The report expresses that problems were encountered that were not expected from the initial survey of the project. Excess work and cost was also due to unseasonal rainfall and Hurricane "Alicia". The original estimate of cost from Turner Collie & Braden on the emergency rehabilitation of the Catlett Sewer Main, was $125,000. At closing out of the project account the actual amount spent on the rehabilitation was $186,425.83. Engineering fees and on site inspection fees were $1+6,000 as originally proposed. If you should have any questions, please advise. JLH/me attachment • • CATLETT LANE SEWER - EMERGENCY REHABILITATION FOR THE CITY OF LA PORTE, TEXAS TURNER COLLIE & BRADEN JOB NOS. 26-00021-010 & 011' The Catlett Lane sewer consists of approximately 2,100 feet of 6-inch and 8-inch concrete sewer pipe. The sewer line is located in aback lot easement which is primarily 10 feet in width but necks down to 6 feet at several locations. The back lot easement is heavily congested with utilities, trees, bushes, fences, etc. It is also encroached upon by garages, fallout shelters, and yard buildings. The history of the line consisted of pluggage, failures, charging etc. almost as a daily occurrence. The project goal was to repair the line with minimal impact upon local residents. This was accomplished in a 72-working-day period which was plagued by unseasonable rain, a hurricane, and excessively wet ground for 19 of those days. On. seven more of those days it was also plagued by charging of the Catlett Lane Sewer caused by pluggage in the Farrington Main and problems with the subdivision lift station. The contractor also had to clean the Farrington Main on eight occasions to remove blockage which had caused charging of the Catlett Lane Sewer. The limited right-of-way, the congested easement, and wet ;round conditions all contributed to the necessity to u:~~ hand labor for excavation for entry pits, point repairs, and tap connections. The first step of the project was to clean the lines. Numerous blockages were encountered. These were later found to be caused primarily by dropped service connections. After cleaning, the lines were television inspected. Television inspection of the line from Valley Brook Drive to Piney Brook Drive revealed a deteriorated line with heavy root intrusion. Replacement of this approximately 1,100 foot section would have been very expensive because of the limited access and possible damage to private property. The decision to slip line this section with a 7-inch SDR 21 polyethylene liner pipe seemed to be the only viable alternative. This was accomplished and all the service connections reconnected. The sewer line section from Piney Brook to Farrington was found to be slip lined with 6-inch SDR polyethylene. Cleaning of this section incurred only normal problems; however, television inspection found an obstacle at every service connection. In addition, the television camera would catch at reverse slope (dip) locations. All service connections on this section -1- • • were excavated and reconnected to the liner. Many of these service connections had slipped because they were installed with homemade saddles. Two sections of sagged, bare polyethylene pipe were replaced. These were at apparent old entry pit locations. All excavation had to be performed by hand labor because of the wet soil conditions of the congested work areas. After completion of repairs to the sections described above, all repair locations were water tamped to speed consolidation of the backfill, fences damaged by construction were repairetii or replaced, construction damaged areas were sodded, and a general area clean-up was performed. Difficulties Encountered During Construction Which Affected The Cost of the Project 1. Rain delays and associated wet ground condition. 2. Congested narrow ROW. 3. Items 1 and 2 above necessitated the use of hand labor. 4. Charging problems associated with the Farrington Main and subdivision lift station. 5. Almost every service connection had slipped into the sewer line and required repair. 6. Dips in sewer line caught the television camera. Special Considerations 1. Manhole No. 4 will always have approximately 6 inches of standing water because of a bow in the sewer that exists downstream. The condition was improved by point repairs which removed part of the bowed section. 2. Manholes No. 5 and No. 6 will always have standing water because the flowlines of the outlet sewers of both manholes were originally constructed several inches higher than the inlets. Normal periodic maintenance will resolve the nuisance caused by these two items. Conclusion Basically the project has been very successful. Minimum resident complaints have been received about construction damage. Many residents have volunteered their opinion of being satisfied by the results. The contractor was responsive to the residents' requests and was considerate in his approach to minimize damage during construction. -2- . ~ • CATLETT LANE SEWER - EMERGENCY REHABILITATION FOR THE CITY OF LA PORTE, TEXAS TURNER COLLIE & BRADEN JOB NOS. 26-00021-010 & Oll The following is a brief list of work performed. The point repairs listed were required in order to clean and/or television inspect the sewer. Additional point repairs were required at all service c.:onnections to either reconnect failed taps to the existing polyethylene liner (between manholes No. 1 and No. 5) or to connect taps to the new polyethylene liner (between manholes No. 6 and the cleanout east of manhole No. 9). 1.

