(WJE) is pleased to present this proposal to the City of Fort Worth to perform an engineering investigation of the failure of the recently conshucted Phase I of the Martha Lane Channel Improvement Project. SanFrancisco `I'he Martha Lane Channel Improvement project was designed to be consixucted in two phases. Phase I, seanre including Section A, B and B Alternate, extended from Station 201 + 56 to station 230 + 00, a distance of a Washington, Dc little over a half mile. Design Engineers for the project were Albert H. Halff Associates, Fort Worth; the Geotechnical Engineers were Terra-mar; and the Contractor far Phase I was Ramex Construction of EHA Division Houston. The Owner is the City of Fort Worth. The Phase I work was completed in February, 1999. The Phase II work, by another contractor, is currently nearing completion. Northbrook, /L Austin The open channel was constructed from downstream (East end) to upstream. The channel bottom (invert) C(wefand and sloped side walls were constructed of 3000 psi reinforced concrete, the invert being constructed first, followed in sequence by construction of the north slope wall and the south slope wall. The invert is shown to be 8 in. thick and 20 ft wide. The 2:1 slope walls are shown to be 6 in. thick and to extend laterally from 14.2 to 19 ft (typically 16 ft). During construction, random longitudinal cracks were noted to occur at about mid-height of the slope walls of the channel. During a heavy rainstorm in mid-March, 1999, approximately 3 in. of rainfall occurred in about one hour in the area which drains to the Martha Lane Channel. Shortly thereafter, it was discovered that extensive heaving and cracking of the channel invert and slope sides occurred near and at the downstream end. Also, a pipe connection broke on an 8 in. aerial sanitary sewer pipe which crosses the channel at about station 206 + 50. On July 7, 1999, the undersigned representative of WJE conducted a short site visit of the project with representatives of the City. We were then requested to prepare this proposal to perform an engineering investigation of the failure. The objective of the investigation is to assess the as-built condition of the structure and determining contributing causes for the failure. Based on our observations and our brief site visit, we anticipate performing the investigation with the assistance of sub-consultants. The initial phase of the investigation will include the following: Document review. We will review available and pertinent construction documents, including the contract for engineering design services, plans and specifications, construcrion records, and reports of testing perfornied after the failure. Site observations and documentation. A site visit will be conducted to document the nature and extent of the failure conditions. We will retain the services of a local surveying firm to perform a limited elevation survey of the channel bottom and slope walls at selected stations, the purpose being to provide a comparison with the design elevations and provide baseline elevations for comparison to future measurements, if needed, At this time, we do not anticipate taking additional soil borings, as we understand that the City had retained Rone Engineers to perform those tests shortly after the failure, and that the results of their tests will be provided for our use. �::��6�z� G��u�D r� 0� ��G�C�� (� 1�i� ��?��I �7 Wiss, Janney, Elstner Associates, Inc.
