Engineered Adaptive Reuse. Preserving Structural Value in Active Sites.
Comprehensive structural rehabilitation, carbon fiber (CFRP) strengthening, commercial tenant renovations, and live MEP modernizations across Ethiopian corporate, institutional, and healthcare properties.
We execute complex structural alterations within occupied commercial towers, institutional hospitals, and residential properties without disrupting ongoing operations or compromising load-bearing integrity. Single-source Grade 1 accountability guarantees clean coordination between structural reinforcement, mechanical re-coring, and architectural finishes across Addis Ababa.
High-tensile composite wraps providing immense shear and flexural structural reinforcement.
Measured axial and seismic load enhancement on existing reinforced concrete columns.
Ground Penetrating Radar scanning locating concealed rebars and post-tension tendons before coring.
Off-hours and weekend phased work maintaining zero disruption to active building tenants.
Comprehensive structural rehabilitation extending commercial building operational viability.
Renovation & Asset Deliverables
Carbon Fiber Wrapping & Structural Reinforcement
Non-invasive structural enhancement for buildings undergoing change of use, extra floor additions, or earthquake code upgrades. We apply multi-ply carbon fiber reinforced polymers (CFRP), steel section jacketing, and structural foundation underpinning.
Commercial Tenant Reconfigurations & Fit-Outs
High-velocity interior remodeling for corporate offices, retail spaces, and specialized healthcare facilities (e.g., our radiation-shielded X-Ray renovation at St. Peter's and clinical suites at ALERT Hospital). We reconfigure floor layouts with acoustic partitions, modern ceilings, and updated finishes.
Building Services Modernization & Re-Coring
Replacing aged, corroded plumbing lines and outdated electrical distribution panels in occupied structures. We plan bypass routing to maintain continuous building services while new systems are commissioned.
Facade Restoration & Preventative Facilities Care
Comprehensive exterior restoration, structural joint resealing, elastomeric roof waterproofing, and ongoing planned maintenance agreements that preserve institutional asset value over decades.
5-Phase Retrofit & Remodeling Protocol
Non-Destructive Structural Survey & GPR Radar Scan
Schmidt hammer rebound tests, ultrasonic pulse velocity, and ground penetrating radar (GPR) to map internal rebar density, concrete strength, and structural flaws.
Retrofit Engineering & Temporary Shoring Design
Structural recalculation of existing dead and live load capacities, followed by engineered propping and temporary load transfer shoring installation.
Dust-Contained Demolition & Concrete Surface Prep
Erection of sealed floor barriers, HEPA air scrubbers, and diamond grinding of concrete surfaces to an open aggregate profile required for composite bonding.
CFRP Application, Steel Jacketing & MEP Overhaul
Application of two-part epoxy saturant, carbon fiber fabric lamination without voids, structural steel plate bolting, and parallel MEP service modernizations.
Fire Protection, Architectural Trim & Commissioning
Application of fire-retardant intumescent plaster over retrofitted structural members, completion of architectural finishes, and structural sign-off.
