Project, cost, progress claim and contract
Architecture and engineering offices: design, permits and construction supervision, with staged fees and teams spread across several projects at once.
Owners’ associations in compounds and towers: an annual charge per unit, shared facilities to maintain, and a budget the owners approve.
Contracting firms with long projects, milestone claims, subcontractors, and materials and labour on site.
Air-conditioning and ventilation firms: preventive maintenance contracts, summer emergency callouts, unit installation and parts that change with the model.
Managers acting for property owners: leases, rent collection, maintenance and periodic owner settlements.
Firms hiring machinery and tools to contractors and individuals — scaffolding, generators, mixers, lifts — by the day or the month, with a bond and servicing between hires.
Brokerages with property listings, viewings and commissions, competing for both the client and the listing.
Solar system contractors, from site survey and load calculation through supply, installation, connection and a warranty that runs for years.
