Plan and prepare for work ARCHITECTURAL WORKING DRAWINGS The architectural working drawings together with the specifications are the most important parts of the documents constituting the contract. Information on the designs, locations, and dimensions of the elements of a building is found on the architectural working drawings while information on the quality of materials and workmanship is found in the specifications. A good architectural working drawing gives the contractor the exact information he needs. It should be clear, simple, and orderly arranged, and accurately drawn so that scaled measurements will match with dimensions. The finished drawings made by the architect, or draftsman and used by the contractor are called architectural working drawings. The architectural working drawings, together with the specifications and the general conditions, form the legal contract between the owner and the contractor. Since the working drawings are a major portion of the contract documents, they should be very carefully drawn. Students will be able to interpret, identify tools and materials used in working drawings and fully understand the standard procedure in layouting and detailing architectural working plans and drawings. 9 Elements of Architectural working drawing A complete architectural working drawing of a house generally includes the following: 1.

This shows the position and the location of the building with property line, setbacks, approaches, grade contours, landscape and other pertinent data in relation to the site. A site development plan is drawn using a scale not smaller than 1:200meters. SITE DEVELOPMENT PLAN 44 SITE is an area of land available for construction or the lot on which a building is constructed. Building site maybe a single lot, a series of lots, or a subdivision. A lot is a piece of ground of specific size. A subdivision is a large tract of land that is being developed. PLANNING CONSIDERATION IN DEVELOPING THE SITE Location of a proposed house on the lot. The location of the house must be considered in order to determine the locations of the rooms and the house itself on the lot. Some lots are located on swampy grounds and others on hilly or rugged terrain. Still others are sited near rivers, highways, streets and squatter areas. The front part of the house generally faces the street or away from ugly views like the back parts of neighboring houses, a swampy area, and thick bushes. Many want their bedrooms to face the sunrise – which is, on the eastern side of the lot. Others, especially those who work at night, prefer their bedrooms located on the west side. The breeze at the site may determine the location of the living room and toilet or bathrooms. The height of the flood waters in the locality should also be considered in determining the distance of the first floor from the ground. This is especially true in low areas. In high locations the floor may be 20 cm. only from the ground level. As earlier mentioned the house may be located at the center of the lot. Or one of its sides may be exactly on a lot line or fence. In this case, a firewall which is made of concrete, adobe, and concrete hollow blocks should be constructed on this side of the house. Like and dislikes of the family member. This factor is usually considered when the family is rich and can afford to pay for the services of an architect or draftsman. Before he designs the house, the architect or draftsman has to first interview the members of the family to get information about their interests, hobbies, and the like. From such interviews, he will get to know whether the family wants a library or study room, a social hall, a playroom, a music room, a swimming pool, a 45 carport or garage, servant’s quarters, a driver’s room, a landscaped garden, a balcony, and a roof garden. Property Lines are those lines working outside of the lot area. Setback refers to the distance at how far a building can be built within the property lines. Zoning refers to the legal restrictions on size, location, and type of structures to be built on a designated area. 46 Zoning Laws One major area covered by building code is the zoning laws. Zoning laws are designed to keep different areas of a community from interfering with each other. In some cities or towns, separate areas are set aside for specific uses. Examples are residential, commercial, and industrial. These are established and protected by zoning laws. In addition, zoning laws establish standards for construction in different sizes and uses. One of the first things an architect must do before designing a building is to read the building codes. The intended use of the building has to be within the limits of zoning laws. Also, the size of the lot must be large enough to meet the requirements. Building Code are local laws that set standard for structural design within the community. This is a collection of local laws that regulate the building of homes and other structures. These legal requirements are intended to protect the safety and health of the people who live and work in the buildings. They regulate restrictions concerning the construction of buildings to provide safety to the occupants. All constructions in an area must meet the requirements of building codes. Some of the designs and construction features covered by building codes include: Qualifications of persons who can design building within the area. Structural design that can be used Lot sizes for certain types of buildings Types and sizes of materials that can be used. 47 National Building Code Rules: 1. For one-storey wooden or frame house, the height of the floor plan from the ground should not be less than 1.50 m. 2. Walls with window opening should not be less than 2.00 m. from the lot line of fence. In other words, adjacent houses should not be at least 4.00 m. from each other. 3. The front part of a house should not be less than 3.00 m. from the lot line along the street. 4. No windows should be constructed along a wall of a house if this wall is flush with or exactly on the lot line. 48 ACTIVITY SHEET # 3.1 LO3.

