Building Construction Questions

Combined footing fundamentals — which statements are correct? Consider the following statements about combined footings for two columns: (a) The footing is proportioned so that the centroid of the supporting area coincides with the centroid of the two column loads. (b) A combined footing may be rectangular or trapezoidal in plan. (c) Rectangular combined footings are used when column loads are equal or the interior column carries the greater load. (d) Trapezoidal combined footings may be provided under any loading without restriction. Which option correctly identifies the true statements?

Door and window openings — what are the vertical sides called? In wall construction, the two vertical sides of a door or window opening that receive the frame are known as:

Brick bonds — identify the bond with alternate courses and a three-quarter bat starter Which bond lays headers and stretchers in alternate courses, with every stretcher course starting with a three-quarter brick bat at the quoin to maintain bond?

Timber pile groups — typical centre-to-centre spacing for design and driving What is a commonly adopted centre-to-centre spacing for timber piles in a group to ensure drivability, load sharing, and reasonable cap size (assume typical pile diameters)?

Retaining and breast walls — purpose of providing weep holes Why are weep holes provided through retaining/breast walls (with proper filters) toward the exposed face?

Hospital/X-ray facility finishes — plaster used for radiation shielding X-ray rooms require wall finishes that attenuate ionizing radiation. Which plaster is commonly specified to improve shielding performance (often used with lead lining or high-density blocks as required)?

Waterproofing admixtures — making ordinary concrete more water resistant Which option correctly identifies materials that are added to fresh concrete as integral waterproofing compounds to reduce permeability (as opposed to paints or surface coatings)?

Soil mechanics — properties of gravels as an aggregate fraction Which consolidated statement about gravels is most appropriate in introductory soil/aggregate classification?

Brick closers — identify the piece cut through the centre of width In brick masonry terminology, what do you call the piece obtained by cutting a brick along the middle of its width so that its length remains equal to a full brick (used to maintain proper bonding at quoin joints)?

Timber roof trusses — standard carpentry joints in a king-post truss Choose the correct combined statement about the typical joints used in a king-post roof truss between its principal members.

Plastering operations — term for working a flat to receive the finishing coat In plasterwork, what is the operation called in which the undercoat is worked and made true, level, and keyed with a float so that it is ready to receive the finishing coat?

Cavity wall design — maximum recommended width of the air cavity In a standard cavity wall (two leaves tied across an air gap), the width of the hollow space between the leaves should not exceed which value for typical building practice?

Stair design guideline — maximum recommended pitch (slope) of a stair What is the usual maximum pitch (angle to the horizontal) recommended for stairs in buildings to ensure comfortable and safe movement?
