In preparing this proposal, we have reviewed the geotechnical information we have in the vicinity, proposed soil boring location plan (111),geotechnical report request (dated 04/21/2022, revised) provided by the client in their email on June 30, 2022, and geotechnical engineering report (Project No.1637, dated May 11, 2022) completed by ECS. PROJECT BACKGROUND Existing Site Conditions: The project site is located at the northeast corner of N Forest Park Boulevard and West 5th Street in Fort Worth, Texas (GPS: 32.7529 N, 97.3439 W). ECS did not visit the site prior to preparing this proposal. Based on Google maps as well as previous site visit for preparation of geotechnical engineering report (Project No.1637, dated May 11, 2022), existing structure and pavements are present at the site. Project Description: Based on the proposed soil boring plan (111, prepared by JQ Engineering, dated January 19, 2022) and geotechnical report request (prepared by JQ Engineering, dated April 21, 2022, revised), we understand the project will consist of relocation of the Fort Worth City Hall to the Pier 1 Imports Building, 100 Pier 1 Place, Fort Worth, Texas. ECS completed geotechnical investigation for relocation of the Fort Worth City Hall in May 2022 (ECS Project Number 63:1637, dated May 11, 2022).The scope of the project has since been expanded; a new garage will be built adjacent to the existing garage.The garage will be located on the west side of the current garage within the existing surface parking lot. The garage is anticipated to be a three-bay configuration with flat levels on the exterior and a center ramp and be four-levels in height to match the existing. The new garage will be separated from the existing garage with an expansion joint. The client is requesting additional geotechnical services to supplement the previous reports. 2621 White Settlement Road, Fort Worth, TX 76107 • T: 682-350-2250 • www.ecslimited.com ECS Capitol Services, PLLC • ECS Florida, LLC • ECS Mid-Atlantic, LLC • ECS Midwest, LLC • ECS Southeast, LLP • ECS Southwest, LLP ECS SOUTHWEST, LLP Foundation support for concentrated column loads of up to 900 kips for the new four level parking structure. Soil preparation for slab-on-grade construction required to limit heave or settlement to 1 inch for the new parking structure. This should pertain to the ground floor and ramp between the first and second levels. SCOPE OF SERVICES In order to evaluate the subsurface conditions for the proposed development, a subsurface exploration consisting of a series of soil borings will be performed. Our integrated services will include drilling borings by drilling crews based on instructions provided by ECS. Our services will also include laboratory testing of representative soil samples, and engineering analyses presented in a site-specific engineering report. As requested, we will perform a total of four (4) borings. The borings will be extended to the proposed depths unless auger refusal causes them to be terminated at a shallow depth. Upon completion of drilling operations, the samples will be returned to our laboratory in Fort Worth, Texas for further identification and testing. The following figure provides our proposed boring locations planned at the site: 09 Ir 4 i , l I I f � ❑. ., 9 WEST ST_H_STR_EET '"` - Approximate Boring Locations Previously Drilled Boring Locations Field Exploration Our field exploration will include: a. Field locate borings by handheld GPS unit. Elevations will be interpolated from civil drawings or referenced from published topographical maps. b. Mobilize a truck mounted drilling rig to the site. c. Perform four (4) borings. The borings will be drilled to a depth of about 70 (or 20 feet into competent bedrock) below existing site grades within the proposed parking garage footprint. ECS Proposal No:63:2410-GP Page 1 2 E9 ECS SOUTHWEST, LLP d. Obtain representative soil samples by means of the split-barrel and Shelby tube sampling procedures in accordance with ASTM Specifications D-1586 and D- 1587, respectively. e. Texas Cone Penetrometer tests will be performed to evaluate the load carrying capacity of the bedrock encountered in the borings. These tests will be performed in general accordance with test method Tex-132-E in the Texas Department of Transportation (TxDOT) Manual of Testing Procedures. f. Measure the depth of groundwater at each boring at the time of drilling and prior to backfilling. Laboratory Testing Laboratory testing of representative soil samples will be performed to determine physical and engineering properties of the soil. The laboratory testing will include the following: • Moisture content • Atterberg limits • Passing No. 200 sieve • Overburden swell • Unconfined Compression Strength Engineering Report Upon completion of the field exploration, laboratory testing, and engineering analyses, we will prepare a written engineering report that will include: a. A review of published soils mapping and/or geologic information. b. Observations from our site reconnaissance and personnel on the drill rig, including current site conditions, surface drainage features, and surface topographic conditions, and/or available satellite imagery. c. A description of the field exploration and laboratory tests performed. d. Final logs of the soil borings in accordance with industry standard practices for geotechnical engineering. A Boring Location Plan will be included. e. The results of the laboratory tests will be plotted on the final exploration logs and/or included on separate test report pages. f. Discussion of the subsurface materials encountered along with groundwater conditions observed. Subsurface cross sections/profiles will be