PropTech sets out to transform built world
8 September 2022
PropTech has become a new buzzword in today’s highly digitalised world. The umbrella term for tech-driven innovative building industry solutions, its adoption is accelerating rapidly – rising by a staggering 1,072 per cent from 2015-19, according to Forbes.
Property technology is only poised to keep growing. A recent study by PwC and the Urban Land Institute highlighted that the use of technologies by real estate companies in Europe will trend upwards over the next three to five years.
Expedited further by the pandemic, property technology is reconfiguring how all stakeholders relate to the built environment, from how they experience, design, construct and market buildings to property management.
Outlined below are some important ways this unfolds across the five property development stages.
Digitalised cities
Data technology is the cornerstone of smart cities. Offering multiple sustainability benefits, it is being used to integrate building and infrastructure systems.
Sensors, data centres and digital twins monitor key historical and real-time indicators of demographic trends, property inventories, power and water use, and building carbon emissions. By using urban data analytics, policies for waste reduction, building decarbonisation and even affordable housing can be better achieved.
A prime example is Singapore’s pioneering digital twin experiment. Data in the form of GIS, lidar and satellite imagery were processed to create a 3D digital replica called ‘Virtual Singapore’.

The single, centralised, real-time database is already helping the city to respond to challenges related to water supply management, track real estate market changes, and deploy solar farms to meet growing domestic and industrial demands.
PropTech adoption accelerated by 1,072 per cent from 2015 to 2019
E-real estate
In the real estate sector, technology is helping to solve problems such as lack of transparency, information asymmetry and high investment risks. In the UAE, a person renting or buying property exclusively through a broker is almost unheard of, while 93 per cent of US buyers use real estate websites when searching for a home. This may mean the entire market is becoming digitalised.
And for very good reasons. For one, online sales platforms simplify the arduous task of property hunting for people with little background knowledge in a sophisticated and highly technical field. Platforms such as Bayut and RealAR app offer in-depth information on listing characteristics, provide analysis of comparable properties, and even furnish virtual simulations to help guide purchase and modification decisions.
But technology is poised to go even further. For example, price-gouging algorithms are being developed to use predictive analytics that process data on transactions, forecast future trends, value property returns and assess mortgage quotations, all aimed at oiling the wheels of a heavy-moving sector.

Building information management
BIM has sounded the death knell for the age of Computer-Aided Design (CAD). Architects and urban designers are now using advanced software to model multi-layered information instead of physical forms. By doing so, integrated design – so crucial for sustainable development – has become business-as-usual.
BIM allows professionals to design, modify and manage the building’s entire lifecycle using a single virtual model that simulates its performance. Further, using parametric tools, designers can even tweak design factors to meet priority sustainability targets.
This is how the National University of Singapore delivered its new School of Design and Environment. Using BIM technology, architects were able to explore options in massing and orientation, canopy and opening sizing, and room layouts by reporting their environment and energy performances in real time.
Optimising these, they passively minimised the building’s baseline energy and material demands. Then, a parity was struck by deploying renewable energy technologies such as 1,225 photovoltaic panels and hybrid cooling systems, allowing the university to pioneer the city’s first net-zero energy building.

3D construction
Technology’s introduction to construction is transforming the sector into a safer, wasteless, cost-effective and faster enterprise. One way this is happening is through innovations in 3D printing machinery. These use BIM models to digitally produce on-site or prefabricated components most efficiently, while complementary smart machinery robotically performs repetitive tasks like concrete pouring and plastering.
One notable example is Dubai Municipality’s largest 3D printed structure in the world, built in 2019. Standing 9 metres tall with an area of 640 square metres, the edifice employed only three workers.

