Types of Plans
Civil Plans
Shop Drawings
Slide4Types Of Plans
What is a blueprint(Plan)?
A blueprint (Not really blue anymore) is a set of drawings that show the overall work to be performed on a project.
Slide5Types Of Plans
Civil Construction Plans
–Roads, parking lots & airport runways that are drawn by a Civil Engineer.
Shop Drawings
–
V
ery well detailed drawings of one piece of the project such as a box culvert.
Slide6Types Of Plans: Civil
Often drawn by civil engineers
which are
engineers
who
design
and
maintain
roads, bridges, dams, and similar structures.
They deal mostly with the earth work & grading,
storm sewer, sanitary sewer, gas lines and other utilities.
Types of projects you see using civil plans are
road projects, airports, parking lots for buildings & residential subdivisions. See the example to the right.
Slide7Types Of Plans: Shop Drawings
Shop drawings are very well detailed versions of something specific on a project like a special manhole or water quality unit.
They
usually show every aspect broken down
into easily discernable information for engineers and plant personnel to use for their respective purposes.
They often range from a
few pages to over 100 pages
long to encompass every specific detail necessary.
Slide8Civil Plans: General Break Down

General Notes
Removal Pages
Plan Legend & Symbols
Utility Pages
Overall Utility Plan
Storm Plan
Sanitary Plan
Water Main Plan
Plan Vs. Profile View Difference
Details & Specifications
Slide9Civil: Cover Page
The cover page has a lot of
vital information
that pertains to the project such as:
Name
of the project
Physical location
of the project for delivery purposes
Specific county/twp
. for the project that may have certain regulations for different aspects of the project
Engineering company
who designed the project
Revision number or approved for constructionWhat type of job is it such as a road project or parking lot
Slide10Civil: General Notes
The general notes page will contain vital information that can pertain to
type of storm pipe used as well as the class of storm pipe used.
It can also contain different notes about the connections to from the pipe to the manholes such as a
grouted connection or a booted connection.
Slide11Civil: Removal Pages (If Any)
Removal pages show what is existing in the ground
per the “as-built” plans from previous projects on that site
They may also show what is to be
left in place and used on the new project
Sometimes having the existing information can help solve issues with the proposed structures
Not all jobs have removal pages
as it could be a completely new site
Slide12Civil: Plan Legend & Symbols
In order to be able to read construction plans, you must first know what to look for.
To the right is a
typical legend that is used to identify manholes, pipe runs, and other utilities
on the project by using symbols to represent what is placed in that location.
As you can see, there are
different line weights & symbols
, or light vs dark, for proposed lines vs existing lines.
The manhole symbol (no sump) is a different symbol than the catch basin symbol (usually 2’ sump).
Sanitary sewer lines are marked with a “s” and a solid line.
Storm sewer lines are marked with the size of pipe and a dashed line.
Water main lines are marked with a solid line and a “w”.
Every engineer does it differently but uses similar symbols to differentiate between each of the utilities; this is just an example of one of them.
Slide13Civil: Utility Pages – Overall Utility Plan
The overall utility plan can be quite confusing with all of the different lines and line types.
Using the legend can help decipher which lines are which.
Sometimes just picking one manhole and tracing the lines will help you identify what system it’s apart of whether it be sanitary, storm, or water main etc.
Some people like to use different color high-lighter markers to bring out the different utility lines such as storm, sanitary, water, gas etc.
Top photo shows a standard utility plan vs the bottom photo shows each utility highlighted and separated to show clarity.
Yellow is Storm
Green is
S
anitary
Orange is Water
M
ain
Slide14Civil: Storm Plan
The storm plan will show everything specifically related to storm water control
which is rain water collected from parking lots and roof drains etc.
It shows
the length and type of pipe
used between manholes.
Sometimes only the pipe size is listed and you have to search for the pipe type and class that it pertains to in the general specifications or detail pages in the back of the plan set.
Every engineer does it differently and no two plans are alike for the most part.
It shows the necessary information about each manhole as well:
Rim:
Final ground elevation on top of manhole (Top of Casting)
Invert:
Elevation of the inside bottom of pipe entering or exiting the manholeStructure Diameter:
Inside diameter of the manhole
Pipe Size:
12”, 24”, etc.
Direction of Pipe Run:
N, S, E, W, etc.
Type of Manhole:
MH, CB, STC, Pump Station, etc.
Sump:
Usually 2’ of extra manhole depth under the outlet pipe to act as a trap for dirt, sand, and other debris traveling in the storm system.
