ALL ROADS CONSTRUCTION
Road closures off the table
In looking at options to construct the elevated guideway, we looked
for the most e昀케cient and least disruptive method. Typically, this
would require us to:
● Close o昀昀 sections of road and build supporting structures beneath
the guideway.
● Build large shoring towers and run a form over the top in the shape
of the section.
● Install steel rebar cages.
● Pour the concrete.
● Wait for the concrete to cure.
For each section this could take around three weeks to build the
towers and form work, then one to three weeks for the concrete to
cure, before lowering the form work and dismantling the towers.
In total, this process could take somewhere in the region of two to
two-and-a-half months for each section. To make this process more
e昀케cient, we recognized we needed to do something di昀昀erent, and the
answer was in Dubai.