The breakthrough came in constructing the walls by a printer instead of the traditional wooden formwork, steel reinforcement and concrete pouring methods. This was complemented by precast slabs and prefabricated windows, which offered multiple cost and environmental savings.
Nonetheless, the extent of the scalability of 3D printing to multi-story residential and office buildings remains to be explored.
Technology is percolating and reforming every stage of the real estate value chain, from smarter cities to efficient building design, construction, operation and marketing
Green building management
Surprisingly, it has been reported that green-rated buildings can miss their performance and savings targets. According to a recent study, the primary cause is human behaviour. Either uninformed or disincentivised to take full custody of carefully-designed systems, end users frequently misuse them.
But technology has provided the solution: building management systems (BMS), through IoT or digital twins, can track parameters like energy and water usage, waste generation, carbon emissions and indoor air quality, and help to control them.
BMS can even compare performance to design metrics. This is demonstrated by the newly completed Beeah headquarters in the UAE. Acclaimed to be the first fully AI-integrated office in the Middle East, this LEED-certified smart building employs a digital twin as the basis for a Smart Facility Management System.
By learning occupancy habits, one novelty of this system is its ability to forecast energy demands and optimise electricity consumption, conduct predictive maintenance checks, and even take autonomous decisions to rectify faults in equipment performance, achieving a huge 90 per cent energy efficiency saving.

Although a relative laggard in digital transformation, the building sector is swiftly catching up. Technology is percolating and reforming every stage of the real estate value chain, from smarter cities to efficient building design, construction, operation and marketing.
By doing so, PropTech is helping to solve some of the sector’s perennial problems. It is improving information transparency, social inclusion, building design and residents’ wellbeing, in addition to reducing risk and limiting waste generation and carbon emissions, among many other benefits.

EDF eyes 5GW UAE hydropower plant
6 December 2024
Bilateral talks are under way between France’s EDF and Ras Al-Khaimah Municipality for a potential 5GW pumped storage hydropower plant in the UAE northern emirate.
A local media report recently cited EDF Middle East chief executive Luc Koechlin saying the company is in talks with the municipality to set up a 5GW PSH plant, which is likely the biggest in the world.
The project is envisaged to be capable of storing energy for up to 12 hours. It is a country-level initiative aimed at balancing electricity supply in the UAE, where clean energy plays an increasingly significant role in the energy mix.
“Most of the solar farm development is happening in Abu Dhabi and Dubai but for the storage and especially pumped storage, you need mountains,” Koechlin said.
He added that connecting the power grids will help effectively manage energy generated from solar, nuclear and large-scale storage systems.
The UAE and GCC region's first pumped-storage hydroelectric power plant in Hatta is 94.15% complete, and generator installations are under way in preparation for a trial operation in the first quarter of 2025, state utility Dubai Electricity & Water Authority (Dewa) said in November.
The Hatta plant's upper dam, which includes a 72-metre-high main wall and a 37-metre-high side dam, has also been filled. The plant will have a production capacity of 250MW, a storage capacity of 1,500 megawatt-hours and a lifespan of up to 80 years.
The state utility awarded the contract to build the plant to a consortium of Austrian firms Strabag and Andritz and Turkey’s Ozkar in August 2019.
Dewa said on 12 November that the AED1.421bn ($387m) project is expected to be fully completed by the end of the second quarter of 2025.
The hydroelectric power plant is designed as an energy storage facility with a turnaround efficiency of 78.9%.

Oman seeks interest for 2.4GW thermal project
6 December 2024
Oman's Nama Power and Water Procurement Company (Nama PWP) has invited companies to express interest in a competitive tender for the development of combined-cycle gas turbine (CCGT) plants with a total planned capacity of 2,400MW.
The project will be implemented on a build, own and operate (BOO) basis.
The state offtaker said it expects to issue the tender in the first quarter (Q1) of 2025 and award the BOO contract by Q4 of 2025.
It also expects early power in Q2 2028, with full commercial operation set for Q2 2029.
US/India-based Synergy Consulting is the client's financial adviser.
The new project presents a u-turn to a previous decision that Oman will not build any new gas-fired power generation plants, which local media reported in 2022.
A local media report citing Authority for Public Services Regulation (APSR) chairman Mansoor al-Hinai at the time stated that "a decision has been taken that meeting any growth in electricity demand in the future is from renewable sources only".
It was said that Oman will no longer float any tenders other than for solar or wind power generation plants "at this time".
IWPP/IPP extensions
In May, Nama PWP announced the award of renewed contracts for four gas-fired independent power and water projects in the sultanate.
The agreements collectively secure over 1,500MW of electricity and 200,000 cubic metres a day (cm/d) of desalinated water for up to nine years.
The contract renewals follow the expiry or expected expiry of the power- or power and water-purchase agreements for the following plants:
- Barka 1 independent water and power project (IWPP): 427MW (installed power generation capacity) / 101,000 cm/d (desalination capacity)
- Barka 2 IWPP: 703MW / 120,000 cm/d
- Rusail independent power project (IPP): 184MW
- Manah IPP: 179MW

