How can value engineering reduce cost and time overrun in construction industry. ?
What are the methods which can be followed to avoid cost and time overrun?
Dear Jean
You can take the earn value method (EVM), It’s one of the most traditional or you can also introduced to lean construction and to the last planner system.
I attach a paper of Earn Value Method (EVM)

Integrated Value Engineering and Risk Management synergestically addresses project management bottlenecks and enables achievement of project objectives along the following project success benchmarks: cost, time, quality and sustainability.
Constructability Audit (which is part of best practice design review ) cumulatively addresses project time and cost overruns vis-a-vis overall project project sustainability.

The fundamental tool is a construction contract that encourages contractor value engineering proposals at an early point in the project delivery process. The Missouri Department of Transportation in the US has a program whereby they ask for "alternative technical concepts" from competing contractors during procurement BEFORE the award of the contract to the low bidder. Each bidder bids its own ATCs and all ATCs are kept confidential. This is literally VE after design completion.
Most so-called VE proposals after award are reactive measures that make the project cheaper to mitigate cost and time overruns.

Value engineering methods apply to many engineering fields, products, and industries.
I had proposed a value management methodology in the context of Product Life cycle management processes.
I believe the techniques are quite general and could apply to construction projects as well.

Normally to avoid time and costs overrun in construction processes a case by case analysis is to be made meaning: one bridge, one solution.
In general terms, to save materials (cost), span by span in situ is the best approach. To save time precast segmental may be a good solution. To save more time in very repetitive multi-span (médium small spans) integer segments may be a solution (but higher material costs). This very short question give a very rough tendency, but to do na adequate job, you should analyse all methods (see my paper in "MULTI SPAN LARGE BRIDGES") and compare the main variables in each.
