Rudloff-StrongForce brings post-tension innovation to Islamabad’s tallest residential complex

Rudloff-StrongForce (RSF) is proud to be delivering the post-tension design-and-construct solution for Mount Khalid — a landmark, four-tower residential development set to become Islamabad’s tallest residential complex in Gulberg Greens. Spread over a plot size of 50,000m2+ and rising to 45 levels with more than 1,650 apartments, Mount Khalid combines a striking, mountain-inspired silhouette with panoramic views of the Margalla Hills and an expansive central lake. In total, the project represents over 300,000 m² of built-up area, positioning it as a true city-shaping development for Pakistan’s capital.

While post-tensioned concrete is well established in Pakistan’s bridge and infrastructure sector, its use in high-rise residential buildings is still relatively new. Mount Khalid is helping to change that. As the development gains vertical momentum, RSF’s post-tension systems are being deployed across the four interconnected towers to achieve longer spans, slimmer floor plates and more efficient structural solutions that align with the project’s ambitious architecture. The development will offer premium amenities — including over 40 lifestyle facilities, from dedicated gyms and spas to an artificial lake, jogging and cycling tracks, retail, and business spaces.

RSF has been engaged to provide a full post-tension design-and-construct solution, working closely with the client, Khalid & Khalid Group, and the project’s consulting team. As of Q3 2025, RSF has completed approximately 25% of Tower 4, which represents the largest post-tension scope on the project. This milestone reflects both the productivity of PT construction and the strong collaboration between RSF, the client and the site teams as the structure transitions from substructure to superstructure.

For Khalid & Khalid Group, Mount Khalid is a flagship step into large-scale, luxury real estate — a CDA-approved, investment-grade asset aimed at both local buyers and the global Pakistani diaspora. For RSF, it is a showcase of how international post-tension expertise can be adapted to local conditions and codes to support Pakistan’s next generation of high-rise buildings.

Watch the Q3 2025 project video below to see how Mount Khalid is rising — and how RSF’s post-tension systems are quietly doing the heavy lifting behind this iconic new addition to Islamabad’s skyline.

RSF Spain established with Applus+ national accreditation

Rudloff StrongForce (RSF), a post-tension specialist with a range of EOTA-approved post-tensioning kits, has reached an important milestone in its European expansion with the establishment of a new Spanish entity, Rudloff StrongForce Iberia SL. The registration of RSF in Spain marks a strategic step in supporting clients locally and strengthening our presence in one of Europe’s key infrastructure and construction markets.

In parallel with the new company registration, RSF has obtained the Applus+ Certified Product quality mark from Applus+ Laboratories for its prestressing application systems. This certification has been granted in accordance with SPC 084 Ed. 2 and the Spanish Structural Code, approved by Royal Decree 470/2021, and is officially recognised by the Ministry of Transport and Sustainable Mobility. Achieving this quality mark confirms that RSF’s systems and installation processes meet the technical and regulatory requirements for use on post-tensioning projects throughout Spain.

The Applus+ quality mark provides independent verification that the certified systems are backed by a robust quality-assurance framework. This includes controls over design, materials, manufacture, and installation, as well as requirements for system traceability, competent and trained personnel, and occupational health and safety procedures that go beyond minimum legal obligations. For asset owners, contractors, and designers, it offers confidence that RSF’s solutions align with Spanish structural-concrete regulations and recognised industry best practice.

For RSF, the combination of a local Spanish company and independently certified systems creates a strong platform to deliver post-tension solutions for bridges, buildings, and major infrastructure works across the Iberian market. With technical expertise developed on projects in multiple regions, RSF is well positioned to support complex structural designs, optimise material use, and contribute to efficient, durable construction outcomes.

Rudloff StrongForce looks forward to working closely with Spanish clients, partners, and design teams under the banner of Rudloff StrongForce Iberia SL, bringing together international experience and local compliance – with safety, quality, and technical excellence at the centre of every project.
