The first requirement in constructing a edifice project is to sympathize architectural drawings, which are as well called blueprints, or plans. If you want to know how to read these drawings and sympathise exactly what they hateful, merely follow these steps.

1. 1

   Read the comprehend canvass. This volition contain the projection proper name, the architect's name, address, and contact information, the project location, and the engagement. This page is very similar to the cover of a volume. Many cover sheets will as well include a drawing of the finished product, showing yous what the house volition look similar after it is constructed and landscaped.^[ane]

2. 2

   Read the plan index. These pages volition include an index of plan sheets, and sometimes their contents. It likewise will include an abbreviation key, a scale bar with the plan scale indicated, and occasionally blueprint notes.

3. 3

   Read the location programme. This will have an surface area map, with an enlarged location map, ordinarily giving enough information to locate the project site from nearby towns or highways. This sail is not found in all sets of plans.

4. iv

   Read the site plans. These pages usually are numbered starting with a "C", such every bit Canvas "C 001", "C 002," and and so on. The site plans will contain several sheets which testify the post-obit data:

   • Topographical data. This volition provide the builder with information regarding the topography, or the slopes or flatness, of the site.
   • The demolition plan. This sheet (or sheets) will show the structures or features which will exist demolished on the site prior to grading for construction. The items which will not be demolished, such as copse, will exist noted in the keynotes.
   • The site utility plans. These sheets will point the location of existing undercover utilities, and so that they can be protected during excavation and structure.

1. i

   Know that yous should never scale a drawing. If you cannot locate annihilation on the drawing with the dimensions given, get more dimensions from the Architect.

2. 2

   Sympathise the architectural sheets. These sheets will unremarkably be numbered "A", such as "A 001", or A1-Ten, A2-10, A3-X and and so along. These sheets volition describe and give measurements for the floor plans, elevations, edifice sections, wall sections and other oriented views of the building design. These sheets are broken up into many parts that brand up the construction document that yous will need to understand. The parts you'll need to know are described in the steps below.

3. iii

   Read the flooring plans. These sheets volition prove the location of the walls of the edifice, and identify components like doors, windows, bathrooms, and other elements. At that place will be dimensions noted as distances betwixt, or from middle to middle of walls, width of openings for windows and doors, and changes in floor elevations, if the floor is multilevel.

   • Floor plans consist of various levels of particular depending on the phase of the projection. At stage D (planning) drawings may show only the major features of the infinite.
   • At a tender stage, drawings will be more detailed, illustrating all features of the infinite at a larger scale to let a contractor to toll the job.

4. 4

   Read the ceiling plans. Hither, the builder will show the types, heights, and other feature of ceilings in different locations in the edifice. Ceiling plans may or may not be depicted for residential design projects.

5. 5

   Read the roof framing plan. These pages will indicate the layout for joists, rafters, trusses, bar joists, or other roof framing members, likewise as decking and roofing details.

6. vi

   Read the stop schedule. This is ordinarily a table listing the different finishes in each individual room. Information technology should list paint colors for each wall, flooring type and color, ceiling elevation, type, and colour, wall base, and other notes and details for amalgam the finish in areas listed.

7. 7

   Read the door/window schedule. This table will have a list of doors, describing the opening, "hand" of doors, window information (often keyed off of the floor plan, example, window or door type "A", "B", etc.). It may also include installation details (cuts) for flashings, attachment methods, and hardware specifications. There may besides be a divide schedule for window and door finishes (although not all projects practice). A window example would be "Mill finish, aluminum", a door might be "Oak, natural finish".

8. 8

   Read the remaining details. This may include bathroom fixture layouts, casework (cabinets), closet accessories, and other elements not specifically noted on other sheets. Such as, but not limited to: concrete details, door and window details, roofing & flashing details, wall details, door details, deck to wall details and others. Every project is unlike and may or may non include what other projects accept. The Level Of Detail (LOD) is determined past each Architect for each projection. The growing trend is for Architects to have more than, rather than less particular, because the Contractors then have less guesswork and tin more than easily sympathize what to include and what to price. Some builders may or may not have comments about the LOD, simply that has no relevance to what the licensed Architect who is designing the project feels is necessary to properly explain the design.

9. 9

   Read the elevations. These are views from the outside, indicating the material used in exterior walls, (brick, stucco, vinyl, etc), the location of windows and doors from a side view, the roof slopes, and other elements visible from the exterior.