INFORMATION SHEET 4.1 64 L.4. FLOOR PLAN FEATURES Floor Plan Floor plan is the top cross-sectional view of the floor area of a house. The horizontal cutting plane line for this top view passes between the upper and lower window sills or one meter above the floor line. It shows the size and arrangement of the rooms. It also presents the sizes and locations of the stairs, door and windows openings, and partitions and walls. Sometimes it includes the kind of furnishings in each room. However, the materials required for constructing permanent or integral parts of each room such as bedroom closets, kitchen cabinets, etc., should also be accounted for in the bill of materials. B EAVE LN.. A A B FLOOR PLAN SCALE: 1:100 M. In multi-storey buildings, a separate floor plan is drawn for each floor level when the layout of the room is not in each floor. However, when two or 65 more floor levels have the same arrangement and features, one typical floor plan representing all the identical floors will suffice to be drawn. Room Requirements and pointers in planning a floor plan 1. Living Room is the center of the living area in most homes. It should be centrally located and should be adjacent to the outside entrance and to the dining area, but the entrance should not lead directly into the living room. Recommended sizes should be at least 2.00m x 3.00 small, 3.7m. x 5.5m. average or optimum size would be 6.1 x 7.9 m. in rectangular shape. 2. Bedroom is a room for sleeping and taking rest of the family. Ideal number of rooms for low cost housing should be two bedrooms, master’s bedroom and bedroom. Preferably, there should be a toilet and bath in master’ bedroom and a built-in cabinets or closets. 3. Dining Area is the area where greatly depend on eating habits of the occupants. This should be located between the living room and kitchen. Its size and shape are determined by the size of the family. 4. Kitchen is the place for preparation of food and connecting the work triangle area for storage and mixing center, preparation and cleaning center and cooking center. There should be a storage hanging kitchen cabinet with a minimal width of 0.60 meter. Types of Kitchen 66 1. U-shaped kitchen 67 2. . L-shaped type 3. Corridor type 68 5. Bathroom is where the toilet and tub or shower are separated to save economically in plumbing. As much as possible keep the toilet near 69 the kitchen. The bath and toilet must be near the bedrooms, accessible to the living room even without passing through other rooms. The toilet and bath are generally located between bedrooms. In a two-storey residential house, the bedrooms, toilet, and bath are often located on the second floor. In this case, the stair must go up from the living room or hall if there is any. The stair is generally L or U-shaped and has a landing. Bathroom Doors and Windows Bathroom door could be small as 5560 cm. except for utility bathroom which requires not less than 70.cm. wide to allow passage of equipment as required. In general, bathroom wall contain only one door. 6. Entrances Entrance is divided into several different types; the main entrance, the service entrance, and the special- purpose entrance. The entrance is composed of an outside waiting area like the porch, marquee or lanai and an inside waiting area like foyer or entrance hall. It provides for and controls the flow of traffic into and out of a building. The main entrance provides access to the house. It is the one through which guests are welcomed and from which all major traffic patterns radiate. The main entrance should be readily identifiable. It should provide shelter to anyone awaiting entrance. The service entrance provides access to the house through which supplies can be delivered to the service areas going through other parts of the house. It should also provide access to parts of the service area like the garage, laundry or workshop. The special-purpose entrances and exits do not provide for outside traffic. Instead they provide for movement from the inside living area of the house to the outside living areas. A sliding door from the living area to the patio is 70 a special-purpose entrance. It is not an entrance through which street, drive, or sidewalk traffic would have an access. 7. Garage and Carports. A garage is an enclosed structure designed primarily to shelter an automobile. It maybe used for many secondary purposes – as a workshop, as a laundry, or for storage space. It is usually attached to the house in some manner to provide a sheltered entry. A carport is a garage with one or more of the exterior walls removed. It may consist of a free-standing roof completely separate from the house, or it may be built against the existing walls of the house. SELF CHECK 4.1 71 LO4.1 Floor Plan features Direction: A.

