Building Alloy with Doka’s Full Package Solution

Nestled on the western edge of the 4th Street Bridge, Alloy stands as a pioneering skyscraper within Los Angeles' enchanting Historic Arts District. This towering edifice boldly ascends at a striking 45-degree angle from its foundation, crafting an exceptional architectural masterpiece that contributes a layer of intricacy to this remarkable endeavor.

The development unfolds as a harmonious blend of a five-story commercial edifice seamlessly intertwined with a soaring 36-story residential tower. Elevating itself above a multi-level parking complex, the tower dramatically rests upon six tiers, three of which are below-grade. A large parking expanse offers a generous capacity of 748 parking spaces, each meticulously planned around 103 distinct columns, with 72 columns boasting unique dimensions. These parking facilities are designated to serve the needs of both the expansive 105,000 square feet of office space and the 475 residential units.

In crafting Alloy, the designers drew inspiration from the robust grids characteristic of the district's historic warehouses and factories. The structure boasts distinctive concrete elements, showcasing board-formed walls, columns, beams, and soffits that grace the lobby at street level. Notably, an ornate ribbed architectural wall adorns the northern façade, which gazes out upon the majestic 4th Street Bridge. In total, the ambitious project commands the placement of over 70,000 cubic yards of concrete, a testament to its grandeur and architectural ambition.


The Challenges
This project involved multiple structures and project organization while on a tight schedule. Both the material procurement and design had tight deadlines and coordination was necessary with both local companies and support groups, such as engineering. Another challenge was managing multiple contracts for many contractors and suppliers on this large project.

Building Alloy called for the use of a hydraulic unit for automatic climbing core formwork and a specialized shoring to meet all unique shapes of the project’s plan. Continuous team coordination was vital for multiple structures needing formwork / shoring solutions, including:

• Columns
• Foundation walls
• Office core (Area 1 & 2)
• Office shoring
• Podium slab shoring (Area 1 & 2) with high decks, Level 2
• Podium level shear walls
• Shoring for parking garage P3 through L3
• Protection screens
• Residential tower shoring
• Tower core

The Solution
The solution for Alloy involved using a hydraulic unit for Super Climber SCP automatic climbing core formwork and a specialized Superdek shoring to efficiently meet all the unique shapes of the project’s complex plan. Doka’s Top50 core and shear wall formwork provided fast formwork setting in multiple uses and locations. By using Doka, Alloy had a full package solution from one vendor, which saved time on contractual and administrative tasks and ensured smooth job progression. Doka was chosen because they provided a fair price and competitive solution for all formwork needs for Alloy. It was an additional advantage that Doka’s pre-assembling services were complemented by the provided field service assistance.
In the end, the result is a striking development that’s considered “destination retail” with inspired design and creative offices.
