I have several hundred feet of paved ditch to install, and would like to benefit from the experiences of those who have installed paved deitches. The ditch bottoms range for 2 to 10 meters in width, and the sides slope are 3,4, and 10 to 1, no transitions are necessary. The slab thickness is...
I am in the planning process to remediate an abandoned coal fired power plant site. Does anyone have any experience they would like to pass along on what to watch for, and what, if anything is salvageable and may offset the remediation cost? There are a number of large holding tanks that I...

Looking for a few opinions. I am building a pylon, with reinforcing steel, predominantly bundled bars, ranging from No. 9 to No. 14. With the exception of the No. 14 bars, I would like to lap, instead of mechanically coupling, the reinforcing steel. Some have advised me that the laps must be...
What does dynamic pile testing involve? What does it take to get certified to do the testing? I do a fair amount of work in Phio, and the DOT has come up with a need to test each different group (length, capacity, size, etc.). The suggested reason is to save on pile length, but my experience...
Does anyone have a mass concrete spread sheet they would like to share? I have several mass concrete pours to make in the comming months, and would like to go through a few calculations to determine what R value, for insulation blankets, is needed to help control the specified temperature...
I have a set of plans that require lap splicing No. 18 bars. I have apprised the Owner that it is not allowed by code, however he commented that a professional engineered developed the detail, and he is satisfied that the lap splice is sufficient. Should I contest the issue any further? What...

I am sure there are quite a few factors which contribute to the descision to use or not use an Integral Abutment. But I would like to know the longest contributing span length which would still allow the use of an integral abutment. I am aware that many owners have there own criteria, such as...
I have a very complex, using conventional forming methods, cable stayed tower cap to form, and would like to have the majority of the complexity eliminated by having a steel frame fabricated to establish the geometry, block-ouits, etc.. Does anyone have a vendor, experience, comment, that they...

Has anyone come across a guide, ie. table, software, spreadsheet, that compares a steel beam, and its span length and spacing, to a precast prestressed concrete beam, or vice versa?
Does anyone know of, or have, some material that takes you trhough a step by step input of structure information, to determine a BARS Rating. I have the program, and manual, but there are no pratical instructions on using the program.
