The amendment corresponds to the additional survey and engineering services that Lockwood, Andrews & Newriam, Inc. (LAN) has performed in order to adjust the project to meet new requirements and field conditions that were not apparent at the time the initial project scope was developed. The original contract for this project was executed on May 13, 2003 and formal notice to proceed was issued on July 7, 2003. At the time of contract authorization, the project entailed two separate phases described as follows: Phase I - Design of a 12-inch sewer main from a connection point on the existing M-272B trunk 7-7— main in Trinity Park, to the northwest to serve the redevelopment of the Montgomery Ward property and the proposed South of 7'h residential development. Smaller lines were to be extended across West 7th Street to the north of Trinity Park terminating at the intersection of 5'h and Greenleaf Streets. Phase 2 — Design of a 24-inch sewer main from a connection point on the existing M-545 trunk main in the proximity of the White Settlement Road / Jacksboro Highway intersection, to the west on White Settlement Road and South on Wimberley Street to a termination point at the Wingate Street intersection. Smaller lines were to be extended south on Adolph Street to serve the north portion of the Montgomery Ward property, and west on White Settlement Road to University Drive. The alignment south on Wimberley Street was initially selected by the City in order to replace the section of sewer main M-1312 in this area that had experienced chronic maintenance requirements. Downstream portions of the existing M-132 main in White Settlement Road were also to be replaced with service transfer to the new parallel sewer main. Other portions of the existing M-132 main not located in White Settlement Road were to remain in sen7ice. Following notice to proceed, LAN prepared a Conceptual Design Summary Report based upon the original scope. The report was submitted on September 4, 2003 and delip'-e-qti�d--the-same 307 West 7th Street,Suite 5250 Fort Worth,Texas 76102 817M0,0420 Pax:5'€7.620.01414.) www,lan-ina,com Mr. Liam Conlon June 15, 2004 Page 2 of 3 alignments as proposed in the original scope. These alignments were considered to be practical and were subsequently approved by the City (specifically Mr. Peter Fu, P.E. and Mr. Chris Harder, P.E.) at a meeting with LAN on September 12, 2003 (see conference memorandum 9116103). LAN then proceeded with topographic surveying and development of preliminary engineering plans. Since the initiation of the construction plan development, LAN has been directed to make several changes in the design scope associated with each phase. These are summarized as follows: Phase I Scope Changes: 1. Increase of sewer main size from 12-inches to 30-inches in order to accommodate future connection of re-routed M-134-R (M-1-C-C4-B) sewer main under design by Dunaway and Associates. Direction to increase the main size for this future connection was issued at the project meeting on September 12, 2003 (see conference memorandum 9116103). Associated flow rates from the M-134-R main to be accommodated by the future connection were provided by Mr. Chris Harder, P.E. of the City on October 7, 2003. However, LAN was required to perform an independent analysis of the additional flows generated from the Montgomery Ward re- development and adjacent service areas north of West 7`i' Street (see E-mail correspondence dated 1116103). LAN also performed additional coordination with Dunaway and assisted them with utility location work in support of the M-134-R re- route design program. Along with the line size increase, the revision required that LAN design a special junction box for connection with the existing M-272-B trunk main in Trinity Park. 2 Re-route of sewer main off of West 7"' and Carroll Streets and into the Montgomery Ward property following negotiation by LAN for easements from the developer. Provision of the easements eliminated approximately 1,300 linear feet of street repair and traffic control requirements from the project. The re-route was approved by Mr. Peter Fu, P.E. of the City(see conference memorandum 12129103) Phase 2 Scope Changes L Re-route of new sewer main from Wimberley Street to Currie Street due to grade conflicts with existing storm and raw water supply mains in Wimberley Street. The original alignment on Wimberley Street to Wingate Street (see Exhibit A) was considered to be unsuitable due to these conflicts. An alternative alignment on 'Currie Street (Yee Exhibit �) offered fewer conflicts with utilities and provided better flow line grades to serve upstrearn customers. Wimberley Street mains will still be replaced but with smaller lines and routings that will avoid the pnimary area of conflict at the intersection with Weisenberger Street, This revision was approved by Mr. Liam Conlon of the City following review of data obtained by LAN from their topographic survey and utility location work in support of the design program. The grade conflict was not apparent at the time of preparation of the Conceptual Design Report, The Curne Street afiDwhrnent eliminated the conflict and redo 1ped_--the General Project Correspondencei 1,2 Client"A m, nd I SuP1nwt06M4,do-_ Mr.Liam Cordon June 15,2004 Page 3 of 3 construction risk associated with the new sewer utility (see conference memorandum 11119103). 2. Provision of special siphon boxes to affect connection with new 2 1-inch sewer main in the south portion of Wimberlcy Street being designed by Graham and Associates and designated as DOE #2217. LAN worked directly with Graham to coordinate the two projects with corresponding meetings with the City Field Operations Division to verify existing conditions and improvement recommendations. Extension of the new M-132 main south on Currie Street offered the advantage of a direct connection with the Graham project and improved its associated depth and grades. The change offered an initial starting point from which to improve sewage collection flows throughout the Linwood Addition of Fort Worth. This advantage was initially recognized by Mr. Liam Conlon of the Water Department and subsequently by Mr. Fred Ehia, P.E. of the Engineering Department. Mr. Ehia is the City project manager for the DOE #2217 project being performed by Graham. He subsequently instructed Graham to revise their design to fit with the connection point to be provided by the LAN project (see conference memorandum 11119103). The activities and changes as outlined above have resulted in the need for additional meetings, surveying, and engineering design work in order to incorporate the additional project scope requirements. Hourly charges for personnel and lump sum costs associated with this work are summarized on Exhibit I attached. Based upon these scope changes, Amendment No. I has been developed in the amount of$22,350. This increase would adjust the engineering contract fee from $260,706 to $283,056. We hope the information as presented herein is adequate to your needs. Please do not hesitate to contact me should any additional information be required.