Use of appropriate scale in drawing a Floor Plan Scales The architectural draftsman normally uses an architect’s scale for reducing and enlarging the scale size measurement. There are two system of measurement, Metric system and English system. Metric System 73 Always remember that the smallest the number used in metric scale, the bigger the size in the triangular scale whereas, the largest the number used the smallest size of actual measurement. 1:05 m. 1: 100 m. 1:10 m. 1: 200 m. 1:20 m. 1: 300 m. 1: 30 m. 1: 400 m. 1: 40 m. 1: 500 m. 1: 50 m. 1: 600 m. 1:75 m. 1:1000m. Note: The scale of 1:1000 m. or more is being used in Lot Plan and other topographical drawings. Full size scale The 1:1 is a full size scale and each division measures 1 mm. in width with the numbering of the calibrations at 10mm intervals. This same scale is convenient for ratios of 1:10, 1:100, and 1:1000 Half size Scale The 1:2 is one-half size scale and each division is equals to 2 mm. with the calibration numbering at 20-unit intervals. In addition, this scale is convenient for ratios of 1:20, 1:200, and 1:2000.

Size and Dimension of Rooms: a. Room for human habitations should be 6.00 square meters with at least a dimension of 2.00 meters. b. Kitchens should be 3.00 square meters with at least a dimension of 1.50 meters. c. Bath & Toilet – 1.20 square meters with at least dimension of 0.90 meters. Section 1207. Stairs, Exit, and Occupant Loads. Width and Height. Every required exit doorway shall have a size to permit the installation of a door not less than 900 millimeters in width and not less than 2.00 meters in height. Stairways width. Stairway serving an occupant load of more than 50 shall not be less than 1.10 meters. While stairway serving an occupant load of 50 or less shall be 900 millimeters wide. Rise and run. The rise of every step in a stairway shall not exceed 200 millimeters and the run shall not be less than 250 millimeters. Other guidelines must be observed in the arrangement of rooms in drawing floor plan: 1. Built-in cabinets or closets are usually found in the bedrooms, kitchen, and dining room. Open shelves may be constructed in the kitchen and dining room. 2. In some one-storey houses, the bedrooms toilet, and bath are elevated from the other rooms. In this case, the stairs leading to these rooms must be indicated on the floor plan. Two or three steps, each has 18 or 19 cm high from each other and 25 cm wide, may be shown in the plan. All these measurements must be drawn to scale. 77 3. Since most of the time is spent by the members of a family in the bedrooms at home, these rooms must be located far from noise, dust, and polluted air coming from garbage pits or from the kitchens and toilets of the neighboring houses. 4. If furnitures and house appliances are to be shown in each room, these furnishings should be drawn on the same scale in the floor plan. 5. If the floor plan will be traced on tracing paper in order to indicate the electrical or water connections, these furnishings should not be shown on the tracing. 6. In presentation drawings, the landscaping around the floor plan may be added. 7. It is on the floor plan where the cutting plane lines for at least two full-sectional elevations (cross and longitudinal) are indicated. These sectional elevations are usually labeled as Section A-A and Section B-B, depending on the capital letter used at the extremities of the cutting plane lines. These cutting plane lines need not be continuous or straight. They are often drawn in colored ink. ( see illustration) 8. Windows and Doors symbols should be indicated in the outer walls of the floor plan opposite to door and windows openings to determine the total number and specification. Entrance and Exit. There shall be at least one entrance and another one for exit. Windows opening should be 10% of the total floor square area according to the National Building Code. Example: Bedroom size of 3.00m x 40.00 = 12 square meters x 10% = 1.20m window width opening. Concrete Hollow Blocks (CHB) for walling and partitions Sizes: 78 CHB - 0.10 T x 0.40 W. x 0.20 H. (4” T x 16”W x 8”H) is used for interior walls or sometimes exterior wall with no heavy loads. CHB - 0.15 x 0.20 x 0.40 (6” x 8” x 16”) is used