Mechanical · Plumbing · Fire Protection
Engineering Hawaiʻi's buildings, one permit at a time.
LOFTE Engineers is a licensed mechanical engineering firm on Oʻahu, providing mechanical, plumbing, and fire-protection design for restaurants, residential high-rises, hotels, affordable housing, and homes. We exist to turn a building owner's problem — a permit, a violation, an ordinance deadline, or failed equipment — into a stamped, permit-ready solution.
Our work comes largely through referrals and repeat relationships. That's a mandate: be responsive, be permit-savvy, and make every general contractor, architect, and property manager glad they recommended us.
The firm is led by two licensed principal mechanical engineers, supported by in-house mechanical design — so the person who stamps your drawings is the person who understands your building.
