Any leads?
With varying degrees of increase, allowable bending stress for members in temporary structures (braced excavations, walers, etc.) is common. My question is: is an increase in temporary stress allowable, or common practice when it comes to sheet piling? Any comments would be appreciated.
I have been given the responsibilty of spot checking design plans (specifically temporary sheeting designs). Although the design consultant who prepares these plans has a fairly good track record of internal review before releasing plans, mistakes do happen. My question: Where can I find a...
First off, I am a Civil guy w/minimal survey field experience, so please excuse any mis use of terminology. My question is, can anyone recommend a type of instrument(total station?) that will aid in obtaining and plotting topography over relatively small tracts (less than 10 acres). This will...
Does anyone know of an online source for US Steel's Steel Sheet Piling Design Manual? I believe it was published in 1982. I remember once accessing it through CAL Dot's web site but can't find it. Any help is appreciated.
