Agreement for WCRI 3/34 Intersection Project DEPARTMENT: Public Works PERSON REQUESTING: Don Dunker and Michael Bedell Brief description of the problem/issues DATE: April 1, 2019 The WCR.13/34 Intersection Improvements Project requires dewatering design and construction services to assist County crews with the installation of a precast concrete box culvert. The location for the box culvert is in a wet swampy area with a high groundwater table, which is within one to two feet of the ground surface. The proposed dewatering services are intended to dry out the construction area and draw the groundwater table down to a couple feet below the excavation elevations. Public Works staff believe these services are necessary to complete the box culvert installation in a timely and safe manner, and County crews do not possess the expertise and specialized equipment required. This vendor is well -qualified to perform this specialized work. The attached Agreement and associated exhibits have been reviewed by the vendor and the County Attorney's Office. The proposed not -to -exceed cost of the proposed dewatering design and construction services is $406,020.00. This cost may underrun, depending on the associated soils and groundwater investigation, which will dictate the construction methods to be utilized. There will be a separate Notice to Proceed for the Design Phase and the Construction Phase as described in. Section 3 of the Agreement. What options exist for the Board? (include consequences, impacts, costs, etc. of options): Allow the attached Agreement to be placed on the next available BOCC agenda for signature. Request a work session to discuss. Recommendation: Staff recommends approval of the Agreement as written. If approved by the BOCC this work is scheduled to take place mid -April through mid -July 2019. Sean P.

(Mersino) appreciates the opportunity to present this proposal for RFP # B190063 — Dewatering Design and Construction Services for WCR 13/34 for Weld County, Colorado. We thrive on the challenges presented by each project whether small or large. Selecting and engineering the best solution for your needs is our expertise. Mersino offers full -service dewatering with experienced engineers and project managers who can deal with all the unique variations of each job. BACKGROUND: Weld County, CO has issued an RFP for design and construction services associated with the dewatering of the ground to facilitate construction of a box culvert. The box culvert is located at the intersection of Weld County Roads 13 and 34 approximately 2 miles east of the town of Mead. The Box Culvert is a 16 foot wide, 5 foot tall, by 252 foot long pre -cast concrete structure that will require subgrade cuts of 6 to 8 feet below the existing ground surface, The box culvert will be constructed by Weld County construction crews. Weld County requires the ground be dewatered by a qualified dewatering contractor who will provide a dewatering system design for the proposed structure. DEWATERING DESIGN SERVICE& Mersino proposes dewatering design services that will consist of the following: eQtec/hnc1 investigation — This proposal includes three borings, extending up to 20 feet below grade, to be performed adjacent to the proposed culvert placement, two of which will be outfitted as temporary groundwater observation wells. Prior to mobilization, the proper Weld County and DOT permits to advance the borings from the shoulder of County Road 13 will be obtained, and appropriate traffic control measures will be put in place. Following completion of the drilling, select boring samples will be taken to a laboratory for grain size and hydrometer analysis and/or atterberg limits, whichever applies. The findings will be summarized in a letter report with boring logs that will be stamped by a Colorado Professional Engineer. Utilities impact investigation — This proposal includes Colorado 811 to be notified to have Tier 1 and Tier 2 utilities located with paint marks and stakes within the area of interest. A vacuum excavation will core the street (if required) and pothole the locations of existing utilities. A field engineer will be present to note the type, depth and location of the existing utilities. Information collected will be summarized on an "as -built" utility location plan. These utility locations will be re -marked prior to installation of dewatering system (if necessary). Our proposal is based upon the located utilities being within four feet of the locates. Should this not be the case, it may require additional time and effort to identify the miss -located utility. We will notify you if there are any delays as a result of miss -located utilities. Environmental impact investigation — Water samples will be collected from the observation wells and taken to the laboratory for environmental testing. Our proposal excludes provisions to remediate contaminated groundwater. Required Permits - This proposal includes permitting requirements from the