PRE-OUALIFICATION REOUIREMENT: All contractors submitting bids are required to be pre-qualified by the Forth Worth Water Department prior to submitting bids.

Any proposals submitted by a non-pre-qualified bidder shall be returned unopened, and if inadvertently opened, shall not be considered. (g) The City will attempt to notify prospective bidders whose qualifications (financial or experience) are not deemed to be appropriate to the nature and/or magnitude of the project on which bids are to be received. Failure to notify shall not be a waiver of any necessary pre-qualification. 2.

B.2-B.5 w Report No. 1401-0124 1.0 INTRODUCTION �LGRO �� 1.1 Project Description �` This data report presents the results of the subsurface exploration for sanitary sewer rehabilitation � and pavement repairs (Water Project No. PS46-070460172890, DOE No. 0789) in Fort Worth, Texas. The project is locatad at two separate locations. One site is located east of the intersection of Briardale Road and Business Highway 287 in southeast Fort Worth (Borings B-1, B-2, and B-3). R" The other site is located near the intersection of Forest Park Boulevard and Park Hill Drive in southwest Fort Worth (Borings B-4, B-5, B-6, and B-7). � The overall project will consist basically of new construction of a gravity flow sewer line. This subsurface exploration data report addresses a section of L-5125 for a proposed 8-inch sanitary � sewer (Borings B-1, through B-3) and a section of M-74R for a proposed 10-inch sanitary sewer (Borings B-4 through B-7), as shown on the attached Plan of Borings, Plate A.1. � During the time of our field exploration, the Briardale Road site consisted of mainly a neighborhood ' setting (near Borings B-1 through B-3) and the Forest Park Boulevard site consisted mainly of small �. retail and apartments (near Borings B-4 through B-7). All the borings were drilled on asphalt paved 4, roads. 1.2 Purpose and Scope The purpose of this subsurface exploration data report has been to determine the general subsurface soil and ground water conditions and present laboratory test results of the subsurFace materials encountered. It was recognized at the start of the data report that the scope of services was not intended to fully define the variability of the soil types and conditions which could be present over the entire site area or provide geotechnical engineering recommendations for the sewerline, manholes, or any other structures. To accomplish its intended purposes, the data report has been conducted in the following phases: (1) drilling sample borings to determine the general subsurface conditions and to obtain samples for testing; and (2) performing laboratory tests on selected samples to determine pertinent engineering properties of the subsurface materials. The design is currently in progress and the locations and/or elevations of sewerline and structures associated with the sewerline could change. 1 Report No. 1401-0124 1.3 Data Report Format The text of the data report is contained in Sections 1.0 through 6.0. A list of references is presented immediately following the end of the data report text. The reference list contains general references which were used during this data report, but are not specifically cited in the text. All plates and large tables are contained in Appendices A and B. The alpha-numeric plate and table numbers identify the appendix in which they appear. Small tables of less than one page in length may appear in the body of the text and are numbered according to the section in which they occur. Units used in the data report are based on the U.S. Customary (foot-pound-second) system and may include tons per square foot (tsfl, kips (1 kip = 1,000 pounds), kips per square foot (ksfl, pounds per square foot (psfl, pounds per cubic foot (pcfl, and pounds per square inch (psi). 2.0 FIELD EXPLORATION Subsurface materials at the project site were explored by 7 borings drilled to depths of 15 to 25 feet in the area of the proposed sewerlines. The borings were drilled June 22 and 24, 1998, at the approximate locations shown on the Plan of Borings, Plate A.1. The boring locations were selected by Dunaway Associates, inc. The boring logs are included on Plates A.4 through A.10 and boring log terms, symbols, and general notes are provided on Plates A.2 and A.3. � Undisturbed samples of cohesive soils were obtained with nominal 3-inch diameter thin-walled (Shelby) tube samplers at selected depths. The tube is hydraulically pushed into the soil by the drilling rig. The soil samples were extruded from the tube in the field, logged, and packaged to limit � loss of moisture. � The unconfined compressive strength of cohesive soil samples was estimated in the field using a � calibrated hand (pocket) penetrometer. The results of these tests, in tsf, are listed at the various " sample depths in the appropriate column on the logs. The maximum capacity of the penetrometer is -- 4.5 tsf. When the capacity is exceeded, the value is listed as 4.5+. � � � � To evaluate the relative density and consistency of the harder formations, a modified version of the Texas Cone Penetration test was performed at selected locations. Texas Department of Transportation (Tx-Dot) Test Method Tex-132-E specifies driving a 3-inch diameter cone with a 