sample floorplan for understanding house blueprints



A must click to follow your how to build your house list... Do you understand house blueprints, they are the plans to your home, I like to take the time and look for errors... the designer has taken your ideas and formulated your house plans.

As in every aspect of building, communication is the hardest part, so take the time now to look at the house design. Does it fit with your image of the house you want. Make all the changes now..not later while project is being built... as soon as you change during construction... costs escalate dramaticaly. You must refer all changes to the designer: Remember -larger drawing takes precedence over smaller drawings -specifications take precedence over drawings -check drawings for conflict re ductwork, plumbing, electrical, windows and door sizes -note last date of change

Blueprints re: survey plans should show the following information: -property survey plan or survey certificate -legal description of property -name of owner -name of surveyor -location of property -size of property -buildings on property -north -encroachments

Blueprints reading definitions: -Abbreviations are only in capital letters ending in a period

-Blueprint break line is: solid, hill, valley, solid is used to shorten object lines over a typical space

-Blueprint center line is: long dash, space, short dash , space, long dash.. . center line is used to show center of partitions doors, windows. .grid lines

-Blueprint cutting or section line is solid space dash space dash solid .. arrows pointing to cut area for sectional view

-Blueprint dimension line: ends in dots, or arrows, or slashes on extension lines.. dimension lines shows measurement

-Blueprint extension line: project to dimension line

-Blueprint hidden object line: hidden line indicated by ------- dashes

-Blueprint object lines: objects are ____________ dark solid

-Blueprint scalegiven in title block or directly below drawing common scales 1:50, plot 1:200

Blueprints also use symbols: doors, windows, electrical, plumbing, appliances, stairs, etc.

Blueprints, Architectural Plans: show overall design and finishing details.

Blueprints, As built drawings:to be kept as records as to how the building was built, giving locations of mechanical, electrical and other services. Not usual in small house.

Blueprint details are: an enlarged view of sections or cross sections showing much detail.

Blueprint electrical plan: show the electrical wiring, telephone, schematics

Blueprint elevations are: the vertical plans showing the exterior or interior walls

Blueprints isometeric is: a pictorial

Blueprints mechanical plan show the heating and plumbing systems

Blueprints viewed from above are the floor plans... this top view is a cutting at about the 5 foot elevation of the wall eye level dashed lines show hidden objects below cut

Blueprint side views are elevations

Blueprints a set of prints should be laid out in six views, centre is front, below front is bottom, above front is top, right of front is right side, left of front is left side, left of left side is back

Blueprints while reading -write notes -use different colors to highlight areas -take notes on the take off -no matter how simple lay out a plan -check for details in structural and architectural... drawings can be intentionally obtuse

Blueprint schematics show the layout by a series of lines, symbols, notations and measurements usually for electrical or plumbing lines

Blueprint sections are cuts through plan -vertical views of a plan elevation are longitude cuts -horizontal cut of plans... view is called transverse

Blueprints specifications -introductory information list of drawings list of schedules -bidding information, bid forms, agreements and bonds, specifications are part of the contract documents, they are broken into 16 areas

#1-general requirements: pay schedule, insurance, signs, damage, safety, clean up, quality, product, execution

#2-site work: top soil, rock excavation, trenching, trucking, grading, back filling, shoring, footing drains, mechanical, drainage, paving, utilities, restoration

#3-concrete: materials and methods, types, strength, curing, shoring, finishing, rebar, forms accessories, mass , restoration

#4-masonry materials and methods

#5-metals materials and methods, steel workers, structural steel, joists , decks ornamental

#6-carpentry, woods and plastic, material and methods, rough, finish, architectural, restorations

#7-thermal and moisture protection, materials and methods damp & water proofing, insulation, shingles & rolled & membrane roofing flashing caulking, fire and smoke protection

#8 -doors windows glass methods and materials

#9-finishes: all exterior interior finishes methods and materials , metal support assemblies, plaster, gypsum, tile, terrazzo, ceilings, walls, acoustical, paints

#10- specialties: items required for the building example washroom hardware, louvers, vents, service walls, access flooring, accessories and specialties

#11 - equipment, security, theater, banking, check room, vending , waste handling, loading dock, water supply, commercial laundry, office food etc.

#12-furnishings: office, planters, casework, etc.

#13-special construction: specialized construction: ice rinks, pools, etc. etc.

#14-conveying systems: elevators , escalators, transportation

#.15-mechanical, heating, air, plumbing, fire protection, refrigeration

#16-electrical: television, telephone, security, intercom, lighting, wiring methods often general conditions are included in with the specifications

Blueprints structural (or engineered) show the structural components

Blueprints zoning regulations: type of building, (store, dwelling, etc.) maximum ground coverage, setbacks, green space, codes, permits

Blueprint plot plan or legal survey:

-are required drawing for permits

-iron pin is driven below grade to mark corner of property

-lead plug is used instead of iron pin such as in a bedrock situation

-survey point also called hub are physical markers used to set up the instrument (driven into ground to protect)

-corner stakes temporary corner markers for construction

-witness stake is an offset of the iron pin or any hub

-benchmark can be actual elevation set from a datum point or a made up elevation set at zero or often 100

-bench marks are used for building elevations

-Your survey blueprints can show: legal description, surveyors name, scale, property line, bearings, measurements, buildings, topography, elevation above sea level, contour lines, contour intervals, dashed lines for existing grades, solid lines for finished grades, benchmark for finished floor elevations, easements, setbacks, walks, drives, utilities,

-specifications are the written part of the blueprint documents which set out the detail in precise nature of work and materials.. defining the quality of work to be done...specifications should match drawings and any items that do not coincide should be referred back to owner/architect.. the specifications spell out responsibilities of those invloved...technical specifications

Second example showing contours of lot.


NOTES: - the IP in corners of lot designate iron pin or surveyors stakes

- the contour lines indicate elevations usually referenced to a near by point

-often you will see elevation points labeled:TW.=top of wall, TS.= top of slab, FG.= final grade etc.

- the compass point shows North

-the deminsions or set backs for the building position on lot are given from lot line to outside of house

-house dimensions are shown to centre of walls

-local road and civic address should be included in the title block for this page

- if available utility lines, poles, sewer and water should be shown

-if part of the contract sidewalks and driveways can be indicated