State of Colorado including: • CDPS water discharge permit: Utilizing information collected from the geotechnical investigation and laboratory testing. Water samples will be collected from the observation wells and taken to a laboratory for environmental testing. The acquired permit will identify the location(s) where pumped groundwater can be discharged as well as the required treatment for suspended solids and/or environmental contamination, if detected. • Department of Natural Resources (DNR) Forms GS -51 for Observation Well installation and decommissioning. • DNR Forms GWS 09 for Dewatering Well installation and decommissioning (if applicable). • Mersino will also obtain USACOE maps delineating the location of jurisdictional wetlands to avoid construction activity in these areas. Detailed Design of a Suitable Dewatering System — Once the geotechnical investigation has been performed and results provided, Mersino will assess the soils and conduciveness to dewatering techniques and provide a preliminary design for the proposed dewatering system to the County, describing in detail our dewatering system for review/ approval prior to proceeding to final design. At the final design level, Mersino will provide detailed design plans for all aspects of our dewatering system. These include system lay out, general notes, summary of quantities and permitting requirements. The final plans shall be stamped and signed by a Professional Engineer registered in the State of Colorado. This design will likely include calculations in which drawdown, radius of influence, individual well flow and total estimated discharge flow of the system will be analyzed along with shop drawings and dewatering means and methods. item Unit of Cost Dewatering Design Services $ 57,700.00 1 0 1 6 2 E. C O L D W A T E R R D., DAVISON, M I 4 8 4 2 There is no relevant geotechnical data available for the project at the time of this proposal. The site is located near jurisdictional wetlands with standing water below the roadway embankments on the south side of the intersection. Soil Conservation Service data indicates that surficial deposits may consist of silty, clayey, sandy loam and/or sandy clay loam. The construction aspects of the RFP are dependent upon the installation of a dewatering system to depressurize and allow for dry stable subgrade conditions for construction. However, aggressive dewatering methods may not be effective in silty/clayey fine grained soils be encountered. Instead, standing water may be removed from the trench utilizing sump pumps and/or trash pumps where soft very fine grained saturated soils may be found to be present that may not be suitable to provide a stable subgrade. Should our investigation indicate this type of subgrade, Mersino would provide an alternative design to over excavate and provide a geotecanical solution to improve the subgrade conditions potentially without the use of a well point or submersible pump system. it is feasible that the solution may require a combination of pre -excavation dewatering and geotechnical improvements to accomplish the project objectives. This service is not included in this proposal. Actual conditions encountered will dictate the final dewatering solution. Item Unit of Cost Estimated Alternative Geotechnical Subgrade Stabilization Design $ 36,000.00 CONSTRUCTION SERVICES: Without available soil information Mersino has laid out a number of potential dewatering services which cover the most likely possible solutions from the currently available project information. Once completed the geotechnical survey and report will ultimately determine the remaining scope of the project. For the sake of providing order of magnitude for potential design methods and systems, Mersino has anticipated the following scenarios. We//point D. atering: Should the results of the geotechnical report indicate soils to be conducive to aggressive dewatering techniques, it is anticipated that wellpoint dewatering may be the method of choice based on the excavation size and depth. Manual jetting is Mersino's standard installation method for wellpoint dewatering, however should the noted soils be too dense or contain high blow counts, pre -drilling of the wellpoints may be required. Pricing has been provided for both methods. Mersino will provide a wellpoint dewatering system scenarios as follows: 1.) If significant perched water is discovered in permeable soils atop impermeable (i.e, clay) soils that may be present near the bottom of excavation, wellpoints will need to be installed on both sides of the excavation, if the design practicality does not impede on construction access. This scenario will consist of two systems, each include a single open diesel wellpoint pump, up to 300 linear feet of suction header with wellpoints (600 linear feet total) and 200 linear feet of discharge piping (400 linear feet total) 2E 0 D W D 4 8 4 2 Item MMnW..MMYw.a'u�pR....—Mw/� �MXMYM Unit of Cost d Mobilization/ Jetting 1.

