Tutor Perini Corp. of Sylmar has won new projects in the U.S. territory of Guam totaling $77 million, the company announced Monday.

The three contracts were awarded to Tutor Perini’s Guam subsidiary Black Construction Corp. for engineering and construction work.

Black Construction Corp.’s bid of nearly $41 million was the lowest bid for the Ordot Dump Closure Construction and Dero Road Sewer Improvements project. Construction will begin in early 2014 and be completed in the summer of 2015.

A contract of $23.8 million to upgrade the living areas of the Lockwood Terrace on Naval Base Guam will start in spring 2014 and be completed fall 2015.

The third project was awarded by Lotte Duty Free Retail in the amount of $12.7 million. The Seoul, South Korea company hired Tutor Perini to complete architectural work and construction finishes on retail spaces within Guam International Airport. Work is set to begin later this month and is expected to be completed within six months.

The announcements follow last week’s news that Tutor Perini’s subsidiary Tutor Saliba Corp. is being sued by the city of Los Angeles for work completed as part of a joint venture on a Los Angeles International Airport runway. City officials claim the $250 million runway was rebuilt incorrectly and is falling apart. Tutor Perini has not commented on the lawsuit.

Shares closed up 7 cents, or a fraction of a percent, to $23.75 on the New York Stock Exchange.
