Capital City Towers Moscow

"As a pioneering project in Moscow, Capital City has forged many new pathways for the city's real estate and construction industries. Through its integrated design and engineering, the project provides a model for mixed-use development, which remains rare in the city, and further establishes a new identity for Moscow."

Capital City Towers
After more than a decade in planning, Moscow City, a new mixed-use business district 4 kilometers (2.5 miles) west of the Kremlin, is a symbol of Russia's ascent in the global economic playing field. The capital city mixed-use development (see Figure 1), completed in 2010, is the fourth to be realized among 20 projects which comprise Moscow City, at 302 meters (989 feet) in height, it is currently the tallest building in Europe. With its iconic form that recalls Constructivist geometries, Capital City also captures modern Moscow. It's slender, yet bold residential towers, joined by an office and retail base, are international in quality and performance but still rooted in Russian culture.

With its compressed schedule, achieving this unique structure at this point in Moscow's history required innovation and collaboration. The design introduced advanced engineering and capabilities while building upon local construction expertise. Developed by Capital Group, a Moscow-based company responsible for more than 5 million square meters (53.8 million square feet) of residential, commercial and mixed-use development, Capital City's completion represents an exchange of highrise design and construction expertise that will influence future construction and building standards in Russia.

Anchoring A New District

Moscow's historic center
Capital City's mix of residential, office and retail distinguishes Moscow City from precedents like Canary Wharf in London and La Dèfense in Paris, which were planned primarily as commercial districts and are only now working to increase their residential components. Set on the Presnenskaya embankment overlooking the Moscow River, Moscow City was envisioned from the outset as a place for business, living and leisure. More than 3 million square meters (32.6 million square feet) of residential, office, hospitality and entertainment uses - including Capital City's 288,000 square meters (3.1 million square feet) - are planned for the 60-hectare (247-acre) district. Similar to London and Paris, Moscow City is intended to provide a vitalizing expansion of commercial office space while preserving the character of Moscow's historic center.

The idea of a new business district in Moscow first emerged after the completion of the Expocenter in 1980. With the Expocenter drawing new activity to the area, attention turned to the adjacent site, then a declining industrial area. By 1990, a master plan for a new international business center was in place, but it would take the sustained economic growth of the past decade to finally catalyze developments.

luxury residences
The plan organizes 20 development plots around a central core serving the entire district. Currently, under construction, the central core includes a hotel, retail-entertainment complex and concert hall. Below grade, a retail mall, vehicle access, 2,750 parking spaces, a multi-modal transit hub, and pedestrian walkways will link the central core with surrounding developments and the city beyond. In addition to the completed mini-metro link to the main metro system, future plans include two new metro stations and a high-speed rail connection to the Vnukovo and Sheremetyevo airports.

The luxury residences that comprise the bulk of Capital City's program are contained within the 76-story, 302-meter (989-foot) Moscow Tower and the 65-story, 257-meter (843-foot) St. Petersburg Tower. Both are joined through their first 18 floors by a podium building (see figure 2), creating the larger floor plate desired by commercial office tenants. A "lifestyle marketplace," a fitness spa with indoor pool, and residential lobbies occupy the first three floors.

Together with the two other completed mixed-use towers - the Naberezhnaya Tower (completed 2007) and Imperia Tower (completed 2010) - Capital City provides a firm anchor for the nascent Moscow City.

Collaborative Process

highrise housing
While any project of this complexity requires collaboration, fulfilling the vision for Capital City on a fast-track schedule in a district with few architectural precedents requires collaboration, fulfilling the vision for Capital City on a fast-track schedule in a district with few architectural precedents required extreme agility and innovation on the part of the project team, which spanned 11 time zones from Seattle, to London, to Moscow.

Another complication was the absence of applicable local building codes. When the development of Moscow City Began, local building codes dated back to 1950, when the average building height did not exceed 75 meters (246 feet) and codes for highrise housing did not exist. In order to address the structural and life-safety requirements for Moscow City's tall buildings, rigorous codes modeled after British standards were adopted for all projects in the new district, including Capital City. These codes establish high standards for fire safety, and include 4-hour structural fire resistance, the use of 30-minute fire-rated glass, ample refuge areas, redundant fire elevators and exit stairs, and rooftop platforms for lightweight refuge cabins that can be delivered by helicopter.

To begin construction on schedule, NBBJ and Arup elected to complete the structural design while the architectural design was still in process. The superstructure and raft foundation design was developed on a fast-track schedule that was locked in place after early design development, allowing architectural façade design to continue while detailed structural design was completed. Refuge floor locations in the two tall towers were finalized along with the vertical mechanical and fire separations to allow structural design of the superstructure to be coordinated quickly with the design of the structural out-riggers and core.

After working closely together to develop highly efficient and integrated structural and mechanical systems, the design team worked with Moscow authorities to verify that the project would fulfill the new building codes. Expert panels in structural engineering and life-safety reviewed the proposed design.

