THORNTON TOMASETTI last week drastically cut the number of volunteer engineers working around the clock at the World Trade Center (WTC) site.
At one point as many as 32 volunteer engineers had been working at the site following the terrorist attack on the twin WTC towers on September 11. The number has since been cut to eight.
Under the revised regime, eight teams of four engineers working day and night have been cut to four teams of two, working mostly during the day.
Arup Americas principal David Scott - who has worked regular shifts on the site since the attack - said that there is less for engineers to do because the structural stability of the site has been largely secured.
Much of the work to inspect damaged buildings - finding placements for massive load bearing cranes on damaged slabs, and tying back lumps of debris protruding from the sides of buildings - is complete, he said (NCE 27 September).
The four contractors clearing away the debris - AMEC, Bovis Lendlease, Turner and Tishman - are also much better organised, he added.
'There is much better understanding and organisation on site and we only really need to think through the problems during the day now, ' said Scott.
The cut in engineers comes from the 170 structural engineers mobilised in the aftermath of the attack that destroyed seven buildings.
They were co-ordinated by the Structural Engineering Association of New York, helping consultant Thornton Tomasetti.
