'I'Ty Ec"'TA"y 519 Flo INTEROFFICE MEMO DATE: AUGUST 17, 2018 TO: SUSAN ALANIS, ASSISTANT CITY MANAGER DOUGLAS W. BLACK, SR. ASSISTANT CITY ATTORNEY CYNTHIA GARCIA, PURCHASING MANAGER FROM: DOUGLAS W. WIERSIG, TPW DIRECTOR SUBJECT: EMERGENCY REPAIRS---EASTERN HILLS TUNNEL REPAIR This memo recommends an emergency procurement to mitigate ongoing underground soils settlement resulting in sinkholes on private property and around City infrastructure associated with a 54-inch diameter reinforced concrete pipe (RCP) that was tunneled under residential back yards as part of the Eastern Hills Drainage Improvements, Phase 2, in summer 2014. About 18 months after project completion, several small sinkholes were discovered in one of the residential back yards. Analysis revealed that a significant cause of that failure was due to a deficient City's specification for tunnel installation. In summer 2016, a repair was undertaken using an expansive grout of a type commonly used to fill voids outside of pipes and under pavements. Since that time, City staff have continued to observe the site, and sinkholes are continuing to develop, including a larger one in the same residential back yard that has experienced the Iion's share of the damage. An existing bagwall channel in the vicinity has also experienced structural failure and will be repaired under this contract. City staff and the project engineering consultant, Jacobs Engineering Group, have further investigated the causes of the tunnel installation failure and developed,additional remedial actions to provide a satisfactory permanent solution. Jacobs prepared a Best Value Request for Proposal, which was submitted to 3 contractors. Hayward Baker was the only contractor who submitted a proposal. Their original proposal was $387,000, which exceeded our estimate of $250,000. We intend to negotiate to reach a mutually agreeable scope and price. Due to the continuing and increased threat to public safety/private property caused by the growing number and size of the sinkholes,the threat to the integrity of the tunneled pipe and the bagwall channel, and the possibility of the acceleration of these hazards with each rain event, it is in the best interest of the City to immediately commence repairs under the emergency procurement exception to competitive bidding. Chapter 2, Article I, Section 2-9 of the City's Code of Ordinances and Section 252.022 of the Local Government Code exempts from normal bidding requirements expenditures that are necessary to preserve or protect public health or safety of the municipality's residents; and procurements necessary because of unforeseen damage to public machinery, equipment, or property. This memo is submitted to request authorization for emergency procurement of storm drain repair services.

Feel free to contact me at 972-294-5000 with any questions. HAYWARD BAKER,INC. Billy Fisher Division Manager Hayward Baker, Inc. 'THINK SAFE 661 Shahan Prairie Rd. Little Elm,Texas 75068 t: 972-294-5000 f: 972-294-2664 Equal Opportunity Employer Hayward Baker Inc. (HBI)is pleased to present this proposal for grout injection,excavation and backfill on the above referenced project. This quotation is based upon the following a. Site visits performed by Roy Doumet with HBI. b. Similar projects performed by HBI. C. Plans prepared by Jacobs dated May 2018. d. HBI is taking exception to the specification to the Probe Drilling and Contact Grouting specification. This letter and its attachments constitute Hayward Baker Inc.'s proposal and will be made a part of any contract between the CIient and HBI. The acceptance of the price of this proposal shall evidence the concurrent acceptance of all terms and conditions recited herein or incorporated by reference. INTRODUCTION It is understood by HBI that a hand-mined 54" RCP was installed to connect a storm drain to the existing pond. Following the completion of the original tunneling project,leaking joints within the tunnel are believed to be the cause of surface soil migration into the pipe, as a result several small sinkholes have propagated to the surface. HBI understands that probe and contact grouting has been specified to repair 327 linear feet of pipe. Deviation from the specification will be required for HBI to develop a grouting program. CONTACT GROUTING PROGRAM The purpose of the contact grouting is to fill void spaces between the RCP and the surrounding soil. HBI will drill grout hole/port utilizing an electric hammer drill.The holes will be in a 180-degree radial pattern in the top half of the existing RCP pipe.A cement bentonite grout will be pumped in the grout holes/ports,at a pre-determined pressure or volume cut off criteria. POLYURETHANE GROUTING PROGRAM In the event there are still leaking joints upon completion of the contact grouting program,HBI will utilize a hydrophilic polyurethane grout to seal existing pipe joints.The polyurethane grout will be injectedutilizing 5/8" injection ports and injected at the specific locations of the leaks. EXCEPTIONS TO THE SPECIFICATION HBI will provide a work plan that will include a detailed grouting program. The program will include a grout mix design,means and methods for injecting the grout. The grout mix will vary from the specification as well as the design strength. HBI is proposing void filling between the existing concrete pipe and the surrounding soil. It may not be possible or necessary to drill the probe holes to a depth of 3 feet.The constraints of the pipe may not allow , for this depending on what equipment is utilized for drilling the probe holes.The grout mixing and pumping equipment may deviate from the specification as well as injection pressures.The grouting program will need to be flexible and have the ability to be adjusted in the field depending the specific site conditions. UALITY ASSURANCE AND QUALITY CONTROL PROGRAM HBI will employ a full-time,qualified foreman/superintendent throughout the course of the project.A daily site report will also be produced describing each day's activities at the site. These forms will be made available to the Client on a daily basis. The client is free to employee a third party for observation and testing if so inclined but will bear all associated costs. HBI will develop a confined space work plan and a grouting work plan that will be submitted prior to the beginning of construction. ACCEPTANCE CRITERIA Acceptance of the project will be based on a successful grouting program based on HBI's inspection of all grout logs and daily site reports in combination with the client's acceptance of the same. The above information should be regarded as preliminary general guidance offered in good faith to improve the performance of the existing RCP. We cannot assume any responsibility for the performance of the RCP after the grouting as described above is completed. CONSTRUCTION SEQUENCE ' HAYWARD BAKER A KELLER COMPANY 1. A notice to proceed and written acceptance of this proposal has been issued to HBI. 2. HBI will provide a confined space and grouting workplan. 2. HBI will utilize the Texas 811 utility location system. 3. Crews,equipment and materials will be mobilized to the project site. 4. Performance of the work. 5.

