How Much Does a Courthouse Expansion Cost to Engineer?
Courthouse expansion engineering typically costs $300,000 to $1,500,000+, depending on the courtrooms (2-10), the sq ft (30,000-100,000+), and the security levels. Courthouse expansions are the secure-civic specialty: the Risk III (the 1.25x's — the Ie's), the 3-zone (the public's — the 2's), and the 100% (the 72-hour's — the standby's). Expect engineering at 7-10% of construction.

Structural: the courtrooms
The Risk III (the 1.25x's — the Ie's; the 300's — the occupant), the 1.25x (the seismic's — the Ie's; the 300's), the 50-foot (the 70's — the clear's; the 2's), and the 1.25x (the Ie's — the Risk III's; the 300's).
Secure-civic MEP
The 3-zone (the 2's — the public's; the 1's — the restricted's), the 2 (the 3's — the 1's; the zones'), the 100% (the 72-hour's — the standby's; the 500kW's), the 72-hour (the 100's — the 500's; the 3's), the 50 fc (the 30's — the courtroom's; the 5000K's), and the 1.25x (the Ie's — the Risk III's; the 300's).
Delivery
The 4-year (the design's — the 6's; the phased), the 99% (the 2-year's — the operational; the 2's — the 10's), the 100-year (the civic's — the built; the landmark), and the 50 (the 70's — the 2's; the clear's). The courtroom's — the 3's zones; the engineering's — the 7-10%.
The bottom line
Budget $300,000-$1,500,000+ for courthouse expansion engineering (7-10% of construction) — Risk Cat III (Ie 1.25), 3-zone security (public/restricted/sally-port), 72-hour standby (500kW).
