Contingencies and Commitments [Abstract]
Contingencies and Commitments	(6) Contingencies and Commitments The Company and certain of its subsidiaries are involved in litigation and are contingently liable for commitments and performance guarantees arising in the ordinary course of business. The Company and certain of its customers have made claims arising from the performance under their contracts. The Company recognizes certain significant claims for recovery of incurred cost when it is probable that the claim will result in additional contract revenue and when the amount of the claim can be reliably estimated. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims. In addition, because most contingencies are resolved over long periods of time, assets and liabilities may change in the future due to various factors. Several matters are in the litigation and dispute resolution process. The following discussion provides a background and current status of the more significant matters. Long Island Expressway/Cross Island Parkway Matter The Company reconstructed the Long Island Expressway/Cross Island Parkway Interchange project for the New York State Department of Transportation (the “NYSDOT”). The $130 million project was substantially completed in January 2004 and was accepted by the NYSDOT as finally complete in February 2006. The Company incurred significant added costs in completing its work and suffered extended schedule costs due to numerous design errors, undisclosed utility conflicts, lack of coordination with local agencies and other interferences for which the Company believes the NYSDOT is responsible. In March 2011, the Company filed its claim and complaint with the New York State Court of Claims and served to the New York State Attorney General’s Office, seeking damages in the amount of $53.8 million. In May 2011, the NYSDOT filed a motion to dismiss the Company’s claim on the grounds that the Company had not provided required documentation for project closeout and filing of a claim. In September 2011, the Company reached agreement on final payment with the Comptroller’s Office on behalf of the NYSDOT which resulted in an amount of $0.5 million payable to the Company and formally closed out the project allowing the Company to re-file its claim. The Company re-filed its claim in the amount of $53.8 million with the NYSDOT in February 2012 and with the Court of Claims in March 2012. In May 2012, the NYSDOT served its answer and counterclaims in the amount of $151 million alleging fraud in the inducement and punitive damages related to disadvantaged business enterprise (“DBE”) requirements for the project. The Court subsequently ruled that NYSDOT’s counterclaims may only be asserted as a defense and offset to the Company’s claims and not as affirmative claims. In November 2014, the Appellate Division First Department affirmed the dismissal of the City’s affirmative defenses and counterclaims based on DBE fraud. The Company does not expect the counterclaims to have any material effect on its consolidated financial statements. Management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time. Fontainebleau Matter Desert Mechanical Inc. (“DMI”) and Fisk Electric Company (“Fisk”), wholly owned subsidiaries of the Company, were subcontractors on the Fontainebleau Project in Las Vegas (“Fontainebleau”), a hotel/casino complex with approximately 3,800 rooms. In June 2009, Fontainebleau filed for bankruptcy protection, under Chapter 11 of the U.S. Bankruptcy Code, in the Southern District of Florida. Fontainebleau is headquartered in Miami, Florida. DMI and Fisk filed liens in Nevada for approximately $44 million, representing unreimbursed costs to date and lost profits, including anticipated profits. Other unaffiliated subcontractors have also filed liens. In June 2009, DMI filed suit against Turnberry West Construction, Inc., the general contractor, in the 8th Judicial District Court, Clark County, Nevada (the “District Court”), and in May 2010, the court entered an order in favor of DMI for approximately $45 million. In January 2010, the Bankruptcy Court approved the sale of the property to Icahn Nevada Gaming Acquisition, LLC, and this transaction closed in February 2010. As a result of a July 2010 ruling relating to certain priming liens, there was approximately $125 million set aside from this sale, which is available for distribution to satisfy the creditor claims based on seniority. At that time, the total estimated sustainable lien amount was approximately $350 million. The project lender filed suit against the mechanic’s lien claimants, including DMI and Fisk, alleging that certain mechanic’s liens are invalid and that all mechanic’s liens are subordinate to the lender’s claims against the property. The Nevada Supreme Court ruled in October 2012 in an advisory opinion at the request of the Bankruptcy Court that lien priorities would be determined in favor of the mechanic lien holders under Nevada law. In October 2013, a settlement was reached by and among the Statutory Lienholders and the other interested parties. The Bankruptcy Court appointed a mediator to facilitate the execution of that settlement agreement. Mediation is ongoing. Management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time. Honeywell Street/Queens Boulevard Bridges Matter In 1999, the Company was awarded a contract for reconstruction of the Honeywell Street/Queens Boulevard Bridges project for the City of New York (the “City”). In June 2003, after substantial completion of the project, the Company initiated an action to recover $8.8 million in claims against the City on behalf of itself and its subcontractors. In March 2010, the City filed counterclaims for $74.6 million and other relief, alleging fraud in connection with the DBE requirements for the project. In May 2010, the Company served the City with its response to the City’s counterclaims and affirmative defenses. In August 2013, the Court granted the Company’s motion to dismiss the City’s affirmative defenses and counterclaims relating to fraud. The Company does not expect ultimate resolution of this matter to have any material effect on its consolidated financial statements. Westgate Planet Hollywood Matter Tutor-Saliba Corporation (“TSC”), a wholly owned subsidiary of the Company, contracted to construct a timeshare development project in Las Vegas which was substantially completed in December 2009. The Company’s claims against the owner, Westgate Planet Hollywood Las Vegas, LLC (“WPH”), relate to unresolved owner change orders and other claims. The Company filed a lien on the project in the amount of $23.2 million, and filed its complaint with the District Court, Clark County, Nevada. Several subcontractors have also recorded liens, some of which have been released by bonds and some of which have been released as a result of subsequent payment. WPH has posted a mechanic’s lien release bond for $22.3 million. WPH filed a cross-complaint alleging non-conforming and defective work for approximately $51 million, primarily related to alleged defects, misallocated costs, and liquidated damages. WPH revised the amount of their