Disagreement is about design approach.

If I disagree with my supervisor and I am the one signing the engineering plans What is the right way to do? What does ethics say? Just do what my supervisor say or confront him.

What are best practices that need to considered for a roadway, storm sewers, water line project that will be designed and constructed in a high water table location? The water table is like 4' below the existing grade. Thanks

I've few questions - Probably somebody can shed some insight What unit will the field survey data be? Feet or Survey Feet? I work in Texas and coordinates are in millions. The field data in my office is processed in autocad and then converted to microstation for design. AutoCAD's feet is used...

Will GF be sufficient? I am concerned if there is an event at the park.

A park with playgrounds (football, soccer, etc..) is being developed adjacent to the street I am designing. An intersection exists 1/4 mile ahead of the entrance to the park.. I am leaning towards a warrant study but my question is the traffic counts is for existing traffic and how would one...

thanx for your suggestion and insight. How expensive is aerobic process cost? bridge and surcharge are cost and schedule prohibitive

Not yet being constructed yet but the engineers has specified the temp shoring. what are the anticipated problem if the temp. shoring is left in place?

It will hold the roadway built in the 1st phase.

My roadway is being constructed in a fill embankment. Construction sequence is proposed to construct half width at a time. Temporary shoring is proposed to protect the embanked roadway (12' higher than existing). While doing the second half how would the required compaction at/near the shoring...

Can anyone share their experience/best practices what are the precautions/test or things to look after, after a rainfall event has occured during roadway construction? for example - rainfall occured while preparing subgrade? Do one need to test for density after rainfall event? 2nd example -...

My concerns is pipe leaking and leading to piping action. In major flood event, the roadway will be shut down. guard rail is specified. No such criteria as how long to drain. will have to hold water until the level in stream come down n release thru flap gates).

yes the flap gates are at the outfall.

Landfill is solid waste and construction waste site. 3' clay cap, closed in 80's per records

Yes, roadway is for public predominately passenger car but truck loads are also anticipated. Design std calls for 20k vpd with 10% truck traffic. c

Does anyone have any experience on designing/constructing roadway on top of landfill area. We are considering an asphalt pavement (8" thick 'no basis') knowing issue of maintenance.

I have a mile long road with ditch on both side. 4 x-culverts are proposed which are tend to act as a balancing resorvoir (max 60" pipe d/s). Will there be any problem since the culverts will be submerged for few days (3-4 days) before the water is finally let go through flap gates. culverts...

froude - community PW decide that the roadway can be inundated. If my project is determined to be 4' under water for 100 yr flood, doesn't that mean my culvert is under water as well and hence overtopping?

I have a existing roadway culvert in zone AE. We are proposing improvement on the roadway (widening) but decided (higher officials) to leave in AE zone. Existing culvert is 2-60" pipes for 2.2k cfs flow at culvert. The 100yr flood elev (HEC-RAS) at the culvert determined is 4' above the pavement...
