Hi Everyone, I'm working on a national park project in California. Its open space. In reviewing its location, the areas around it are designated as high fire hazard zone but my project site itself is designated as federal fire hazard responsibility. My question for those of you that have...

Hi Everyone, I received a sewer flow rate in DFUs and gpm from a plumbing engineer for a project site that has office and a maintenance shop. For now assuming 8 hr work day. However the ahj is interested in a gallons per day rate. What's the conversion factor? I'm assuming peaking factors are...

Hi Everyone, I've searched if there were similar posts with my question but couldn't finding anything specific, other than on a thread that was closed so here it goes. When it comes to thrust block sizing, NFPA 24 calculation methodology includes a Factor of in their equation and at least NFPA...

All, I'm looking for a calculator that is easily accessible that I can use to back calculate the adequacy of a concrete section. Basically I'm encountering the need to show whether a 4" Concrete Over 12" Aggregate Base will hold an occasional 22,000 lbs axle load. Long while ago, I used to use...

Has anyone ever sized a rainchain for flow? I have a project where client is considering instead of your traditional downspouts. I've seen them on projects but I don't recall been involved in the sizing. With so many factors (due to the so many choices in style and configuration), my initial...

All, Its been a while for me but for fire flows in the past I was used to receiving my static pressure, flow and residual pressure. I would then either graphically or mathematically would utilize these numbers to predict how the system performed to say either at minimum pressure of 25 or 20 psi...

Need help. I'm looking for the building code reference, either CBC, IBC or both from what I recall the requirement for grade outside the building to be a certain height from finish floor. I recall its 6 inches if the finish grade outside is concrete and 8 inches if its dirt. Can someone point me...

Looking for guidance on this one. I'm relatively new to practicing engineering in Texas. I have a parking lot project where there are a couple of handicapped parking stalls. Through my previous engagement, I'm used to seeing the International Symbol of Accessibility painted on the pavement in...

Modeling question: The ahj has a minimum Tc = 5 minutes requirement. The available rainfall data for the project site has IDF curves for a series of storms with a minimum duration of 10 minutes and higher. Have you encountered such a scenario? It would appear to me that I don't necessarily need...

Does anyone have a good reference point to find standards dimensions and turning specs for a Type 1 Fire truck? Its my understanding that this type of truck appears to be used in wild land/open space fire events.

Hey Everyone, I'm working on a project in Panama and looking to see where I could get rainfall data for the area of my project. Trying to develop IDF curves for hydrology and hydrailc analysis. Any suggestion of where this information can be obtained? I will also be working on other projects in...

Hello Everyone, I wanted to check in with all of you to see of any good resources, literature for installation of water lines in hill situations. I'm installing an 8 inch fire water line on a hill with quite steep slopes maxing out between 20 and 25%. Any information on anchor block design and...

Is anyone outer familiar with potable technology that will help remove Selenium out of water? Thanks.

Any suggestions on pavement reference manuals? Both rigid and flexible pavement? AASHTO, FHWA? Where would I go for industry standards?

I wanted to get some input on general cost of earthwork. While the unit cost per cubuc yard varies by different factors such as gepgraphic location, complexity of earthwork involved, total earthwork, and remediation measures as needed to name a few, what unit cost would any of you have across...

Section B105 states the required fire flow for buildings. B105.1 for one and two family dwellingswith fire flow area that does not exceed 3600 sq ft is 1000 gpm The Exception calls out for 50% reduction as approved when the building is equipped with a sprinkler system. Table B105.1 calls out...

Hello Everyone, Hoping to get some help with this modeling issue, Background: In a previous company I was using StormNet by Boss Int for hydrology and hydraulics modeling. (I also have experience with other software) This was a few years back. I started with a new company just over a year ago...

Hello All, I have an elevated pad (5 ft max at high end) with a perimeter retaining wall where temporary buildings will be installed. Eventually these buildings will be removed and the pad will be used as a parking lot. In areas where the grade differential exceeds 30" I am definitely installing...

Hello All, Would anyone point me to a link or a site that may contain standard language that should be included when approving product submittals, shop drawing submittals and others? Let me know if more clarification is needed. Thanks in advance.

Hello Everyone, I am working on approximating water demands for a future laboratory facility. This is all at the planning level but wonder if anyone outer is aware of any literature that can give me a starting point. Anything with daily unit demands per square foot would be very helpful and...
