Page 3 of 3 EXHIBIT E CONSTRUCTION CONTRACT AND BID Enhanced Community Facilities Agreement(Sierra Vista)—Page 21 October 31,2005 City of Fort Worth, Texas Mayor and Council Communication COUNCIL ACTION: Approved on 11/8/2005 DATE: Tuesday, November 08, 2005 LOG NAME: 05SIERRAVISTA REFERENCE NO.: C-21137 SUBJECT: Authorize Execution of an Amendment to an Enhanced Community Facilities Agreement with Sierra Vista L.P. for Design Engineering and Construction of Community Facilities to Serve a 232 Lot Addition to the City of Fort Worth, Located off the Intersection of Riverside Drive and Berry Street and Surrounding Area RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute the attached Amended Enhanced Community Facilities Agreement in the amount not to exceed $3,129,491.00, with Sierra Vista L.P. for design engineering and the installation of community facilities in the Sierra Vista subdivision, and waive the requirements of Section II (7)(D)(5) of the Policy for the Installation of Community Facilities (Policy), as it applies to the City's participation. DISCUSSION: On December 14, 2004, (M&C G-14618) the City Council authorized the City Manager to execute an Enhanced Community Facilities Agreement (ECFA) in an amount not to exceed $2,778,950.00 with Sierra Vista, L.P. (the Developer) for the installation of infrastructure in the Sierra Vista subdivision and approved fee waivers under the Neighborhood Empowerment Zone (NEZ) Program. The ECFA has not been executed and if authorized, the amendment increasing City participation proposed herein will be incorporated into the original ECFA attached hereto. Increased costs necessitate the need to increase the City's financial participation and amend the ECFA. Some of the attachments to the ECFA are not included with this M&C, but will be available for review in the Department of Law. The proposed Sierra Vista project is the redevelopment of a 42.45 acre site in southeast Fort Worth in the Rolling Hills NEZ. The site is located at the intersection of Riverside Drive and Glen Gardens Drive, one block north of East Berry Street. The property currently contains 1,014 vacant deteriorated apartment units. The proposed project calls for the demolition of the apartment units and development of the site with 232 single-family units. The Developer will enter into a Security Agreement with the Fort Worth Housing Finance Corporation. The Security Agreement will require deed restrictions for all deeds conveying the Sierra Vista project property. Those deed restrictions will set forth building design standards. The City advertised the invitation to bid and the Developer will award one construction contract to the lowest responsible bidder. On December 14, 2004, (M&C G-14618) the City Council approved for total City participation in the amount of $2,778,950.00. After actual construction bids were received, street and storm drain construction costs increased by $783,057.00 and water and sewer construction costs decreased by $432,517.00 for a net increase of $350,540.00, therefore increasing the total City participation to a not to exceed amount of $3,129,391.00. Logname: 05SIERRAVISTA Page 1 of 2 Section II (7)(D)(5) of the Policy for the Installation of Community Facilities provides that if a developer awards one contract to construct all community facilities, City participation is limited to the amount the City would have paid if separate contracts were awarded to the lowest possible combination of bidders. If that Section is waived, the City's participation is increased by $82,684.45. Sierra Vista L.P. is in compliance with the City's M/WBE Ordinance by committing to a 20% M/WBE goal. The City's goal on this project is 20%. In addition to construction and engineering costs, $427,467.00 contingency is required for possible construction change orders. This project is located in COUNCIL DISTRICT 8.

This law provides that, in order to be awarded a contract as low bidder, nonresident bidders (out-of-State contractors whose corporate office or principal place of business are outside of the State of Texas) bid projects for construction, improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the same amount that a Texas resident bidder would be required too underbid a nonresident bidder in order to obtain a comparable contract in the State in which the nonresident's principal place of business is located. The appropriate blanks in Section A must be filled out by all out-of-State or nonresident bidders in order for your bid to meet specifications. The failure of out-of-State or nonresident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B. A.

(Attached) D-67 REMOVAL AND DISPOSAL OF'ASBESTOS.CEMENT PIPE A: It is the intent of the City of Fort Worth to comply with the requirements of the Asbestos National Emissions Standards for Hazardous Air Pollutants (NESHAP) found at 40 CFR Part 61, Subpart M. This specification will establish procedures to be used by all Excavators in the removal and disposal of asbestos cement pipe (ACP) in compliance 11/29/04 SC-49 i PART ® - SPECIAL CONDITIONS with NESHAP. Nothing in this specification shall be construed to void any.provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. ACP is defined under NESHAP as a Category II, non-friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61.150. A NESHAP notification must be filed with the Texas Department of Health. The notification must be filed.at least ten days prior to removal of the material. If it remains in its non - friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. The Environmental Protection Agency (EPA) defines friable as material, when dry, which may be crumbled, pulverized -or reduced to powder by hand pressures. C. The Generator of the hazardous.material is responsible for the identification and proper handling, transportation, and disposal of the material. Therefore, it is the policy of the City of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable. The Excavator is responsible to employ those means, methods, techniques and sequences to ensure this result. E. Compliance with all aspects of worker safety and health regulations including but not limited to the OSHA Asbestos Standard is the responsibility of the Excavator. The City of Fort Worth assumes no responsibility for compliance programs, which are the responsibility of the Excavator. (Copy of forms attached) F. The removal and disposal of ACP shall be subsidiary to the cost of installing the new pipe unless otherwise stated or indicated on the project plans or contract documents.

The cure period shall be of a duration recommended by the resin manufacturer, as modified for the inversion process, during which time the recirculation of the water and/or steam and cycling of the heat exchanger to maintain the temperature continues. 5. Cool-down: The Contractor shall cool the hardened cured-in-place pipe to a temperature below 100 F before relieving the static head in the inversion standpipe. Cool-down,may be accomplished by introducing cool water into the inversion. standpipe to replace water or steam being drained from a small hole made in the downstream end. Care shall be taken in the-release of the static head so that a vacuum will not be.developed that could-damage the newly installed cured-in-place pipe. F. SERVICE CONNECTIONS: After,the pipe has been installed, the Contractor shall reconnect the active service connections. This shall generally be done without excavation, and, in the case of non-man entry pipes, from the interior of the pipeline by means of a television camera and a cutting device that re-established them to not less than 90 percent capacity. Existing services shall be reinstated within 13 hours of installation.
