Water Distribution Plan & Profile 1

[RHOeng]

What is everyone's thoughts on what information should go in the plan view and what should go in the profile. I'm talking about calling out bends, tapping valves, fire hydrants, joint restraint, concrete anchors,etc. I've always put in the plan view what was visible in the plan view and put in the profile what was visible in the profile. Some jurisdictions require the same information in both places which seems to me to be confusing when there are bends that can be seen in the profile but not in the plan view.

Qouting myself:

"If you want to guarantee conflicts between plans and specifications, or between different sheets of the plans, then, by all means , repeat dimensions, notes details and other elements !

At first, we may think that repeating things will help to clarify them and emphasize their importance. But there is a trap here which is all too easy to fall into. Consider this common scenario. You are preparing plans for a retaining wall which is to be 10 feet in height. There are several sheets to the plan set and the wall appears on three of them. Each time the wall is shown you dimension and label it using the 10 foot design height. Late in the design process, when deadlines loom and conditions are at their most hectic, you discover that the wall needs to be 12 feet high. So you hastily redesign and change the plans accordingly. But you overlook one of the three sheets ! Now you have created a conflict. Sheet 5 does not agree with sheet 7. Your contractor doesn't know which is correct and you now have the additional duty to correct this error and possibly issue a change order for increased costs. As you know, these are never a welcome sight to your client or employer."

good luck

The best rule here is to say it once and say it correctly. Don't repeat things if you don't have to. Changes always occur and small oversights like this can and will happen.

The only reason I see for drawing profiles for water distribution pipes is to identify crossing conflicts, washouts and air valves (you may not have these on a distribution pipe.

I agree with RWF7437 – as far as possible only show information once.

Over recent years I see the majority of profiles drawn in straight lines with pipe gradients shown. The pipe is flexibly jointed and what the designer really wants is the pipe laid to smooth vertical curves with the minimum amount of deflection on each joint. What he doesn't want is what he has drawn i.e all of the joint deflection pulled at one joint at the apex or the valley. So why are we drawing profiles that do not reflect what we want the contractor to build ?

Flummoxed !!