for exterior wall sometimes for interior wall. Plastering of CHB wall should not be less than 0.015 mm. or not more than to 0.05 cm in thickness. Note: In lay outing floor plan walls, it should be scaled with same sizes of all actual materials to be used. If the occupancy wants to use 0.10 x 0.20 x 0.40 CHB plus plastering of 0.015 mm thickness on both side walls, the total thickness of the wall is 0.13 cm. On the other hand, likes to use 0.15 x 0.20 x 0.40 CHB plus plastering of 0.015 mm thickness on both sides a total average is 0.018 cm. since it is very hard to layout the accurate scale of 0.18 wall thickness, so most draftsman prefer to use 0.20 cm. wall in lay outing floor plan. Wall Openings Entrance door is preferably with 0.90 cm. to 1.00 m. width. Bedroom door has a minimum width of 0.80 cm. Toilet and Bath door have a minimum width of 0.70 cm. to 0.80 cm. Minimal width of windows is preferably 0.60 cm. Other appliances and fixtures are required to be drawn in the floor plan for space requirements Eave lines are hidden roof lines which also indicated in the floor plan.

Draft Roof Plans 93 Definition of technical terms Angle iron is a structural piece of rolled steel shaped to form a 900 angle. Butterfly roof is a roof with two sides sloping down toward the interior of the house. Dome is a hemispherical roof form. Dormer is a structure projecting from a sloping roof to accommodate a window. Eave is a part of a roof that projects over a wall. Fascia is a surface finish material used to cover another surface. Flashing is the material used for covering exposed places outside the building like firewalls. Flat roof is a roof with a minimum pitch for drainage. Gable is the triangular end of an exterior wall above the eaves. Gable roof is a roof that slopes from two sides only. Galvanize is a lead and zinc bath treatment to prevent rusting. Gambrel roof is a symmetrical roof with two different pitches or slopes on each side. Hip rafter is the diagonal rafter that extends from the plate to the ridge to form the hip. Hip roof is a roof with four sloping sides. Mansard roof is a roof with two slopes on each sides with the lower slope much steeper than the upper. Overhang is the horizontal distance that a roof projects beyond a wall. Pitch is the angle between the top plate and the ridge board. It is also referred to as the rise over the run. Purlin is a horizontal structure member which hold rafters together. Rafters are structural members used to frame a roof. Ridge is the top edge of the roof where rafters meet. Ridge cap is a wood or metal cap used for roofing at the ridge. Rise is the vertical height of a roof. 94 Roll roofing is a material of fiber and asphalt manufactured in rolls. Shed roof is a flat roof slanting in one direction. Shingles are thin pieces of wood or other materials that ovelap each other in covering a roof. Truss is a prefabricated triangular shaped unit used for supporting roof loads over long spans. Valley is the internal angle formed by two slopes of a roof. Valley rafter is the diagonal rafter forming the intersection of two sloping roofs. Roof It is the external upper covering of a house or building. It shows the size, shape and the type of materials that should be used in the roofing system. Types of Roofs There are different types of roofing system that are commonly used in the building construction. The following are: 1. Gable Roof has a pitch on two sides but no pitch on the gable ends. This type of roof is used extensively on Philippines bahay kubo and raw houses in subdivision. The pitch or angle of a gable roof varies from the high pitch roofs found on chalet A-frame style buildings to the low pitch roofs found on most ranch homes. 95 GABLE ROOF 2. Hip roofs are used when eave-line protection is desired around the entire perimeter of the building. Hip roofs are very popular in warm climates. they are commonly used on Regency and French Provincial homes. HIP ROOF 3. Flat roofs are used to create a low silhouette on modern homes. Slightly heavier rafters are needed for flat roofs. Built-up asphalt construction is often used on flat roofs. 