Two carriers, two contracts and two entry points into the building satisfies most procurement checklists. It does not satisfy physics. If both routes converge into the same duct three kilometers down the road, a single excavator removes both of them.
Verifying genuine diversity means reading the actual route maps, walking the critical sections, and confirming that shared structures such as bridges, culverts and level crossings are identified and accepted before signature.
It is slow work, and it is the most common gap we find when we review site packages assembled by others. Where the market cannot supply a diverse route, the honest answer is to build the missing one into the enabling works, and to price it openly.