If permeable soils are discovered to the depth of approximately 20 feet below grade, Mersino will provide a single wellpoint system, installed along one side of the proposed excavation. This scenario will consist of a single open diesel wellpoint pump, up to 300 linear feet of suction header with wellpoints and up to 200 linear feet of discharge piping. Item Mobilization/ Jetting Installation/ Removal/ Demobilization Mobilization/ Pre -Drill Installation/ Removal/ Demobilization Rental of (1) Wellpoinf Dewatering System for 60 days Unit of Cost $ 49, 514.00 $ 83,227.00 $ 60, 200.00 , Noted discharge footages is assuming the dewatering system can be discharged downstream/ downgrade of the water way the culvert is being constructed within, within 200 linear feet of the pump placement. These footages, and associated costs, will be subject to change dependent on the CDPS water discharge permit. The above wellpoint pricing scenarios consist of Mersino providing an all inclusive (turn -key) dewatering service including mobilization of equipment and crew, installation and removal of the wellpoint dewatering systems, demobilization of equipment and crew upon project completion, appropriate filter material, equipment for unloading/ loading, water supply for installation and all fuel and fueling operations for 60 days of operation. Open Pumping / urn in- : Should the results of the geotechnical report indicate soils not conducive to aggressive dewatering techniques (i.e. clay soils), it is anticipated that open pumping/ sumping will be the most cost effective approach. In this scenario, if the Weld County Construction Crew do not have such equipment capabilities, Mersino can gladly provide a multitude of pumping options. Mersino would recommend the provision of a standard sump system consisting of three sets of 3" 5HP (480v/3ph) electric submersible pumps, 10' long screened sump cans, 30 feet of hard flex hose to bring the water out of the excavation and with 200 linear feet of layflat discharge hose. Mersino would provide a 25kVA generator capable of powering all three sumping systems. Quantities are recommendations and it is Mersino's assumption that Weld County's construction crews would move and install the sumping equipment for the excavation as construction progress proceeds. This is provided as a rental option that is to be installed/ removed by others. Pricing for the above standard sump system option noted above, including anticipated fuel consumption, is as follows: r O 1 6 Item Delivery of Equipment Unit of Cost $ 3,860.00 Rental of (3) Sum:ping Systems & (1) 25kva Generator for 60 days $ 34,267.00 , L W A T F D V SO ..

If additional dewatering systems should be required and requested by Weld County in excess of that which is quoted above, additional systems can be provided at additional costs and upon written agreement of the parties. Mersino bears no responsibility for drying up any existing water wells in the area (including residential wells), or damage to existing structures due to the dewatering process. Weld County shall have the entire risk of loss of, damage to, or destruction of the equipment from all causes whatsoever during the term of this project and thereafter until Mersino's equipment has been demobilized from the project site. It is the responsibility of Weld County to secure the jobsite and the equipment supplied by Mersino from risk of floods or other natural disasters. Prices are based upon unrestricted operations. Mersino shall not be held liable for any costs or backcharges due to strikes, delays, changed project conditions, differing site conditions, inaccessible job sites, acts of God, inability to obtain permits, force majeure, and/or any other unforeseen conditions (including but not limited to any impervious materials). If conditions arise to install more equipment, a mutually agreed upon price schedule must be negotiated before such additional work commences. If Mersino is delayed in the process of installing or removing the leased equipment, the additional labor and equipment costs incurred shall be compensated for by Weld County. In closing, whatever the soil results may be, Mersino will work diligently with the County to provide a cost effective dewatering solution. Mersino again appreciates the opportunity to provide a proposal on this project and wants to affirm our willingness to enter into the Weld County Standard Contract Agreement as included as part of the RFP, should we be chosen.