1. 1

   Read the structural plans. The structural plans ordinarily are numbered get-go with "S", as in "S 001" These plans include reinforcement, foundations, slab thicknesses, and framing materials (lumber, concrete pilasters, structural steel, concrete block, etc). Hither are the different aspects of the structural plans that you will need to read:

   • The foundation program. This sheet will show the size, thickness, and elevation of footings (footers), with notes regarding the placement of reinforcing confined (rebar). Information technology will notation locations for ballast bolts or weld plate embeds for structural steel, and other elements.
     • A basis schedule is frequently shown on the outset sheet of structural notes, as well equally notes regarding the reinforcing requirements, concrete break forcefulness requirements, and other written statements for structural strengths, and testing requirements.
   • The framing plan. This will indicate the material used for framing the building. This may include wood or metal studs, concrete masonry units, or structural steel.
   • The intermediate structural framing plans. These are used for multistory construction, where each level may require back up columns, beams, joists, decking, and other elements.

2. 2

   Read the plumbing plan. Plumbing cartoon pages are numbered beginning with "P". These sheets volition show the location and type of plumbing incorporated in the building. Note: oft, home design documents do not include plumbing plans. Hither are the parts of the plumbing programme that you will demand to read:

   • The plumbing rough-in. This sheet will show the location of pipes which are to be "stubbed upward" to connect the plumbing fixtures to water supply, drain/waste, and vent systems. This is rarely incorporated into a residential set of documents, such as for a single family residence.
   • The plumbing floor plan. This sheet will show the location and blazon of plumbing fixtures, too as the road pipes will be run (overhead or through walls) for drinkable water and drain, waste product, and vents. These plans are included although most architects (for unmarried family unit homes) already bespeak the location of the fitting on their floor plans.

3. three

   Read mechanical drawings. Mechanical pages are numbered beginning with "1000". This canvas or sheets will show the location of HVAC (heating, ventilation, and air conditioning) equipment, duct work, and refrigerant piping, as well every bit command wiring. This is rarely indicated for single family unit homes.

4. 4

   Read the electric plan. The electric drawings are numbered starting time with "E". This canvass (sheets) shows the location of the electrical circuits, console boxes, and fixtures throughout the building, too every bit switchgears, subpanels, and transformers, if incorporated in the edifice.

   • Special pages found in the electrical plan pages may be "riser" details, showing the configuration of ability supply wiring, panel schedules, identifying specific breaker amperages and circuits, and notes regarding types and gauges of wires and conduit sizes.
   • Some of this information may or may not be included in single family unit domicile documents.

5. 5

   Read the environmental plans. These are also known as BMP (Best Management Practices) drawings. This sheet will indicate protected areas of the site, erosion control plans, and methods for preventing environmental damage during construction. In that location may be details in the BMP drawings showing tree protection techniques, silt fence installation requirements, and temporary storm water drainage measures.

   • The requirement for a BMP programme originates under the ecology protection department of your local, land, or national governing authorisation. This may not exist required, depending on the Authority Having Jurisdiction for unmarried family homes.

6. 6

   Know that all plumbing, electric, and mechanical drawings are diagrams. Dimensions are rarely given and it is the responsibility of the builder to coordinate the placement of the utility so as to adapt with the building code and the Architectural drawings. Be certain plumbing is located so that it matches up with the desired location of plumbing fixtures. Same goes for electrical wiring for ability outlets and lite fixtures.

   Learn how to lay out a building footprint from architectural plans. To exercise this, you will accept to locate the element of construction you are reviewing to implement a portion of your work. If you are laying out the location of the edifice, you will first await at the site plan for location of existing buildings, structures, or property lines so yous take a reference signal to begin measuring to your edifice footprint. Some plans simply give a coordinate filigree position using northings and eastings, and you will need a "total station" surveyor'southward transit to locate these points. Here is what yous'll demand to practice to lay out a building footprint from the plans:

   • Lay out your building on the site past either the to a higher place referenced program or the measurements given on the site program. Measure out to locations, preferably corners, on 1 side of the edifice, and cheque for whatever "checkpoints" to verify the accuracy of your layout. If you cannot absolutely institute an exact building line, you may have to suppose the location is correct and continue. This is widely accepted in cases where the site is very big, allowing for tolerance, but on a crowded lot or site, the location must be exact.
   • Found the elevation you will work from. This may be a height relative to a nearby roadway, or an elevation adamant from ocean level. Your site plan or architectural floor program should have a bench mark(a bench mark refers to some item, such every bit a manhole lid or survey waypoint with a known elevation) superlative or a "height to a higher place existing form" as a starting point.
   • Utilize your plan to measure the location of each corner of the building, including offsets. Recall what exact element of construction you are using for your layout. You may mark an outside wall line, a foundation line, or a column line, depending on the type of structure and the most applied chemical element for making subsequent measurements.
     • For instance, if you lot are building a structural steel edifice with I-axle columns which crave setting anchor bolts to secure them, you may brainstorm your building layout with the centerline of these columns, where if you are building a wood-framed residential structure with a monolithic slab floor, the edge of the slab would be your all-time choice for the initial layout.