counterclaims to approximately $45 million. Following multiple post-trial motions, final judgment was entered in this matter on March 20, 2014. TSC was awarded total judgment in the amount of $19.7 million on its breach of contract claim, which includes an award of interest up through the date of judgment, plus attorney’s fees and costs. WPH has paid $0.6 million of that judgment. WPH was awarded total judgment in the amount of $3.1 million on its construction defect claims, which includes interest up through the date of judgment. The awards are not offsetting. WPH and its Sureties have filed a notice of appeal. TSC has filed a notice of appeal on the defect award. In July 2014, the Court ordered WPH to post an additional supersedeas bond on appeal, in the amount of $1.7 million, in addition to the lien release bond of $22.3 million, which increases the security up to $24.0 million. The Nevada Supreme Court has not yet ruled on this matter. The Company does not expect ultimate resolution of this matter to have any material effect on its consolidated financial statements. Management has made an estimate of the total anticipated recovery on this project and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time. U.S. Department of Commerce, National Oceanic and Atmospheric Administration Matter Rudolph and Sletten, Inc. (“R&S”), a wholly owned subsidiary of the Company, entered into a contract with the United States Department of Commerce, National Oceanic and Atmospheric Administration (“NOAA”) for the construction of a 287,000 square-foot facility for NOAA’s Southwest Fisheries Science Center Replacement Headquarters and Laboratory in La Jolla, California. The contract work began on May 24, 2010, and was substantially completed in September 2012. R&S incurred significant additional costs as a result of a design that contained errors and omissions, NOAA’s unwillingness to correct design flaws in a timely fashion and a refusal to negotiate the time and pricing associated with change order work. R&S has filed three certified claims against NOAA for contract adjustments related to the unresolved Owner change orders, delays, design deficiencies and other claims. The First Certified Claim was submitted on August 20, 2013, in the amount of $26.8 million ("First Certified Claim") and the Second Certified Claim was submitted on October 30, 2013, in the amount of $2.6 million ("Second Certified Claim") and the Third Certified Claim was submitted on October 1, 2014 in the amount of $0.7 million (“Third Certified Claim”). NOAA requested an extension to issue a decision on the First Certified Claim and on the Third Certified Claim, but did not request an extension of time to review the Second Certified Claim. On January 6, 2014, R&S filed suit in the United States Federal Court of Claims on the Second Certified Claim plus interest and attorney's fees and costs. This was followed by a submission of a lawsuit on the First Certified Claim on July 31, 2014. In February 2015, the Court denied NOAA’s motion to dismiss the Second Certified Claim. In March 2015, the Contracting Officer issued decisions on all Claims accepting a total of approximately $1.0 million of claims and denying approximately $29.5 million of claims. On April 14, 2015, the Court consolidated the cases. No trial date has been set. Management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time. Five Star Electric Matter In the third quarter of 2015, Five Star Electric Corp. ("Five Star"), a subsidiary of the Company that was acquired in 2011, entered into a tolling agreement related to an ongoing investigation being conducted by the United States Attorney for the Eastern District of New York (“USAO EDNY”). The tolling agreement extended the statute of limitations to avoid the expiration of any unexpired statute of limitations while the investigation is pending. Five Star has been cooperating with the USAO EDNY since late June 2014, when it was first made aware of the investigation, and has been providing information related to its use of certain minority-owned, women-owned, small and disadvantaged business enterprises and, in addition, most recently, information regarding certain of Five Star’s employee compensation, benefit and tax practices. The investigation covers the period of 2005-2014. The Company cannot predict the ultimate outcome of the investigation and cannot accurately estimate any potential liability that Five Star or the Company may incur or the impact of the results of the investigation on Five Star or the Company. Alaskan Way Viaduct Matter In January 2011, Seattle Tunnel Partners (“STP”), a joint venture between Dragados USA, Inc. and the Company, entered into a design-build contract with the Washington State Department of Transportation ("WSDOT") for the construction of a large diameter bored tunnel in downtown Seattle, King County, Washington to replace the Alaskan Way Viaduct, also known as State Route 99. The construction of the large diameter bored tunnel requires the use of a tunnel boring machine (“TBM”). In December 2013, the TBM struck a steel pipe, installed by WSDOT as a well casing for an exploratory well. The TBM was damaged and was required to be shut down for repair. STP has asserted that the steel pipe casing was a differing site condition that WSDOT failed to properly disclose. The Disputes Review Board mandated by the contract to hear disputes issued a decision finding the steel casing was a Type I differing site condition. WSDOT has not accepted that finding. The TBM is insured under a Builder’s Risk Insurance Policy (“the Policy”) with Great Lakes Reinsurance (UK) PLC and a consortium of other insurers (the “Insurers”). STP submitted the claims to the insurer and requested interim payments under the Policy. The Insurers refused to pay and denied coverage. In June 2015, STP filed a lawsuit in the King County Superior Court, State of Washington (“Washington Superior Court”) seeking declaratory relief concerning contract interpretation as well as damages as a result of the Insurers’ breach of its obligations under the terms of the Policy. WSDOT is deemed a plaintiff since WSDOT is an insured under the Policy and had filed its own claim for damages. Trial is scheduled for June 2017. In April 2016, the Insurers filed a motion with the Court of Appeals seeking dismissal of STP’s claims. The commissioner’s ruling is pending before the Court of Appeals. In October 2015, WSDOT filed a complaint against STP in the Washington Superior Court for breach of contract and declaratory relief concerning contract interpretation. Said Complaint was dismissed. In March 2016, WSDOT refiled action against STP in Thurston County Superior Court. In July 2016, STP filed its answer to WSDOT’s complaint and filed a counterclaim against WSDOT and against the manufacturer of the TBM. As of June 2016, the Company has concluded that the potential for a material adverse financial impact due to the Insurer’s and WSDOT’s respective legal actions are neither probable nor remote. Management has made an estimate of the total anticipated recovery on this project and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

