Project Assignment Bearing capacity $=279$kpa

$2.$ Check the differential settlement to be expected between the column carrying the highest load and the one carrying the lowest load. Check the angular distortion to be within allowable limits$.($Refer to CODUTO CH$2,$ Pages $28-34).$

$3.$ Do the structural design of the intermediate spread footing $(Q_5)$ only and show all the details on scaled drawings of plan, and sections. $($Refer to CERNICA, CH$6).$ Note: Take Live Load as $200$ kN $($included in the column load $Q_5).$

$4.$ Consider a mat foundation instead of square spread footings and determine the allowable bearing capacity using the minimum mat size $($DAS$/$CH$6).$ Check settlement criterion as well, ensuring the differential settlement beneath the mat does not cause angular distortion.

$5.$ Check if the minimum mat size is safe in carrying the given loads.

$6.$ Do a complete structural design. $f_c^{\text{'}}=21$MPa,$f_y=400$MPa, columns: $5050cm$

$7.$ Comment on your results. Which foundation type $($spread or mat$)$ is safer to use for the given conditions. Is it also an economic design?

You can make reasonable assumptions, if necessarv, in accomplishing these steps.
