Flooded Bldg.

[StrP88]

I been asked to help to resolve the bldg. was seeing 2" water on floor
Where shall I start?
What needs to be done?

Some useful info:
One story metal building used as office, locker room, electric room in CT plant.
Floor is ceramic tile.
a swale/ditch goes by plant/bldg that gets overflowed and is not engineered .
around the building was paved with concrete slab recently without proper drainage - what should I check and how I correct drainage and slope for it?
Down spots discharge may also go to bldg I don't know right location for them?

Please tell things I have to check, calculations need to be done? what and where I start to solve the problem?

Thanks

Is their 2" of water on the floor constantly or just after a heavy rainfall event?

First thing you need is a topo survey of the land around the building and the finished floor level. Is land from above or around the site overland flowing through your site? If so you should do a catchment assessment of whats draining to your site and into the swale.

You will need to know the levels, pipe sizes etc of the exiting drainage. This may be shown on the plans, if not you will have to get a utility survey done to confirm it all. You will also need to look at flood maps to see if the building is located in a flood plain.

That is just a starting point.

EireChch (Geotechnical),
Thank you for your response and direction.
Your question on,"Is land from above or around the site overland flowing through your site? " I don't know so where shall I dig for answer to this question?
"Catchment assessment" what is it? What businesses do this for us?
Again thank you for great direction. I appreciate it.

Regards,

You need to know the topography or lie of the land around your site. If your site is at a low spot it may be prone to flooding. Google earth may give you information on the topography (this will be very rough). A walk over of the site will tell you a lot more. Catchment assessment is when know the amount of land that directs storm flows to your site. You work out the time of concentration etc and this will tell you the discharge rate of storm flows. A simple google search will explain a lot for your.

Any civil and or environmental engineering consultancy should do it.
