A project to remediate the site of a former manufactured gas plant in Norwich, New York, has
seen the in situ solidification of more than 52,000 cu yd of contaminated sand and
gravel. The work also involves the recovery of non-aqueous-phase liquids and in situ
chemical oxidation of nearby contamination.

architectural expression on a grand scale, the
Al Hamra Firdous Tower, in Kuwait City, boasts
a structural system and exterior form developed
symbiotically as the building’s geometry was
created by a spiral slice of a prismatic volume.