(6) Contingencies and Commitments

The Company and certain of its subsidiaries are involved in litigation and are contingently liable for commitments and performance guarantees arising in the ordinary course of business. The Company and certain of its customers have made claims arising from the performance under their contracts. The Company recognizes certain significant claims for recovery of incurred cost when it is probable that the claim will result in additional contract revenue and when the amount of the claim can be reliably estimated. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims. In addition, because most contingencies are resolved over long periods of time, assets and liabilities may change in the future due to various factors.

Several matters are in the litigation and dispute resolution process. The following discussion provides a background and current status of the more significant matters.

Long Island Expressway/Cross Island Parkway Matter

The Company reconstructed the Long Island Expressway/Cross Island Parkway Interchange project for the New York State Department of Transportation (the “NYSDOT”). The $130 million project was substantially completed in January 2004 and was accepted by the NYSDOT as finally complete in February 2006. The Company incurred significant added costs in completing its work and suffered extended schedule costs due to numerous design errors, undisclosed utility conflicts, lack of coordination with local agencies and other interferences for which the Company believes the NYSDOT is responsible.

In March 2011, the Company filed its claim and complaint with the New York State Court of Claims and served to the New York State Attorney General’s Office, seeking damages in the amount of $53.8 million. In May 2011, the NYSDOT filed a motion to dismiss the Company’s claim on the grounds that the Company had not provided required documentation for project closeout and filing of a claim. In September 2011, the Company reached agreement on final payment with the Comptroller’s Office on behalf of the NYSDOT which resulted in an amount of $0.5 million payable to the Company and formally closed out the project allowing the Company to re-file its claim. The Company re-filed its claim in the amount of $53.8 million with the NYSDOT in February 2012 and with the Court of Claims in March 2012. In May 2012, the NYSDOT served its answer and counterclaims in the amount of $151 million alleging fraud in the inducement and punitive damages related to disadvantaged business enterprise (“DBE”) requirements for the project. The Court subsequently ruled that NYSDOT’s counterclaims may only be asserted as a defense and offset to the Company’s claims and not as affirmative claims. In November 2014, the Appellate Division First Department affirmed the dismissal of the City’s affirmative defenses and counterclaims based on DBE fraud. The Company does not expect the counterclaims to have any material effect on its consolidated financial statements.

