I checked and per a Roseburg Forest Products booklet holes up to 2" are permitted as follows:
No more than 3 holes.
Square and rectangular holes are not permitted.
Does not apply for cantilevers.
Hole to be centered on height of beam.
Holes (if more than one) must be a minimum of 4" clear distance between holes.
Hole must be at least 2 1/2 times height of beam away from load bearing point
The weight capacity of a microlam beam depends on its size, span length, and load distribution. It is important to consult a structural engineer to determine the specific weight capacity for your particular application.
Typically, the drilling mud ratio for a sand gravel mix is around 1:1 to 1:2, meaning one part drilling mud to one or two parts sand and gravel. This ratio may vary depending on the specific drilling conditions, equipment used, and desired drilling outcomes. It is important to consult with a drilling mud engineer or supplier to determine the best ratio for your particular situation.
No, laser beams do not have an electric charge. Laser beams are composed of photons, which are neutral particles with no charge.
Beams are structural elements used to support loads and transfer them to supports. They resist bending and torsional forces to maintain the stability and strength of a structure. Beams can be made of various materials such as wood, steel, or concrete to suit different applications.
The hook load capacity is the maximum weight that a drilling rig can lift. The drilling depth is how deep the rig can drill into the ground. The hook load capacity needs to be sufficient to lift the drill string and other equipment needed to reach the desired drilling depth without exceeding the rig's lifting capacity.
MIcrolam is very similar to lumber, but it is much stronger. it is made with the same layering technique, but has more durablilty, and requres less supporting beams. Microlam would be a great choice for a deck.

better try to avoid drilling on concrete beams......!!
Microllam is typically sawed into 1.25 inch wide planks. These planks are made into beams that span up to 16 feet.
As a roof truss/I-joist/beam designer, I can tell you that you should not cut ANY holes in a microlam beam without consulting an I-joist/beam designer first. Microlam beams are not calculated to have holes cut in them. This requires special engineering.Depending on the size of the hole and it's placement, and the load that the beam is carrying you may not be able to cut a hole in it at all. Considering the 25' length (if this is a clear-spanning beam) I can warn you that abeam designer is probably going to tell you to find a different solution for this issue.Hope this helps!
Drilling through structural beams is strictly limited. You must have engineers approval.
Microlam (or glulam) is an engineered timber product that is made from layers or wood held together with adhesives. The end product is generally made into lengths or beams that are stronger and less prone to warping and twisting than standard timber products.
unless you got a great deal on them, it would never make $$$ sense to use a microlam in lieu of a TJI joist or dimensional lumber. . .microlam is too costly if you have them on hand, I would call the manufacturer. . .they should be able to give you the numbers or send you a book with the span charts

Brennan Beams goes by Beams.
Yes, The multiple layers of wood glued together makes them 50x stronger than standard lumber.

Drilling centre and guided drilling get your hole in precisely the correct place.