Slide15Civil: Sanitary Plan
The
sanitary
plan will show everything specifically related to
sanitary sewer which pertains to the flow of human waste products.
It shows the length and type of pipe used between manholes.
It shows the necessary information about each manhole as well:
Rim:
Final ground elevation on top of manhole (Top of Casting)
Invert:
Elevation of the inside bottom of pipe entering or exiting the manhole
Structure Diameter:
Inside diameter of the manhole (Mainly 48” for Sanitary)
Pipe Size:
6
”, 8”,
etc.
Direction of Pipe Run:
N, S, E, W, etc.
Slide16Civil: Water Main Plan
The
water main
plan will show everything specifically related to
water distribution which is the flow of fresh drinking water as well as water for fire control.
It shows
mostly the water main lines but sometimes there are
concrete structures called Gate Valves or Tapping Sleeve Valve in Well.
Most of the time you will only see what type of water main structure it is and the Rim Elevation used.
More details about these structures will be located in the back of the plans.
Slide17Civil: Plan Vs. Profile View Difference
Plan View
(Looking Down From the Sky)
Profile View
(Looking from The Side)
Slide18Civil: Details & Specifications
The details and specifications are usually found in the back of the plan set and have very important information regarding the
special regulations or rules that govern the manholes, pipe, and other product on the job.
One example for sanitary manholes would be if there are any
specialty coatings or admixtures required
based on the existing soil conditions.
They can be anything from
detailed breakdowns of specialty structures
such as an outlet control structure or just the simple requirements for storm and sanitary manholes.
You will also find details on the water main structures on the project if there are any.
See next slide for examples.

Slide50Shop Drawings: RCP Pipe Bend
Pipe bends allow for a change in direction mid run, measured in degrees (°), without using a man hole.
Bends are used when the pipe run needs to be
deflected to avoid some sort of other utility
or structure such as a building foundation for example.
When making the cut line, whether it be wet-cast or dry-cast pipe, the
cut line only measures half of the angle
that the completed bend is supposed to be.
This is because once you rotate the top half 180° into position, the
(2) cut lines then add together
to form the full bend in the piece.
Call it out!:
What is the measurement, in degrees (°), of the completed bend?What size pipe is being used?How many lift holes ar
e there?
What class of pipe is being used?
Slide51Shop Drawings: RCP MH Tee
RCP Manhole Tee’s are used in place of man holes when a long straight run of larger pipe is being installed on a project.
It allows for faster installation time on the job because you don’t need to stop to install the manholes and pipe connections. You can just keep laying pipe.
Can be used for shallow or deep bury conditions by differing the MH risers used on top.
Slide52Shop Drawings: RCP Saddle Tee
RCP Saddle Tee’s are also used in place of man holes when a long straight run of larger pipe is being installed on a project.
It allows for faster installation time on the job because you don’t need to stop to install the manholes and pipe connections. You can just keep laying pipe.
Mainly used for shallow bury projects where you only have enough room for placing the frame & casting on top.
Slide53Shop Drawings: MH Opening Angles
The angles of the pipe entering and exiting the manholes are determined using the circular protractor to the right.
You start by placing the “0” where you want the steps to be, and then read the corresponding angles of where the pipe enter and exit the manhole.
These angles will be the information you use to input into the manhole program such as Titan.
See example on next slide.
Slide54Shop Drawings: MH Opening Angles
By placing the “0” mark at where you want the steps, the corresponding angles are shown for where all of the pipe enter and exit the structure.
The steps are at 0°
The 6” HDPE is at 90°
The 15” RCP is at 140° & 230°
NOTE:
There is a specific angle/distance that needs to be accounted for when placing holes close to the steps. You can only get so close before you are out of specification or drilling right into a step location depending on hole size.
Slide55Shop Drawings:
Hole Size & Clearance
When a pipe is installed into a manhole, the hole that it is being placed into, needs to be large enough to accept the pipe as well as the means to create a water tight connection whether it be grout or a boot
.
Example: 15” ø RCP has an OD (Outer diameter) of 19.5”. With a 24” ø hole to place it into, that leaves 2.25” of space all the way around the pipe to seal it.
If the pipe is being booted, a specific size hole must be used in order for the boot to properly tighten against the manhole, and then against the pipe coming into it.
In the example to the right, there isn’t a booted connection, therefore, the left over space around the pipe will just be grouted in the field.
Slide56Shop Drawings: Specialty – OCS
(Outlet Control Structure)
Outlet control structures restrict the flow of water by placing a concrete wall in the middle of the manhole.
