becos precast girders are not cast in -site and therefore faster. they also available in standard size.
disadvantage: - require more time to construct compare to precast concrete slab -more on-site labor required - require formwork advantage: -most commonly use -do not require storage for material (e.g. precast concrete slab need place to store)
unlike standard concrete which is in a liquid form and poured were it is needed and formed, precast concrete is molded offsite into the form that is required and then shipped to the site where it will be set into place.
