ASSOCIATED TESTING IG, A B 0 f l AVT 0 I[1 II I[ Ali • Subsurface soil and groundwater conditions 3143 Yellowstone Blvd, Houston, Texas 77054 Tel: (713) 748-3717 Fax: (713) 748-3748 • Geotechnical design recommendations include site and subgrade preparation after removal of existing pavement, fill and backfill placement, and subgrade and compaction requirements on road pavements and driveways along project alignments if any. • Control of groundwater. • Constructability issues. • Recommendation for outflow structures including RCP & RCB. An electronic copy of the draft report will be initially submitted. Once we have received HALFF Associates, Inc. Consulting Engineers and the Harris County Engineer's review comments, an electronic copy of the final report will be issued incorporating the comments. Cost Estimate Based on the scope of work outlined above, we estimate the cost for the field, laboratory, and engineering services for the geotechnical services presented in this proposal to be $59,794.00 (including pavement coring and patching) The cost estimates using the estimated project quantities and requirements are presented in the enclosed Itemized Geotechnical Fee Estimate spreadsheet. This estimate assumes: that underground utilities at proposed boring locations will be cleared by Texas 811 Call Service and/or private property maintenance personnel; boring locations and elevations will be surveyed by others; that the sites will be accessible to our truck -mounted equipment; and environmental sampling/ handling/ transportation/ disposal are not in the scope of this project. Permission/permit to access the site, if needed, will be arranged by others at no cost to ATL. Proiect Schedule Upon written notice, from the County Engineer, to proceed with the geotechnical study plan, the geotechnical consultant will begin the geotechnical study. Once this project is authorized and Notice to Proceed is received, and after HALFF Associates, Inc. conducted the initial site conditions survey and layout of the preliminary locations for soil borings, ATL personnel will conduct a site visit within 3 days to visit the proposed boring locations and assess the site logistics. The coring/boring locations will be field adjusted according to the site conditions (including traffic conditions, existing utilities, etc.). ATL will call Texas 811 Call Services to request utility clearance for the coring/boring locations (which requires at least 3 days for clearance). ATL plans to conduct the soil borings in about 2 days after HALFF Associates, Inc. has completed the existing conditions survey. The laboratory soil testing will take about one week to complete. ATL will submit a draft report in about 3 to 4 weeks. \\Atl-server\geo\Proposal\2022\GP22-0501 - Brookglen Subdivision - La Porte\GP22-0501 - Brookglen Subdivison - Rev2.doc 11
