Project specific containment systems for critical works

Every SESA system is scoped around the structure, the work happening inside the enclosure, the exposure it will face and the program it has to support. The six areas below cover the work SESA takes on.

Service 01

Scaffold encapsulation

Installation of shrink wrap containment systems over suitable scaffold structures. The film is heat welded, sealed and tensioned to the scaffold to form a controlled work area for the trades operating behind it.

Applications

  • Full building encapsulation
  • Temporary weather protection
  • External workface protection
  • Trade separation
  • Dust and debris control
  • Controlled work areas
  • Protection of unfinished structures
  • Protection of internal trades
  • Temporary site enclosures
Scope boundary. The scaffold itself is generally supplied, designed and installed by the client or a qualified scaffolding contractor. SESA installs the containment system to that structure and is not a scaffolding company.

Service 02

Weather protection and temporary enclosures

Shrink wrap weather protection systems designed to reduce exposure to rain, wind, UV, dust, moisture and general environmental conditions so work can continue in conditions that would otherwise stop it.

Applications

  • Temporary weatherproof work zones
  • Covered access areas
  • Dry internal work environments
  • Temporary roof or wall protection
  • Protection of exposed construction areas
  • Temporary enclosures for maintenance works
  • Protection during shutdowns
  • Protection of stored equipment or materials

Commercial value

  • Reduces weather related downtime
  • Protects critical path activities
  • Allows internal and finishing trades to continue
  • Helps prevent water damage and avoidable rework
  • Protects labour productivity and supports greater program certainty
An honest limit. No enclosure eliminates weather risk entirely. These systems are designed to reduce exposure and support continuity, and the level of protection achievable depends on the structure, the scaffold, the exposure and how the enclosure is scoped.

Service 03

Hazardous work containment

SESA provides containment systems for blasting, coating, remediation and other controlled activities. We work alongside the project's specialist contractors to establish enclosed work zones and improve separation from surrounding areas.

Containment can support work involving

  • Lead based coatings
  • Abrasive blasting
  • Industrial coating removal
  • Painting and recoating
  • Silica generating activities
  • Dust and debris
  • Contaminated work zones
  • Remediation activities
What SESA does and does not do. SESA supplies and installs the containment system. SESA does not perform lead removal, asbestos removal, abrasive blasting, industrial painting, hazardous material remediation, environmental testing, occupational hygiene services or clearance inspections. Those activities are carried out by the project's licensed specialist contractors.
Compliance. A SESA enclosure on its own does not guarantee regulatory or environmental compliance. Final containment requirements remain dependent on the project design, scaffold structure, work method, contaminants, ventilation requirements, environmental controls and client specifications.

Service 04

Asset, plant and equipment protection

Temporary shrink wrap protection installed around plant, machinery, structural components and materials that need to be kept clean, dry and separated from surrounding work.

Typically applied to

  • Plant and machinery
  • Industrial equipment
  • Structural components
  • Construction materials
  • Mechanical equipment
  • Infrastructure components
  • Exposed building elements
  • Items in transport or storage
  • Equipment undergoing maintenance

Purpose

  • Weather, dust and moisture protection
  • Surface protection and temporary storage protection
  • Separation from surrounding work
  • Protection during construction or shutdown activities
Scope boundary. SESA does not provide specialist corrosion engineering or guaranteed long term preservation. Where a project has defined preservation requirements, they should be confirmed for that project before work is agreed.
Service 05

Complex and custom encapsulation

Containment around complex, irregular and difficult to access environments where a standard approach does not apply. Each of these projects is assessed individually before any commitment is given.

Environments

  • Bridges
  • Buildings
  • Vertical shafts
  • High bay structures
  • Elevated work areas
  • Industrial facilities
  • Structural steel
  • Concrete structures
  • Conveyor systems
  • Pipework
  • Exposed infrastructure
  • Internal work zones
  • Live construction environments

What the assessment accounts for

  • Existing scaffold
  • Access points
  • Work sequencing
  • Structure shape
  • Wind exposure
  • Material selection
  • Duration of installation
  • Interface with other trades
  • Ventilation
  • Emergency access
  • Exclusion zones
  • Environmental requirements

Service 06

Temporary industrial protection systems

Project specific temporary shrink wrap structures formed using suitable existing frameworks, scaffold or structural interfaces, for works that need an enclosed environment for a defined period.

Applications

  • Industrial maintenance
  • Shutdown works
  • Temporary equipment protection
  • Maintenance enclosures
  • Sensitive work activities
  • Temporary work areas
  • Weather sensitive construction
  • Internal separation zones
Scope boundary. SESA does not supply engineered scaffold or permanent buildings. These systems are temporary and are built off a supporting structure provided by the project.

Technical

Materials and installation methods

  • UV stabilised shrink wrap film
  • Film thickness generally ranging from approximately 180 microns to 280 microns or more, depending on project requirements
  • Flame retardant film options where specified and available
  • Heat welded seams and sealed joins
  • Tensioned installations
  • Systems suitable for extended exposure where properly scoped
  • Integration with scaffold
  • Integration around structural steel
  • Integration around concrete interfaces
  • Formation of access points
  • Project specific work zones
  • Internal and external applications
What SESA will not claim. SESA does not describe its systems as cyclone proof, storm proof, wind rated, airtight, dustproof or waterproof in every condition, and does not provide structural engineering or certify environmental compliance. Any wind loading, structural or engineering requirement must be assessed for the specific project and may require input from the scaffold designer, principal contractor, engineer or another suitably qualified party.

Not sure which system your project needs?

Describe the structure and the work happening inside the enclosure and you will get a direct assessment of whether containment is the right answer and whether SESA is the right contractor for it.
