Latest Cost Estimates of Building Projects in Nigeria 2018 (Osaz'Index)

Based on popular request, your first choice contractor and construction partner, Engr. Osaz' finally brings you the latest building design and construction cost index valid for towns and cities across Nigeria, sourced from priced bills of quantities/quotes of quite a number of completed and on-going private projects, and based on wide consultations with relevant industry stakeholders especially Contractors, Quantity Surveyors, Builders, Engineers and Architects.

It is important to note that no two projects are exactly the same in scope and extent of work to be done and we hope you also know that we do not reserve the right to determine what fees or bill any contractor or professional handling any project should charge a Client or Project Owner at any time, hence the figures displayed here only serve to guide you so as to make informed decisions. 

This therefore doesn't give any contractor or project handler any particular advantage over the other as sources of estimates for this research remain confidential.  

The cost parameters has been divided into three main categories - Design, Structures & Services and Finishes.

Design - Architectural Drawings, Structural Design, Electrical Services, Mechanical Services Designs and other relevant working drawings.

Structures & Services - Foundation/Substructure works, Columns, beams, stanchions, floors, staircases, Lintel, arch, block/brick wall, steel panel wall systems (where applicable), roof carcass, roof covering, windows, doors, ironmongery, Plumbing and Electrical Installations etc. 

(The rough estimates for Structures & Services is based on the assumption that the parent wall material is made of reinforced concrete, block, brick or steel or a combination of any of them. It is also assumed that a soil test must have being carried out to determine the depth of suitable subsoil for foundation. Plumbing and Electrical installations doesn't include expensive gadgets like AC, Jacuzzi and Bath Cubicles.      

Finishes -Wall Finishes, Floor Finishes, Ceiling Finishes, Fitting, Fixtures and related items of work.

Generally, costs of finishes are largely subjective and differ with individual tastes and preferences, therefore for the purpose of this Index the cost of finishes only represent the cost of regular finishes (i.e. cement-sand rendering, plastering, normal painting, fair quality wall and floor tiles, PVC ceiling or its equivalent etc).  

The rough estimates for External works (e.g. Perimeter fencing, soak-away pit/septic tank. borehole, Interlocks or pavers, beautification, external security furniture, landscaping, etc) are not included anywhere in the list. 

Because of the level of discrepancies observed in construction bills from location to location, handlers to handlers and with differences in designs and site conditions, it was only reasonable to present Osaz'Index in a range value format as seen below.
