Hi Everyone,
I'm looking at designing a fully buried wet well for a pump station, inside dimensions are 30' Long x 8' Wide x 27' Deep. The geotechnical report indicates that bedrock is pretty shallow in the area so the well will need to be keyed in. The problem is, that we are also next to a...
I am currently working on a project that requires a partial height removal of a CMU Wall for a building addition. A steel beam header will be installed to pick up the loads from the remaining portion of the CMU wall above. If the steel beam is only grouted to the underside of the CMU wall with...
Hello All,
I have a contractor who has requested a change to the approved pouring sequence specified in the bridge plans in an effort to save time.
The bridge is a three span continuous spread box beam superstructure with a PennDOT Skew of 83° (7° AASHTO Skew). All three spans are 100 feet...

Does anybody happen to have a good example of bridge expansion joint movement calculations that include the beam end rotation as well as thermal movements?
Hi All,
Our company recently received a submittal for a segmental retaining wall, that will be approximately 10-12 feet in height. Typically these submittals are pretty straight forward. However, the design engineer decided to rotate the entire wall, including the foundation base, 5 degrees...

Hi All,
I am currently designing CMU partition walls (non-load bearing) that are 16' high, for an existing building in Puerto Rico. The architect has proposed a steel support frame for behind the walls to provide bracing at mid-height and the top of the walls, see attached image. The length of...
