DATES COVERED: June 11, 2013
PROJECT: Agylix— Equipment Installation
ADDRESS: 7904 SW Hunziker St—Tigard, OR
INSPECTOR: N.Shannon—CWI#98060018,ACI#00952896, ICC#0887203-B5/-10/-891-491-861-841-601-831-S1/-S2,OBOA#321
06/11/13 - Structural Steel Field
As requested, CTI representative was on site and met with Plant Manager Steve Anderson. At the direction of the
Structural Engineer, Bill Ness of Evergreen Engineering, Carlson Testing was asked to evaluate the construction of
personnel and equipment platforms provided for the equipment. No design plans were available for review and the
structure was painted. The Engineer of Record has asked us to provide a review of the as-built conditions for his
consideration and determination if additional work is required to expose the work for inspection.
Observation Platform (west side equipment platform)
The observation platform consisted of grey, painted structural box tube, channel and angle iron shapes. In most
cases components were fully welded and weld appearance was good. Platform legs and stairs were securely
anchored to the concrete. High strength (A325) bolts were used to anchor the primary structural steel; no match
marking was noted so a snug tight condition is assumed. Standard A307 machine bolts were in place for the hand
rails and stairs. Areas of note during this plafform inspection were as follows:
• NE post of observation platform (next to north stair) (see photo #1). One anchor bolt could not be installed due
to edge of concrete. A separate plate has been added and contractor reports that the intension was to weld the
plate. It has not been welded yet.
• South frame mounted to platform for electrical racking (see photo#2). High strength bolts are used to anchor to
the perimeter channel however wedge washers have not been installed to adjust for the sloped surface.
• Supporting frame for expanded metal floor(below and to the west of the electrical rack noted above (see photos
3, 4 and 5) Significantly less weld support this frame than other areas. Typical has bottom leg welded top and
bottom plus added weld on the vertical. This location has weld top side of channel leg only.
• Supporting frame for expanded metal floor (north side of observation platform - see photo 6). No support has
been provided along the edge of the equipment panel. Contractor reports that it is the intent to install some
supporting structure below.
At the east side equipment platforms it was noted that the platforms have been assembled using SAE grade 6 bolts
instead of A325 bolts. Again, no match marking was observed, snug tight condition is assumed. Areas of note
during this plafform inspection were as follows:
• At the high (north) platform there is a bump out on the west side for ladder access - see photos 7 & 8). The
horizontal channels supporting the platform have been welded one side only on the exterior vertical surface.
Engineering review is suggested.

The remaining portions of the platforms,, ladders and guard rails appeared complete and of general good
workmanship but, again, no permit or plans were available for review. This inspector is no able to address issues of
member size or placement requirements. If conformation of member size and locations are required please provide
design drawings for comparison.
Prior to departure these inspection observations were shared with Steve Anderson and a sub-contractor providing
the installation.
***CHECK ONE BOX ONLY*" YES NO
1. This is a preliminary inspection only. —OR—
2. The work inspected conforms to acceptance criteria listed above. If"No,"the portions of the work that
are non-conforming items are clearly s tated above and will be added to the NCL. Remaining portions ❑ ❑
of the work,which are not preliminary in nature,are to be considered as conforming.
