12. Exterior Building Painting
Exterior painting is not merely a decorative activity.
An exterior coating system can also contribute to surface protection when the substrate is correctly prepared.
DPCON’s external/exterior painting workflow includes:
· Inspection of cracks
· Surface preparation
· Wall cleaning
· Repair of damaged cracks
· Application of crack filler
· Protection of windows and glass
· Primer application
· Exterior paint application
· Removal of scaffolding after completion
The durability of painting work depends heavily on preparation.
If cracks, loose plaster, seepage or other defects are present, these should generally be addressed before final painting.
13. Internal Wall Repair and Painting
Internal walls can develop cracks, peeling paint, uneven surfaces, stains and damage associated with leakage or ageing.
DPCON’s internal painting process includes old paint removal where required, wall crack repair, surface preparation, putty application, primer application and final paint application.
The work can apply to residential areas such as:
· Living rooms
· Bedrooms
· Flats
· Internal walls
· Other occupied spaces
Where dampness or seepage is present, the underlying source should ideally be addressed before decorative repainting.
14. Structural Audit and Building Inspection
A structural audit or technical building assessment can help identify visible deterioration and evaluate the condition of relevant building components.
DPCON’s Architectural and Engineering service categorisation includes activities such as:
· Internal/external survey reports
· Internal leakage and seepage surveys
· NDT structural audit
· Structural audit of buildings
· Building surveys
· Estimation
· Plumbing surveys
· Painting surveys
· Building costing
· BMC survey reports
· Costing and tendering
· Consultation for building restoration
A professional assessment is particularly useful when the extent or cause of deterioration is unclear.
15. NDT – Non-Destructive Testing
Non-Destructive Testing, commonly known as NDT, refers to testing methods used to obtain information about materials or structural elements without unnecessarily damaging them.
Different NDT methods are available for different assessment requirements.
The appropriate tests should be selected by qualified technical professionals according to the purpose of the investigation.
NDT findings can form part of a broader structural assessment, but test results should be interpreted in conjunction with visual observations, available drawings, building history and engineering judgement.
16. Leakage and Seepage Repair
Water leakage and seepage can be particularly difficult because the location where moisture becomes visible may not always be the exact location where water enters.
Potential sources can include:
· Terrace waterproofing
· External walls
· Cracks
· Plumbing lines
· Bathrooms
· Joints
· Rainwater systems
· Other penetrations
A systematic inspection is therefore preferable to simply treating the visible damp patch.
DPCON includes internal leakage and seepage surveys among its engineering-related services.
17. Plumbing Repair
Plumbing defects can contribute to water damage and building deterioration.
DPCON’s plumbing service categorisation includes:
· Internal CPVC or UPVC pipelines
· External pipelines
· Down-take lines
· Loop lines
· Water tank connections
· External PVC pipeline connections
· Bathroom leakage
· Internal connections
· Basin and tap leakage
· WC replacement
· Jet spray replacement
· Tap replacement
Plumbing leakage should be addressed promptly because prolonged moisture exposure can damage finishes and adjacent building components.
18. Core Cutting and Concrete Cutting
Building renovation and modification projects sometimes require controlled openings through concrete or masonry.
DPCON’s core-cutting work categories include:
· Breaking and sawing
· Diamond core cutting
· Groove cutting
· Drilling
· Rebar fixing
· Concrete splitting
· Wire saw cutting
· Floor saw cutting
Core cutting can be required for service penetrations and other approved construction requirements.
Any cutting that could affect structural elements should be properly reviewed and planned before execution.
19. Tile Repair and Replacement
Tiles in bathrooms, kitchens and other areas may require replacement because of damage, renovation requirements, leakage-related work or changes to plumbing.
DPCON’s tile-work process includes activities such as:
· Removal of existing wall or floor finishes
· Reapplication of plaster where required
· Plumbing procedures
· Tile fixing
· Wash basin-related work
· Installation of open fittings
Waterproofing and plumbing conditions should be considered during wet-area renovation rather than focusing only on the visible tile finish.
20. Fabrication Repair and Metal Work
Metal fabrication forms part of many residential and commercial building requirements.
DPCON’s fabrication categories include:
· Window grills
· Doors and shutters
· Safety doors
· Platforms
· Structural metal work
· Loft-related services
The design and material specification should be appropriate for the intended application and loading requirements.
21. Aluminium Work
Aluminium systems are commonly used in windows, doors and internal partitions.
DPCON’s aluminium work categories include:
· Sliding windows
· Openable windows
· Internal aluminium partitions
· Aluminium doors and windows
Maintenance may involve adjustment, replacement of damaged components or more extensive replacement depending on the condition of the installation.
22. POP and False Ceiling Repair
Internal finishing works may also require POP and false-ceiling services.
DPCON’s service categories include:
· False ceilings
· Wall punning
· False ceiling designing
