MOUNTAIN VIEW HOSPITAL UTILITIES
Owner:  HCA
Engineer:  ICT
Location:  Las Vegas, NV
Contract:  $1,153,664.00
General Contractor:  Layton Construction
Completion Date:  November 2014
This was a design assist project to replace the existing underground utilities for a future expansion.  This was also a fast track project as the existing lines were leaking but could not be taken out of service until the new lines were run.  We worked on the layout and design with the engineer as well as the city.  We went through 5 design packages before the city's approval due to the main power station on site next to the central plant.  The hospital could not be shut down for any tie-ins so almost all of them were done live as to not hinder hospital activities.  We also replaced some of the main 16" header in the central plant and consolidated the lines at the building into the new 16" lines.

LDS FAMILY HISTORY LIBRARY HUMIDIFICATION PROJECT
Owner:  The Church of Jesus Christ of Latter-day Saints
Architect:  Van Boerum & Frank Associates
Engineer:  Van Boerum & Frank Associates
Location:  Salt Lake City, UT
Contract:  $498,043.00
General Contractor:  Layton Construction
Completion Date:  November 2014
Installation of a new clean steam humidification system which included demolition of existing steel piping and humidifiers, new stainless steel piping, (22) stainless steel duct mounted humidifiers, clean steam generator, and complete control upgrade.  Due to the space restraints and the short time frame to complete the project we utilized our fab shop to prefabricate as much of the piping as possible.  This required close coordination between our on-site superintendent and fab shop foreman.  The project was completed successfully, on time, and to the owner's satisfaction with the new system.

UNIVERSITY OF UTAH HIGH TEMP WATER LINE
Owner:  DFCM
Engineer:  Colvin Engineering
Location:  Salt Lake City, UT
Contract:  $4,010,281.00
General Contractor:  Layton Construction
Completion Date:  November 2013
This project of converting numerous buildings on the University of Utah's campus from using an outdated campus steam system to an efficient high temperature hot water system as a primary heat source.  We furnished and installed over 6,000 feet of direct bury HTHW piping using Thermacor DuoTherm 505 process piping.  We also converted the high temperature water to steam and heating water using U-stamped vessels at seven locations spread across the university campus.  The required complete renovation of many existing mechanical rooms.  This project was an especially difficult one as it required close coordination involving so many buildings on campus to keep them under normal operation and occupied during the entire process.  Requiring over 500 pipe welds to pass x-ray testing for high temperature and pressure systems, J&S successfully completed the project in under twelve months.  We were able to sequence work to keep buildings operating normally during peak heating loads, incorporate numerous unforeseen conditions, and provide a functional heating system for the owner to rely on for many years to come.

SORENSON MOLECULAR BIOTECHNOLOGY INFRASTRUCTURE - USTAR

This project consisted of installing utility piping in a tunnel to be distributed to several campus buildings with some direct bury reroutes.  We installed over 3,300 feet of 10" high temperature lines, 600 feet of 24" chilled piping, 2,100 feet of 12" and 10" grooved ductile iron waterline and 400 feet of 6" and 4" natural gas line.  This project was LEED and required X-ray, detailed weld maps, commissioning, and a confined space program.  The project was successfully completed on time within the original 6 month duration.

CHURCH HISTORY LIBRARY - UTILITIES
Owner:  The Church of Jesus Christ of Latter-day Saints
Architect:  MHTN Architects
Engineer:  RMH Group
Location:  Salt Lake City, UT
General Contractor:  Jacobson / Swinerton a Joint Venture
Completion Date:  March 2009
The heating, cooling, and humidification for the Church History Library is generated from a campus utility center nearly a half a mile away.  We have installed the steam/condensation and chilled water systems that serve this building through the underground parking structure of the LDS Conference Center as well as in a direct bury application padding through numerous concrete vaults in the process.  All piping was fully welded, tested and weld mapped.  A percentage of the piping was tested through an ultrasonic process and no imperfections were found.  The direct bury piping was installed using Thermacore process pipe in which the steam piping consists of a welded carrier pipe, insulation, a fully welded conduit system, an additional insulation barrier, and an HDPE jacketing that is sealed water tight at every joint.  There is also a leak detection system installed.
 

 

TEMPLE SQUARE UTILITY TUNNEL RECONSTRUCTION

Location:  Salt Lake City, UT
Contract:  $4,044,172.00
General Contractor:  Jacobsen Construction
Completion Date:  April 2005
This project consisted of running new high pressure steam and condensate, chilled water and waterlines in a new utility and pedestrian tunnel through Temple Square.  This was accomplished with minimal disruption above ground and had to be completed in multiple phases to keep certain buildings online.  Working in the heart of Temple Square around priceless structures, reverent atmospheres, and large amounts of daily pedestrians required proper planning, foresight and open communication with the owner, general contractor, and numerous subcontractors.


 

U.S. ROBOTICS / MEGAHERTZ EXPANSION
Owner:  U.S. Robotics
Engineer:  WMA Consulting Engineers
Location:  Salt Lake City, UT
Contract:  $4,378,349.00
General Contractor:  Bodell Construction 
This project was a new manufacturing and office facility for the Megahertz division to produce laptop computer modems.  The project was a fast track project with phasing required to build a temporary structure within the new facility to allow the owner to operate two manufacturing lines during construction of the new facility.  It was critical in the manufacturing area to have constant control of the temperature and humidity because the work needed to be kept at near clean room standards.  Along with the plumbing and HVAC systems, the facility included the following process piping systems; vacuum, deionized water, and compressed air.  The facility also had a complete food service area.  The project was completed in an 11 month time frame.