Whether City or Surety completes the Work, Contractor shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds all claims, costs, losses and damages sustained by City arising out of or resulting from completing the Work, such excess will be paid to Contractor. If such claims, costs, losses and damages exceed such unpaid balance, Contractor shall pay the difference to City. Such claims, costs, losses and damages incurred by City will be incorporated in a Change Order, provided that when exercising any rights or remedies under this Paragraph, City shall not be required to obtain the lowest price for the Work performed. 4. Neither City, nor any of its respective consultants, agents, officers, directors or employees shall be in any way liable or accountable to Contractor or Surety for the method by which the completion of the said Work, or any portion thereof, may be accomplished or for the price paid therefor. 5. City, notwithstanding the method used in completing the Contract, shall not forfeit the right to recover damages from Contractor or Surety for Contractor's failure to timely complete the entire Contract. Contractor shall not be entitled to any claim on account of the method used by City in completing the Contract. 6. Maintenance of the Work shall continue to be Contractor's and Surety's responsibilities as provided for in the bond requirements of the Contract Documents or any special guarantees provided for under the Contract Documents or any other obligations otherwise prescribed by law.

Notwithstanding Paragraphs 15.02.13, Contractor's services will not be terminated if Contractor begins within seven days of receipt of notice of intent to terminate to correct its failure to perform and proceeds diligently to cure such failure within no more than 30 days of receipt of said notice. D. Where Contractor's services have been so terminated by City, the termination will not affect any rights or remedies of City against Contractor then existing or which may thereafter accrue. Any retention or payment of moneys due Contractor by City will not release Contractor from liability. E. If and to the extent that Contractor has provided a performance bond under the provisions of Paragraph 5.02,the termination procedures of that bond shall not supersede the provisions of this Article.

Contractor shall not be paid on account of loss of anticipated profits or revenue or other economic loss arising out of or resulting from such termination.

OSHA Regulations: 29 CER 1926, Subpart P - Excavation, Trenching and Shoring. [1926.652(c)(4)) 2. Contract Documents—Jacobs Engineering Group,Inc. 3. Geotechnical Report—None available. The excavation shoring system as shown on the attached drawing is acceptable for this project. Your use of S ft. trench boxes with a minimum uniform lateral earth pressure rating of 950 psf is suitable for the proposed boring pit/access shaft. If groundwater is present above the excavation bottom,appropriate dewatering techniques such as sumps or wellpoints may be required to maintain a stable working area. Employees may work in excavations where there is accumulated water or where water is accumulating if the shoring system is in place and the bottom of the excavation and exposed sides are stable. Water removal provisions shall be available to periodically remove excess accumulation of water(6 inches or greater). Water shall not be allowed to accumulate enough to require the use of safety harness or lifeline. You ace required to provide daily inspections by a competent person of the oxcavations, the adjacent areas,and protective systems. If the competent person finds evidence of a situation that could result in possible cave-ins,indications of failure of protective systems,hazardous atmospheres,or other hazardous conditions,exposed employees shall be removed from the hazardous area until the necessary precautions have been taken to ensure their safety. Your employees shall be protected from the hazard of cave-ins when enterhig or exiting the areas protected by the shoring.