included that graphically represent the subsurface conditions. g. Geotechnical design parameters for deep foundations for new Parking Garage Structure. This will also include estimates of predicted foundation movement and soil moduli. h. Discussion of earthwork construction considerations for compaction, reuse of soils, groundwater, expansive soils, shallow rock, drainage, or other considerations. i. Recommendations for seismic site classification in accordance with the International Building Code (IBC 2012/2015). This analysis will be based on the Standard Penetration Test (SPT) method. UTILITY CLEARANCE Per state law, we will contact Texas 811 to locate underground utilities at the site. Typically, Texas 811 will not locate utilities beyond the point of distribution meters. The risk of hitting utilities that Texas 811 did not mark can be reduced by engaging a private utility locating service. The risks include hitting electric lines, electrocution, gas explosions, loss of services to businesses, and fiber optic lines can result ECS Proposal No:63:2410-GP Page 13 E9 ECS SOUTHWEST, LLP in tremendous costs for lost business, interruption of service, and repair along with potential legal liability. Private utility locator services can identify utilities that incorporate significant iron content in the conduit materials. However, utilities that are more difficult to detect are utilities without significant ferrous (iron) content which includes most sanitary sewer alignments, copper or PVC water lines, fiber optic lines without tracer ribbons, copper electric lines with no surface exposure, drainage tiles/pipes, irrigation lines, etc. Using a private utility locator does not guarantee that all utilities will be identified. However,this service lowers the risk and potential liability of the client, while also protecting the safety of our field exploration crews. We will coordinate our exploration locations around marked utilities, and utilities pointed out to us by the owner/client. However, we will not be responsible for any utilities not marked or not pointed out to us by the landowner or client. For this site, we recommend the use of a private utility locator. We have included private utility locate services in our cost estimate for a lump sum fee of$800.00. SITE DEPARTURE CONDITIONS Upon completion of subsurface exploration drilling, we will backfill each of the excavations with the excavated soil remove excess spoils. In pavement areas, we will patch the surface with concrete of an equivalent or greater thickness. In pavement areas, we will patch the surface with concrete of an equivalent or greater thickness. Typically, we will not provide site repairs beyond what is outlined above unless specifically contracted. Please note that some disturbance to off-pavement, gravel covered, grass covered areas, including the possible cutting of trees, running over of brush and understory in wooded areas might occur. We will attempt to limit such disturbance; however, we have not budgeted for site repairs including filling of tire ruts, seeding of lawn areas, replacement of bushes or the planting of trees, etc. If necessary, additional site repairs can be provided at an additional cost. Based on the scope of work outlined herein, ECS will provide our geotechnical services for a lump-sum fee of$21,655.00. Please see the attached the cost estimate. Our fee assumes that the site is accessible to a truck-mounted drill rig. If additional services are requested or required based on differing site conditions, we will contact you for verbal and written authorization to proceed with the additional services. SCHEDULE We have assumed that the client will assist in accessing the site (with the current site owners/occupants). We anticipate being able to mobilize to the site within three to four weeks after authorization to proceed, notification that on-site personnel if any has been made, and upon clearing utilities. ECS Proposal No:63:2410-GP Page 14 ECS SOUTHWEST, LLP Our ability to access the site and perform the field exploration may be impacted by precipitation, excessive temperatures, or other atmospheric conditions. Field exploration will be performed during normal business hours Monday through Friday. If work needs to be performed at night work or on weekends,there will be an additional fee. We anticipate that the drilling operations will require three to four days, and that the laboratory testing, will require about 1 week, followed by our engineering analyses. For time budget purposes, the entire scope should take about 6 to 7 weeks from initial authorization through final report submission. If there is a specific due date for the report, please let us know. Verbal comments on findings can be provided within 1 week of completion of the borings, if requested. CLOSING If other services are required because of unexpected field conditions, or because of a request for additional services, they will be invoiced in accordance with a negotiated fee. Before modifying or expanding the extent of our exploration program,we will contact you for your review and authorization. Our"Terms and Conditions of Service," are an integral part of our proposal. Our insurance carrier requires that we receive written authorization prior to initiation of work, and a signed contract prior to the release of any work product. This letter is the agreement for our services. Your acceptance of this proposal may be indicated by signing and returning a copy of this proposal to us. We are pleased to have this opportunity to offer our services and look forward to working with you on the project. Respectfully submitted, ECS SOUTHWEST, LLP *44417L- Ishtiaque Hossain, Ph.D., P.E.
