2900 Weslayan Motor Bank Demolition

ONYX Constructors completed a transformative demolition project at 2900 Weslayan, Houston. This endeavor involved converting a motor bank into a surface parking lot while integrating updated storefront and curtain wall access into a formerly connected adjoining office building. Spanning 37,840 square feet, the project demanded intricate collaboration between ONYX Constructors, Griffin Partners, and AMB Architects, overcoming various complex challenges. The scope of this project entailed dismantling the integrated motor bank building, including the infrastructure, the main bank vault, canopies, drive-thru lanes, ATM areas, and the restoration of the building connection. A crucial aspect of the project was the safe and environmentally responsible removal of asbestos, showcasing ONYX's range of capabilities and their commitment to safety and sustainability.

Dealing with Limited Information on Utility Connections

Dealing with Limited Information on Utility Connections

The task of identifying utility connections like power, sewer, and water supply was complicated due to limited information from the building's original 1980's construction. This necessitated thorough due diligence and innovative strategies to disconnect these utilities without interrupting office building operations.

Temporary Barrier Installation

Temporary Barrier Installation

Installing a temporary barrier at the connection point to the attached building was a significant challenge, particularly given unpredictable weather conditions. The barrier, constructed using DensGlass and other weatherproof materials, was essential to maintain security and weather resistance until the new storefront and curtain wall system were established.

Addressing the Underground Teller Delivery System

Addressing the Underground Teller Delivery System

The presence of an underground teller delivery system necessitated strategic backfilling and the installation of structural barriers to prevent soil erosion and ensure the stability of the new asphalt paving.

Noise Restrictions and Working Hours

Noise Restrictions and Working Hours

Demolishing a building can be a disturbing process for those living or working in close proximity. Particularly as it pertains to noise. As a result, different areas of the city have specific parameters or working hours that regulate the timeframe each day in which excessive noise is allowed, or when a certain decibel level is permitted. These restrictions, which required a majority of the work to be conducted during business hours, combined with the disruption of tenants in the adjacent building required strategic planning not only as it relates to when to perform certain tasks, but how to execute those tasks in a more economical manner.

Removal of Existing Bank Vault

Removal of Existing Bank Vault

Removing a bank vault with 12” thick walls and roof is a relatively simple process when utilizing heavy equipment and a hydraulic hammer. However, it is a disruptive method. Due to noise sensitivity with occupants of the previously integrated building, paired with noise ordinance restrictions, a different approach was necessary. After careful planning and coordination, it was decided this task would be carried out the old-fashioned way with manpower and chipping hammers.