Crews will grout each section of the RCP pipe until the void is fully grouted then moving to the next section of pipe and continuing the process in this sequence until the entire tunnel is grouted. (Votes From Grouting Performed Grout was injected starting from Danciger,the low end,and moving uphill towards the pond end. m The grout nozzle was inserted into the grout port in the top of the 54"RCP pipe and continued grouting until grout flowed out of the next upstream grout port or until refusal to accept additional grout occurred.The grout would flow in all directions from the grout port thereby filling any voids. The tunnel is a rock face hand mine installation and therefore there was minimum overcut throughout the tunneling installation. pR��y �.arrs S1r��rT Tivkt.(� . GrZouf �1�A�s;r;>r 5 gas/,� P.O.

See Figure 1 for vicinity map and plan of borings. Proposed invert depths will range from 10' to 15'. 2.0 SCOPE OF INVESTIGATION This report was prepared in accordance with our Proposal No. P09-0801 E-R1, dated August 20, 2009. The purposes of the study were to: 1) explore the subsurface conditions at the sites, 2) characterize the subsurface conditions by testing the physical and engineering properties of the underlying soil and rock strata and by observing groundwater conditions, 3) provide recommendations for the proposed improvements, and 4) provide comments related to temporary open cut trench excavations at the site. 3.0 FIELD OPERATIONS Fourteen (14) deep geotechnical borings and one (1) test pit were drilled at approximate locations shown on the Boring Location Diagram on Figure 1. The results of the boring program are presented on the Logs of Borings on Figures 2 thru 16. A key to the descriptive terms and symbols used on the logs is shown on Figures 17 and 18. A truck mounted drilling rig was used to advance the geotechnical borings and to obtain samples for laboratory evaluation. The test pit (TP-15) was drilled by hand along the creek bank using portable drilling equipment to evaluate soil and groundwater conditions and to determine rock depth in this area. Undisturbed specimens of the cohesive soils were obtained using standard, thin walled, seamless tube samplers. These specimens were extruded in the field, logged, sealed, and packaged in plastic sample bags to protect them from disturbance and maintain their i in-situ moisture content during transportation to our laboratory. The granular soils were sampled using split barrel samplers in connection with Standard Penetration Testing. The rock hardness and bearing capacity characteristics of the rock strata were evaluated by the Texas Department of Transportation Cone Penetration Test. This test consists of MAS-TEK ENGINEERING &ASSOCIATES E10-1103-02 PAGE 1 I measuring the penetration of a 3-inch diameter cone driven with a 170-pound hammer falling 24 inches. The results of these tests are reported on the boring logs. 4.0 LABORATORY TESTING Samples were examined at our laboratory by the project geotechnical engineer. Selected samples were subjected to laboratory tests under the supervision of this engineer. The in-situ unit weight, moisture content, liquid and plastic limits, and grain size characteristics of selected soil samples were tested. These tests were used to estimate the shear strength of the different soil strata and as an indication of the uniformity of the material. Hand penetrometer tests were also performed to provide an indication of the variation of soil strength with depth. Unconfined compression tests were performed on representative samples of the clay overburden soils. These results are presented on the Logs of Borings. The results of sieve analyses are shown on the boring logs and on Figures 19 and 20. The results of sulfates determinations are reported on Figure 24. 5.0 SURFACE CONDITIONS 5.1 SITE GEOLOGY As shown on the Tarrant County sheet of the Geologic Atlas of Texas, the alignment extends across three (3) geologic formations. the Grayson Marl/Main Street Limestone Formation, the Woodbine Formation and the Pawpaw Formation. Hard Limestone and sandstone can be present at shallow depths within these formations. Hard rock outcrops are also possible as well as large hard sandstone boulders. Existing fill was observed in some areas across the site of the sedimentation basins. Existing fill was encountered to depths of up to 10 feet in some of the borings. The fill may contain large concrete and rock boulders in some areas. Hard rock was encountered at depths as shallow as 3 to 6 feet in the actual borings and test pit but could be present at shallower depths in rock outcrops in some areas. 5.2 SUBSURFACE CONDITIONS Subsurface conditions encountered in the borings, including descriptions of the various strata and their depths and thicknesses, are presented on the Logs of Boring. Note that depth on all borings refers to the depth from the existing grade or ground surface present at the time of the investigation. Boundaries between the various soil types are approximate. MAS-TEK ENGINEERING &ASSOCIATES E10-1103-02 PAGE 2 As shown on the Tarrant County sheet of the Geologic Atlas of Texas, the alignment extends across three (3) geologic formations: the Grayson Marl/Main Street Limestone Formation, the Woodbine Formation and the Pawpaw Formation. Hard Limestone and sandstone can be present at shallow depths within these formations. Hard rock outcrops are also possible as well as large hard sandstone boulders. Existing fill was observed in some areas across the site of the sedimentation basins. Existing fill was encountered to depths of up to 10 feet in some of the borings. The fill may contain large concrete and rock boulders in some areas. Hard rock was encountered at depths as shallow as 3 to 6 feet in the actual borings and test pit but could be present at shallower depths in rock outcrops in some areas. Shallow rock outcrops and existing fill were observed around the site of the proposed basins. As indicated on the boring logs, existing fill soils were encountered in various areas. At Borings B2 and B3, the fill was encountered to depths of up to 10 feet. At Borings B2 and B3, the deeper existing fill consists of water-bearing fill materials containing varying amounts of sand, gravel and broken asphalt. 