Management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time.

Fontainebleau Matter

Desert Mechanical Inc. (“DMI”) and Fisk Electric Company (“Fisk”), wholly owned subsidiaries of the Company, were subcontractors on the Fontainebleau Project in Las Vegas (“Fontainebleau”), a hotel/casino complex with approximately 3,800 rooms. In June 2009, Fontainebleau filed for bankruptcy protection, under Chapter 11 of the U.S. Bankruptcy Code, in the Southern District of Florida. Fontainebleau is headquartered in Miami, Florida.

DMI and Fisk filed liens in Nevada for approximately $44 million, representing unreimbursed costs to date and lost profits, including anticipated profits. Other unaffiliated subcontractors have also filed liens. In June 2009, DMI filed suit against Turnberry West Construction, Inc., the general contractor, in the 8th Judicial District Court, Clark County, Nevada (the “District Court”), and in May 2010, the court entered an order in favor of DMI for approximately $45 million.

In January 2010, the Bankruptcy Court approved the sale of the property to Icahn Nevada Gaming Acquisition, LLC, and this transaction closed in February 2010. As a result of a July 2010 ruling relating to certain priming liens, there was approximately $125 million set aside from this sale, which is available for distribution to satisfy the creditor claims based on seniority. At that time, the total estimated sustainable lien amount was approximately $350 million. The project lender filed suit against the mechanic’s lien claimants, including DMI and Fisk, alleging that certain mechanic’s liens are invalid and that all mechanic’s liens are subordinate to the lender’s claims against the property. The Nevada Supreme Court ruled in October 2012 in an advisory opinion at the request of the Bankruptcy Court that lien priorities would be determined in favor of the mechanic lien holders under Nevada law.

In October 2013, a settlement was reached by and among the Statutory Lienholders and the other interested parties. The Bankruptcy Court appointed a mediator to facilitate the execution of that settlement agreement. Mediation is ongoing.

In May 2010, the Company served the City with its response to the City’s counterclaims and affirmative defenses. In August 2013, the Court granted the Company’s motion to dismiss the City’s affirmative defenses and counterclaims relating to fraud.

The Company does not expect ultimate resolution of this matter to have any material effect on its consolidated financial statements.

Westgate Planet Hollywood Matter

Tutor-Saliba Corporation (“TSC”), a wholly owned subsidiary of the Company, contracted to construct a timeshare development project in Las Vegas which was substantially completed in December 2009. The Company’s claims against the owner, Westgate Planet Hollywood Las Vegas, LLC (“WPH”), relate to unresolved owner change orders and other claims. The Company filed a lien on the project in the amount of $23.2 million, and filed its complaint with the District Court, Clark County, Nevada. Several subcontractors have also recorded liens, some of which have been released by bonds and some of which have been released as a result of subsequent payment. WPH has posted a mechanic’s lien release bond for $22.3 million.

WPH filed a cross-complaint alleging non-conforming and defective work for approximately $51 million, primarily related to alleged defects, misallocated costs, and liquidated damages. WPH revised the amount of their counterclaims to approximately $45 million.

Following multiple post-trial motions, final judgment was entered in this matter on March 20, 2014. TSC was awarded total judgment in the amount of $19.7 million on its breach of contract claim, which includes an award of interest up through the date of judgment, plus attorney’s fees and costs. WPH has paid $0.6 million of that judgment. WPH was awarded total judgment in the amount of $3.1 million on its construction defect claims, which includes interest up through the date of judgment. The awards are not offsetting. WPH and its Sureties have filed a notice of appeal. TSC has filed a notice of appeal on the defect award. In July 2014, the Court ordered WPH to post an additional supersedeas bond on appeal, in the amount of $1.7 million, in addition to the lien release bond of $22.3 million, which increases the security up to $24.0 million. The Nevada Supreme Court has not yet ruled on this matter.

The Company does not expect ultimate resolution of this matter to have any material effect on its consolidated financial statements. Management has made an estimate of the total anticipated recovery on this project and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the consolidated financial statements at that time.

U.S. Department of Commerce, National Oceanic and Atmospheric Administration Matter

Rudolph and Sletten, Inc. (“R&S”), a wholly owned subsidiary of the Company, entered into a contract with the United States Department of Commerce, National Oceanic and Atmospheric Administration (“NOAA”) for the construction of a 287,000 square-foot facility for NOAA’s Southwest Fisheries Science Center Replacement Headquarters and Laboratory in La Jolla, California. The contract work began on May 24, 2010, and was substantially completed in September 2012. R&S incurred significant additional costs as a result of a design that contained errors and omissions, NOAA’s unwillingness to correct design flaws in a timely fashion and a refusal to negotiate the time and pricing associated with change order work.