These concrete walls are called weir walls and they contain
specific size holes at specific elevations
that are calculated based on on-site water volumes, detention pond capacities, rain rates, etc.
The weir wall slides into keyways that are cast in place when produced. The joints between the weir wall and manhole are then sealed per the engineers recommendations.
These shop drawings allow engineers, as well as plant personnel, to see the whole structure in it’s entirety.
Every detail is called out so that no question is left unanswered and all parties know what is expected once it is complete.
Call it out!:
What’s the Rim elevation?
What type of pipe is entering and exiting the OCS?
What’s the inner diameter of the structure?
How thick is the integral base?
At what angles are the keyways placed?
What’s the heaviest pick weight?
How much room is there for casting and adjustment?
Slide57Shop Drawings: Specialty – OCS
(Outlet Control Structure)
The weir wall has it’s own specific drawing
because of the amount of detail that is needed in order to show every single aspect of it including it’s size and placement of holes.
Call it out!:
How wide is the weir wall?
How thick is the weir wall?
How tall is the weir wall?
At what height do you place the 4.5”ø holes at?
How many ¾”ø holes are there?
What kind of reinforcing is called out?
Slide58Shop Drawings: Specialty –
Pump Station
Pump stations take incoming storm water or sanitary human waste at a lower elevation via gravity and pump it out at a higher elevation using electrically powered pumps that are placed at the bottom of the structure.
Typical pump stations will have an access hatch in the cover so as to allow for the replacement of the pumps in case they fail or need service.
There is usually a specific location the engineer wants to place the hatch so as to align the pumps on a rail system for easy service as well.
A vent is also typical in the cover as well.
Shop drawings allow you to pin point the exact location of everything that is necessary to build the product.
Call it out!:
What is the size of the inlet pipe entering the manhole? (Tricky…)
What diameter is the oversized base?
What is the offset, in inches, of the outlet pipes from the centerline?
What is the inner diameter of the structure?
What brand of boots are being used for the pipe penetrations?
What is the heaviest lift weight?
Slide59Shop Drawings: Specialty –
Pump Station
The cover for the pump station will have very specific placement of the hatch so as to align with the rail system that the pumps attach to.
In this case, the hatch is centered on the cover from both sides.
Note the placement of the 6” SS vent.
Call it out!:
What is the clear opening of the supplied hatch?
What weight capacity wire rope anchors are being used?
What reinforcement is being used in the bottom mat?
What size bar is the diagonal bar?
Slide60Shop Drawings: Specialty –
Water Quality Unit
Water quality units take the incoming storm water and separates the solids/oils out of the stream and contain it within the unit.
Anything from sand particles, pebbles, oil and gas can be separated out and held within the unit.
This is accomplished by the use of baffles, pipes, and the different properties of the incoming substances that run through a special insert that is installed after the manhole is produced.
The water quality units are typically located before the inlet of an underground detention system or sometimes inline with the discharge pipe for the whole job.
These units will typically need to be cleaned out periodically.
Call it out!:
What model of STC is this?
What is the inner diameter of the structure?
What is the hole size for the inlet pipe?
What specific boot is called out for the outlet pipe?
How thick is the integral base?

What angle are the steps located at?
What diameter is the oil port?
Slide62Shop Drawings: Specialty –
Grease Trap
Grease traps are typically used in sanitary systems to catch the heavy greases and oils that are dumped down the drain at restaurants and other places.
A common project to see these on is a Taco Bell.
They have a baffle wall similar to an outlet control structure that contains the grease/oil in the first compartment and allow the normal liquids to flow through.
These units will typically need to be cleaned out periodically.
Call it out!:
What is the height of the base section?
What is the thickness of the baffle wall?
What is wall thickness of the structure?
What size are the access openings?
What is the capacity of this model on gallons?
Slide63Shop Drawings: Specialty –
Detention System
Detention systems are used to store rain water underneath parking lots and roads so as to not over load the downstream storm drainage system in heavy rainfall events.
In order for the detention system to work, an outlet control structure is used at the outlet end that contains a wall in the middle of the structure with small holes in it that only allows a certain amount of water to exit the system in any given minute.
Using a combination of horizontal pipe tee’s, vertical access tee’s & end plugs, the detention system can be configured in multiple row’s and orientations to allow for different volumes of water necessary for each project.
Call it out!:
What is the size of pipe being used?
How many 48” access tee’s are there?
How many stock pieces of pipe are we supplying?
What is the horizontal distance between the (2) systems (Left & Right)?
