Plan the work
Heating and cooling load inputs and system zoning. Ventilation and exhaust requirements for the actual use.
Mechanical + HVAC engineering
Design comfort, ventilation, and access as one system.
PRM develops mechanical systems around building use, occupancy, operating hours, equipment needs, and maintenance. Heating, cooling, ventilation, exhaust, and controls are coordinated with the spaces and structures they serve.
“
Clear scope, coordinated information, and accountable decisions from planning through delivery.
What PRM brings
What to bring to the first conversation.
Coordinate the details
HVAC plans, ductwork and piping layouts, and details. Exhaust, makeup air, and equipment-specific interfaces.
Carry it through
Mechanical schedules, diagrams, and design documentation. Submittal and substitution review for design compatibility.
Loads, system selection + operating requirements
Mechanical planning starts with the thermal and ventilation demands of the building, including envelope assumptions, occupancy, internal loads, and special processes. System alternatives are considered alongside available utilities, replacement access, equipment location, and owner priorities.
- Heating and cooling load inputs and system zoning
- Ventilation and exhaust requirements for the actual use
- Equipment selection, schedules, and service-clearance planning
- Energy-performance and operational considerations
Air distribution, piping + controls
Routing is coordinated through the same ceiling, shaft, roof, and plant-room space used by other disciplines. The design addresses air paths, duct and piping distribution, condensate, insulation, noise-sensitive spaces, and the controls needed to operate the intended system.
- HVAC plans, ductwork and piping layouts, and details
- Exhaust, makeup air, and equipment-specific interfaces
- Controls narratives and sequences appropriate to the scope
- Structural supports, penetrations, electrical loads, and access coordination
Installation review + operational handover
Equipment substitutions and field changes can affect loads, controls, electrical requirements, and clearances. PRM carries those interfaces through submittal review, RFIs, and revision control. Testing, balancing, commissioning, and startup responsibilities are coordinated with the project team.
- Mechanical schedules, diagrams, and design documentation
- Submittal and substitution review for design compatibility
- Coordination of testing, balancing, and startup information
- Operations and maintenance requirements for handover
Working relationship
What to bring to the first conversation.
PRM tailors the deliverables, participating disciplines, and level of support to the assignment. Share what is available; the team will identify missing inputs, confirm responsibilities, and define the next useful milestone.
- Floor plans, occupancy, operating hours, and envelope information
- Existing equipment records and utility availability
- Special ventilation, process, kitchen, or comfort requirements
Common questions
Define the next step.
Can this service be part of a broader PRM assignment?
Yes. PRM can coordinate this scope with the other architecture, engineering, BIM, and construction services required for the project. The proposal identifies the included deliverables, responsibilities, assumptions, and milestones.
What if the project is already in progress?
Send the current drawings, open issues, review comments, and immediate deadline. PRM will first assess the available information and define a practical scope for joining the work.
Bring the real constraint
Let’s define what the project needs next.
Share the location, current documents, target milestone, and the decision that cannot slip.