170- pound hammer with a free fall of 24 inches. This results in 340-foot pounds of energy for each blow. This method was modified by utilizing a 140-pound hammer with a free fall of 30 inches. This results in 350-foot pounds of energy for each hammer blow. In relatively soft (soil) materials, the 2 � �� t� � Report No. 1401-0124 GRO � penetrometer cone is driven 12 inches and the number of blows is shown at the various test depths on the boring log. In hard materials (rock or rock-like), the penetrometer cone is driven a total of 100 blows. The penetration in inches for the 100 blows is shown at the various test depths on the boring logs. Disturbed samples of noncohesive granular or stiff to hard cohesive materials were obtained at selected depths utilizing a nominal 2-inch O.D. split-barrel sampler in conjunction with the Standard Penetration Test (SPT). The SPT utilizes a 140-pound hammer with a free fall of 30 inches, to drive the split-barrel sampler. The number of blows required for 12 inches of penetration after an initial seating interval of 6 inches, is shown as the SPT "N" value at the appropriate depth on the logs of borings. If less than 6 inches of penetration is achieved, either during or following the seating interval, the test is terminated and the number of inches achieved during the 50 blows is shown on the boring log. Ground-water observations during and upon completion of drilling of the borings are shown on the �'• boring log. Upon completion of the borings, the boreholes were backfilled with soil cuttings and ' plugged at the surface by hand tamping and the existing asphalt pavement was patched with pre- -, mixed asphalt. 3.0 LABORATORY TESTING Routine laboratory tests were performed on specimens from selected samples recovered from the borings. These tests included moisture content, liquid and plastic limits, percent passing the No. 200 sieve, unit dry weight, Torvane shear, and unconfined compressive strength The results of these tests are shown at the respective depths in the appropriate columns on the boring logs. The results of the unconfined compressive strength tests, along with stress-strain curves, are also presented on Plates 6.2 through 6.5 The above laboratory tests were performed in general accordance with applicable ASTM or U.S. Army Corps of Engineers procedures, or generally accepted practice. 4.0 SUBSURFACE EXPLORATION 4.1 Geology Based on available geological maps and field observations, the Briardale Road site (Borings B-1 1 through B-3) is located within the Pawpaw Formation, Weno Limestone, and Denton Clay undivided and the Grayson Marl and Mainstreet Limstone undivided geological formations. The Forest Park �. 3 � Report No. 1401-0124 GRO � Boulevard site (Borings B-4 through B-7) is located within the Fort Worth Limestone and Duck Creek Formation undivided and the Pawpaw Formation, Weno Limestone, and Denton Clay undivided geologic formations. 4.2 Subsurface Stratigraphy Specific types and depths of subsurface strata encountered at the boring locations are shown on the boring logs in Appendix A. The generalized subsurface stratigraphy encountered in the borings is discussed below. Overburden soils encounte�ed in the borings consist of lean clay, lean clay with sand, clayey sand with gravel, and sandy lean clay. The thickness of the overburden soils at the boring locations at the Briardale site ranges from approximately 6.0 to 25.0 feet. The thickness of the overburden soils at the Forest Park site ranges from approximately 2.0 to 22.0 feet. The clayey soils are generally stiff to hard (soil basis) with pocket penetrometer readings of 1.75 to over 4.5 tsf and torvane shear strength values ranging from 0.5 to 2.2 tsf. Liquid limit and plasticity index values ranged from 20 to 59, and 10 to 36, respectively. Percent passing the number 200 mesh sieve ranged from 25 to 86. Unit dry weight values ranged from 97 to 122, and moisture contents ranged from 8 to 26. The tan weathered limestone at both sites was hard to very hard (sedimentary rock basis) with THD cone penetrometer values ranging from 0.125 inches to 1 inch per 100 blows. The gray limestone at both sites was very hard (sedimentary rock basis) with THD cone penetrometer values ranging from 0 inches to 0.167 inches per 100 blows. 4.3 Ground-Water Observations � Ground water was not observed in the borings at the time of the field exploration on June 22 and 24, ` 1998. It is not uncommon, however, to find ground water (perched water tables) along the surface of —. the limestone encountered in the borings with the amount dependent upon area rainfall. Fluctuations of the ground-water level can occur due to seasonal variations in the amount of rainfall; site topography and runoff; hydraulic cond�ctivity of soil strata; and other factors not evident at the time the borings were performed. The possibility of ground-water level fluctuations should be considered when developing the design and construction plans for the project. 4 � - - -- --- -- - ---- Report No. 1401-0124 ;;Rp .�` � � r" . Water traveling through the soil (subsurface water) is often unpredictable. This could be due to seasonal changes in ground water and due to the unpredictable nature of ground-water paths. � Therefore, it is necessary during construction for the contractor to be obsenrant for ground-water a�" seepage in excavations in order to assess the situation and take appropriate action. 