Spenwick MUD has been dissolved, and is presently receiving all city services. College View MUD will be dissolved on March 27, 1984. Spenwick MUD had no formal garbage collection contract before annexation. However, College View MUD has a three (3) year contract with Bay Area Disposal Service, cancelable only for failure to perform. The contract period is from July 1, ]983 through June 30,.7986. The Public Works. Department collected data in June 1983 and determined that the annexation 'of these two (2) areas would .stretch the ability of the Solid Waste Division to provide service to these areas. Rapid growth in the western portion of the city and the ~ixtt!~endina closing of the Harris County Landfil'7 will require an additional collection crew. In order to a17ow time to budget for the additional crew and equipment, and to shorten the contract period with Bay Area Disposal Service,~the Public Works Department has negotiated a contract with Bay Area Disposal Service fora one (1) year period beginning April 1;•1984 through March 31, 1985. The orginal contract price per month per residence was EIGHT Dollars ($8.00) per months The negotiated price is EIGHT DOLLARS AND FIFTY CENTS ($8.50) pe.r month per residence. The increase is due to the shortening of the contract and the increased service the contractor will have to provide to equal city service. The contractor will carry the required liablity insurance and obtain a ONE HUNDRED THOUSAND DOLLAR ($100,000) performance bond or post a FIFTEEN THOUSAND DOLLAR ($15,000) cash bond. The city will provide plastic bags to residents,~~and the contractor will be responsible for all other costs, including 7andfi~ll fees. This contract will be for College View and Spenwick. Although the city began collection in Spenwick on January 31, 1984, the development occurring in new subdivisions is rapidly expanding present routes to the limit. The contracting of these two (2) areas for one (1) year will a71ow the Solid Waste Division time to budget funds in October, purchase equipment;~~and reroute the entire city from four routes to six routes. • Page 2 Solid Waste Contract I recommend that the City Council authorize the City~Manger:'to~~sign a one (1) year contract with Bay Area DIsposa7 .Service for $8.50 per month per residence to provide solid waste collection,~equal to the city's service, for Spenwick and College View, beginning Apri~1 1, 'i984 through March 31, 1985.

The sewer line is located in aback lot easement which is primarily 10 feet in width but necks down to 6 feet at several locations. The back lot easement is heavily congested with ur.ilities, trees, bushes, fences, etc. It is also encroached upon by garages, fallout shelters, and yard buildings. The history of the line consisted of pluggage, failures, charging etc. almost as a daily occurrence. The project goal was to repair the line with minimal impact upon local residents. This was accomplished in a 72-working-day period which was plagued by unseasonable rain, a hurricane, and excessively wet ground for 19 of those days. On seven more of those days it was also plagued by charging of the Catlett Lane Sewer caused by pluggage in the Farrington Main and problems with the subdivision lift station. The contractor also had to •c lean the Farrington Main on eight occasions to remove blockage which had caused charging of the Catlett Lane Sewer. The limited right-of-way, the congested easement, and wet •~cround conditions all contributed to the necessity to use hand labor for excavation for entry pits, point repairs, and tap connections. The first step of the project was to clean the lines. Numerous blockages were encountered. These were later found to be caused primarily by dropped service connections. After cleaning, the lines were television inspected. Television inspection of the line from Valley Brook Drive to Piney Brook Drive revealed a deteriorated line with heavy root intrusion. Replacement of this approximatelyy 1,100 foot section would have been very expensive because of the limited access and possible damage to private property. The decision to slip line this section with a 7-inch SDR 21 polyethylene liner pipe seemed to be the only viable alternative. This was accomplished and all the service connections reconnected. The sewer line section from Piney Brook to Farrington was found to be slip lined with 6-inch SDR polyethylene. Cleaning of this section incurred only normal problems; however, television inspection found an obstacle at every service connection. In addition, the television camera would catch at reverse slope (dip) locations. All service connections on this section -1- • • were excavated and reconnected to the liner. Many of these service connections had slipped because they were installed with homemade saddles. Two sections of sagged, bare polyethylene pipe were replaced. These were at apparent old entry pit locations. All excavation had to be performed by hand labor because of the wet soil conditions of the congested work areas. After completion of repairs to the sections described above, all repair locations were water tamped to speed consolidation of the backfill, fences damaged by construction were repaire~.l or replaced, construction damaged areas were sodded, and a general area clean-up was performed. Difficulties Encountered During Construction Which Affected The Cost of the Project 1. Rain delays and associated wet ground condition. 