96 FLAT ROOF 4. Shed roofs are higher at one end than the other. They may be used effectively when two levels exist where additional light is needed. SHED ROOF 5. Overhang is a roof type where the pitch is low and extends on the side of the building perpendicular to the rafters direction. It should provide additional protection from the sun and rain. 97 OVERHANG ROOF These five roofing system are commonly used in the construction sector. However, there are other types of roofs that are rarely used in the construction. INFORMATION SHEET 5.3 LO5. Draft Roof Plans 98 Roof Plan A roof plan is one showing the outline of the roof and the major object lines indicating ridges, valleys, hips and openings. The roof plan is not a framing plan, but a plan view of the roof. To develop a roof framing plan, a roof must be stripped of its covering to expose the position of each structural member and each header. The roof plan can be used as the basic outline for the roof framing plan. Below are samples of blueprint drawings of roof plans, roof framing plan and other informative drawings. SAMPLE ROOF PLAN 1. Roof Plan The roof plan indicates the following: a. Roofing sheets are materials laid to cover the total area of roofing space of the building. b. Ridge roll is a plain G.I. sheet is usually laid at the center top of ridge of the building. c. Ridge cap the material used the roofing Elements or is features of roof andwhen framing plans system is in the form of hip roof. d. Eaves line or gutter line is shown in the form of imaginary line to indicate the gutter line. 99 ROOF PLAN Different types of roofing sheets: 1. Corrogated G.I sheet 2. 4-V corrugated sheet 3.

Ventilation is the process of supplying and removing air by natural or mechanical means to or from any space The Importance and Purpose of Ceiling in the building 116 Ceiling plan is an outline of the ceiling that shows the overhead interior surface of a room. Ceiling is designed with the following purpose: i. It prevents the penetration of the heat of the sun inside the building. ii. It adds beauty inside the building especially when it is well-designed. iii. It serves as thermal insulator that adds to the aesthetic beauty of a house. iv. Various lighting fixtures can be hanged or placed to highlight the interior design of the structure. Important features that are shown in the ceiling plan Ceiling plan can be shown into two presentations: a. Ordinary presentation of ceiling plan. This shows the following: 1. Ceiling board 2. Partitions 3. Ventilation 4. Label which indicates the type of ceiling materials 5. Dimensions b. Reflected ceiling plan. It is a drawing, which shows the items that are located on the ceiling of a room or space. It is referred to as a reflected ceiling plan since it is drawn to display a view of the ceiling as if it was reflected onto a mirror on the floor. This way the reflected ceiling plan has the same orientation as the floor plan associated with it. It is as if the ceiling was see-through and you could see right through it from the floor below. Interior designers draw reflected ceiling plans when designing spaces. The following features that are shown in the reflected ceiling plan: 1. Lighting fixtures 2. Ventilation 117 3. Smoke detector 4. Wood moulding 5. Ceiling board Important considerations in ceiling plan There are many design elements to consider in designing the ceiling plan 1. Consider the distance from floor line to ceiling line level. 2. Study the 3-D aspects of volumes and space. 3. Consider using unexpected materials or finishes. 4. Consider the light reflection and sound absorption. In accordance with the National Building Code of the Philippines (PD 1096) Section 805: Ceiling Heights v. Habitable rooms provided with artificial ventilation have ceiling heights not less than 2.40meters. which is measured from the floor to the ceiling; provided that for buildings of more than one-storey, the minimum ceiling height of the first storey shall be 2.70meters. And that for the second storey 2.40 meters and succeeding storey shall have an unobstructed typical head-room clearance of not less than 2.10m above the finished floor. vi. Mezzanine floors shall have a clear ceiling height of not less than 1.80meters above and below it. OPERATION SHEET 6.1 LO6 DRAFT CEILING PLAN 118 Ceiling Plan is shown in outline form.

