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...
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...
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 -...
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...
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...
For a 45 mph posted speed limit, what would be the acceleration length? It is in urban area and the curb radius is 35'. As per AASHTO exhibit 10-70, the length i'm coming up is around 600'? It appears too long? Please help me with any suggestion or refrence.
Thanks
I have a 60 Ac project site with multiple basins, site laid out by architect which I have to abide by. My city requires using unit hydrograph method to size basins and store only incremental runoff. Is it Ok to compute the incremental runoff volume for the whole site and size the basins based on...
How do I restrict flow only on the main channel for low flow condition without a leeve? It seems "Bank" is used just for "n" value. Shouldn't the bank station recieve any flow if the main channel overtops? Please help