2. Congested narrow ROW. 3. Items 1 and 2 above necessitated the use of hand labor. 4. Charging problems associated with the Farrington Main and subdivision lift station. 5. Almost every service connection had slipped into the sewer line and required repair. 6. Dips in sewer line caught the television camera. Special Considerations 1. Manhole No. 4 will always have approximately 6 inches of standing water because of a bow in the sewer that exists downstream. The condition was improved by point repairs which removed part of the bowed section. 2. Manholes No. 5 and No. 6 will always have standing water because the flowlines of the outlet sewers of both manholes were originally constructed several inches higher than the inlets. Normal periodic maintenance will resolve the nuisance caused by these two items. Conclusion Basically the project has been very successful. Minimum resident complaints have been received about construction damage. Many residents have volunteered their opinion of being satisfied by the results. The contractor was responsive to the residents' requests and was considerate in his approach to minimize damage during construction. -2- • CATLETT LANE SEWER - EMERGENCY REHABILITATION FOR THE CITY OF LA PORTE, TEXAS TURNER COLLIE & BRADEN JOB NOS. 26-00021-010 & O11 The following is a brief list of work performed.

The sewer line is located in aback lot easement which is primarily 10 feet in width but necks down to 6 feet at several locations. The back lot easement is heavily congested with u~ilities, trees, bushes, fences, etc. It is als:~ encroached upon by garages, fallout shelters, and yard buildings. The history of the line consisted of. pluggage, failures, charging etc. almost as a daily occurrence. The project goal was to repair the line with minimal impact upon local residents. This was accomplished in a 72-working-day period which was plagued by unseasonable rain, a hurricane, and excessively wet ground for 19 of those days. On seven more of those days it was also plagued by charging of the Catlett Lane Sewer caused by pluggage in the Farrington Main and problems with the subdivision lift station. The contractor also had to clean the Farrington Main on eight occasions to remove blockage which had caused charging of the Catlett Lane Sewer. The limited right-of-way, the congested easement, and wet -round conditions all contributed to the necessity to use hand labor for excavation for entry pits, point repairs, and tap connections. The first step of the project was to clean the lines. Numerous blockages were encountered. These were later found to be caused primarily by dropped service connections. After cleaning, the lines were television inspected. Television inspection of the line from Valley Brook Drive to Piney Brook Drive revealed a deteriorated line with heavy root intrusion. Replacement of this approximately 1,100 foot section would have been very expensive because of the limited access and possible damage to private property. The decision to slip line this section with a 7-inch SDR 21 polyethylene liner pipe seemed to be the only viable alternative. This was accomplished and all the service connections reconnected. The sewer line section from Piney Brook to Farrington was found to be slip lined with 6-inch SDR polyethylene. Cleaning of this section incurred only normal problems; however, television inspection found an obstacle at every service connection. In addition, the television camera would catch at reverse slope (dip) locations. All service connections on this section -1- • were excavated and reconnected to the liner. Many of these service connections had slipped because they were installed with homemade saddles. Two sections of sagged, bare polyethylene pipe were replaced. These were at apparent old entry pit locations. All excavation had to be performed by hand labor because of the wet soil conditions of the congested work areas. After completion of repairs to the sections described above, all repair locations were water tamped to speed consolidation of the backfill, fences damaged by construction were repaired or replaced, construction damaged areas were sodded, and a general area clean-up was performed. Difficulties Encountered During Construction Which Affected The Cost of the Project 1. Rain delays and associated wet ground condition. 2. Congested narrow ROW. 3. Items 1 and 2 above necessitated the use of hand labor. 4. Charging problems associated with the Farrington Main and subdivision lift station. 5. Almost every service connection had slipped into the sewer line and required repair. 6. Dips in sewer line caught the television camera. Special Considerations 1. Manhole No. 4 will always have approximately 6 inches of standing water because of a bow in the sewer that exists downstream. The condition was improved by point repairs which removed part of the bowed section. 2.