2. 2

   Reference the clarification of various sheets to find an chemical element of structure you are going to utilise in the work you will perform. Plumbers apply the Architect's floor program to locate walls so the pipes they stub up will be concealed inside the wall cavity when the edifice is constructed, then utilize their plumbing floor program to find out what types and sizes of pipes are required to service a particular fixture.

3. 3

   Utilise the dimension scale where measurements are not provided. Equally a rule, architectural plans are drawn to a "scale". An example would be, ane inch (ii.5 cm) equals 10 feet (3 thou) (ane"=10'), then measuring between to walls on the plan sail means for each inch, the distance is 10 anxiety (3.0 m). A scale rule volition brand this much easier, but be conscientious to match the rule scale to the plan's calibration. Architects ofttimes use a scale of fractions, such as a 1/32 calibration, engineers usually use an inch per human foot scale. Some plans or details are not to scale, and should exist marked "(NTS)".

4. 4

   Read all the notes on a folio. Often a particular chemical element has special considerations which are more easily described verbally than drawn, and notes are a tool the builder will use to illustrate them. Yous may see a table of notes on the side of a sheet, with numbers identifying the note location on the plan (a number with a circle, square, or triangle around it) and a respective numbered statement describing the situation on the side of the canvass.

   • Sometimes there may be a single sheet or several sheets of Numbered Drawing Notes that consolidate all or nigh of the drawing notes for an entire set of drawings. Many Architects organize these numbered notes into a CSI (Construction Specifications Constitute) method utilizing i-16 or fifty-fifty more Divisions that categorize the drawing notes into subsections.
   • For instance: a note "4-127" may refer to a type of Masonry, as Sectionalisation 4 represents Masonry. A note 8-2243 may refer to a window or door component, considering Division 8 is Doors & Windows.

5. 5

   Learn to recognize the different types of lines the architects and engineers may use. You should accept a specific keynote tabular array for department of plans, and this will provide information on the abbreviations, symbols, and specific lines used in each section of the plans.

   • An case would be that the electrical plans, a circuit may have the "dwelling run" "leg" (the wire going from the first junction box in a circuit to the panel box (the power source) highlighted or in darker ink than other circuits, and exposed conduits may be indicated past a solid line, and concealed conduits by a dotted or broken line.
   • Because there are many dissimilar line usages indicating different type walls, pipe, wiring, and other features, you volition have to encounter individual program page "key notes" to understand them.

6. 6

   Utilise a Builder'south Calculator to add dimensions when determining distances on your plans. These are calculators which add feet and inches, fractions, or metric measurements. Often, an architect will not requite a measurement to a specific plan item, from a baseline such as the "'OBL" (outside edifice line), and so you lot volition need to be able to add the distances each feature which has a measurement provided, to get the total altitude.

   • An example would be finding the center line of a bathroom wall to locate the potable water pipe stub up. You may take to add together the distance given from the OBL to the living room wall, then the distance to a hallway wall, then across a bedroom, to the bathroom wall in question. This might look like this: (eleven' 5) + (5' 2") + (12' 4")= 28' 11.

7. vii

   Use CAD (Computer Assisted Design) building plans. If you have a fix of architectural plans in an electronic class, as on a CD, you will need a version of the original "cad" program which created it to open up the files. "AutoCAD" is a pop, only very expensive, professional design program, and the designer will usually include a "Viewer" on the disc which you can install on your figurer to view files, so that actual plan pages appear on your screen, but without the full program, you cannot manipulate design components or modify the drawings. Nevertheless, most Architectural firms know how to relieve their CAD and other computerized files as a PDF, which they volition normally e-post to yous and you volition be able to open and view (although not alter, equally the Architects are responsible for the integrity of their work).

8. 8

   Learn how to handle architect'southward plans. These sets of documents are ofttimes very large sheets, near 24" X 36", and full construction sets may include dozens, or hundreds of pages. They are either bound or stapled on the left border, and allowing them to be torn from the bindings, ripped autonomously by mishandling, laid out in the dominicus to fade the ink, or left in the rain can make them hard to use.

   • These documents tin can toll hundreds of dollars (United states) to replace, then try to protect them, and accept a flat, wide, protected piece of work surface to unroll and read them on.

9. 9

   Read the specifications. Specifications are ordinarily printed and kept in a binder, and they list descriptions of methods and materials used in the projection, as well as testing methods, quality command information, geotechnical data, and other data useful in building the project. Still, some Architects practice include the specifications on the drawing sheets (to insure that the specs volition not be misplaced).

   • Specifications are the builder'southward style of indicating the quality standards, materials, model numbers, and other characteristics of projects. Even unmarried family unit homes often have specifications. Specifications are traditionally arranged in numbered sections, typically Division 1-16, although these numbers have expanded considerably during the terminal decade.
   • Many Architects number their paragraphs then that they can cross-reference bodily verbiage from the specifications onto their drawings using the paragraph numbers, which improves the coordination of the various trades.