Draft Elevation and Section 126 An architectural elevation is a view of a building showing its height dimension. When elevations show the exterior of a residential unit, they are simply called elevations. Interior elevations show the inside of a building. Elevations are the exterior views of a building. They are necessary in as much as they show the height of the building and its appearance on each side. Normally, the four elevations are sufficient to describe the appearance of the residential building. Elevation drawings are orthographic drawings. They show the exterior of a building. The elevation s that part of the building that people see and observe, hence, it is the part they use to judge the structure. Normally, the design of the floor plan precedes the designs of the elevation, because both have a continual relationship in the entire design process. Flexibility is possible in the design of elevations, even those designed from the same floor plan. The designer should keep in mind that only horizontal distances can be established on the floor plan, while that of the vertical distances such as height of doors, windows and roofs must be shown on the elevation. As these heights are established, the appearance of the outside and functioning of heights as well as the internal functioning of the building must be considered. Preliminary Sketches The location and proportion of features are very important in the drawing of elevation. Main attention is given to the proportion of walls and openings. Some of the things to consider in the drawing of elevations are; 1. Proportion – which deals with the size and shape of areas and their relation to one another. 2. Fenestration – deals with the arrangements of windows and doors in a wall. 3. Harmony refers to all features that should harmonize to present a uniform elevation. 4. Shadows refer to a simple elevation, which can become interesting when designed to take advantage of shadows. Finished Sketches 127 The finished sketch may be carefully drawn with the use of drawing instruments. Since these are fairly large scale drawings the exact size of all features together with their correct representation must be considered. In the drafting of elevations, these are some of the things to consider: 1. Window and Door Size – must be chosen from a manufactures catalog which offers great variety of sizes. The sizes must be standard that it conforms to the provisions of the building code. 2. Window and Door Representation –in elevation may be drawn simply. 3. Material Representation – may be shown by drawing only a few lines, like bricks. 4. Footings and Walls are hidden lines used to indicate location of footings. 5. Labeling views can be done in two methods by labeling it with views as in front, rear, left and right side elevations, or by using compass orientation as in north, south, east, and west directions. 6. Dimensioning on elevations are limited to vertical dimensions are shown on the plan. 7. Changes are additions necessary after all the other drawings have been completed. Elevations are the exterior views of the building. The front view of the building is always referred to as the front. The other elevations are named according to their position in relation to the front, i.e. right elevation, rear or back elevation, left elevation. 128 Eave is the lower portion of a roof which extends beyond the wall. Pitch is the term applied to the amount of roof slope, It is found by dividing the heights of the span Elevation Projection Elevation drawings are projected from the floor plan of an architectural drawing just as the views are projected the front view of an orthographic drawing. All six views are rarely used to depict architectural structures, instead only four are used. These four elevations are normally projected on the floor plan. 129 FLOOR PLAN 130 FRONT ELEVATION REAR ELEVATION 131 LEFT SIDE ELEVATION RIGHT SIDE ELEVATION Elevation Dimensioning Dimensions on elevation show the vertical distance from a datum line, which is a reference line that remains constant. Dimensions on elevation show the height above the datum or the ground line. Dimensioning 132 elevations must comform with basic standards to ensure consistency of interpretation. Here are some of the rules in dimensioning: 1. Vertical elevation dimensions should be read from the right of the drawing. 2. Levels to be dimensioned should labeled with a note, term or abbreviation. 3. Room heights are shown by dimensioning from the floor line to the ceiling line. 4. The depth of footings (“footer”) is dimensioned from the ground line. 5. Heights of windows and doors are dimensioned from the floor plan to the top of windows or doors. 6. Elevation dimensions show only vertical distances (height). Horizontal distances (length and width) are shown on the floor plan. 7. Windows and doors may be indexed to a door or window schedule, or the style of the windows and doors may be shown on the elevation drawing. 8. The roof pitch is shown by indicating the rise over the run. 9. Dimensions for small, complex or obscure areas should be indexed to a separate detail. 10. Ground-line elevations are expressed as heights above a datum point. 11. Heights of chimneys above the ridge line are dimensioned. 12. Floor and ceiling lines are shown with hidden lines. 13. Heights of planters and walls are dimensioned from the ground line. 14. Thickness of slabs are dimensioned. 15. Overall height dimensions are placed on the outside of subdimensions. 16. Thickness of footings are dimensioned. 17. Where space is limited, the alternative method in Fig.38-2 can be used to show feet and inches. 133 SELF CHECK #7.1 134 Directions: Fill in the blanks with the correct answer and write it on a separate sheet of paper 1.

