Q1:

Given the following specifications for a pad footing: 2000 x 2000 x 900 PAD N28-200 EACH WAY BOTTOM (a) Calculate the total volume of earthwork or excavated soil (in cu.m.) for six (6) pad footings. Depth of excavation includes the thickness of 150mm slab on grade and 100mm thick blinding concrete. (b) What is the total volume of concrete (in cu.m.) required for blinding concrete for six (6) pad footings? Put only the number in the blank box, without any units. Round up the answer to the nearest whole number.You started this Question 13 have the full am The following is an excerpt from a first floor concrete reinforcement plan for a two-way flat plate. These specifications provide the reinforcement requirements for a 260mm thick suspended slab and at the perimeter edge of the slab. SLAB BOTTOM REINFORCEMENT PROVIDE BOTTOM MAT CONSISTING OF N16-250 EACH WAY. PROVIDE 1000mm RANDOM LAP MINIMUM. SLAB TOP REINFORCEMENT PROVIDE BOTTOM MAT CONSISTING OF N16-200 EACH WAY. PROVIDE 1000mm LAP MINIMUM. LAPS SHALL aNV20 bottom x 800% Long in 3ro Layer NOT BE PLACED WITHIN 1000mm OF ANY COLUMN. 2,000 Where appropriate, put only the number in the blank box, without any units. (a) What is the class and bar size in mm of the typical mat reinforcements of the suspended slab? (b) Why are the typical reinforcements required (c) What is the bar size in mm and length in mm of the additional reinforcements? (d) What is the required number of bars and where are these additional reinforcements placed (e) Why are these additional reinforcements required in that portion of the suspended slabGiven the following specifications for strip footings: 1200 x 750 DEEP STRIP FOOTING PROVIDE 8N16 BOTTOM LONGITUDINAL PROVIDE N16-200 U-BARS BOTTOM WITH 500 VERTICAL COG EACH SIDE Concrete cover from all edges of the footing is 75mm. What is the spacing between the U-bars (in mm)? Round off your answer to a whole number and no decimal places.
