No two demolition scopes cost the same, because the price depends on what is under and inside the structure as much as on what you can see. Knowing the drivers helps you brief a demolition contractor properly and compare quotes on the same basis.
The structure itself
- The type of structure: reinforced concrete, masonry or steel frame, and the number of storeys.
- Whether the demolition is full or partial, and whether the building is attached to others that must stay.
- The extent of boundary walls, kerbs, gates and other elements included in the scope.
Access and surroundings
A structure beside a live road, an occupied building or a sensitive structure is demolished differently from one on an open plot. Surroundings decide the method (for example whether percussive breaking is allowed or an alternative such as wire-saw and hydraulic splitters is needed), the size of the exclusion zone, and how much hoarding and traffic management the site needs.
What is inside the building
- Interior and MEP strip-out ahead of the structural work, sorted by material.
- Hazardous materials found in the pre-demolition survey. Older structures in particular can contain asbestos. If it is found or suspected, work stops, the area is isolated and the engineer is notified, and hazardous waste leaves site only through licensed contractors.
Below-ground work
Foundations, basements and buried services change both the method and the programme. Say whether foundations are to be removed and to what level, whether voids are to be backfilled with compaction records, and whether a utility survey is required before any excavation.
Waste, recycling and reporting
Volume and haulage distance to an approved facility affect cost, and so does what happens to the material. Concrete can be crushed on site for recycling where possible, and rebar cut and separated. If the contract needs a waste log or diversion reporting to the engineer, say so in the brief.
Approvals and documentation
A method statement and risk assessment have to be approved by the consultant, utilities isolated, authority approvals obtained and permits to work issued before work starts. These take time, so the programme should allow for them.
What to send for a quote
- The location and photographs of the structure.
- Structure type, height or number of storeys, and approximate plan area.
- Drawings, if you have them, and any existing survey or hazardous-materials report.
- Whether the scope is full or partial, and whether boundary walls and below-ground removal are included.
- Access constraints: adjacent roads, occupied buildings, sensitive structures.
- Waste and reporting requirements, and the approvals the contract requires.
- The programme and handover date.
One package instead of several
Perimeter hoarding, demolition, clearance and handover are often split across separate subcontractors, and the gaps between them cost time. Bariq Arabia can take them as one package under one contract. Send the items above to Info@bariqsa.com or through the contact page and we respond within 24 hours.
