Some of the more "interesting" projects are demolition engineering.  Husky Stadium Roof for example:

The eastbound ramp of SR90, a curved post tensioned box girder over the westbound ramp, Royal Brougham Way and 3rd Ave South was a real staging and shoring challenge:

Sectional Barges provided temporary support of the Norman Bridge during demolition:

The Monroe Bridge was ready to go without our help:

Of course we design new structures too.  Here's our Bullfrog Bridge (195' span steel truss) being launched into place:

We do a lot of work with contractors on steel and precast concrete erection engineering.  Here's the south runway truss of SAFECO Field being positioned for it's pick:

Here's the Seattle Seahawk Stadium arch going up:

Then there are the really unusual projects.  Here's what are 750 Ton Capacity "Friction Brackets", used to support the SR5 Ship Canal Bridge during it's Seismic Retrofit look like:

On a somewhat more "19th Century" side of the spectrum, here's a look down at the Ultra High Molecular Weight Polyethelene Stave Pipe (banded with stainless steel bands) designed to bypass a manhole which couldn't be removed due to costly arts improvements that had been made at the surface around the manhole:

Here's an shot of the Lower Baker Lake, Fish Collector, Net Transition Structure, Assembly frame/transporter we designed for SKANSKA USA:


Here's a look at a sheet sheet pile cofferdam we used to keep Elliot Bay (Puget Sound) out of our 53rd Ave Pump Station Addition excavation:

Here's a load test we provided for a remote "railroad car" bridge:
