deign meetings (Shoring related)
whom should u ask ?, Its always best to take multiple options saving a few thousands by taking a free advice or the cheapest advice may cost u lakhs in the future
reliable if they have experience in soil
they deal with soil on a daily basis, its best to talk to them, since an experienced geotechnical engineer will understand the complexity of soil which is not as easy as steel or concrete
may or may not be reliable
is the design and constrcution being considered in the economics of the entire project?
also, leads to a major waste of time in discussions and redesign of structural aspects which did not take into account shoring systems
usually not, this eventually affects the final money spent on the shoring systems
is the design, and construction of shoring taken into consideration in the schedule?
is the structural design finalized?
constant changes in the structural design
leads to a lot of changes in shoring design
the changes are also mean a time constraint to produce a new design.
unimaginably unnecessary and waste of time
since shoring remains scrap in reality, the change if heavier than the one earlier design may lead to an unhappy client, which puts pressure on the Geotech designer to design a more economical shoring system.
leads to a waste of time and as they say time is money
is shoring required
shoring requirement depends on structural design, soil types, and site surrounding.
ground levels change the total excavation depth so have to be taken into consideration

building on piles
usually doesn't matter but the definition of far away is still determined by checked the slope of the piles

trees: - if not allowed to be removed may affect teh stability of the soil. if the tree is too close to the proximity of the shoring line, a 300 or greater pile diameter cannot be drilled hence the 200 or lower has to be designed for such portions. A 200 dia and lower cannot be designed without an anchor for a excavation depth of greater than 4 which means its an additional cost, also the constructing a 200 dia pile is costlier than any other.
distance between the compound wall and inner wall of shoring wall ( the inner wall of shoring depends on the the space requirement by labors to construct the retaining wall, this distance should also include the future view of requirement of removal of the anchor if placed one)
floor plans, including any offsets
offsets may mean change in the usual path of the shoring line which may lead to change of construction sense and also higher cost.
basement levels (i.e excavation depth including footings)
a thorough study of geotechnical data may help economize the shoring design or in some cases eliminate shoring completely. (In this case the client pays only for the advice given by the geotechnical engineer and not his design which may be worth it)
site visits by the geotechnical engineer
to observe site levels
to observe surrounding area
to observe soil types
a in house geotechnical engineer/structural engineer/contractor could be jointly consulted to decide if the shoring is truly required.