5.3 GROUNDWATER The borings were advanced with continuous flight auger drilling equipment. This method allows relatively accurate groundwater observations to be made while drilling. Groundwater seepage was observed in some borings at depths ranging from about 2' to 10' below the existing ground surface at the time of this investigation. See boring logs. This groundwater is perched within the existing fill and is present within the underlying granular soils overlying the rock formations. Groundwater is also present within the jointed manly clay and fractured rock. The subsurface water conditions are subject to change with variations in climatic conditions and are also functions of subsurface soil conditions, rainfall and water levels within nearby creeks, ponds and basins. It should be anticipated that groundwater seepage will be encountered at shallower depths in all areas after periods of rain. 6.0 UTILITY EXCAVATIONS 6.1 TRENCH EXCAVATIONS It is understood that open cut trench excavations will be performed at this site and that trench depths will typically be on the order of 10 to 15 feet below the existing ground surface. MAS-TEK ENGINEERING &ASSOCIATES El0-1103-02 PAGE 3 bracing may be determined as presented on Figures 22 and 23. It should be recognized that pressures are not included from hydrostatic pressures, surcharge loads, or traffic live loads at trench side walls, dynamic bads, and vibration, which if present, must be included in bracing design. In lieu of a shoring system, a trench shield consisting of a prefabricated rigid steel unit adequate to withstand anticipated lateral pressures may be used. 6.4 DE►!tlATERING Groundwater was encountered in the test borings during drilling as indicated on the boring logs. Groundwater will be encountered at relatively shallow depths in some areas, particularly after periods of heavy rain. See Section 5.3. In areas where groundwater is encountered, a system of well points, ditches, sumps, and pumping will be required to provide groundwater control. The design of the actual dewatering system required is the contractor's responsibility. This includes the control of tail-water flow through previous backfilled sections. 6.5 CONSTRUCTION CONSIDERATIONS The following guidelines are presented to aid in the development of the excavation plans: Surface areas behind the crest of the excavations should be graded so that surface water does not pond within 15 feet of the crest, nor drain into the excavation. Heavy material stockpiles should not be placed near the crest of slopes per OSHA requirements. Similarly, heavy construction equipment should not pass over or be parked within 5 feet of the crest. The crest of slopes should be continually monitored for evidence of movement or potential problems. Freestanding slopes will become less stable when influenced by groundwater or saturation by rain. 6.6 TRENCH BACKFILL The excavated soils can be used for trench backfill. Use of rock fragments greater than six (6) inches in any dimension should be prohibited, since attaining uniform moisture and density without voids would be difficult. The backfill should be placed in thin compacted lifts as specified below. The fill materials should be free of surficial vegetation or debris. MAS-TEK ENGINEERING &ASSOCIATES E10-1103-02 PAGE 5 i I Clay and silty clay fill soils having a PI greater than 25 should be placed in 8 inch horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method. The clay and sandy clay should be compacted at optimum to +4% above the optimum moisture content. Silty clay and calcareous clay fill soils having a PI of less than 25 should be placed in 8 inch horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method. These lower PI soils should be compacted at -2% to +2% of optimum moisture. The on-site limestone may be used as utility trench backfill. Broken limestone should be adequately crushed to where individual rock fragments have a diameter of less than 6 inches. The crushed limestone should be placed in 8 inch horizontal loose lifts and compacted to at least a minimum of 95 percent of the maximum dry density as determined by ASTM D-698 test method at -2% to +2% of optimum moisture. The limestone materials should be crushed using a compactor of sufficient size and weight to crush the rock. Note: For fill depths below 15 feet and 25 feet depths respectively, the compaction level should be increased to 98% and 100% ASTM D698, respectively, where it is desired to reduce post-construction settlements. 6.7 CORROSION CONSIDERATIONS Based on the results of sulfates testing, sulfates levels of the on-site soils are very high and exceed 40,000 ppm in some areas. Appropriate measures should be taken during design of the concrete mix design for buried concrete per ACI. The clay and manly clay soils are also considered to be highly corrosive to buried metals. 7.0 INSPECTION AND TESTING Many problems can be avoided or solved in the field if proper inspection and testing services are provided. It is recommended that all excavation and fill placement be monitored by Mas-Tek Engineering. This includes placement and compaction of trench backfill. Inspection should be performed prior to and during concrete placement operations. i MAS-TEK ENGINEERING &ASSOCIATES El0.1103-02 PAGE 6 As indicated on the Boring Logs, soil and rock conditions will vary considerably at the invert depths. Subsurface conditions will range from water bearing granular soils, hard to very hard fractured limestone, very stiff to hard jointed clay, jointed marly clay and fill soil containing water bearing granular layers. The clay soils are jointed and fissured. For trench excavations to any depth at this site, it will be necessary to employ either sloped excavations or temporary bracing due to unstable soil or unstable rock (sand, gravel, fill soil, jointed marly clay, weathered limestone), For trench excavations to any depth at this site, it will be necessary to employ either sloped excavations or temporary bracing, regardless of the soil conditions encountered. General guidelines for the design of these two alternatives are discussed in the following sections. 6.2 OPEN CUTS Recommended slope ratios for the respective soil conditions are presented graphically on Figure 21. Trench excavations to any depth at this site in unstable soil conditions should be cut back as described above. It should be recognized that free standing slopes will be less stable when influenced by groundwater or saturated by rain. Surcharge loads, such as those resulting from excavation spoil, or equipment, should be placed no closer than two feet from the crest of the slope, or in accordance with OSHA regulations. Vehicle traffic should be maintained at least five feet from the edge of the crest. Excavations will encounter fill soils placed during previous construction activities and groundwater seepage. Where encountered, these soils should be sheeted, shored, and braced, or laid back on slopes no steeper than 1.5 (H): 1(V). The contractor will need to take measures to avoid undermining and damaging the existing underground utilities and any adjacent pavements or structures. 6.3 TRENCH BRACING 1 BORE PIT SHORING Where site limitations require excavations to have vertical side walls, an internal bracing system will be necessary. Bracing may consist of timber or steel shoring or manufactured steel trench braces.

