02 / Installation packages

Installation services organised by project scope.

The packages overlap at system interfaces, but they are not interchangeable. The distinction is the installed system, the components within Cliventa's scope and the coordination required around the wider building programme.

Ventilation Installation

Systems: Project-specified mechanical supply, extract and air-distribution systems for contractor-led building projects.
Components: Fan units, ductwork, supports, grilles, diffusers, terminals and connections where included in scope.
Interfaces: Service routes, access, builders' work openings and coordination with ceilings, electrical and fire-safety packages.

Ductwork Installation

Duct formats: Rectangular, circular / spiral and flat-oval sheet-metal ductwork, subject to the issued design and specification.
Package items: Fittings, branches, risers, supports, grilles, diffusers, terminals and equipment connections where scheduled.
Coordination: Routes through structure and ceiling zones, access for installation and specified fire, acoustic or insulation interfaces.

Commercial Ventilation

Environments: Offices, retail, hospitality, education, cultural, fit-out and mixed-use building projects.
System scope: Supply, extract and air-distribution installation across occupied spaces, service areas and plant interfaces.
Site delivery: Phased installation aligned with access, adjacent trades, live-site constraints and the contractor programme.

MVHR / MEV / PIV

MVHR: Balanced supply and extract through a heat-recovery unit, with distribution ductwork and room terminals.
MEV: Continuous central extract from designated rooms through ductwork connected to a mechanical extract unit.
PIV: Filtered air introduced through a positive-input unit where PIV is specified by the project design.

Mechanical Extract Ventilation

Applications: Specified extract systems for bathrooms, kitchens, utility spaces, back-of-house areas and plant spaces.
Package scope: Extract ductwork, fans, valves, grilles and related connections where included in the project design.
Delivery basis: Installation is reviewed against room use, routes, access, controls interfaces and the agreed package boundary.

Fit-Out Ventilation

Environments: Retail, hospitality, office and other commercial fit-out projects delivered through a contractor-led programme.
Package scope: New distribution routes, alterations, terminals and equipment connections where shown in the issued information.
Coordination: Access, ceiling zones, existing services, phasing and interfaces with adjacent trades are reviewed before mobilisation.

Ventilation Refurbishment & Upgrades

Project type: Alterations, replacements and extensions to existing ventilation installations within a defined refurbishment scope.
Information: Existing-condition details, current drawings, access notes and proposed changes help establish a workable package.
Boundaries: Isolation, controls, commissioning and handover responsibilities are confirmed project by project.

04 / Contractor support

A clear route from RFQ to handover.

The workflow keeps the installation package connected to the drawings, specification, scope and programme supplied by the project team.

01
RFQ / Drawings
The client sends the available drawings, specification, scope, location, programme and tender information.
02
Scope Review
Cliventa reviews package requirements, responsibilities, interfaces and information needed for pricing and planning.
03
Site Installation
Installation is delivered to the agreed drawings, specification, programme requirements and defined scope.
04
Handover Support
Close-out information and handover requirements are supported where included in the agreed package.

05 / Project environments

Built for contractor-led delivery.

Installation support is intended for project and procurement teams delivering defined building packages, rather than private domestic enquiries.
