Allana Buick & Bers’ Work on Millennium Tower Featured in Business Insider


July 2017, Palo Alto, CA – Allana Buick & Bers’ (ABBAE) investigation work for Millennium Tower in San Francisco was featured in an article on Business Insider.

Millennium Tower, a $350 million skyscraper, is sinking 2 inches per year and has sunk 16 inches since 2008.

A tenant complained of “unexplained odors” in her unit and ABBAE was hired to perform an investigation on the building where gaps in the tenant’s walls were discovered. The gaps allowed smoke to permeate, meaning if a fire were to start, it could spread more quickly to her unit. These gaps are typically sealed with fire resistant caulking to prevent that situation from happening.

Bentonite HDPE Composite Waterproofing Systems



Sodium bentonite based waterproofing systems have steadily gained in popularity for below-grade application for both blindside and positive side construction. Although bentonite is in many household products, it has become one of the more versatile waterproofing materials available on the market today. Bentonite has many applications that include:

  • Under slab
  • Zero property line (blindside) construction
  • Back-filled walls
  • Earth-covered structures
  • Tunnels
  • Split-slab deck construction
  • Hydrostatic and non-hydrostatic site conditions

There are many manufacturers who offer a variety of bentonite waterproofing systems. Some of these product variations include standard bentonite sheet with a high-density polyethylene (HDPE) waterproofing membrane for repelling water or a multi-layer (bentonite, HDPE, and woven fabric) sheet membrane combination for repelling water and gas. The multi-layer sheet membrane is designed for use with shotcrete and cast-inplace concrete applications.

Fenestrations – Vinyl Windows



Windows are one of the most complex and expensive facets of the building envelope as they can account for approximately 10% of a building’s air inltration according to the U.S. Department of Energy, and can cost up to several thousand dollars per unit. The number, size, material choice and orientation of windows can make or break the energy efficiency of the entire building.

With so much on the line, it is important for windows to be weather and water tight. There are slightly less than 100 different American Society for Testing and Materials (ASTM) tests and 40 American Architectural Manufacturer’s Association (AAMA) standards, in addition to various other NFRC, ANSI, ASCE, CPSC, NFPA, UL and GANA Standards pertaining solely to windows. One of the most specified glazing products in multi and single family construction is the vinyl window.

Horizontal Above Grade Waterproofing




This paper is limited to protected type waterproofing membrane assemblies such as plaza decks, split slabs and concrete over wood decks assemblies. Traffic able waterproofing membrane systems like deck coatings and traditional protected roof assemblies such as inverted roof membrane assemblies are excluded from this discussion. Plaza decks are defined as exposed pedestrian surfaces constructed over parking or other occupied space, often built over structural concrete.

IBC defines garages as a type of occupancy, so technically plazas built over garages are over occupied space. Plaza decks can have many features such as driveways, pools, lawns, large mature trees, terrazzo and concrete toppings, glass screens, pavers over gravel or pedestals, planters, etc. Also discussed are protected waterproofing membranes over wood decks surfaced with many of the same types of permanent surfaces such as concrete topping slab, tile planters, etc. Typical Type V Podium assemblies are 4 to 5 stories of wood framed construction over a concrete podium, commonly used in California and other states for multi-family construction.

These elevated wood assemblies also have exposed, horizontal waterproofing with hard wearing surfaces like concrete which are integrated to the exterior wall claddings such as, masonry, stucco, siding, dimension stone, etc. Because these assemblies are surfaced with permanent landscape and hardscape features and integrated with doors, ramps and claddings elements, the wood framed waterproofed assemblies are also built with a life expectancy equivalent to the “life of the building”.
