Whole-building performanceMore than equipment.
More than equipment.
Networks that work together.
Mechanical systems in construction are the built-in networks that bring a building to life by managing climate control, water flow, power, and safety.
These vital networks include HVAC, electrical, plumbing, and fire protection systems. We coordinate equipment, distribution routes, piping, controls, penetrations, alarms, and service access with the architectural and structural plans—resolving connections early to reduce field conflicts and create cleaner, safer, more maintainable installations.

Core capabilities
Four essential systems.One coordinated scope.
Electrical Systems
Services, distribution, panelboards, lighting, emergency power, generators, EV charging, communications, structured cabling, and equipment connections.
Plumbing Systems
Domestic water, sanitary and storm drainage, natural gas, fixtures, underground services, backflow prevention, sump systems, and process piping.
Fire Protection
Sprinkler and standpipe coordination, fire alarm interfaces, fire pumps, emergency systems, fire stopping, inspections, testing, and life-safety integration.
Controls & Coordination
Coordinated routes, controls, clearances, penetrations, equipment supports, shutdowns, and trade sequencing across every building system.
Testing & Commissioning
System checks, inspections, startup coordination, functional testing, documentation, and performance verification before a clean turnover.
Coordination first
Designed together.Resolved before installation.
Building systems compete for the same ceilings, shafts, rooms, and structural openings. We review routes, elevations, clearances, access, equipment requirements, fire separations, and life-safety interfaces early—then coordinate every trade with the wider construction schedule.

Our approach
A clear path from concept to safe operation
Review
Understand the drawings, building use, constraints and performance goals.
Coordinate
Resolve routes, equipment locations, interfaces and installation sequence.
Build
Caldrin coordinates installation and field supervision. Licensed plumbing and electrical work is performed by appropriately licensed subcontractors managed by Caldrin.
Commission
Test, document and turn over a system ready for operation.
