have to get this off my conscience and air this question.
If you played with Playdough before, you'll likely understand.
This is a 3d image of the proposed foundation underpinnings for Thurgood Marshall Middle School.
The newspaper stated once the soil is fully or partially clay substrate, therefore requiring 150' pile underpinnings.
This image drawn by the architects shows the underpinnings in brown… but they are not drawn 150' deep (to not scare the viewers?.. or is based on unknown data the bedrock is higher or actually lower than 150'? ) The scale of the piles appears to be drawn at around 10-15' deep… so multiply the height by 10+ (more to understand how deep these piles will be in the ground)
Notice the proximity of the rails hidden by some leafy green.
Astonished yet? I'm beyond trying to reason this as an efficient design.
To get to the dramatic question.
What happens to clay substrata when pounding hundreds of piles at x amount of depth into the earth? Playdough teaches children, the clay swells and shifts. Will the earth shift around this construction site?
I am not an geotechnical expert but would like to raise caution to surrounding homeowners and business owners to keep an eye on their foundations for shifting during construction and to report issues asap. This can and has occurred in other areas.
The utmost concern is that the rails too may shift.
Precedent events tell there have been several train derailments around the globe when the earth's crust shifted. If you don't believe me, read it hear…http://www.examiner.com/article/is-an-epidemic-of-train-derailments-2-week-period-coincidence-hardly
I would raise caution to the MBTA, to keep an eye on the rails during and after construction so we do not see a train derail here.
If you think the chances are slim to none, then ignore this because it probably will not affect you. If you live or work here, please just be aware what is occurring with every pile drive in the ground.
If you are a leader, please start ask questions.
In my humble opinion, this foundation is an inefficient waste of taxpayer dollars. Better sites could have been studied
