typically, bids are broken down into two components,technical and financial.  First, the technical bids are reviewed by technical authorities to to determine which bids are technically compliant.  Normally, the people reviewing the technical bids do not get to see the financial bids to ensure fairness.  After technical bids are reviewed, only technially compliant bids are assessed (by different people) on bid price.  The lowest priced, technically compliant bid is offered contract.  Sometimes there are exceptions built in so "low price" doesn't necessarily win as additional weight can be awarded to different things (ie best "value" for money) as part of a pre-determined financial evaluation process.