Project: Olmstead Lock & Dam LBA Installation Location: Olmstead, Illinois Project Contact: Wade Miller with AECOM Phone Number 270-559-3776 Similar Requirements: This project required unique installation techniques to administer proper dewatering on the project. We were chosen because our bid and technical submission was the only bid that indicated the RFQ was fully understood. Olmstead Dam replaced two of the original locks and dams that were completed in 1929, and it was the last dam in the system to provide a year-round channel for navigation that begins at Pittsburgh, Pennsylvania and ends in Cairo, Illinois. The darn was built in an "in -the -wet" method to minimize impacts to river traffic and the environment. This project is similar in requirements because it too required design considerations for achieve dewatering success. 2.) Project: Ann Arbor Wastewater Treatment Plant (WWTP) Location: Ann Arbor, Michigan Project Contact: Chris Klaff with Walsh Construction Phone Number 313-218-3468 Similar Requirements: Due to artesian pressures of up to 20 feet above ground surface at the project site in conjunction with the proposed excavation depth, Mersino proposed depressurization systems consisting of 24 deep wells to varying depths throughout the site for plant improvements and renovations. This project is similar in requirements because in order to properly design the wells and filter materials, Mersino also provided geotechnical investigation services, from which samples were analyzed and results were used to design the wells prior to installation. 3.) Project: Anhydrite Pond #9 Chlorides Wash Location: Winnie, Texas Project Contact: Bill Bottomley with Fluor Federal Petroleum Operations, LLC Phone Number: 504-734-4304 Similar Requirements: The Big Hill Federal Oil Reserve Station was built on a salt deposit near Winnie, Texas. Contractors used high pressure water to `cavern' out the deposit to create storage capacities for the crude oil stored on site. In the process of doing so, the wash water was brought up to surface and pumped to settling ponds. When the #9 pond was no longer needed, the plant decided to decommission it. Texas law states the chloride deposits in the pond would have to be reduced to an acceptable level before capping the pond. They had two choice; either truck the material to Nebraska (the only place that would accept the material) or to try and `wash' the chloride from the pond settlement. Mersino performed a pilot run on one of the corners of the pond in May 2016 to see if it would meet the acceptable levels of chloride. Upon completion of the test, it was determined that Mersino was successful and met the levels set forth by the state. Once the test was determined a success, Flour granted Mersino the contract extension to complete the entire pond. Mersino installed 700 wellpoints throughout the pond and has now been decommissioned and is awaiting final results of testing for compliance with Texas regulations. This project is similar in requirements because it required Mersino to get creative in designing and executing systems for this special application. 1 0 1 6.'

KUE was retained by the Contractor Underground Infrastructure to conduct a site investigation, perform a hydrogeological evaluation of the site and provide recommendations to facilitate the tunnel installation. Prior to mobilizing KUE evaluated the dewatering system already in place and back -calculated hydraulic conductivity (k) at the site from flow measurements at the discharge line. KUE mobilized, advanced three borings and installed three observation wells at the site. KUE collected samples for grain size analysis and performed rising and falling head tests within the observation wells to estimate (k) and confirm estimates from the discharge line. KUE performed calculations to evaluate the wells size and spacing that would be required to dewater the launch and reception shaft and determined it would take deep wells with 15hp submersible pumps on 6 foot spacing to reach the KILDUFF UNDERGROUND. ENGINEERING,INC QL'AUTCATKONS FFOR DEWATERING SYSTEM DESIGN required drawdown. These findings eventually led the Contractor and Owner to decide to re -design the shaft and tunnel alignment at a shallower grade to avoid additional costs associated with dewatering.