Lay-out the elevation very lightly using a sharp, hard pencil. Using a divider or a scale, transfer horizontal dimensions from the floor plan. A scale of 1: 100 or 1:50 meter is used and indicated in the title block or near the drawing. If the plan and section are drawn to the same scale as the required elevation, the floor plan may be taped in position and dimension projected directly using triangle and T-square. Windows and door are located horizontally by projecting from the plan, They are located vertically by projecting from the window and door details or simply by aligning the top of the window with the top of the door. 2. Locate the vertical distance of ceiling from floor line, ridge to ceiling line and natural ground to finished ground line. indicate also the height of doors and windows. 3. Indicate the thickness of walls, fascia board and other materials seen on elevation and darken the lines to highlight them. 136 4. Draw the elevation details and other architectural materials. The elevation details to be included will vary depending upon the style of the house, in the case of a residence, the following details are added: 1. roof fascia 2. roof beams 3. window representation 4. gradelines 5. material representation 6. darkened building outline 5. Indicate the dimension of the vertical distance from the natural ground line to the floor line and the floor line ceiling, and ceiling line to ridge line. 137 Added elevation dimensions and notes are. 1. height of roof 2. height of other features such as masonry wall 3. heights of wall 4. roof slope indication 5. window schedule 6. title and notes indicating materials INFORMATION SHEET # 1.2 LO7. Draft Elevations and Sections 138 Sections The designer shows the internal construction of a building by means of a section. Section drawings are prepared for interior details needed to guide construction. Interior elevation drawing shows builders how to construct and install special features of a home. These features include closets, cabinets, bathtubs and other special details. Techniques for preparing interior elevation drawings are the same as for exterior elevations. Use a floor plan to locate key vertical lines after horizontal dimensions have been indicated. Section is a type of drawing which shows the interior or inside of a building or structure. Cross section is a type of section where the cutting-plane line is drawn horizontally. Longitudinal section is a type of section where the cutting-plane is drawn vertically. Cutting plane line a heavy line which shows the exact location where the plan is cut. The following are the types of sections used in architectural drafting. 1. Structural section shows the entire building construction. This is useful in planning for structural strength and rigidity, determining the length of members and specifying sizes. 2. Wall section shows the construction of a typical wall. This section is useful in determining sizes and material specification for all rough members. 3. Detail section shows any deviation from a typical section. It is drawn to a larger scale. 139 140 141 Full Sections 142 Architects prepare drawings that show the building cut in to half to show the internal structure. This is known as longitudinal section, meaning lengthwise. When it is cut across, it is called transverse section. It is imagined that a plane is passed through the building cutting it in half by a cutting plane line. There are different ways of drawing the cutting plane line, most especially if it interferes with dimensions as shown in these figures. 143 144 SELF CHECK #. 7.2 145 Directions: Based on the given floor plan, draw the front and rear elevations. Use a separate sheet of paper OPERATION SHEET # 1.2 146 LO7. Draft elevations and Sections Drafting Section Procedure: The student will draw the activity individually and they will be provided a copy of the floor plan. The student will draw the sections; the cross section and longitudinal section. The activity will be for 2 meetings or four hours. 