Cost Estimate for Geotechnical Engineering Services rr <br />Drainage Ditch Improvements — Battleground Estates n La Porte, Texas <br />July 5, 2011 m Terracon Document No. P91110111 <br />Page 2 <br />Field Program, As requested, the field program is planned to consist of drilling three (3) test borings <br />to depths of 15 feet below existing grade along the proposed drainage ditch Improvements, and one <br />test boring to a depth of 10 feet below existing grade (top of paving) for the roadside ditches along <br />Bois D'Arc Drive. The total drilling footage is planned to be 55 feet. <br />Soil samples will generally be collected utilizing either open -tube samplers or Standard Penetration <br />Test. Once the samples have been collected and classified in the field, they will be properly <br />prepared and placed in appropriate sample containers for transport to our laboratory. We can locate <br />the borings by measuring distances from existing streets and /or site features shown on the provided <br />drawings, without the use of survey equipment. Boring depths will be measured from existing grade. <br />The boring locations will be backfilled with soil cuttings and patched with asphaltic concrete (where <br />needed). <br />The drilling services for this project will be performed by a drilling subcontractor or Terracon's in- <br />house drillers. We plan to use all - terrain vehicle (ATV) - mounted drilling equipment to access the <br />boring locations. This scope of services assumes that the site can be accessed during normal <br />business hours and does not include services associated with site clearing, location of on -site <br />underground utilities, or the use of special equipment for unusually soft or wet surface conditions. If <br />such conditions are known to exist on the site, Terracon should be notified so that we may adjust <br />our scope of services and estimated fees, if necessary. <br />Terracon will notify DIG TESS, a free utility locating service, to help locate public utilities within the <br />vicinity of the site. If underground utilities are known to exist within the site, Terracon should be <br />notified so that we may review utility plans and help avoid the existing lines. Terracon cannot be <br />responsible for damage to unmarked and/or unlocated utilities for which we are unaware or that are <br />improperly located. <br />Laboratory Testing. The sample classifications will be reviewed and a laboratory testing program <br />will be assigned which will be specific to the project requirements and the subsurface conditions <br />observed. The testing program could Include, but may not be limited to, moisture contents, unit dry <br />weights, Atterberg limits, compressive strength tests and grain -size analyses. <br />Geotechnical Engineering Report. The project will be supervised by a professional Geotechnical <br />Engineer licensed in the State of Texas. Based on the results of our evaluation, an engineering <br />report will be prepared which details the results of the testing performed and provide Boring Logs <br />and a Boring Location Plan. The report will also provide Geotechnical Engineering <br />recommendations which will address the following; <br />Groundwater Control; <br />* Excavation and sideslope considerations; and <br />e Erosion protection considerations. <br />Reliable a Rosponslve n Convenient m I11110vative <br />
