A National Development Strategy · Prepared for the Government of the Gabonese Republic

Building the Future of Gabon

Affordable housing, workforce development & industrial growth through advanced construction technology.

Executive Summary

As Gabon diversifies beyond oil, a singular opportunity exists to modernize the construction sector — expanding housing availability, strengthening domestic manufacturing, creating certified skilled employment, and attracting foreign investment through strategic public‑private partnership.

01 · Why Gabon

A nation positioned for long-term growth

Urbanization is outpacing existing housing stock. The nation's development objectives create the opening to adopt modern construction technology — reducing timelines, improving quality, and establishing new domestic industry.

Libreville · Port-Gentil · Franceville · Oyem

Gabon's principal urban centers sit along active growth corridors where housing demand consistently outruns delivery. A construction system that compresses schedules and builds domestic manufacturing capacity converts that pressure into national opportunity.

02 · The Challenge

Current housing & infrastructure constraints

The need calls for smarter construction solutions.

Limited affordable supply

Housing stock trails urban population growth

Rising construction costs

Materials, labor and coordination compound expense

Long delivery schedules

Multiple trades and extended sequencing slow completion

Import dependence

Reliance on foreign construction materials

Limited specialized workforce

Few certified technical career pathways

Environmental exposure

Humidity, termites, mold and severe weather stress traditional builds

Growing maintenance costs

Traditional systems deteriorate and demand ongoing repair

Expanding public demand

Schools, hospitals, government, tourism and industry

Project Delivery Timeline — Illustrative Comparison · Typical Single-Family Residence · Shell Completion
Conventional construction12–18 months
Industrialized · SABS3–4 months

A fraction of the schedule — fewer specialized trades · simplified sequencing · integrated structure, insulation and finish substrate in a single wall system

03 · How Xtrata Can Help — The SABS Building System

Remarkably simple — only two parts

Xtrata’s answer is the Saebi Alternative Building System (SABS), ICC-ES accredited under ESR-1638: an EPS structural core and a fiber-reinforced SABSCRETE™ coating. Together they form a monolithic shell that meets or exceeds the testing protocols and load requirements of the International Code Council (ICC-ES).

04 · Fast & Easy Construction

One system. Four trades. A fraction of the schedule.

SABS replaces framing, sheathing, insulation, interior and exterior finish with a single integrated system — fewer trades to coordinate, lightweight components, small crews, minimal waste.

01

Foam Phase

Lightweight EPS shell shaped and set — walls, floors, roof — by a small crew, no heavy framing.

02

SABSCRETE Phase

The fiber-reinforced coating is applied over the entire structure, creating a monolithic shell.

Savings During Construction
  • Four trades instead of eight to eleven — less labor, less coordination
  • Lightweight components — small crews, no heavy equipment
  • Minimal on-site material waste
  • Faster schedules — lower overhead and financing carry
Savings Across Ownership
  • Dramatically lower cooling loads in a tropical climate
  • Minimal upkeep — no termite treatment, no mold remediation, no rot
  • Disaster resilience reduces insurance exposure and rebuild risk
  • A 200-year service life spreads cost across generations
08 · Why Quality Matters

Affordable should never mean disposable

Poor-quality housing carries hidden costs that compound for decades:

Rising maintenance costs
Moisture intrusion
Structural deterioration
Fire vulnerability
Insect damage
Poor energy efficiency
Short building life cycles
Reduced occupant safety
The objective is not simply to build homes quickly — but to build homes that serve families for generations.

Durable housing lowers lifetime ownership cost while improving safety, comfort, and long-term community resilience.

SABS construction built for generations
09 · The SABS Certification Process

Building more than homes

Advanced construction technology teaches new trades to local members — creating an entirely new skilled-labor category in Gabon’s workforce that becomes the labor force for national delivery. A structured certification program converts construction from temporary labor into professional technical careers — with transferable skills, higher wages, and long-term advancement.

10 · Education Through Certification

A national academy of excellence

A structured training academy becomes Gabon's center for excellence in advanced construction — classroom instruction, practical field training, manufacturing education, quality assurance, safety, engineering fundamentals and certification examinations.

11 · Regional Operations

Technology transfer creates long-term economic value

Rather than importing finished systems, Gabon establishes domestic facilities producing advanced building components locally — reducing import dependence, strengthening industrial capacity.

12 · The Economic Impact

Housing as an economic engine

Housing development is more than constructing homes. Every large-scale residential program stimulates demand across the wider economy simultaneously — and when the building system is manufactured domestically, that value stays in Gabon. More jobs, more construction, more development — across manufacturing, architecture, engineering and design.

A social investment and an economic development strategy — at once.

13 · Proof of Concept · Haiti 2011

We have done this before

"The Rebuilding of Communities" — post-earthquake Haiti. Following the 2010 earthquake, our founder — Dr. Nasser Saebi, master structural engineer and inventor of SABS — authored a complete national rebuilding program for Haiti: rapid housing, local employment, and community development in a Caribbean market facing challenges directly comparable to those of any developing nation. This is not about Haiti — it is proof that the model proposed for Gabon has already been engineered, built and validated.

One "super material." An indefinite life span.

Two completely opposite products sharing their advantages: a core that is lightweight, flexible and highly insulating — a shell that is strong, rigid and impermeable, engineered to take decades of coastal abuse.

Non-Organic Core
Waterproof, nothing to rot, nothing for pests to eat

Wood structures rot, burn, and blow over. Block and concrete structures crumble to the ground during earthquakes. The 2011 program argued these problems could never be solved by variations of antiquated methods — only by a completely new product. Haiti, devastated by both earthquake and hurricanes, was exactly the environment SABS was invented for.

15 · The Consortium Structure

Proven builders, organized to deliver

The Haiti program was delivered through a single turnkey vehicle led by Strata International Group — a structure designed to be replicated with local partners and government.

Technology & Engineering · Arizona, USA

Strata International Group

Founded by Dr. Nasser Saebi, master structural engineer and inventor of SABS. The system spent nearly a decade in development — and within five years of market launch was already deployed in projects across five countries.

Residential Developments Commercial Buildings Schools & Hospitals Water Canals Water Treatment Sewage Environmental & Air Quality

Worker training was built into the delivery model from day one — the consortium consistently hired, trained and supported local professionals on every engagement. For Gabon, this seat at the table is reserved for Gabonese firms and institutions.

16 · The Housing Program

From single homes to whole communities

Complete homes arrived as prepackaged container kits — floor plan, finishes, even furniture — move-in ready in as little as one week. Homes as complete packages: order a floor plan, select finishes, receive the package.

17 · The One Percent Model

Local hands built it. That was the point.

The Haiti program was engineered around one governing ratio: one foreign expatriate for every 100 local workers. Money earned on the rebuild stayed in the country — the same principle that anchors the Gabon workforce strategy.

Proven, not theoretical: the Haiti housing prototype was constructed entirely by local workers with minimal training — pre-labeled components, simple assembly, a complete home erected by a local team in as little as one week.
