RCC drawings 1. Checking dimensions and unit - Linear dimensions should be expressed in millimetres (mm) on building drawings and in metres (m) on site plans. According to the standard convention In drafting, the unit symbol can be omitted if the following requirements are met: 1) A note indicating the unit used is displayed in a conspicuous place on the drawing the sheet; 2) All linear dimensions including those for spat level and land elevation are given one dimensioning unit only, -
-
-
-
For easier reading, group the digits in triads on both sides of the decimal marker (e.g., 123 456.789). All dimensions shown in metres must be taken to three decimals places, even when all dimensions are zero. (eg: - 1.225, 0.000) . Area dimension should be expressed in m2 to two decimals for floor area of rooms, cross section areas of earthwork, etc. & should be expressed in mm2 using no decimals for structural members and other sections bars, etc. Symbols of these units must always be shown on drawings where appropriate. Volume dimensions should be expressed in m3 for volumes of earthwork, excavations, concrete, fluid in large quantities and in (Litre) for volume pertaining to liquids and gases only. Symbols of these units must always be shown on drawings where appropriate. Other units used in structural calculations and drawings should be expressed as follows : - Pressure, loads and stress : MPa - Mass in Kg or Tones or KN. - Bending Moments in kNm - Section moduli in mm3 & MI in mm4

Notes Scale will vary but it is recommended that preference be given to those used in the working drawing stage..
Preferred scale is 1:50
*The recommended range of scales may be extended to both sides, provided that the new scale can be derived from a recommended scale by multiplying numerator or denominator by a power of 10. 3. General notes Design Note : Refer to the building codes and other requirements for bylaws according to which the structural design has been executed. Comment on EQ designs where appropriate. Soil Note: Comment on or quotes from soil investigation report for the given building site. Concrete Note : Contains information on grade of concrete for various structural members, compressive strength , etc. Special note should deal with expansion joints in concrete and masonry. Formwork Note : Describes requirements for the preparation and removal of concrete formwork. Backfilling Note : State conditions for backfilling and acceptable types of back fill material. Steel Notes Reinforcement Steel : Specifies the type and grades of reinforcement steel and requirements of it’s bending, lapping & placing. Structural Steel : Specifies types and grades of steel for structural members and requirements for bolting or welding them.
Masonry Note : Describes the masonry units to be used, the type of mortar, masonry anchors and reinforcement when required and the bearing capacity of the masonry walls. Structural Lumber Note : Specifies the requirements for lumber and lumber assembly grades to be used, and where required, fastening and special lumber treatment. Lintel Notes : Describes the cover material and any necessary reinforcement and anchoring of all lintels in concrete, masonry and wood frame walls. 4. Site Reference Plan When structural work is required outside the building, prepare a site reference plan showing the location of structural elements on the site. Refer to this plan for foundation details, sections, reinforcement schedule, etc. regarding all retaining walls, underground tanks, outside stairs, ramps, concrete pads, and other structures not directly connected with the building. 5. Foundation Plan Establish a structural grid line pattern. Indicate the foundation walls, cassions, piles, perimeter beams & or footings for all bearing walls and columns. Refer to the architectural drawings for over all building dimensions. Show the dimensions and indicate the material of all foundation structural members. Show reinforcing where applicable. Show the footings and foundations of the building components directly adjacent to outside the building properly. Eg : exterior stairs, ramps, loading dock platforms, concrete pads at entrances , etc. Indicate the unexcavated area Refer to the foundation component details. Note the description of the floor slab and it’s finished elevation. Indicate any changes in the floor slab thickness, elevation and slope. Show all expansion control and perimeter joints and the pit opening to be provided in the floor slab. Check the opening in foundation walls or the floor slabs required by the electrical and mechanical design. Tabulate all footings, walls, slabs, beams and columns, giving the location, dimensions and reinforcement where appropriate. 6. Floor Framing Plans Follow the established structural grid line pattern. Check the architectural drawings to ensure that all walls, posts and or columns are shown and designed on the structural drawings. Check against the mechanical, plumbing and electrical drawings to ensure that all ducts , vents, conduits and other openings are considered in the design and indicated on the structural drawings. Show the dimensions and indicate the material of all structural members. Show reinforcement where applicable.
Indicate the elevation of top of floor (concrete slab, rough wood floor, top of steel as appropriate) and all parts of the floor plan that are depressed or stepped up. Indicate the ceiling bulkheads and the door & window lintels. Provide a tabulated lintel schedule for the given floor given indicating the dimension and material. If the floor framing plan is broken down into two or more parts, the following rules must be observed. Draw all parts with the same orientation. Overlap each part to a point midway between the structural grid lines. Show the overall dimensions for each part. Include a small scale reference showing the location of all parts of the floor framing plan on each sheet. Show all openings in the floor assembly larger than 0.25 m2 in area (eg: stair wells, lights wells, mechanical openings , etc.) Show the concrete curbs at the transformer vaults and oil tank storage room entrances if any. Indicate the floor slope and floor drains where appropriate Show any expansion and/or construction joints. Design the elevator shaft and show that it conforms to the loading and dimensional specification provided by the elevator supplier. Refer to the wall sections and/or details where applicable. 7. Roof Framing Plan Follow the established structural gridline pattern. Show the dimensions and indicate the material of all structural members. Show the reinforcing fastening and/or anchoring of all framing members where applicable. For flat roofs indicate the elevation of the top of roof slab or top of steel and any variations. Show all openings in the roof framing assembly larger than 0.25 m2 in area (eg : stairwells, attic hatches, light wells, mechanical openings, chimneys, gas heater stacks, roof vents) Indicate any skylights and other structures or equipment protruding through or installed above the roof plan.

Indicate the depth below grade at the underside of all footings for the finished grade and floor elevation set by architectural drawings. For the masonry wall indicate the type and spacing of masonry ties.
9. Stair details A floor framing plan at each landing level is desirable.
