Determine the site in which you wish to install the lam beam. Reference the building code for your particular area. Every building code will supply specific information regarding maximum spans, support frequency, as well as maximum weight-bearing loads that will be applied over them. If the building code is not followed, your structure will not be able to be approved and will need to be torn down.
Mark and measure the two end points where you plan to install the lam beam. For example, if you wish to install this beam over the opening to a garage, you will need to measure and have your beam cut to the length between the two columns you will be mounting it to.
Cut four 2-inch by 6-inch planks to the height you wish to support the beam. These will be used as trimmer studs -- two on either side of the span where the beam meets the king studs of the columns you will butt the ends of the lam beam against.
Mount the 2 trimmer studs on either side of the span to the king studs or columns by screwing the first into the king stud, then the second into the first trimmer stud. Do this on the other side of the span as well.
Hoist the lam beam onto the trimmer studs and secure in place using steel ties that will bolt into the lam beam as well as the trimmer and king studs. Steel ties are simply flat metal plates with pre-drilled bolt holes that help to fasten two pieces together.
Build above the lam beam using it as a support for upper floors or just a ceiling.
