Hello, Site Civil Here. there is always a rub when groundwater is a challenge on a site when localized/perched under a building footprint. Our scope ends 5' outside of the foundation and apparently our insurance will not support us going out of our expertise. Without fail, if gw is found, the...
One surveyor finds control and brings it to a site, sets benchmarks for that site. civil site plans are designed and construction of a building starts.
a second surveyor finds control from a different source and brings it to a site, sets bench marks. civil road plans are designed immediately...
I have been challenged to determine how a vehicle overhang affects ADA compliance in front of a parking stall. ADA standards 502.7 mentions "relationships to accessible routes" and says to use wheel stops as an effective way to prevent vehicle overhangs from reducing the clear width of...
what is your take on how to scope drainage within a closed courtyard? This is always a scoping challenge with the developer on who handles this. from a civil standpoint the risk involved is that you design the drainage space including the surface area and roof drainage that may collect there...
We are now using the internal HGL modeling within civil 3d 2020. The infrastructure engineer that is responsible for designing the roads surrounding our infill project is using Bentley Stormwater Modeling and Analysis Solution.
Our 25 yr HGL using civil 3d is way above the road surface but...
Looking at a 6 acre 50-60 unit multi fam site that once had city right of way frontage. Years back the construction of an interstate bisected that road the parcel fronts so it became a 575' 2 lane road to a dead end and was essentially retained as right of way but closed to public use. we are...
City of Columbia Code requires a standalone interceptor for pool backwash before it hits the Sanitary Sewer. This is a first for me. Anyone else know of an AHJ requiring this? thanks
we have a 6" back flow DCDA serving a single private fire hydrant. Will be installed above ground in an enclosure typically called a "hotbox".
question:
When do you need a heater? Is there a geographical way to determine when its not necessary? We're in SC and it does freeze a couple dozen...
What is the going rate for survey in the South? It appears that folks are overly busy and are all charging 2 times what they were just a few years ago. what are you seeing out there per acre?
Not a flat lander typically, but i have a coastal job with seasonal high water table. the site is farmland with a couple "sumps" where water infiltrates. Large storms accumulate and discharge to a right of way ditch. the design will create two interconnected ponds and the lower pond will...
I have a rail spur on a project that is in Norfolk Southern's jurisdiction and they require HDPE in their black design manual. I don't use HPDE in large diameter often. I'm reaching out to see if anyone knows of a concrete headwall detail for this scenario? I would prefer using a double...
I have a project where the one story building is in the shape of a "C". i have to pad out the full expansion plan in which the facility expands and becomes an "O" in the future and a courtyard is formed. what guidance do y'all have for designing the storm line that will eventually be covered...
I have a unique project where we are designing ramps for vehicle testing purposes. The steepest is 30% for a length of 50' and a width of 12'. A contractor has mentioned issues with paving at that grade. What are the typical limits of asphalt paving machines? Is the constraint also in the dump...
