Q$.1.$ Commercial Tower Construction layout is as shown below.

$($a$)$ Plan

$($b$)$ Elevation

The project comprises $159$ m high structure with $141$ m high $47$ floor office and residential tower

above $18$ m high three floor podium of commercial space. Dimensions of each floor in the tower

are $36m31m$ and in the commercial centre are $80m35m.$

The Building is in a confined location in a busy urban locality with congested roads as well as

occasional high winds. The structural frame of the building was cast$-$in$-$situ type construction. The

contractor is allowed to use precast elements for exterior finishing of the tower. Construction

progress rate of the building is one floor per week. Overall construction time assigned for the

project is $24$ months.

A$.$ The contractor needs assistance with respect to planning of earthwork traffic

$($during foundation stage$)$ for the site such that operations are carried out

efficiently without disturbing the city traffic and no undue effect of city traffic

on movement of dump trucks to and from the site. Prepare a site layout plan

clearly showing the location of excavator and flow path of dump trucks in the

site. Justify the layout. Can there be any alternative to the excavator dump truck

arrangement.

B$.$ With respect to the tower construction, the contractor has three options

mentioned below for tower crane and concrete pumps. With suitable reasons,

justify which option should be recommended to the contractor.

Options for Selection of Construction Crane and Concrete placement:

With respect to the construction crane draw the site layout diagram clearly

showing the position of the cranes with respect to the buildings. Also enlist

appropriate safety protocols to be followed considering occasional high wind

speeds.
