Question 1

Concrete work for thin building elements of specified thickness is usually measured in square metres (area). Which of the following are measured in sq.m under this rule?

Accepted Answer

Introduction / Context: In quantity surveying, the unit of measurement depends on the nature of work. Thin concrete layers or panels of specified thickness are typically measured by area, while structural concrete members (beams, slabs of structural thickness) are measured by volume. Recognizing this distinction is necessary for accurate billing. Given Data / Assumptions: The items listed are thin elements with a stated uniform thickness. Measurement rules prescribe sq.m for such items. Formwork and reinforcement, if any, are measured separately in appropriate units. Concept / Approach: Concrete flooring, thin roof toppings, D.P.C. bands, and thin wall panels are all quantified by area because thickness is standardized in the specification; pricing reflects cost per sq.m for the given thickness and surface finish. Step-by-Step Solution: Roof/floor thin concrete: measured in sq.m at given thickness.D.P.C.: a thin band → measured in sq.m.Wall panels (thin): measured in sq.m.Therefore, “All the above” is correct. Verification / Alternative check: Standard schedules list concrete flooring and D.P.C. items on an area basis, with thickness embedded in the item description. Why Other Options Are Wrong: Any subset misses at least one thin element that is indeed measured by area. Common Pitfalls: Confusing structural RCC slabs (measured in cu.m) with thin toppings/flooring measured in sq.m; not accounting for surface finish requirements in the specification. Final Answer: All the above.

Question 2

For sanitary fittings in a building (e.g., WCs, flushing pipes, lavatory basins, and sinks), the specification and rate typically include the cost of the fittings and their fixing. Which selection best reflects this?

Accepted Answer

Introduction / Context: Sanitary items are generally supplied and fixed (S&F) under BOQ items that include both the cost of the fitting and the labour/materials for fixing it as per specification. This ensures a functional installation without micro-splitting basic operations into separate items. Given Data / Assumptions: Items include water closets, flushing pipes, lavatory basins, and sinks. Standard plumbing practice bundles cost and fixing unless stated otherwise. Ancillary materials (e.g., screws, putty, small sundries) are assumed included in the rate. Concept / Approach: Specification language typically reads “supply and fix in position” for such items, meaning the contractor provides the article, transports, sets it in place, connects as needed, and leaves it ready for use. This bundled approach streamlines tendering and execution. Step-by-Step Solution: Check each item: WC, flushing pipe, basin, sink—all are commonly S&F.Therefore, choose the inclusive option “All the above.” Verification / Alternative check: Reviewing typical SOR entries confirms that sanitary fixtures include fixing, jointing, and making good. Why Other Options Are Wrong: Any single item choice under-represents the standard practice across all listed fittings. Common Pitfalls: Omitting fixing accessories or sealants; misunderstanding when special valves or traps are separately measured. Final Answer: All the above.

Question 3

Under standard measurement rules for building works, to what precision is area typically recorded for billing and take-off purposes?

Accepted Answer

Introduction / Context: Consistency in rounding and recording quantities is essential for transparent billing. Overly coarse rounding introduces significant errors, while overly fine precision complicates documentation without practical benefit. Industry standards specify a sensible precision for area measurements. Given Data / Assumptions: Areas are computed from measured dimensions (usually recorded to 0.01 m). We seek the standard rounding precision for area entries in BOQs. The goal is to balance accuracy and practicality. Concept / Approach: Since linear dimensions are commonly kept to 0.01 m, the resulting areas are reasonably rounded to 0.01 sq.m. This avoids material quantity distortions and aligns with typical SOR/SMM practices. Coarser steps like 0.05 sq.m may cause noticeable discrepancies across many items. Step-by-Step Solution: Recognize standard dimension precision: 0.01 m.Compute area and round: keep 0.01 sq.m for billing entries.Select option 0.01 sq.m. Verification / Alternative check: Checking common measurement handbooks confirms 0.01 sq.m as the norm for area rounding. Why Other Options Are Wrong: Coarser increments (0.02–0.05 sq.m) can cumulatively skew totals and are not standard. Common Pitfalls: Rounding inconsistently across items; rounding intermediate dimensions and the final area separately (double rounding). Final Answer: 0.01 sq.m

Question 4

According to standard productivity norms, what is the expected daily out-turn of cement concrete 1:2:4 (nominal mix) placed by one mason under ordinary site conditions?

Accepted Answer

Introduction / Context: Out-turn norms guide planning and scheduling for concrete works. They depend on mixing method, transport distance, placing constraints, and finishing. For nominal mixes such as 1:2:4, exam-standard planning values are used to avoid over- or under-allocation of labour. Given Data / Assumptions: Cement concrete nominal mix 1:2:4. One mason assisted by helpers under normal conditions. Non-mechanized or basic mechanized handling with typical haul distances. Concept / Approach: Published handbooks and SOR references typically place daily mason output for 1:2:4 concrete around 2.0–3.0 m^3, with 2.5 m^3 as a widely accepted central value for planning. Higher figures assume better mechanization and ideal logistics; lower figures reflect constraints or complex formwork. Step-by-Step Solution: Identify the typical range for manual/semimanual concrete placement.Select a median planning benchmark: 2.5 m^3 per mason per day.Confirm that this value aligns with many question banks and schedule norms. Verification / Alternative check: Cross-checking references shows 2–3 m^3 as common; 2.5 m^3 is therefore a reasonable expected out-turn for exam purposes. Why Other Options Are Wrong: 1.5 m^3 or 1.0 m^3: Too conservative for normal conditions. 3.5 m^3 or 5.0 m^3: Optimistic unless highly mechanized or exceptionally favourable conditions exist. Common Pitfalls: Ignoring delays due to formwork or reinforcement congestion; not considering transport distances or vibration/finishing time. Final Answer: 2.5 m^3

Question 5

In structural steel measurement, which accessory weights are added to the weight of the respective main item for payment and accounting?

Accepted Answer

Introduction / Context: When measuring structural steelwork, standard methods require including the weights of essential accessories that form part of the functional assembly. This avoids underpayment and reflects the true installed steel mass delivered by the fabricator/erector. Given Data / Assumptions: Main members include beams, columns, trusses, and frames. Accessories like cleats, brackets, bolts, and spacers are integral for connections and stability. We seek which accessory weights are included in the payable steel weight. Concept / Approach: Steel measurement conventions typically add the weights of cleats, brackets, bolts, and separators to the respective assembly item because they are necessary to complete the structural connection as per drawings. Minor consumables (welding electrodes, paints) are not weighed but are included in rates by description. Step-by-Step Solution: Cleats and brackets: connection steel → add to item weight.Bolts and separators: essential fasteners/spacers → included in overall steel weight.Therefore, choose “All the above.” Verification / Alternative check: BOQ preambles often state that bolts, nuts, washers, cleats, and small fittings are measured as part of the structural steel item by weight. Why Other Options Are Wrong: Picking any single accessory ignores standard inclusion of all listed items. Common Pitfalls: Double-counting accessories separately; omitting bolts in the final steel tally leading to disputes. Final Answer: All the above.
