Applying principle to residential low rise construction
Question 1The reinforced concrete ‘slab on ground’ flooring system for the 2 storey dwelling detailed in the plans is to be constructed utilising expanded polystyrene void formers. The site will be excavated to provide a level ‘bench’ incorporating cut and fill. Piers will be required to support the slab on an even foundation. a) Prepare a sketch of the plan view of the slab indicating the possible location of the piers You can assume the piers are 300mm in diameter (Hint: position piers at all comers/beams intersections, then place between these at maximum 1800 centres) b) Provide a section in parts (‘break’ the sketch to show relevant parts of the slab) through the slab from front to back and through the garage, detailing the use of the void formers and the reinforcement. Indicate the foundation and any change in floor level. c) Prepare a typical section through the edge beam of the slab. Clearly show the external wall detail to 300mm above the slab.
Prepare a sketch of the joint between the external wall frames and the first floor joists. Fully label the sketch and provide dimensions and member sizes. Clearly show the fitout of the building on this sketch including: • Ceiling and wall linings • Full external wall detail • Flooring • Skirting boards etc
Prepare a sketch detailing the head flashing over a window in the external wall Clearly label all components and provide sizes of elements where appropriate.
Sketch a full detail of the waterproofing to the shower in the ensuite. A full detail will show all parts of the waterproofing, including wall, floor, floor waste and hob. Include two options for the construction of the shower base: 1. Detail a hob constructed with a brick on edge clearly locating the position of the shower screen on the hob. 2. No hob with the floor level continuous from the bathroom into the shower. Also provide a sketch detailing the waterproofing at the doorway to prevent moisture escaping to adjoining rooms.
