SAO PAULO, Brazil -- A safety engineer at the World Cup stadium where a giant crane collapse killed two workers allegedly warned his supervisor of possible problems with the operation, only to have his concerns brushed aside, a labour union leader charged Thursday, as sniping over the accident heated up. The incident has fed worries about Brazils capacity to host next years showcase tournament, as well as the 2016 Olympics, though authorities insist they will be ready for both. Sao Paulos Arena Corinthians was slated to be completed by the end of December, and workers have suggested that speed was a top priority on the construction site, with many working 12-hour shifts and skipping vacations. The stadium was initially scheduled to be part of the Confederations Cup earlier this year, but world footballs governing body FIFA scrapped the venue from the warm-up tournament because of financing problems before construction even started. Antonio de Sousa Ramalho, president of Sao Paulos civil industry workers association, told The Associated Press in a phone interview that supervisors pressed ahead with the operation to finish the roof despite several rainy days that soaked the soil. He said the engineer warned his supervisor that it appeared the ground was not stable enough to support the 500-ton piece of roofing. "To his surprise, he was told by the supervisor that nothing was wrong and work should continue," said Ramalho, who declined to provide the workers name for fear of possible reprisals. "They discussed the matter for a while but in the end the supervisors decision stood." Odebrecht, the powerful Brazilian construction company behind the stadium project and three other World Cup venues, strongly denied the claims, and a civil defence official said an initial inspection of the construction site a day after the accident showed no evidence the ground was unstable. "Odebrecht and Sport Club Corinthians clarify that there was no warning previous to the accident," the statement said. The company added that Ramalhos union does not represent most of the workers involved in the crane operation. Following a visit to the site Thursday, the civil defence official in charge of the inspection said there were no obvious signs that the ground was unstable. "When we looked at it, it didnt seem like the ground shifted, maybe just a few millimeters," Jair Paca de Lima said in a television interview. "Maybe after an analysis with the equipment we will know more." According to Brazilian media reports, investigators are also looking into human or mechanical error as possible reasons for the collapse. Lima said only the area where the accident happened will remain closed, but work can resume at most of the stadium as soon as Monday, when a three-day mourning period ends. Constructors will be allowed to clear the crane and the metal structure after getting clearance from civil defence authorities, which is expected to happen soon. The labour ministry later Thursday said constructors were prohibited from using the other nine cranes at the site until they can show "safety measures are in place and there is no more risk of accidents." Ramalho, the union leader, said workers had been pulling long hours for quite some time in an effort to get the stadium completed on time, a point confirmed Thursday by loader Sergio Almeida, who told the AP typical shifts were 12 to 13 hours long. Besides the Sao Paulo stadium, Odebrecht was involved in construction of the Fonte Nova stadium in Salvador and the Arena Pernambuco in Recife, both of which were delivered for this years Confederations Cup. It also renovated Rio de Janeiros Maracana Stadium, which will host the World Cup final. A small part of the roof at Arena Fonte Nova collapsed in May from weight of accumulated water from heavy rainstorm. At the time, officials denied any structural problems with the project and blamed a mistake by a worker who inspected the roof. FIFA said earlier Thursday it was waiting to learn more about the extent of the damage from Wednesdays accident. FIFA officials and other global soccer personalities are due in Brazil next week for the high-profile World Cup draw in the resort city of Costa do Sauipe. FIFA leaders have said repeatedly that there is no Plan B for next years tournament -- particularly since nearly 1 million tickets to the matches have already been sold. "It is too premature to make any detailed assessment on the situation of the Corinthians Arena as we are still awaiting the technical report to be able to evaluate the scale of the damage," FIFA said in a statement sent to The Associated Press. "We will be able to provide an update earliest next week following the FIFA Organizing Committee of the FIFA World Cup." Jose Maria Marin, the president of the local World Cup organizing committee, said he lamented the accident but was confident it would not significantly affect the opener in Sao Paulo on June 12. "Im certain that the stadium will be ready for the start of the World Cup," he told Brazilian media.

"Ive told you guys a million times, I almost get a bigger joy out of seeing other guys score than scoring myself," he said after putting away the winner at 1:42 of overtime to beat the Colorado Avalanche 5-4. Earlier, he set up Andrew Ladds second goal of the night and Eric Tangradis second goal of the season. In all, Wheeler finished the night with his 35th assist and team-leading 24th goal, cementing his position as the Jets scoring leader with 59 points. Evander Kane also scored for Winnipeg. It was a big night for the Jets as well (32-30-9), as they claimed a little more ground in their uphill climb to the playoffs. They still sit two points behind Dallas and four points behind Phoenix, which now holds the eighth and final wild-card berth. For Colorado (44-20-6), the loss let the Chicago Blackhawks move past them and claim sole possession of second spot in the Central Division after a 4-0 win over the St. Louis Blues. Winnipegs playoff hopes remain a longshot, given the teams it will face as it closes out the season, but it was a big lift nonetheless to take the season series against Colorado 3-2. "It was a big win for us, especially for the goals we gave up," said Ladd. "Were not that bad of a team. Weve played some good hockey of late and we havent got the results." As for his own game, it was also a good night with his 20th and 21st goals of the season. "First one, we had good transition out of our end and I got the puck and a little space and got a good shot off. And the second one, Wheels made a great play driving down and I found some open space and put the puck on the net again." Colorado coach Patrick Roy gave Wheeler credit for his patience in holding the puck and waiting for the right moment to score the winner. "Both teams had good chances," said Roy after his second loss in a row. His homecoming to Montreal ended in a 6-3 loss to the Canadiens Tuesday night.dddddddddddd "At the end they made a great play. Wheeler I thought made a really good play and scored a nice goal." It was the fourth time out of the five games theyve played this season that the Jets and Avalanche couldnt settle it in regulation time. Ryan OReilly, Gabriel Landeskog, Nick Holden and Cody McLeod scored for Colorado. It also was rookie goaltender Reto Berras first start since he was acquired by Colorado from the Calgary Flames at the trade deadline. Landeskog said Berra deserved credit. "I think he made some huge saves in the third when we really needed it the most," said Landeskog, who scored the tying goal for Colorado at the end of the first period to make it 2-2. "I remember my first game with Colorado, certainly a lot of nerves." It didnt help Winnipegs chances that defenceman Zach Bogosian joined the lengthy scratch list, which already included Dustin Byfuglien and goaltender Ondrej Pavelec, who are listed as day to day. Replacement Paul Postma was grabbing a cup of coffee when he got word he had to play. He responded with two assists, including one on Wheelers overtime goal. "Its not too hard to get pumped up in front of this crowd," he said. The Avalanche had their own no-shows as Paul Stastny was out after playing in Montreal on Tuesday following a four-game absence due to injury. They also lost forward John Mitchell in Montreal. But injuries and tough schedules arent uncommon at this time of year and no one was using them as an excuse. "Every teams playing a tough schedule right now and March and Aprils going to be tough for everybody," said Landeskog. Notes: Despite the disparity in their NHL rankings, the Jets and Avalanche went into Wednesdays game with two wins each in their season series, although Colorado had the only win in regulation time. Even the regulation win was decided by one goal. ' ' '