Neom hydrogen project reaches 60% completion rate
6 December 2024
Register for MEED’s 14-day trial access
Construction work on the $8.4bn Neom green hydrogen project in Saudi Arabia has reached a 60% completion rate.
According to a source close to the project, work is ongoing across all three sites, including the wind, solar and green hydrogen production facilities.
At this rate, the project appears on track to meet the company’s 2026 target commercial operation date.
Former Neom Green Hydrogen Company (NGHC) CEO, David Edmondson, told MEED in November last year that “the first ammonia production is expected sometime between mid to late summer of 2026”.
The executive also confirmed at the time that NGHC and its shareholders “are now looking at a potential second phase” of the project.
“The Neom green hydrogen project is not expected to be a single investment,” Edmondson said.
The US-headquartered industrial gases firm Air Products, Saudi utility developer Acwa Power and Public Investment Fund-backed Neom equally own NGHC, the project company implementing the scheme.
In addition to being the project’s co-owner, main engineering, procurement and construction (EPC) contractor and system integrator, Air Products is also the exclusive offtaker for over 30 years for the green ammonia produced at the facility.
The integrated facility will produce hydrogen, which will be synthesised into carbon-free ammonia for exclusive export by Air Products to global markets.
The Neom green hydrogen project will require over 4GW of wind and solar power and 400MW of battery energy storage systems. A 190-kilometre electricity transmission grid will link these to a 2GW electrolysis plant in Neom’s Oxagon industrial city.
The plant will produce up to 600 tonnes of hydrogen daily, which will be converted into about 1.2 million tonnes of ammonia a year.
Construction works have been in full swing for the various elements of the project, after it reached financial close in May 2023.
India’s Larsen & Toubro (L&T) is the EPC contractor for the project’s renewable energy and transmission and distribution package.
L&T’s EPC scope includes a 2,200MW solar plant, a 1,370MW wind farm, a 400MW battery energy storage system and a transmission network extending 190km.
In October last year, NGHC received the first set of wind turbines for one of the two renewable energy plants that will power the integrated green hydrogen and ammonia production facility.
MEED reported in May that Greek contractor Archirodon had won the $100m design-and-build contract for the jetty catering to the project.
The jetty will handle liquid ammonia exports to Europe. The project is expected to be completed in 2025.

