General Contractors • Lit l .., ., t A) `-,:,;.:)/ February 3, 2016 Jamie Brierton, PE City of Coppell- Public Works City of Coppell, TX PO Box 9478 Coppell, Texas 75019 Project: Edgewood Drive and Highland Meadow Circle Item: Request for time extension Mrs. Jamie Brierton: We hereby request a partial extension of contract time on the above contract for a total of Eighty One(81)consecutive calendar days. This request for an extension of time is based on the following delays created by the followings situations: 1. Densities using wrong proctor • September 29,2015 - Densities were taken along the subgrade and the underground utilities by HVJ Associates. The lab told us that the densities complied with the specification requirements. Based on that information we started to work on the subgrade preparation and all activities related to the concrete pavement, rebars and forms installation. Also, we scheduled concrete to be poured on Friday October 2nd. • October 1,2015 -The laboratory reports for the densities taken on September 29th were submitted, and, as the technician told us, the densities on Edgewood passed and complied with the project specification requirements. • October 2, 2015 — Ready to pour the concrete pavement, we received an email from the City inspector indicating that he was having a concern regarding the densities results, based on that he believed that the densities were taken using a proctor not representing the existing material on site. He gave us instructions to cancel the concrete pour and requested the lab to perform a new proctor test on the existing soil. • October 5,2015—New densities were taken using the new proctor and the results showed that the densities were out of specification edbuilders&ive.coni*Ptd Box 1002,Hurst,T.X.76053 1 Tel.

The inspector requested to remove the rebar and forms in order to rework the subgrade along as the trench until the densities reached specification requirements. • October 19, 2015 - After performing all necessary work on the subgrade, densities were taken and complied with specification requirements. We scheduled concrete and pour the concrete pavement that same day. For this situation,we respectfully request Twenty(20)calendar days. 2. In addition, and concurrently the project was affected by adverse weather conditions, which included record rain and thunderstorms in the Dallas — Fort Worth area during the year 2015. As you can see from the documents attached, from May 2015 through December 2015 there were 61 days with rain and/or thunderstorm having an average of 0.5" — 3" rainfall. These adverse weather conditions affected the soils conditions and made it almost impossible to perform work during the rainy days and sometimes the day after, depending on the rainfall. 3. For this situation, we respectfully request Sixty One(61)calendar days Also,we must comply with applicable Federal, state and local codes and standards, including compliance with: I.
