EXPERTS have been hired to comb Liverpool's 42-acre Paradise Street re-development area for unexploded bombs.
The area was hit hard by German bombers during the 1941 Blitz when the port of Liverpool was a key target for the Luftwaffe.
Many parts of the re-development area have not been disturbed since the massive air raids on the city more than 60 years ago.
Architects and planners compiling a building programme for the £800m development have already held meetings with Government health and safety experts to discuss a UXB (unexploded bomb) strategy for the scheme.
Private companies specialising in ordnance detection have carried out provisional tests using modern techniques and have so far not detected any explosives.
But the real test will come in October when thousands of tonnes of materials will be excavated, with some work going deep into the ground to reach bedrock level.
Last night, Terry Davenport of BDP, the project architects, said: "Because the area was heavily bombed during World War II there are special procedures we have to put into place. Some parts of the Paradise Street site have been built upon, but some sites have been vacant since the war. Some parts of this area were flattened during the Blitz.
"There will have to be detailed inspections in advance of building work before any excavations take place. Fortunately much of this work can be done in advance using specialist equipment."
Contractors will also be alerted to be on the look out for any suspicious objects as they start what will be a massive earth moving operation around Chavasse Park.
The city's old Customs House stood on the site and was destroyed in the bombing along with dozens of other buildings.
Added Mr Davenport: "So far there have been no significant finds, but the area was so heavily bombed that we cannot take any chances."
If any unexploded devices are spotted it is likely that Army UXB teams will be drafted in to tackle them.
