Tax 2011C-CN120222In accordance with the attached specification, URETEK will perform the following operations: 1. Work schedule to complete the entire project is estimated at 4 work days with one truck and crew. 2. Profile roadway of the test sections listed below. 3. Perform Dynamic Cone Penetrometer (DCP) tests, one or two at each location. 4. Inject the following test sections listed below. All locations are planned for full panel injections and injections in the trench alongside the pipe as originally planned — no partial panels. 5. Location 1 — all three water lines involved. Both sides of the street — full width. North Side — 36' long x 35' wide — centered on the air relief valve system. South Side — 44' long x 25' wide 6. Location 2 — Drain box & Storm Drain Line. South Side only — 30' long x 25' wide — full width. 7. Location 3 — Good pavement — no relocation of utilities was involved. South Side only — 21' long x 25' wide — full width. 8. Drill out top 2" of grout injection holes and fill with a non - shrink cementitious grout. 9. Collect data on material usage in each injection point to facilitate best possible material estimate for each type of problem going forward. ESTIMATED MATERIAL USAGE: This project consisting of the 3 test sections of roadway is estimated at a maximum of 7,000 pounds. If project does not require the full 7000 pounds, we will extend the test sections accordingly to provide URETEK and City of Coppell more information regarding the estimated needs for a full project. February 20, 2012 w'uretekusa.�om Mr. George Marshall City of Coppell URETEK USA, Inc. PO Box 1929 URETEK USA, Inc. is pleased to present this proposal of work to solve the Tomball TX 77377 -1929 stabilization issues that you have due to un -corn acted soils around and above utility lines. y p 13900 Humble Rd PROBLEM: Tomball TX 77377 The soils in the water main trench were not compacted properly and /or have loosened. Un- T: 888- 287 -3835 T:281- 351 -780Q compacted soils can cause settlement and /or collapse of the cc roadway above the utility p p y F:281- 351 -0884 trenches. The URETEK Method® Deep Injection® PROPOSED SOLUTION: Stitch -In -Time® URETEK will use the patented URETEK Deep Injection Method and our patented URETEK 486 STAR material to void fill and stabilize the three repair areas as noted on the two attached drawings (and as marked in orange paint on the curb with arrows pointing back at each other). In accordance with the attached specification, URETEK will perform the following operations: 1. Work schedule to complete the entire project is estimated at 4 work days with one truck and crew. 2. Profile roadway of the test sections listed below. 3. Perform Dynamic Cone Penetrometer (DCP) tests, one or two at each location. 4. Inject the following test sections listed below.

ESTIMATED MATERIAL USAGE: This project consisting of the 3 test sections of roadway is estimated at a maximum of 7,000 pounds. If project does not require the full 7000 pounds, we will extend the test sections accordingly to provide URETEK and City of Coppell more information regarding the estimated needs for a full project. PROPOSED COST: URETEK is pleased to offer SMART BUY pricing at $5.50 lb for a purchase order issued through the SMART BUY system. Client will only be invoiced for material used. Saw cutting not included and not required for this project. SCHEDULE: The project should last approximately I week. Tentative start date is 3/12/2012 as traffic should be lighter during the school's spring break. Due to the hydro- insensitive nature of the URETEK 486 STAR material, URETEK can continue to work and inject the material in the rain. We would stop the project if there was lightning or if the rain posed a traffic safety threat to our workers or to the traveling public. NOT INCLUDED: 1. Bond 2. Saw cutting 3. Traffic Control WARRANTY: URETEK will provide a two -year unconditional warranty against movement of more than '/4" of the injected area. In the unlikely event that movement of more than '/4" in the injected areas occurs, URETEK will return to inject the affected area to lift to proper grade at no cost to the owner. MERIT SHOP CONTRACTOR: General contractor recognizes that URETEK is a merit shop contractor, and all services provided by this sub - contractor agreement will be on a merit shop basis. All reference to labor agreement of any kind, or alluded to, in the principle contract or the sub - contract, are set aside, and not part of this sub - contract. INDEMNIFICATION and HOLD HARMLESS: To the fullest extent permitted by law, URETEK will indemnify and hold harmless the Owner, it's consultants, agents, and employees from and against claims, damages, losses and expenses, including, but not limited to attorney's fees, arising out of or resulting from performance of the Work by URETEK, provided that such claim, damage, loss or expense is attributable to bodily injury, sickness, disease or death, or injury to or destruction of tangible property (other than the Work itself) including loss of use resulting there from, but only to the extent caused in whole or in part by negligent acts or omissions of URETEK, it's Subcontractors, or anyone directly or indirectly employed by them. SAFETY: Safety — Our people are our most important asset and safety is our top concern. URETEK has an impressive safety record. URETEK's Workman's Comp discount rate is 0.69 due to our experienced crews and our safety record. URETEK has an extensive safety manual directly pertaining to our polyurethane injection process. URETEK has employed an industrial hygienist company to produce a safety report on our production unit, process, and personnel. The report clearly shows on -site safety procedures in using and handling the process chemicals and equipment. The report is available upon request. Utility Locates will of course be called in by URETEK USA so that all utilities are marked in the locations to be worked. However, since we need to stabilize in, around, and above the trench areas that contain the water pipes, we will need to drill holes within the "safety" zone nonnally considered a "no -dig" area. After we drill through the concrete above the water pipe, we will vibrate our injection tubes down around and above the pipe utilizing a hilti drill. The injection tubes are steel with a steel tip on the end to prevent soils from entering the tube. While this should not pose any threat to the water pipe, no doubt a representative of the utility company will need to be on site during this process. We may need your assistance in arranging this with the water company. We may also need to have a pre - construction meeting with you, the utility company and URETEK to discuss all aspects of the project. INSURANCE: URETEK has insurance in excess of any requirements client may have. URETEK also carries a $20 million umbrella policy.
