LOS ANGELES-Jack Jibilian has been named president of Environmental Contracting Corp., succeeding founder Aram Arakelian, who will continue to manage the firm's preconstruction and budget services. Jibilian has been with Environmental Contracting Corp., a tenant improvement interiors and renovation contracting firm, for 15 years.

Jibilian, who most recently he was vice president and project manager at Environmental Contracting, joined the firm after graduating from the University Of Southern California School Of Architecture in 1997. During his tenure at ECC, he has managed more than two million square feet of interior and building renovation construction.

Arakelian will now serve as chairman of the board of Environmental Contracting, which he founded in 1984. ECC has grown into one of Southern California's leading interior construction firms.

Jibilian says that, as president, he will "focus on our core business and the day-to-day operations, freeing up Aram to concentrate to work with client's pre-construction budgeting process."

Environmental Contracting Corp. provides full general contracting services for interior and building renovation construction projects for a wide variety of commercial office space, entertainment, retail, and university users. The firm also has made numerous contributions to the construction industry, including helping to define the original Standard Work Letter and promoting the concept of partnering, and computing general conditions as a function of time rather than as a percentage of project cost, a practice that is now an industry standard.
