Thank you, Norma. Good morning, everyone and welcome to Orion Group Holdings' Second Quarter 2017 Earnings Conference Call and Webcast. Joining me today are Mark Stauffer orion Group Holdings' President and Chief Executive Officer; Dwayne Breaux, our Executive Vice President and Chief Operating Officer; and Chris DeAlmeida, our Executive Vice President and Chief Financial Officer. Regarding the format of the call, we have allocated about 15 minutes for prepared remarks, in which Mark and Chris will highlight our results and will update our market outlook. We will then open the call for sell-side analysts' questions for the remainder of the time. During the course of this conference call, we will make projections and other forward-looking statements regarding, among other things, our end markets, revenues, gross profits, gross margin, EBITDA, EBITDA margin, win rates, book to bill, backlog, projects in negotiation, administrative expenses, capital expenditures, pending awards as well as our estimates and assumptions regarding future growth. These statements are predictions that are subject to risks and uncertainties, including those described in our 10-K, that may cause actual results to differ materially from those statements. Moreover, past performance is not necessarily an indicator of future results. By providing this information, we undertake no obligation to update or revise any projections or forward-looking statements whether as a result of new development or otherwise. Also please note that EBITDA and EBITDA margin are non-GAAP financial measures under rules of the Securities and Exchange Commission, including Regulation G. Please refer to the reconciliations and definitions inclusive of the most comparable GAAP measures within the press release issued this morning, August 3, 2017. The release can be found on our website at www.oriongroupholdingsinc.com. This website is the principal platform for investor communications. Also, for additional discussion of risk factors that could cause actual results to differ materially from our current expectations, please refer to our quarterly filings with the SEC which are also available on the Investors section of the website. And with that, I'd like to turn the call over to Mark Stauffer, President and Chief Executive Officer. Mark?
