Case Study
At first glance, apartments are defined by walls and finishes. In reality, comfort comes from what you do not see: air movement, power distribution, water, drainage, and gas systems all working together.
For Coffman Apts at 62nd St and Coffman Ave in Indianapolis, TS9Designs delivered a full Mechanical, Electrical, and Plumbing package for a two-story multi-unit layout, designed to be practical for permitting and clear for field execution.
Multi-unit residential projects are coordination-heavy. Every apartment must feel independent and complete, while all systems still perform as one building network.
This project required two-floor coordination across HVAC zoning, electrical distribution, domestic water, sanitary drainage, gas routing, riser diagrams, schedules, and load calculations.
We prepared first- and second-floor lighting and power plans, panel schedules, and a single-line diagram. Everyday loads were accounted for clearly: lighting, kitchen circuits, water heaters, laundry equipment, AC systems, and GFCI/AFCI protection.
The plumbing scope included drainage, domestic water supply, gas supply, and detailed riser diagrams. Field details covered cleanouts, venting, appliance connections, and pipe support locations.
Water heater sizing was tailored by unit type: 36-gallon (1-bedroom), 40-gallon (2-bedroom), and 50-gallon (3-bedroom).
Mechanical plans included equipment schedules, airflow values, duct sizing, supply/exhaust coordination, and load calculations. Multiple air handler and condensing unit configurations were planned to match unit layouts and reduce comfort risk.
TS9Designs delivered a complete MEP package that supported permitting and provided the project team with a clear technical roadmap for execution.
The final plans aligned lighting and power routing, apartment-level electrical needs, plumbing and gas distribution, HVAC placement, and installation details into one coordinated set.
“Great buildings do not just happen on site. They start with clean drawings, smart coordination, and a team that understands how every system affects the next.” — Nadif Bracey, TS9Designs