The sewer line section from Piney Brook to Farrington was found to be slip lined with 6-inch SDR polyethylene. Cleaning of this section incurred only normal problems; however, television inspection found an obstacle at every service connection. In addition, the television camera would catch at reverse slope (dip) locations. All service connections on this section -1- • were excavated and reconnected to the liner. Many of these service connections had slipped because they were installed with homemade saddles. Two sections of sagged, bare polyethylene pipe were replaced. These were at apparent old entry pit locations. All excavation had to be performed by hand labor because of the wet soil conditions of the congested work areas. After completion of repairs to the sections described above, all repair locations were water tamped to speed consolidation of the backfill, fences damaged by construction were repaired or replaced, construction damaged areas were sodded, and a general area clean-up was performed. Difficulties Encountered During Construction Which Affected The Cost of the Project 1. Rain delays and associated wet ground condition. 2. Congested narrow ROW. 3. Items 1 and 2 above necessitated the use of hand labor. 4. Charging problems associated with the Farrington Main and subdivision lift station. 5• Almost every service connection had slipped into the sewer line and required repair. 6. Dips in sewer line caught the television camera. Special Considerations 1. Manhole No. 4 will always have approximately 6 inches of standing water because of a bow in the sewer that exists downstream. The condition was improved by point repairs which removed part of the bowed section. 2. Manholes No. 5 and No. 6 will always have standing water because the flowlines of the outlet sewers of both manholes were originally constructed several inches higher than the inlets. Normal periodic maintenance will resolve the nuisance caused by these two items. Conclusion Basically the project has been very successful. Minimum resident complaints have been received about, construction damage. Many residents have volunteered their opinion of being satisfied by the results. The contractor was responsive to the residents' requests and was considerate in his approach to minimize damage during construction. -2- ~ ~ CATLETT LANE SEWER - EMERGENCY REHABILITATION FOR THE CITY OF LA PORTE, TEXAS TURNER COLLIE & BRADEN JOB NOS. 26-00021-010 & Oll The following is a brief list of work performed.

The sewer line is located in aback lot easement which is primarily 10 feet in width but necks down to 6 feet at several locations. The back lot easement is heavily congested with utilities, trees, bushes, fences, etc. It is also encroached upon by garages, fallout shelters, and yard buildings. The history of the line consisted of pluggage, failures, charging etc. almost as a daily occurrence. The project goal was to repair the line with minimal impact upon local residents. This was accomplished in a 72-working-day period which was plagued by unseasonable rain, a hurricane, and excessively wet ground for 19 of those days. On seven more of those days it was also plagued by charging of the Catlett Lane Sewer caused by pluggage in the Farrington Main and problems with the subdivision lift station. The contractor also had to clean the Farrington Main on eight occasions to remove blockage which had caused charging of the Catlett Lane Sewer. The limited right-of-way, the congested easement, and wet •.*,round conditions all contributed to the necessity to use hand labor for excavation for entry pits, point repairs, and tap connections. The first step of the project was to clean the lines. Numerous blockages were encountered. These were later found to be caused primarily by dropped service connections. After cleaning, the lines were television inspected. Television inspection of the line from Valley Brook Drive to Piney Brook Drive revealed a deteriorated line with heavy root intrusion.

In addition, two (2) paving projects were contracted to private companies for road construction on unimproved streets. From August 1980 to February 1984, approximately 35,600 linear feet, or 6.74 miles of street were reconstructed by City crews. This represents 102 city blocks, using 350 linear feet per block. Estimated total material cost for this program is $616,130, or $6.49 per square yard. In the same period, approximately 21,000 linear feet, or 3.98 miles of new street was constructed by City crews. This represents 60 city blocks. Estimated total material cost for this program is $363,446, or $6.49 per square yard. Paving projects for unimproved streets were performed by contract during this period. Approximately 45,900 linear feet, or 8.69 miles, representing 131 city blocks were constructed at a total cost of $1,980,688, or $16.18 per square yard. This cost includes engineering fees. Thirty five (35) streets remain on the unpaved street list assigned priorities by City Council. Using contract and force account labor, ten to fifteen of these streets should be paved this budget year.