147 1. From the given plan, indicate the path of the imaginary cutting plane along the floor plan. Indicate the position of the line of sight or viewing by means of arrow heads. 2. Transfer horizontal dimension from the floor plan to the section using a metric scale with appropriate scale ratio. 148 3. Indicate the vertical dimensions from the ground line to the floor line, the ceiling line and the ridge line using the standard vertical dimension as provided in the low cost housing regulations. The standard dimension are 2.80m from the floor line to ceiling line and 1.20m to 1.80m from ceiling line to the top of the ridge. 4. Draw the outline of the building using the measurements as marked on the paper. 149 5. Darken the outline and draw section lines on portions of the building that come in contact with the cutting plane. 6. Finalize the drawing by labeling it. 7. Repeat the same procedure for the cross section drawing. 150 Program/Course : DRAFTING TECHNOLOGY Unit of Competency : DRAFT ARCHITECTURAL LAYOUTS AND DETAILS Module Title : DRAFTING ARCHITECTURAL LAY OUTS AND DETAILS Learning Outcome 8 Assessment Criteria : Perform Presentation Drawings : 1.

Perform Presentation Drawings Presentation drawings The purpose of the presentation drawings is to show the proposed building in an attractive setting surrounding at the proposed site. It must be shown in an attractive presentation to easily arouse the client’s interest. Presentation drawings consist of the preliminary designs: 1. Floor plan 2. Elevations plan 3. Perspective 4. Sections 5. Sample details The floor plan must be presented to the client to give him a clear picture of interior portion of the proposed building particularly the location of bedrooms, living room, dining, kitchen, comfort rooms and other elements inside the building. 153 The elevation plan is purposely to show the height of the building particularly the distance from floor line to ceiling line and the distance from bottom line and top of a ridge.

GUTTER LONGITUDINAL SECTION Commonly, presentation drawings are usually presented in the form of perspective views with colors and shading and floor plan. This is purposely done because presentation drawings are actually used to sell an idea or concept. The elevation plan, section and sample details are only used for further communication between the clients and the architect or draftsman to arrive at a final plan or design of the house. These are usually shown in the form of illustration. PERSPECTIVE DRAWING 155 Perspective Drawing The following are important principles to be considered in the preparation of presentation drawings particularly perspective views, the following are: 1. Selection of appropriate view of the proposed building In the presentation, the frontal portion must be given more emphasis by the designer because this is the very part of the building that is always exposed to the viewers’ eyes. 2. Proportion of the perspective view This means that proper location of the vanishing point must be considered in making the perspective view. 3. Inclusion of landscaping Landscaping must be included in the preparation of perspective view because it adds attraction to the viewer. 4. Other elements like car, human figure and etc. must also be included in the presentation of perspective view because these would serve as additional attraction of the drawing. 156 OPERATION SHEET # 8.1 LO8. Perform Presentation Drawings Presentation drawing is commonly accomplished in the form of perspective view especially when the draftsman or architect is negotiating a drafting service to a certain client. However, floor plan, elevations plan and section drawings are also prepared to be shown to the client. The following are the procedures in the preparation of presentation drawing: 1. Draft the floor plan according to the desired size and shape. 2. Draft the elevation plan based on the floor plan. 3. Draft section drawing based on the elevations and floor plan. 4. Draft the perspective view. 157 ANSWER KEY LO1. Plan and prepare for work Self Check 1.1 1. Triangle 2. Divider 3. Tape rule/Pull-push rule 4. Templates 5. Masking tape 6. Medium 7. Compass 8.
