Program/Course : TECHNICAL DRAFTING NC II Unit of Competency : DRAFT ARCHITECTURAL LAYOUTS AND DETAILS Module Title : DRAFTING ARCHITECTURAL LAYOUTS AND DETAILS Learning Outcome 6 : Draft Ceiling Plan Assessment Criteria: 1. Elements or important features of ceiling plan are properly identified. 2. Ceiling plan is drawn according to architectural drafting standards. 3. Lighting fixtures and fire protection devices are located according to architectural drafting standards.  INFORMATION SHEET 6.1 LO6. DRAFT CEILING PLAN Definition of Terms Acoustic is the science of sounds in housing, materials used to keep down noise within a room or to prevent it from an overhead lining inside of a room Ceiling Joist is the structural member in building construction that holds the ceiling board Ceiling board is a ceiling covering materials Cornice is a wood or any material project beyond the wall of the ceiling Fixtures is a piece of electric or plumbing equipment which is a part of the structure Gypsum board is a board made of plaster with covering of paper Hanger is an iron or wood strap used to support a joist. Insulation is a material obstructing the passage of sound, heat, or cold from one surface to another Lighting fixtures is the position or placement of lighting fixtures of the house. Reflected ceiling plan is a drawing of a room or building, looking down at the interior ceiling Smoke detectors is a fire protection device that is used to detect smoke or gasses produced by smoldering fires particles of combustion Soffit is the undersurface of a cornice, molding, or beam Specification is the written description accompanying the working drawing Sprinkler systems is a fire protection device that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been reached. 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 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 4. Label which indicates the type of ceiling materials 2. Partitions 5. Dimensions 3. Ventilation 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 4. Wood molding 2. Ventilation 5. Ceiling board 3. Smoke detector 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. STEPS IN DRAFTING CEILING PLAN Ceiling Plan is shown in outline form. It is made with the floor plan as its reference outline. 1. Prepare and set a ready-made floor plan and analyze its size and shape. 2. Sketch the ceiling area based on the general measurement of the floor plan. 3. Provide space for overhang for the four sides at your desired size. 4. Sketch the partitions based on the measurements in the floor plan. 5. Darken all the visible edges, indicate the dimensions and label the necessary information.
