Cost breakdown
This breakdown reflects the cost distribution typically found in similar construction tenders.
Core matters required for the build such as ground works, steelwork, foundations, blockwork/brickwork, Portaloo hire, skip hire, scaffolding, and plastering.
Internal matters such as partition walls, plumbing, and mechanical and electrical works.
Installation of kitchens, sanitaryware, carpentry, doors, and tiling. Build costs typically don’t include the products themselves because it’s up to the customer to choose what they want.
Generally build costs include the creation of openings for windows and doors, but do not include the supply of windows and doors themselves. This is because the cost can differ vastly depending on customer preference. Skylights (e.g. Velux windows) are an exception to this rule; builders typically include them in their tenders.
Includes various smaller costs that arise during the project, such as final cleanup, temporary structures, and minor adjustments to meet the customer’s specific requirements.
