Learning lessons from the much-delayed, 23-kilometer first phase of a Tel Aviv regional light-rail system, Israeli transportation officials have issued new engineering and project management tenders for the next two lines, with construction investment estimated at $8 million.

The fatal collapse of an underground parking lot in a Tel Aviv commercial district just weeks before construction was due to be completed has not only focused attention on the lack of safety and inspection in Israel’s construction industry but also raised question over potential engineering issues.

Shikun & Binui Group, Israel’s largest contractor, expects to take a loss of up to $30 million on debts owed since last year for infrastructure by its key overseas client, oil-sector-ravaged Nigeria.

The largest-ever infrastructure investment in Israel’s history—possibly $10 billion—has been halted and could face delay of at least a year following a March 27 domestic court ruling that rejected the framework for the U.S.- Israeli developers of the Leviathan offshore gas field.