Design Concept

Capital City's bold architectural form takes as its conceptual inspiration "Corner Counter Relief" of 1914 by Vladimir Tatlin, often heralded as the father of Russian Constructivism. Tatlin's experimental work in the early 20th century marked an attempt to redefine sculpture's relationship to build space. Slung between two perpendicular walls, Corner Counter Relief breaches the orthogonal shape of a typical room in order to introduce a taut, interstitial geometry. A similar effect is created by the offset rotation of Capital City's tower segments which Level 18 with lower floors also performing as continuous concrete diaphragms.

Foundation Construction

Foundation Construction
The ready availability and local production of concrete, coupled with a local building industry skilled in its use, gave reinforced concrete construction a significant advantage over other options. From an engineering and design perspective, it also allowed for minimal floor depth, maximum fire resistance, and adequate acoustic separation necessary in residential multi-story buildings.

Despite the common use of reinforced concrete in the region, critical portions of Capital City's concrete construction work were carried out in conditions that were nothing but typical. The tower pile caps were installed during continuous, 33-hour mid-winter pours in temperatures ranging from -32 to -34oC (-25 to 30oF), under a large heated tent to keep the concrete from freezing. Running five meters deep and measuring 6,500 cubic meters (230,000 cubic feet) and 6,000 cubic meters (212,000 cubic feet) for the Moscow and St. Petersburg Towers, respectively, the foundation utilized a relatively standard rebar cage and wooden formwork.

The foundation pile cap tops 215 piles beneath the Moscow Tower and 191 piles beneath the St. Petersburg Tower. An additional 76 piles for the combined-pile raft foundation support the podium building. Each pile measures 1.2 meters (47.25 inches) in diameter and 20 meters (65.5 feet) in length, and is drilled down through the site's thick layer of clay to the underlying limestone bedrock. The alternative - a shallow foundation at the bottom of the basement that would act as a big raft in the clay layer - would have required large stabilizing walls in the basement that would have significantly comprised circulation and the basement-level program. The six-level basement includes more than 2,200 parking spaces, electrical equipment and enlarged file compartments.

Curtain Wall
The basement also accommodates an unusual site runoff management facility that responds to the limited capacity of Moscow's sewer system to absorb large surges of water. Rainwater collection tanks located in the basement temporarily retain runoff water before it is slowly discharged into the municipal system at a manageable rate. While such measures are unusual for Moscow, this system protects Capital City and the immediate site from flooding. Additionally, a water retention pond for fire defense minimizes on-site water and energy consumption.

Typical cast-in-place concrete construction utilizing pumps to move the concrete to upper floors was utilized for the towers and podium building and towers.

Curtain Wall

The design team collaborated with German curtain wall specialists Schüco to create a dynamic façade for the towers and podium building. The towers are enclosed in a unitized panel system with four-sided structural-silicone glazing. The aluminum panels compose a shifting super grid that resonates with the tower's shifting blocks. The panels also shift in plan, some protruding outward while others are slightly inset to accommodate vertical LED lighting. Within this shifting grid, silver-reflected glass panels alternate between shadow box construction and ceramic frit coating to control solar heat gain. The curtain wall also integrates electronically operable windows in all apartments. These windows are designed for use in accordance with the mechanical systems, offering residents flexible control over their interior environment.

The podium building's façade establishes a more striking presence, utilizing two systems: a structural silicone stick system and a point-supported planar glass system. The main three walls to the south incline at a 10-degree slope and are constructed of a four-way glazing system with sunshades on the south side. The remaining vertical curtain walls are fabricated with flat and curved aluminum panels with vision glass that form a gently curving wall extending from south to north. The three retail and spa floors are denoted by a point-supported planar façade system with stainless steel spider supports and specially designed glass columns. Three automatic revolving doors with air curtains provide the primary means of entry.

One of the project's more complex curtain wall systems is the folded, angled curtain wall covering the retail atrium and spa pool and making the main entrance (see Figure 6). The curtain wall's geometry tapers in plan and angles in section, allowing for water drainage and ice collection and removal. The glass panels are heated to adapt to Moscow's winter climate. The skylight system - an undulating, folding clear and translucent glazing - also resonates with the interior pedestrian "fashion street" at the ground level by creating a fashion/fabric analogy.

The realization of the curtain wall was a global effort. Designed in Germany, fabricated in Turkey, tested in England at Taylor Woodrow Technology Centre, supervised by US consulting firm Israel Berger & Associates, and assembled in Moscow by Aygun aluminum; the curtain walls are one of Capital City's more complex elements and necessitated multiple iterations before finalizations. Wind tunnel tests and computer analyses were performed to determine areas of positive and negative pressure, after which on-site mock-ups provided critical feedback dictating the use of thicker glass in certain locations. After several tests, the necessary thickness for the exterior glass on the upper floors of the St. Petersburg and Moscow Towers was deemed to be 8 millimeters (0.25 inches) and 10 millimeters (0.375 inches), respectively.


As a pioneering project in Moscow, Capital City has forged many new pathways for the city's real estate and construction industries. Through integrated design and engineering, the project provides a model for mixed-use development, which remains rare in the city, and further establishes a new identity for Moscow.

As much as the project demanded innovative solutions and processes, an equally important legacy of Capital City's development is the design, construction and procedural precedents it helped to establish in Moscow. The collaboration throughout the project - between the client, design team, and local engineering, construction agencies - represents a foundation of exchange between the global and local tall building industries that paves the way for future advances.
