Methodology
MERSINO chose to install gravity deep wells because of the depths and site soil conditions. The soils were a mix of silts, clays, gravel, sands and caliche rock. With the cemented characteristics of the caliche, MERSINO employed the Casagrande drill rigs to produce down-hole pressure in order to break up and drill through those layers. With the concrete machines being used, the contractor had their field surveyors place each well at coordinate-specific locations as to not hinder the pouring operation.
Multiple people were involved from start to finish, even if they never made it to the site. George Olsker opened the door by giving us the opportunity to quote the job and maintained a relationship with customer personnel. Joe Cherluck completed the proposal after many hours of researching the soils, lining up vendors and applying for the permits. Stacy Simms coordinated travel, rooms, renting and furnishing the apartment, on top of all the other administrative responsibilities. Kevin Quaderer organized getting materials to the site, and Ryan Oliver, Matt Tunnell and Rickey Montgomery built the project in the field. Due to the great working relationship between MERSINO and Las Vegas Paving, the project was completed months ahead of schedule.
Challenges
The diverse soil conditions, including layers of silts, clays and caliche, made for difficult dewatering conditions. Additionally, three straight months of triple digit temperatures, beyond the normal 90’s, were endured with little to no shaded areas. In the rare instances when it rained, all our equipment would need to be removed out of the wash channel because the normally dry work area would almost flood in a short period of time, potentially damaging our equipment.
