Thank you, Valerie. Good morning everyone. And welcome to Orion Group Holdings' first quarter 2018 earnings conference call and webcast. Joining me today are Mark Stauffer, Orion Group Holdings' President and Chief Executive 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 update our market outlook. We will then open the call for questions. 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, backlog, projections and negotiation and pending awards, as well as our estimates and assumptions regarding our future growth, administrative expenses and capital expenditures. These statements are predictions that are subject to risks and uncertainty, 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 developments or otherwise. Also, please note that adjusted net income, adjusted earnings per share, 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 and reconciliation tables accompanying this earnings call, within the press release issued this morning. The press release can be found on our Web site at www.oriongroupholdingsinc.com. Also, for additional discussion of risk factors that could cause actual results to differ materially from our current expectations, please refer to our quarterly and annual filings with the SEC, which are also available on the Investors section of our Web site. And with that, I would like to turn the call over to Mark Stauffer, President and Chief Executive Officer. Mark?
