NEW YORK (TheStreet) -- Shares of Chicago Bridge & Iron (CBI) were falling 4.5% to $45.17 Friday after Scana (SCG) subsidiary South Carolina Electric & Gas filed a petition to push back the milestone schedule for the nuclear units the construction company is helping to build.

South Carolina Electric & Gas said that the completion of the Unit 2 will be pushed to 2019 from 2016. The company also said the cost to complete both units will likely increase to $11 billion from the project's initial cost of estimate of $9.8 billion.

The construction delays are due to design and fabrication issues related to the production of submodules used in the construction of the two nuclear units, according to Scana Chairman and CEO Kevin Marsh. The company is currently negotiating with Chicago Bridge & Iron and Westinghouse Electric, which is also involved in the construction of the units, over responsibility for the costs associated with the delays.

TheStreet Ratings team rates CHICAGO BRIDGE & IRON CO as a Hold with a ratings score of C. TheStreet Ratings Team has this to say about their recommendation:

"We rate CHICAGO BRIDGE & IRON CO (CBI) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, notable return on equity and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, generally higher debt management risk and a generally disappointing performance in the stock itself."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

• The revenue growth came in higher than the industry average of 3.8%. Since the same quarter one year prior, revenues rose by 12.4%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.
• The return on equity has improved slightly when compared to the same quarter one year prior. This can be construed as a modest strength in the organization. Compared to other companies in the Construction & Engineering industry and the overall market, CHICAGO BRIDGE & IRON CO's return on equity exceeds that of both the industry average and the S&P 500.
• CHICAGO BRIDGE & IRON CO's earnings per share declined by 23.9% in the most recent quarter compared to the same quarter a year ago. This company has reported somewhat volatile earnings recently. But, we feel it is poised for EPS growth in the coming year. During the past fiscal year, CHICAGO BRIDGE & IRON CO increased its bottom line by earning $4.98 versus $4.18 in the prior year. This year, the market expects an improvement in earnings ($5.68 versus $4.98).
• CBI's debt-to-equity ratio of 0.67 is somewhat low overall, but it is high when compared to the industry average, implying that the management of the debt levels should be evaluated further. Despite the fact that CBI's debt-to-equity ratio is mixed in its results, the company's quick ratio of 0.56 is low and demonstrates weak liquidity.
• The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed against the S&P 500 and did not exceed that of the Construction & Engineering industry. The net income has decreased by 23.6% when compared to the same quarter one year ago, dropping from $196.78 million to $150.41 million.