R&S has filed three certified claims against NOAA for contract adjustments related to the unresolved Owner change orders, delays, design deficiencies and other claims. The First Certified Claim was submitted on August 20, 2013, in the amount of $26.8 million ("First Certified Claim") and the Second Certified Claim was submitted on October 30, 2013, in the amount of $2.6 million ("Second Certified Claim") and the Third Certified Claim was submitted on October 1, 2014 in the amount of $0.7 million (“Third Certified Claim”).

NOAA requested an extension to issue a decision on the First Certified Claim and on the Third Certified Claim, but did not request an extension of time to review the Second Certified Claim. On January 6, 2014, R&S filed suit in the United States Federal Court of Claims on the Second Certified Claim plus interest and attorney's fees and costs. This was followed by a submission of a lawsuit on the First Certified Claim on July 31, 2014. In February 2015, the Court denied NOAA’s motion to dismiss the Second Certified Claim. In March 2015, the Contracting Officer issued decisions on all Claims accepting a total of approximately $1.0 million of claims and denying approximately $29.5 million of claims. On April 14, 2015, the Court consolidated the cases. No trial date has been set.

Five Star Electric Matter

In the third quarter of 2015, Five Star Electric Corp. ("Five Star"), a subsidiary of the Company that was acquired in 2011, entered into a tolling agreement related to an ongoing investigation being conducted by the United States Attorney for the Eastern District of New York (“USAO EDNY”). The tolling agreement extended the statute of limitations to avoid the expiration of any unexpired statute of limitations while the investigation is pending. Five Star has been cooperating with the USAO EDNY since late June 2014, when it was first made aware of the investigation, and has been providing information related to its use of certain minority-owned, women-owned, small and disadvantaged business enterprises and, in addition, most recently, information regarding certain of Five Star’s employee compensation, benefit and tax practices. The investigation covers the period of 2005-2014.

The Company cannot predict the ultimate outcome of the investigation and cannot accurately estimate any potential liability that Five Star or the Company may incur or the impact of the results of the investigation on Five Star or the Company.

Alaskan Way Viaduct Matter

In January 2011, Seattle Tunnel Partners (“STP”), a joint venture between Dragados USA, Inc. and the Company, entered into a design-build contract with the Washington State Department of Transportation ("WSDOT") for the construction of a large diameter bored tunnel in downtown Seattle, King County, Washington to replace the Alaskan Way Viaduct, also known as State Route 99.

The construction of the large diameter bored tunnel requires the use of a tunnel boring machine (“TBM”). In December 2013, the TBM struck a steel pipe, installed by WSDOT as a well casing for an exploratory well. The TBM was damaged and was required to be shut down for repair. STP has asserted that the steel pipe casing was a differing site condition that WSDOT failed to properly disclose. The Disputes Review Board mandated by the contract to hear disputes issued a decision finding the steel casing was a Type I differing site condition. WSDOT has not accepted that finding.

The TBM is insured under a Builder’s Risk Insurance Policy (“the Policy”) with Great Lakes Reinsurance (UK) PLC and a consortium of other insurers (the “Insurers”). STP submitted the claims to the insurer and requested interim payments under the Policy. The Insurers refused to pay and denied coverage. In June 2015, STP filed a lawsuit in the King County Superior Court, State of Washington (“Washington Superior Court”) seeking declaratory relief concerning contract interpretation as well as damages as a result of the Insurers’ breach of its obligations under the terms of the Policy. WSDOT is deemed a plaintiff since WSDOT is an insured under the Policy and had filed its own claim for damages. Trial is scheduled for June 2017. In April 2016, the Insurers filed a motion with the Court of Appeals seeking dismissal of STP’s claims. The commissioner’s ruling is pending before the Court of Appeals.

In October 2015, WSDOT filed a complaint against STP in the Washington Superior Court for breach of contract and declaratory relief concerning contract interpretation. Said Complaint was dismissed. In March 2016, WSDOT refiled action against STP in Thurston County Superior Court. In July 2016, STP filed its answer to WSDOT’s complaint and filed a counterclaim against WSDOT and against the manufacturer of the TBM.

As of June 2016, the Company has concluded that the potential for a material adverse financial impact due to the Insurer’s and WSDOT’s respective legal actions are neither probable nor remote. Management has made an estimate of the total anticipated recovery on this project and such estimate is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.
