Terra-Petra is Proudly Recognized as an SBE – Small Business Enterprise

The SBE is a company-level diversity certification. Non-industry specific it is issued by a local or state government. Terra-Petra’s SBE certification is issued by the State of California.

Eligibility for certification as a Small Business Enterprise varies depending on the issuer. Requirements include the number of employees, the length of time the company has been in business and the net worth of the company’s owner.

In order for a small business to be eligible for certification, the small business must meet the following requirements in California:

  • Be independently owned and operated
  • Not dominant in the field of operation
  • The principal office must be located in California
  • Owners (officers, if a corporation) domiciled in California
  • A business with 100 or fewer employees; an average annual gross receipt of $15 million or less, over the last three tax years.
    • A small business will automatically be designated as a microbusiness, if gross annual receipts are less than $3,500,000; or the small business is a manufacturer with 25 or fewer employees.

Upon meeting the Small Business Certification eligibility requirements, certified small business (SBs) and microbusinesses (MBs) are entitled to the following benefits:

  • A five percent (5%) bid preference on applicable State solicitations.
  • Certified small business/microbusinesses are eligible for the State’s Small Business Participation Program. This program sets a goal for the use of small businesses in at least 25% of the State’s overall annual contract dollars.
  • Under the Prompt Payment Act, the State must pay a certified SB / MB higher interest penalty for late payment of an undisputed invoice. Prompt payment penalties for construction firms are addressed separately under Public Contract Code, Section 10261.5.

The Britely, a New Member’s Club in Los Angeles, Is Feather-Filled and Fabulous

There’s this famous Oscar Wilde quote: “Everything in moderation, including moderation.” That very well could be plastered on the gilded door of The Britely, a new member’s only club in Los Angeles where maximalism is the modus operandi. There’s not one, but two Wolfgang Puck restaurants—one of which is painted a flamingo pink. Their rooftop bar, with sweeping views of L.A.’s urban sprawl, is adorned in jade palmeral-tiger print. Then there’s the hangout de resistance: an underground lounge with turquoise banquettes, gold lamé pillows, Hollywood Regency feather lamps, and a bowling alley. Simply put: it’s a place where you can have some serious fun. (Or as Estelle Lacroix, The Britely’s managing director puts it, “a little self-indulgence.”)

First Look Inside Wolfgang Puck’s Pair of New Restaurants at Pendry West Hollywood

Wolfgang Puck is making a pizza. The 71-year-old chef, who has become a household name from his airport eateries, grocery line, and upscale establishments, has been making pizza for a very long time. Best known for creating the smoked salmon pizza at Spago, which was one of the city’s first restaurants to have a wood-fired oven, Puck is contemplating the signature pizza at his new daytime hotel cafe Ospero.

He stretches the dough while posing for the camera, as if this was a shoot for a glossy fashion magazine. Puck is always posing, holding a dish out for maximum exposure. He, and the team at Ospero and the penthouse restaurant Merois, will likely need it as the ongoing pandemic continues to hamper an ideal opening scenario at the massive new Pendry West Hollywood.

Vapor Intrusion Mitigation System – Fontana, CA

Terra-Petra has been chosen to provide environmental engineering services for the design of the vapor intrusion mitigation system (VIMS) design for a new logistics center in Fontana, CA.

Over the last couple of years, we have seen an increased demand for vapor intrusion mitigation systems to be designed and installed at large commercial warehouse type buildings. The main driving force appears to be the environmental personality of the property in which the buildings are being constructed. The site history will vary, but a history of industrial or commercial use where the site was subject to a chemical release of some sorts is the commonality.

Whether it be a petroleum hydrocarbon (TPH) impact from a former oil field/oil well or a Volatile Organic Compound (VOC) release from a dry cleaner or manufacturing facility the potential impacts on the health and safety of the future occupants of the building is what needs to be addressed.

Terra-Petra is well equipped at designing these systems for the current conditions, as well as building in contingency design features for potential future changes. Essentially, we design passive venting systems that are easily upgradable to active subslab depressurization systems (with remote telemetry and remote system monitoring and maintenance built into it if such a conversion is warranted in the future).

The proposed development in Fontana will consist of the construction of a new warehouse building having an approximate 260,650 SF footprint. The vapor mitigation measures will specifically include a “passive” vapor barrier beneath the office areas of the planned warehouse building, and the installation of  a passive ventilation layer beneath the vapor barrier. Inclusion of a ventilation layer beneath the vapor barrier would enable it to be made “active” at a later date by adding in-line fans, such as those used for radon mitigation, to the vertical riser pipes inside the warehouse.