10. ten

    Wait for notes and symbols referring to "alternate bid items", "Owner Optional Upgrades" and "addenda." These may indicate portions of work which are incorporated in the Architect's drawings, but non necessarily in the architect's contract to construct, supply, or install. "NIC" is an abbreviation for Non In Contract, which ways a certain particular volition be put in a sure place by the owner after the project is finished.

    • "OFCI" or "GFCI" (Owner Furnished, Contractor Installed, or Government Furnished, Contractor Installed) indicate the item is supplied past the customer, but installed by the contractor. Read and understand all abbreviations used in your plans.

11. 11

    Revisions.Architects may event addenda, which are changes fabricated to the documents later they have been released for bidding. Many Architects locate a bare section, frequently in the lower correct corner of their sheets, merely above the sheet number, reserved for a list of Revisions. Revisions are ofttimes numbered and enclosed within a triangle, octagon, circle or other consistent symbol. To the right of each revision number will exist the appointment of the revision, and then to the right of that, a cursory description of the revision. Then on the drawing expanse of the sheet, that numbered symbol will appear in the surface area where the revision was made, frequently along with a "revision cloud", which is usually depicted with a lumpy series of arcs resembled a cartoon deject, encircling the area in which the revisions where fabricated. This allows everyone to understand exactly what has changed. Also, the Architect will normally issue an e-mail summarizing the revisions contained in each addendum, sent simultaneously to the Owner and registered bidders. Information technology is then up to the diverse bidders to convey this information change to their subcontractors and textile providers.

• Question

  In a commercial project, what items are typically called out for shop drawings?

  

  These indicate feature'southward design and dimensions, and commonly include Program views, Elevations views, Sections views, Orthographic views and Axonometric views.

• Question

  What is an existing pole?

  

  An existing pole is a pole which is already in place on building site. That means a new pole is not required and builders may demand to work around this pole when planning and on the construction site. For example, if an existing building is only being refurbished then it is likely there volition be an existing pole.

• Question

  Where am I near likely to find the ceiling height on nigh architectural drawing sets?

  

  Ceiling elevation can usually be constitute in an interior meridian drawing or a section cartoon. You may also find ceiling height in a detail cartoon. If you are dealing with acoustic ceiling tile for example, a detail or tiptop drawing will give you the summit at which the perimeter rails will be installed.

• Question

  What do you call the box on the correct side of a drawing with the info in it?

  

  The "title block" or "data block." This will feature things like the date the drawings were created, the name of the project, the drawing page number (A101, E101, etc.), the architect's company logo, etc.

• Be careful your set of drawings are "original size," since many sets of plans are provided in "full" and "half" size sets, y'all will are able to scale distances with full size drawings without needing to summate the calibration via drafting rulers.

• If the drawings are true half size, y'all volition need to divide your readings from your ruler by 2. Note: near one-half size drawings practice not state they are one-half size or other. Basically to consider anything a half size drawing, it will normally exist less then a 24x18 (Arch C) sized canvas. Keep in mind, sometimes a half size sheet is called a half size even when its plotted from a 30x44 to a 11x17 size set, rendering it no longer a true half size.

• Wait at house programme books or online to get an idea of the lines, measurements, and basic appearance of plans.

• Use a "triangle" blazon architect's or engineer's rule for scaling distances on plans. These are shaped then that they offer a affluent contact with the program page so verbal positioning of the dominion is possible, decreasing the possibility of mistake.

• When doing actual structure from architect's plans, go along one set on-site to record changes with a cherry-red ink pen or pencil. These are called "redline drawings". When a task has been fully synthetic, redlines are usually provided back to the drafter. These drawings are called "Record Drawings" (RDs) or "As-Builts". These are the site survey redlines which are dissimilar from the original fix of drawings (aka corrections).

• Be sure to obtain all necessary building permits earlier whatsoever construction work is started. Building inspectors can end work on any projection that requires a let and does not take one posted. Fines are besides issued.

• When in doubt of a measurement or other description contained in the plans, consult the architect who drew them, rather than taking a chance on an error that can be difficult to correct at a after appointment.

• Be aware that plumbing, electrical, and mechanical plans do not always permit for each trade to have sufficient room in individual locations, then care should be taken to coordinate installation of the components of each trade to avoid conflict.

About This Article

Article Summary Ten

To read an builder's drawings, start by looking at the program index, which should include a key for reading any abbreviations used equally well as a calibration bar so you know the size of the structures in the drawings. Then, use the info in the index to help you examine the floor plans and other drawings. Pay attention to any notes written on the drawing since sometimes it's easier for architects to depict something rather than depict it. To learn about the unlike types of drawings you may encounter, go on reading!