The possibility always exists that the subsurface conditions at the site may vary somewhat from those encountered in the boreholes. The number and spacing of test borings were chosen in such a manner as to decrease the possibility of undiscovered abnormalities, while considering the nature of loading, size, and cost of the project. If there are any unusual conditions differing significantly from those described herein, Mas-Tek Engineering should be notified to review the effects on the performance of the recommended foundation system. The recommendations given in this report were prepared exclusively for the use of the Client and their consultants. The information supplied herein is applicable only for the design of the previously described development to be constructed at locations indicated at this site and should not be used for any other structures, locations, or for any other purpose.

DISCUSSION: The purpose of this Mayor and Council Communication is to ratify an emergency construction contract for repair of tunnel storm drain installed as part of the Eastern Hills Drainage Improvements Project, Phase 2. When sinkholes began to appear in a residential yard in the vicinity of the tunnel,a repair was undertaken to address them,but additional sinkholes began to develop under an existing concrete channel.Due to the continuing threat to public safety,the concrete channel,and private property caused by the sinkholes,it was in the best interest of the City to commence comprehensive repairs as soon as possible.An emergency procurement authorization was approved,and Jacobs Engineering Group,the design engineer,prepared a Best Value Request for Proposal,which was submitted to three contractors. Only one contractor,Hayward Baker, Inc.,responded with a proposal.Negotiations resulted in an effective work scope at a cost of$227,418.00.Staff believes that this is a fair and reasonable price for the work to be performed.Hayward Baker, Inc.,began the repair work on April 1,2019,and expects to be complete in May 2019. This project is located in COUNCIL DISTRICT 4 MWBE Office:A waiver of the goal for MBEISBE subcontracting requirements was requested by the Department and approved by the MWBE Office,in accordance with the MWBE or BIDE Ordinance, because the public or administrative emergency exists which requires the goods or services to be provided with unusual immediacy. This contract legally does not require City Council approval. FISCAL INFORMATIONXERTIFIGATION: The Director of Finance certifies that funds are available in the current capital budget,as appropriated,of the Stormwater Capital Projects Fund,and that prior to an expense being made,the department has the responsibility to validate the availability of funds.