5.0 CONSTRUCTION OBSERVATIONS In any subsurface exploration data report, the recommendations are based on a limited amount of -- information about the subsurface conditions. The engineer must assume the subsurface conditions _ are similar to the conditions encountered in the borings. However, quite often during construction, � anomalies in the subsurface conditions are revealed. Therefore, rt is recommended that Fugro be retained to observe actual subsurface conditions in the excavations and perform materials evaluation � and testing during the construction phase of the project. This enables Fugro to be available to evaluate unanticipated conditions, to conduct additional tests if required and, when necessary, to recommend solutions to unanticipated conditions. It is proposed that construction phase observation and materials testing commence by Fugro at the outset of the project. Experience has shown that the most suitable method for procuring these services is for the owner or the owner's design engineers to contract directly for these services, rather than requiring the contractor to contract for construction matenals testing services. � 6.0 REPORT CLOSURE � The borings for this data ��port were staked by Fugro, using approximate taping methods from existing topographic features. The actual boreholes were placed as close as practical to the staked � locations. The elevations of the borings were taken off the preliminary construction plans and profiles provided by Dunaway Associates, Inc., dated October 3, 1997. The locations and elevations of the borings should be considered accurate only to the degree implied by the methods used in their � determination. The boring logs shown in this data report contain information related to the types of y soil encountered at specific locations and times and show lines delineating the interface between these materials. The logs also contain our field representative's interpretation of conditions that are � believed to exist in those depth intervals between the actual samples taken. Therefore, these boring `` logs contain both factual and interpretive information. Laboratory soil classification tests were also � performed on samples from selected depths in the borings. The results of these tests, along with visual-manual procedures were used to generally classify each stratum. Therefore, it should be ' � 5 � i A - -- - - --- -- - ---------- ------- ---- ---- Report No. 1401-0124 �p�p � - � id- — ----- -- _ __ I � _ understood that the classification data on the logs of borings represent visual estimates of classifications for those portions of each stratum on which the full range of laboratory soil classification tests were not performed. It is not implied that these logs are representative of �" subsurface conditions at other locations and times. � With regard to ground-water conditions, this data report presents data on ground-water levels as they were observed during the course of the field work. In particular, water level readings have been �"" made in the borings at the times and under conditions stated in the text of the data report and on the boring logs. It should be noted that fluctuations in the level of the ground-water table can occur with passage of time due to variations in rainfall, temperature and other factors. Also, this data report � does not include quantitative rnformation on rates of flow of ground water into excavations, on pumping capacities necessary to dewater the excavations, or on methods of dewatering excavations. I� Unanticipated soil conditions at a construction site are commonly encountered and cannot be fully predicted by mere soil samples, test borings or test pits. Such unexpected conditions frequently require that additional expenditures be made by the owner to attain a properly designed and I�' constructed project. Therefore, provision for some contingency fund is recommended to ' accommodate such potentio! extra cost. � The information contained in this data report is based on site conditions as they existed at the time of our field exploration. If, during construction, different subsurface conditions from those encountered � in our borings are observed, or appear to be present in excavations, we must be advised promptly so that we can review these conditions. If there is a substantial lapse of time between submission of this data report and the start of the work at the site, if conditions have changed due either to natural � causes or to construction operations at or adjacent to the site, or if finish grades are changed, we urge that we be promptly informed and retained to review our data report considering the changed � conditions and/or time lapse. The scope of our services did not include any environmental assessment or investigation for the � presence or absence of wetlands or hazardous or toxic materials in the soil, surface water, ground water or air, on or below or around the site. The scope of our seniices also did not include any � geotechnical recommendations, evaluation of the site for suitability for the intended construction or use, other than those items specifically addressed in this data report.
