Hilton Garden Inn, Al Hofuf

The clearest version of how we work: Green Square is carrying the structure and every system inside it, civil works and full MEP, from foundations to commissioning, with the services model frozen before the first slab was poured.

Who we are

Engineering-led, from the slab to the switchgear

Most buildings fail in their systems, not their structure: a plant room that cannot hold a 50°C afternoon, a riser coordinated too late, a fire system never witnessed. Green Square was built to close those gaps.

So we engineer every system in-house, from district cooling and HV power to NFPA fire, medical gas, ELV, and the concurrently maintainable plant a data hall depends on, modelled before the slab is poured and commissioned against the model. Same standard, in Qatar and Saudi Arabia.

Our commitments

Quality · Innovation · Sustainability · Lifecycle Performance

Civil Construction

Civil, structural, architectural, and infrastructure works, carried from the ground up by crews on our own payroll.

Advanced Building Services

MEP, fire protection, ELV, and the concurrently maintainable plant behind data centres, engineered in-house and commissioned by us.

Sustainability & Innovation

Energy-efficient buildings, digital engineering, and lower lifecycle carbon, designed in from day one.

Quality & Delivery Excellence

Safety, quality, and on-time delivery, held to one audited system on every site we run.

What we do

We build the whole building

Civil, MEP, ELV, mission-critical, outdoor cooling, and interiors: each a licensed trade run by our own engineers, and coordinated in one model before the first slab is poured.

01 / End-to-end building execution

General Contracting

Complete building execution with disciplined project management, structural integrity, and architectural refinement, from enabling works to handover, by crews on our own payroll.

Civil & Structural
Foundations to frame.
Architectural Finishes
The whole envelope, sealed.
External Works
Roads, utilities, landscape.
PM & EPC Integration
One accountable team.

02 / Mechanical, electrical & plumbing

Specialized MEP Works

Advanced mechanical, electrical, and plumbing engineering, built for efficiency, compliance, and lifecycle performance. This is where buildings usually go wrong, so it is the work we keep closest.

HVAC & Cleanrooms
Cooling that holds at 50°C.
Ventilation & Smoke
Life safety you can breathe.
District Cooling
ETS networks, built and run.
Electrical & Power
HV to the last socket.
Plumbing & Drainage
Supply that disappears.
Fire Protection
NFPA throughout.
Fire Alarm
Detection tied into the BMS.
Medical Gas
Hospital-grade, certified.

03 / Smart & connected buildings

ELV Systems

Smart, connected building technologies that carry security, automation, and digital infrastructure. Extra-low voltage is its own trade here, not a line under electrical.

BMS & Automation
One screen for the plant.
Security & Access
Perimeter to door.
ICT & Cabling
The building's backbone.
Guest Rooms (GRMS)
Rooms that know the guest.
AV, IPTV & PA
Screens, signage, and PA.
Lighting Control
Light that follows daylight.
Master Clock
One clock, every system.
Smart Building
Systems that talk to each other.

04 / Facilities that cannot stop

Mission-Critical & Data Centres

Data halls, control rooms, and the plant behind them, engineered to be concurrently maintainable: two paths from the grid to every rack, N+1 cooling that rejects a megawatt into a fifty-degree afternoon, clean-agent suppression, and an integrated systems test on load banks before the first server arrives.

Critical Power
Two paths to every rack.
Precision Cooling
A megawatt, rejected at 50°C.
Data Hall Fit-Out
Racks, floor, and fibre.
Monitoring & IST
Tested at full load, then handed over.

05 / Open-air comfort

Outdoor Cooling

Engineered climate-control solutions for public realms and open-air spaces: terraces, boulevards, paddle courts, and venues that stay usable through a Gulf summer. Modelled in CFD before a duct is laid, and a regional specialty of ours.

CFD Simulation
Comfort you can measure.
Evaporative Cooling
Misting you feel, not see.
Air Displacement
Moving air where people sit.
Outdoor Venues
Terraces, plazas, and venues.

