TOKYO -- An expert panel set up by Tokyos newly elected governor says the price tag of the 2020 Tokyo Olympics could exceed $30 billion unless drastic cost-cutting measures are taken. Thats more than a four-fold increase from the initial estimate at the time Tokyo was awarded the games in 2013.Following is a breakdown of the panels projected costs by category. Original bid estimates have been included when available.---NATIONAL STADIUMThe building of the new national stadium, which will host the opening and closing ceremonies and track and field, has been plagued by a series of problems. An earlier design by the late Iraqi-British architect Zaha Hadid had risen to $2.65 billion, more than twice the original forecast. The Japanese government decided to scrap that plan and, on Friday, approved a new stadium project totaling nearly $1.5 billion. Officials say construction will begin in December and be completed by November 2019.---OLYMPIC VILLAGELocated on reclaimed land in Tokyo Bay, the panel estimates the cost at $954 million. The village is being built by a private consortium and will be rented during the games. The plan is to transform the village into a residential area after the games.---TEMPORARY VENUESOrganizers plan to build seven temporary venues for sports such as beach volleyball, triathlon and gymnastics. In July, the organizing committee acknowledged the cost of building those venues had surged to an estimated $2.6 billion, up from an initial estimate of $800 million.---PERMANENT VENUESTokyo plans to build seven new permanent venues to go along with 19 existing venues. The panel estimates the cost of the seven new permanent facilities at $2.24 billion. However, it has proposed using existing facilities for three sports -- volleyball, swimming, rowing and canoe sprint -- instead of building new permanent venues. The canoeing venue could move to Tome City in Miyagi prefecture, about 440 kilometers (270 miles) northeast of Tokyo.---SOFT COSTS (security, transportation, operating fees, etc.)Based on estimates from the 2012 London Olympics, the panel suggests these costs could be as much as $16 billion, including $2 billion for transportation, $3 billion for security, $6 billion for energy and technology, and $5 billion for operating costs.---OTHERThe breakdown does not take into consideration unforeseen costs. The panel said these could arise from earthquake prevention measures and the possibility that additional venues may be moved outside of Tokyo, increasing transportation and security costs. Tokyo organizers are also looking at measures to counter the extreme heat in Tokyo and the panel took those potential costs into consideration when it came up with the estimate of $30 billion.---TOTAL COST:Bid estimate: $7.3 billion.Panel estimate: $30 billion.

Carlton will be desperate to give favourite son Andrew Walker the farewell he deserves in Sundays AFL clash at the MCG.Walker announced earlier this week he would retire after tackling St Kilda, with a debilitating knee injury having taken its toll.The 30-year-old will be best remembered by AFL fans for his spectacular mark in 2011.But at Princes Park it is his work ethic and professionalism that coaches will miss most.John Barker, an assistant coach at the Blues for much of Walkers career, says the forward routinely set the standard at pre-season training.I remember hed come back and just win time trial after time trial, after time trial, Barker said.He has a mindset where the off-season is not a time to let the hair down for two months.Its a time to let the body repair, prepare yourself for another solid pre-season .. that has an impact on young players.I know the boys will be really proud if they can get the job done for him and he deserves that sort of performance from us.Barker paid tribute to the fact Walker will finish with 202 games despite a series of setbacks..ddddddddddddHes had a body that has been failing in recent years, he said.But because he was so meticulous with his preparation, it allowed him to keep fighting through and keep being an effective player for us.Hes super quick but has also got a massive tank. He was a team-orientated player but had flashes of brilliance.None more brilliant than that mark, when Walker used Essendon defender Jake Carlisle as a stepladder.I remember the excitement through the box then it just went quiet, it was almost like everyone stopped coaching for about 10 seconds to watch the replay, Barker said.Even without Walkers swansong, the Blues wont be lacking in motivation according to Barker.They have made significant gains during Brendon Boltons first season in charge but must aim to make plenty more in the final four rounds.We want to learn and get better each week. We dont want to get to the end of the year and think - gee, we wasted four weeks, Barker said. ' ' '
