In-situ, precast concrete and structural steel for concstruction of low and medium rise framed structures?

What are the advantages and disadvantages of using precast concrete, in-situ concrete and structural steel? Also does anyone know where I could get some more information on this. like a case study or something?

1. Depends on the circumstances. Steel frames can be erected quickly on site but may have long lead time, be inflexible and require secondary fire protection. Prices are currently high. In-situ concrete has some of the disadvantages of steel such as lead times and lack of flexibility (once production starts) but can be quick on site, has in-built fire protection and can have higher thermal mass - helping to regulate building temperature. Precast concrete requires a lot more site work but can more easily accomodate late design changes and irregular frameworks. Its good in fire, has thermal mass and modern formwork systems can increase productivity. Timber framing is also an option for low to medium rise buidings. I've linked some websites of trade bodies which I think have the examples and case studies that you are looking for.
