Consultancy FAQs
Common questions from developers, municipal builders, and institutional property owners.
What differentiates SEMAYI from a conventional architectural firm or general contractor?
SEMAYI operates as an independent building and engineering consultancy. Unlike general contractors who sell physical construction services, our sole fiduciary duty is to protect the client's interests. We provide uncompromised technical oversight, independent quality control, rigorous design coordination, and transparent cost management.
Are SEMAYI's designs compliant with Ethiopian and international building codes?
Yes, absolutely. All engineering designs and calculations strictly adhere to the Ethiopian Building Code Standards (EBCS), the Addis Ababa Municipal Master Plan regulations, and international standards including Eurocodes, ACI (American Concrete Institute), and NFPA life-safety codes.
Can SEMAYI handle both the design and the on-site construction supervision?
Yes. Many of our clients commission SEMAYI for end-to-end consultancy: from initial architectural schematics and structural engineering blueprints, through to full-time Resident Engineer supervision on site until final building handover.
How does SEMAYI assist with municipal permit approvals in Addis Ababa?
We prepare complete, code-compliant permit packages formatted exactly to municipal requirements. Our experienced liaison engineers coordinate directly with sub-city construction permit offices to resolve technical inquiries swiftly, preventing regulatory delays.
How does quantity surveying by SEMAYI protect developers from budget overruns?
Our quantity surveyors prepare detailed, itemized Bills of Quantities (BoQ) with standardized measurement codes. This forces contractors to bid transparently on verified material quantities rather than vague lump sums. During construction, we physically verify on-site work before approving any interim payment certificates.
At what stage should a client engage SEMAYI?
The earlier we are involved, the greater the value we deliver. Engaging SEMAYI before purchasing land or finalizing architectural concepts allows us to perform soil and zoning due diligence, saving developers from expensive unforeseen site conditions.
