HVAC & Ventilation
Air distribution, exhaust, ventilation and equipment layouts developed around occupancy and space constraints.
Mechanical Scope
Comfort, water and equipment—designed together.
Mechanical design is more than selecting equipment. Air quantities, heating and cooling loads, shaft space, ceiling coordination, drainage routes, controls and electrical requirements all influence the final solution.
The scope is tailored to the building and project stage, from an existing-system assessment or tenant fit-out to a coordinated permit and construction package.
Heating & Cooling
Load-based system concepts, equipment selection and hydronic arrangements suited to the project.
Plumbing & Drainage
Domestic water, sanitary, storm and fixture requirements coordinated with the architectural plan.
Controls & Interfaces
Controls intent and equipment interfaces coordinated with power, fire alarm and building operation.
Core mechanical workstreams.
Not every project needs every workstream. The study and design scope is assembled around the actual building, applicable approvals and expected construction deliverables.
HVAC and ventilation design
System concepts, outdoor-air and exhaust requirements, air distribution, terminal devices, equipment schedules and coordinated layouts.
Heating and cooling loads
Design inputs and load calculations used to inform equipment capacity, zoning and the selected system approach.
Plumbing and drainage
Domestic water, sanitary and storm drainage concepts, fixture connections, risers and routing coordinated with structure and architecture.
Hydronic and equipment rooms
Pumps, piping, valves, clearances and equipment layouts planned for installation, operation and future service access.
Existing-building upgrades
Field review, capacity assessment and replacement planning for aging equipment, comfort issues and renovation-driven changes.
Controls and sequence intent
Operational intent and key control interfaces documented so mechanical equipment, electrical systems and building operation remain aligned.
A practical delivery sequence.
The mechanical work is coordinated through the same project milestones as the electrical scope, giving the team clearer decisions and fewer late-stage interface conflicts.
Existing conditions and brief
Available drawings, site conditions, occupancy, operational issues and owner priorities are reviewed.
Basis of design
System options, design criteria, preliminary loads and major space requirements are established.
Detailed design
Layouts, schedules, risers and interfaces are coordinated with architecture and electrical requirements.
Permit and construction
Documentation, review responses, tender clarification and construction-phase coordination support delivery.
ETEM coordinates the project workflow and brings together appropriately qualified electrical and mechanical professionals for the required scope. Discipline-specific deliverables are prepared and reviewed by the appropriate professionals.
