The new Grand Central shopping centre and New Street station remain a busy building site with just ten weeks to go until the big launch but bosses of the project have vowed it will be ready on time.
Although it has remained a fully operation railway station throughout the project, New Street will unveil its completed new look on September 20 while John Lewis and Grand Central will open their doors for business four days later.
On the outside, vast sections of the steel frame have yet to be clad in their finished coat of shiny panels while inside scaffolding remains much in evidence and large parts are boarded up or under wraps.
But there is no panic among those charged with bringing the £750 million development in on time.
A small army of 2,000 extra workers are being drafted in to ensure the deadline is hit - taking the number to almost 3,500.
Network Rail project manager Chris Montgomery and his colleagues from the adjoining Grand Central shopping centre and flagship John Lewis store insisted that all would be well during a tour behind the scenes just over two months ahead of the launch.
"It is five times the size of the concourse at Euston - it is a huge area," said Mr Montgomery.
"As opening day approaches, more and more workers will be coming in, another 2,000 on top of what we have now to make sure it is all ready on September 20. It will be ready."
The giant Grand Central sign is already in place, dominating the concourse and atrium area.
About 1,300 workers are currently on site, swarming all over the building in their distinctive bright orange overalls.
Reporters given a 30-minute tour yesterday saw some staff fitting large panels to the ceiling's steel frame, others installing glass panes around the Grand Central balcony.
Lighting was also going in while, far below, floor tiles were being laid on the vast concourse floor.
The centre's 60 shops, including a giant John Lewis branch, are being fitted out.
The development's central area, flooded with light by the atrium, will be the stellar attraction for visitors.
And it is guaranteed to dazzle those who whiled away their time waiting for trains in the old New Street's dingy concourses or the forlorn Pallasades mall.
New Street will fully open on a Sunday as it is the quietest day for the travelling public.
Staff will have the chance to pick up on any snags before the first Monday morning rush hour.
Grand Central will welcome its first customers the following Thursday to allow a steady build-up towards what will be a busy weekend.
Grand Central development director Richard Brown said about 90 per cent of the shop units were let, many to operators and chains new to Birmingham and the Midlands.
"This has been a long time coming and we're now at the final stage of the journey," he said.
"During these final few months a lot will happen."
