DUBAI, June 24 (Reuters) - The cost of construction materials in Qatar is likely to jump as the host nation intensifies infrastructure building ahead of the 2022 World Cup, and other building projects could finish late as a result, industry experts say.
Qatar is set to spend more than $200 billion on the soccer tournament as part of a 2030 development plan, although tough contract terms and state bureaucracy have left some contractors in difficulties.
