Pons & Associates, LLC

From invitation: Fernando Pons, P.E., will be in the office for a
lunch and learn to present "Managing Underground Risk in Urban
Settings and Greater Washington, DC". Please respond if you would
like to attend.
Projects in urban or developed settings face unique and substantial
risks such as groundwater control, claims from abutters,
underground-related change orders, underpinning of adjacent historical
structures, heterogeneous historic fills, disposal costs of
contaminated media, and other unanticipated man-made and natural
geological conditions. Please refer to the attached document for more
information.
Pons & Associates will provide a certificate for 1 hr. of professional
development.
Thank you.

Notes:
-Acidic soils can corrode metal or concrete pipe.
-Consider thorough env study in bridging docs when doing des/build.
-Phase 1 ESA's are a wealth of historical info about sites.
-Include in early negotiations if you are dealing with a contaminated
site: All the usuals (owner, architect, construction team if known),
AND Insurance providers, attorneys, regulators/inspectors.
-A Geotech Baseline Report can be used as a part of the Contract
Documents. More accurate bids, because they quantify things like cubic
yds of contaminated soils. Use unit pricing to allow for adjustments.
-Karl Terzaghi, father of modern geotechnical engineering.
"Unfortunately, soils are made by nature and not by man and the
products of nature are always complex..." First International
Conference on Soil Mechanics and Foundation Engineering, 19 June 1936

My question: How developed does a concept or design need to be before
env & geotech studies should begin? And conversely, how long is too
late?
Fernando's answer: Right before or during Programming (conceptual)
phase, or schematic design at the latest.

Fibrwrap lunch and learn

Today's lunch & learn in our office was about Fibrwrap -- It's like a fiberglass (but carbon fiber) cloth they wrap around columns or bridge beams that need to be reinforced, and they add liquid epoxy. They can fix bridges and buildings a lot cheaper for structural upgrades or to meet current requirements for seismic forces. A little like bondo for buildings...lol...but carbon fiber like NASA uses for repairs. And they can do a clear version for historic repairs, like on sensitive masonry, or wood timbers or piers.