As part of that scope KUE collected samples from the field, performed grain size tests and performed rising and falling head tests within four observation wells installed at the site. The data was utilized to perform seepage estimates into a 100 foot deep shaft that would be founded within alluvial silty sand and cemented sand deposits. Results of the analysis led to the Contractor choosing a water tight secant pile shaft design. Additionally, KUE performed seepage estimates into the tunnel and our analysis resulted in the selection of a slurry microtunnel system to install a 72 -inch diameter tunnel. KILDUFF UNDERGROUND ENGINEER NG,INC Dewateril QUALDaMCATWONS FOR DEINATERING SYSTEM DES] Projects performed with other Firms: GM Twin Tunnels East: Bo nd, CONSTRUCTION, [ daho Springs, CO (2013) While employed by others Mr. Kilduff helped procure a tunnel water collection system that would remove seepage from rain events and nuisance water from construction operations. The systems was designed with over 1000 LF of 12 -inch HDPE header pipe and a collection system that included three 10,000 gallon flocculation tanks and a carbon filtration system before water was discharged into the municipal system. The was designed and procured by the Contractor. Meadowmere Pump Station DESIGN, NYCDEP Queens, NY (2004-2006) While employed by others Mr. Kilduff performed a geotechnical site exploration to characterize the site hydrogeology to evaluate dewatering system designs to facilitate the construction of eight shafts, 4000 LF of open cut trench and a deep pump station. Following the geotechnical exploration Mr. Kilduff estimated the site hydraulic conductivity (k) by utilizing grain size tests and by performing rising and falling head tests in ten separate observation wells. Utilizing k, an estimate of total flow, drawdown, well spacing and radius of influence was evaluated at each shaft and at the pump station. Dewatering designs at each shaft utilizing one deep well pump and required a second back up well for redundancy. The pump station was designed to be dewatered with ten submersible deep well pumps. The open cut trench was dewatered utilizing a well point system. In addition to the dewatering system design calculations were performed by Mr. Kilduff to evaluate the time rate of settlement for an organic clay layer that was present at the site. As a results of the high potential to impact utilities and third party structures it was decided to minimize the section of open trench to 100 feet and utilize the well point system which could be put into place and moved ahead to the next zone rapidly before significant settlement would be induced by the dewatering system. Meadow 4 ere Pump Station CONSTRUCTION, NYCDEP Queens, NY (2007-2008) While employed by others Mr. Kilduff was the project manager with the general contractor who was contracted to construct the pump station and new sewer project. Mr. Kilduff subcontracted Moretrench American Corporation to install and maintain the dewatering system as previously designed by Mr. Kilduff while he was with another firm. During construction Mr. Kilduff reviewed subcontractor submittals and oversaw the installation and maintenance of the dewatering system. As a result of encountering contaminated groundwater Moretrench designed a system that utilized carbon filtration and air stripping to remediate the groundwater before it was discharged through an outfall in the Jamaica bay. South Dam, Birmingham Water Works Board, (1999) Mr. Kilduff was a staff engineer who helped evaluate an option to install a new low level outlet pipe by tunneling through the embankment from the downstream side and into the dewatered reservoir. Mr. Kilduff performed calcualtions to determine well spacing and drawdown to achieve the dewatering operation. Hillview Res tel rvoir Dewatering & Maintenance, Yonkers, NY (1998) With others, Mr. Kilduff performed a subsurface exploration and evaluated the site hydrogeology for drawdown of the reservoir. Later, Mr. Kilduff was the on -site field engineer who oversaw the dewatering system and monitored the a dividing wall for movement. The project required the drawdown and maintenance of the reservoir facility (cleaning and replacement of concrete slopes and floor). The reservoir water levels were regulated with a 30 -foot high concrete dividing wall that for the requirements of the project needed to essentially become a dam to resist the full thirty feet of head on one side while the other side was drawdown to perform the maintenance. The dewatering system served two purposes: (1) to drawdown groundwater to access the reservoir floor and (2) to resist the hydrostatic pressure on the dividing wall when at full drawdown. The engineering team chose a jet educator system to achieve the dewatering goals. Mr. Kilduff performed daily inspections on the system and helped maintain the system at optimal capacity.
