I am investigating a house in Central Texas built in 1959 with a slab on expansive clays. Over time the house settled down towards one corner as much as 7 inches. The owner installed hydraulically driven steel piers (Perma Jack system) around the perimeter to stabilize the foundation roughly...
We are planning to core through existing 60" drilled shafts and insert smaller 30" shafts. The original lengths are not long enough. I'm looking for any feedback with this procedure - positive or negative experiences, risk of drill bits breaking, anything at all. We have investigated other...
We are looking at constructing a bridge column foundation consisting of four-48 inch reinf. concrete drilled shafts. Two of the shafts are existing and two are proposed and all four have the same existing/plan lengths based on point bearing.
During excavation of the two proposed shafts, it was...
My Ctrl key is not operating the way it normally does. For example, Ctrl+Home takes me to the start of a row and not the beginning of the worksheet (Cell A1). Also, Ctrl+RtArrow and Ctrl+LtArrow bring me to some odd number of cells to the right/left and not to the last/first column of my data...
A friend of mine owns a house in Virginia. His property is 3-4 feet higher than his neighbors and separated with a 90-foot long cinder block retaining wall. The wall needs replacing and his neighbor won’t pay the additional costs for concrete pavers so they have decided on a pressure-treated...
Hello. I have water on a bridge deck flowing into a gutter and into an 8 inch pipe that runs down the length of a 90 foot column. The pipe has a 90 degree bend at the bottom just before the water expels out of the column.
The water is flowing out too quickly and onto a nearby street. I am...

I have a worksheet that represents employee yearly hours for a project. 12 columns correspond to each month and the rows correspond to each employee.
I have copied this worksheet several times, each worksheet representing a different project. Each project will have the same 12...
I have a set of anchor bolts that are not properly aligned at the top of a column. 8 - 1" x 3'-0" A307 bolts with triple nuts were used and almost all of them are out of plumb. There's no way to fit the base plate over the bolts. The column stands alone so there is plenty of room to maneuver...
I once saw a number of rows that were grouped together. They were connected by a vertical line next to the row numbers and there was a box allowing you to expand (plus sign) or hide (minus sign) the group of rows.
I prefer this much more than right click -> Hide.
Does anyone know how to create...
Given the SCDOT Seismic Specification loading requirement of designing the connection between the superstructure and the substructure for a lateral load equal to 20% of the dead load reaction in the restrained directions, do you apply the lateral load at the interface between the superstructure...
I am looking for a good reference book for MathCAD 2001i Professional. I have found several general MathCAD books at the store but does anyone have a favorite or any suggestions?
Also, does anyone know a good source or website for learning VB Script for MathCAD? Again, tons of general books to...
This is structural in nature but could apply to any subject:
I have set up a set of if statements that will output a rebar diameter based on rebar size. That's no problem.
bar_diameter := |0.375 in if bar_size = 3
|0.500 in if bar_size = 4 (etc.)
However, I have several...