06 / Ready from day one

Interior & Fit-out Solutions

Premium fit-out and bespoke finishes through to FF&E, OS&E, and final installation. Interiors that bring design, craftsmanship, and operational readiness together, ready to welcome people from day one.

Interior Fit-Out
Built to brand standard.
Bespoke Joinery
Made to the drawing.
FF&E & OS&E
Specified, sourced, installed.
Hospitality Interiors
Opening-day ready.

Sectors

Built around your sector

A hotel, a hospital, and a cold store all fail in different ways. We learn what failure means in your building before we design against it.

Hospitality & Leisure

Hotels and resorts, where a bad night's sleep is an engineering fault.

Commercial

Grade A towers that survive an institutional tenant's checklist.

Residential

Towers, villas, and palaces engineered to disappear into daily life.

Corporate Real Estate

Headquarters and workplaces built to say something about their owner.

Healthcare

Hospitals where the building services carry clinical risk.

Pharmaceuticals & Life Science

Cleanrooms and controlled environments, engineered to classification.

Education

Campuses from early-age schools to universities.

Industrial

Factories and plants where downtime is the real cost.

Oil & Gas

From FEED to commissioning in an unforgiving industry.

Energy & Renewables

Power and renewables infrastructure, built to grid standards.

High-Tech

Data centres and facilities for technologies that cannot overheat.

Retail & Malls

Malls and stores that keep trading while we work around them.

Government & Public Sector

Public infrastructure delivered to public scrutiny.

Defense & Special Projects

Specialist facilities, delivered with discretion.

Airports & Aviation

Hub airports that never close while we work.

Transport & Infrastructure

Tunnels, roads, and ports, where ventilation is life safety.

Utilities & District Cooling

District cooling plants, ETS, and networks that serve whole districts.

Projects

Work that holds up under pressure

Eighty-plus deliveries across the Gulf, from World Cup infrastructure to five-star hotels. These are the flagships; the full record is in the gallery.

Why Green Square

Why clients hand us the whole building

Anyone can price a building. These are the reasons clients stop shopping around.

Engineered in-house

Plant selection, BIM coordination, and CFD done by our engineers before the price is fixed.

MEP in-house

Our services trades are on our payroll. The engineers who price your systems commission them.

Safety on record

2.4M+ safe working hours across live sites in the Gulf, and the count is still running.

Dates that hold

The handover date is fixed first and the build is planned backwards from it, so it holds.

District cooling is the Gulf's quietest climate win

District cooling is the Gulf's quietest climate win

Half the electricity in a Gulf building goes to cooling. Districts that share their chilled water are cutting that bill by a third, and freeing entire floors of plant space while they do it.

Commissioning in August: why we test at 50°C on purpose

Any cooling system works in January. We schedule the hard tests for the exact weeks the climate is trying to kill the design, because that's the performance the client actually bought.

The anatomy of a Grade A electrical room

Kahramaa's Grade A classification is the difference between wiring a building and being trusted with serious infrastructure. Here's what the inspectors are actually looking at.

Daniel Okafor · Electrical Engineering Lead

How a project runs

From bare plot to running building

Four stages, engineered before they are priced. The programme is built backwards from your handover date, and we are still there after it.

Stage 01 / 04

Price & plan

Drawings in, priced proposal out, with the programme built backwards from your date.

Stage 02 / 04

Build the structure

Enabling works, substructure, frame, and envelope, delivered by crews we employ.

Stage 03 / 04

Thread the systems

MEP installed by the company that poured the slab, through openings cast in, not cut.

Stage 04 / 04

Hand over and stay

Every system proven and documented, then maintained by the team that built it.

Locations

Where we work

Head office in Al Khobar, delivery teams Kingdom-wide, and an office in Doha behind two decades of delivered work. The same engineers, procedures, and QA files wherever the site is.

Saudi Arabia

The head office sits in Al Khobar and the delivery teams travel, which is how the same crews end up on jobs across the Eastern Province and beyond. MOMAH and SCA classification and Nitaqat Platinum are held here, for public and private sector work alike.
