The hole cannot be larger than one-third the depth of the joist, so the maximum hole size for a 2×12 joist (actual size 1-1/2 x 11-1/4 in.) is 3-3/4 in. diameter—plenty big enough for running cable! You can drill the holes anywhere along the length of the joist (first photo).

How to correctly position holes in floor joists so they don’t weaken the joist. You can safely drill joists for electrical and plumbing runs without weakening the joists, if you follow the rules. By the DIY experts of The Family Handyman Magazine. Where and how to drill joists for electrical cables or plumbing runs depends on what type of floor framing you have. Keep the hole at least 2 in. from the top and the bottom if it’s a dimensional lumber joist. The hole cannot be larger than one-third the depth of the joist, so the maximum hole size for a 2×12 joist (actual size 1-1/2 x 11-1/4 in.) is 3-3/4 in. diameter—plenty big enough for running cable! You can drill the holes anywhere along the length of the joist (first photo). If you have manufactured I-joists, you can drill holes up to 1-1/2 in. diameter almost anywhere in the web area (the area between the flanges). Just stay 6 in. away from any end or load-bearing wall (second photo). Holes up to 4 in. can be drilled in the middle of the I-joist, away from the ends and load-bearing wall. Keep the distance between adjacent holes at least twice the diameter of the largest hole. For holes larger than 4 in., consult the lumber supplier.

Typically you run joists the short direction for the maximum load bearing capability.
I'm not sure exactly what the orientation of this floor is? It is also common to split the 16 foot span in half with a center carrier beam, thus allowing you to use 8 foot joists on either side. The advantage to using two sets of 8 foot joists as opposed to single longer ones is that you can use smaller less expensive stock, and you can more easily control any wain or bowing typical in longer stock. Using a center beam also gives you a good structure to add additional center concrete post supports. This is also done by running a perpendicular double beam half way under the 16 foot joists, which gives the same support as using two 8 foot joists with a center support.