Algeria cancels $1.3bn refinery contract and makes new award
6 December 2024
Register for MEED's 14-day trial access
Algerian state energy producer Sonatrach has cancelled its $1.3bn contract with South Korea’s Samsung Engineering for the planned $3.7bn Hassi Messaoud refinery project in Algeria, and replaced it with China’s Sinopec.
Samsung Engineering confirmed the contract’s cancellation on 28 November without specifying the reason.
Sonatrach officially signed the main contract award for the Hassi Messaoud refinery with the consortium of Samsung Engineering and Tecnicas Reunidas in January 2020.
Since then, little progress has been made on the project due to various factors, including the Covid-19 pandemic, which caused significant disruption to the project.
Spanish newspaper CincoDias reported that China’s Sinopec has replaced Samsung Engineering on the project.
Spain’s Tecnicas Reunidas is still participating in the project, according to industry sources.
In August this year, MEED revealed that only some preliminary engineering work had been finished and the project was about 5% complete.
In 2023, Sonatrach restarted talks with the consortium that won the contract to execute the Hassi Messaoud refinery project to get it moving, but they were unsuccessful.
Talks were reinstated in 2024, but these were also unsuccessful.
In August, MEED revealed that Samsung Engineering and Tecnicas Reunidas had asked for amendments to the original deal due to the significant increase in building material prices since the original contracts were signed, which implies the project cannot be completed with the same budget.
At the time, a source said that the consortium wanted more money to account for inflation since 2020, when the contracts were signed.
In July this year, the vice-president of refining and petrochemicals at Sonatrach, Slimane Slimani, said that his company aimed to bring the facility online before the end of 2027.
Industry sources say this target will be difficult to achieve given the extensive delays and disruption that the project has suffered.
Speaking on Radio Algerienne Chaine 3 in July, Slimani said that Sonatrach had officially revived the project, and its execution was aligned with the company’s broader strategy for the country’s downstream sector.
He said the refinery project is estimated to produce an extra 2.7 million tonnes of diesel fuel and 1.2 million tonnes of gasoline a year.
When Sonatrach first announced the project, it was part of Algeria’s $14bn strategic downstream capacity expansion programme, which included the construction of five new refineries.
Under the terms of the original contracts signed in 2020, contractors were required to execute the works on a lump-sum turn-key basis.
Prior to the delays, the work was expected to be completed in about 52 months and conclude in the first quarter of 2025.
The scope of work includes building process and utility units; a crude distillation unit/vacuum distillation unit; a continuous catalytic reforming unit; an isomerisation, naphtha hydro-treating unit; a hydro desulphurisation unit; and a hydrocracker unit, as well as utility systems.
In recent years, Algeria’s $14bn strategic downstream capacity expansion programme has been scaled down and delayed.
Initially, Sonatrach awarded the front-end engineering and design contract for three refineries to London-based Amec Foster Wheeler in 2016.
These three refineries were located in Hassi Messaoud, Biskra and Tiaret.
Under the original $14bn plan, a further two refineries were to be added later.
Budget issues in 2017 put the Biskra refinery on hold so that Sonatrach could focus on moving forward with the Hassi Messaoud and Tiaret refineries.
Then, in 2018, Sonatrach cancelled the tendering process for the Tiaret refinery following a major downstream review.

EDF-led team signs 1.4GW Saudi solar deals
5 December 2024
France's EDF Renewables and its consortium partner, China’s SPIC Huanghe Hydropower Development Company, have signed the power-purchase agreements (PPAs) with the principal buyer, Saudi Power Procurement Company (SPPC), for two solar photovoltaic (PV) projects with a total combined capacity of 1,400MW in Saudi Arabia.
EDF Renewables and SPIC successfully bid for the contracts to develop and operate the 1,000MW Al-Masaa solar independent power producer (IPP) and the 400MW Al-Henakiyah 2 solar IPP projects earlier this year.
The projects are estimated to cost $850m.
The 400MW Al-Henakiyah 2 solar IPP is located 36 kilometres southeast of Al-Henakiyah town in Medina while the 1,000MW Al-Masaa project is located in Dharghat town in Hail province.
The consortium will develop, build, own and operate the projects as part of a 25-year agreement with SPPC.
The signing of the PPAs between Beatrice Buffon, EDF Group vice-president, International Division, and chairwoman and CEO of EDF Renewables, and Mazin Albahkali, SPPC chief executive, coincided with the visit of French President Emmanuel Macron in Riyadh.
In addition to Macron, Saudi Energy Minister Prince Abdulaziz bin Salman Al-Saud, Saudi Commerce Minister Majid bin Abdullah Al-Qasabi, and French Minister of Ecological Transition, Energy, Climate and Risk Prevention, Agnes Pannier-Runacher witnessed the signing of the PPAs.
EDF said once operational, both projects are expected to power more than 240,000 homes a year and displace more than 2.7 million tons of carbon dioxide annually.
The Al-Masaa and Al-Henakiyah solar IPPs were tendered earlier this year under the fifth procurement round of Saudi Arabia's National Renewable Energy Programme (NREP).
