PAUL LUKES: Building Envelope Consulting Services LLC consults in the protection of the building envelope against moisture penetration, weathering damage, movement stresses, and related problems. The firm consists primarily of Paul Lukes, a registered architect with over 46 years of experience in construction and architecture, whose focus has centered on exterior envelope issues and related technical concerns for over 36 years. To date, Paul has consulted on roughly 800 construction projects, ranging from wood-framed single-family residences to major brand new medical centers, creating an unrivaled concentration of construction expertise within a single mind. Projects span the full spectrum of building uses and construction technologies, including institutional, commercial, and residential buildings, ranging from wood-framed single-family homes to major institutions with post-tensioned concrete structures. Institutional projects include libraries, public and private schools, university buildings, museums, research facilities, hospitals, religious facilities, courthouses, visitor centers, fire stations and similar municipal facilities, as well as others. Commercial projects have included office buildings, hotels, resorts, retail buildings, production facilities, storage buildings, hangars, pools, corporate structures, and similar buildings. In the residential category, projects include condominium and apartment structures as well as single-family residences. However, within the single-family residential sector, PL:BECS primarily becomes involved with extremely high-end projects, whose typically greater complexity of systems warrants highly technical input. A very large majority of single-family projects fall in the multi-million dollar range.
