Welcome to Technology&more: More Than a Decade of Worldwide Projects Dear Readers, It’s hard to imagine, but this issue of Technology&more begins our eleventh year of bringing you articles about our customers' innovative surveying projects around the world. From our first issue in 2002 to today, Technology&more seeks to showcase projects that demonstrate the enhanced efficiencies and expanded capabilities that can be gained through the use of Trimble® technology solutions. As always, we hope that the articles will provide useful ideas and information that will benefit you and your business today—and tomorrow. In this issue, you can learn how 3D scanning created a complete record of the before—and after—configuration of the University of California football stadium during a major renovation project; GNSS and GeoSpatial solutions aided the early recovery efforts in the city of Christchurch, NZ, following a disastrous series of earthquakes; integrating optical and GPS/GNSS surveying gear enables one person to measure and record the often rapid changes in the coastline of South Wales in the UK; all aspects of construction for a major Metrorail extension project near Washington, DC, were controlled through a Trimble Connected Site solution; “pre-surveying” helps speeds track laying in central Germany; and 3D scanning makes it possible to accurately record 40,000-year-old cave artwork in Spain. Chris Gibson: Vice President, Survey Division Published by: Trimble Engineering & Construction 10355 Westmoor Drive Westminster, Colorado 80021 Phone: 720-587-6100 Fax: 720-887-6101 Email: T&M_info@trimble.com www.trimble.com In all of these projects, Trimble solutions, whether incorporating GNSS, Optical, Spatial Imaging, GeoSpatial, GIS or VRS technologies, helped users do their jobs faster and more efficiently—and in some cases, do work that literally couldn’t have been done a few years ago. You’ll also learn how progressive surveying professionals are utilizing specialized application software tools for Trimble surveying systems. The Trimble Access Software Development Kit (SDK) enables software developers to meet specific localized customer needs by developing application-specific software solutions. Trimble Access SDK offers surveying professionals a variety of customizable opportunities, allowing them to perform projects faster, more easily and more productively. If you’d like to share information with Technology&more readers about your own innovative project, we’d like to hear about it: just email Survey_Stories@trimble.com. We’ll even write the article for you. Be sure to mark your calendar for the Trimble Dimensions International User Conference, which will be held November 5–7, 2012, at the Mirage Hotel in Las Vegas, Nevada, U.S.A. Nearly 3,000 surveying and construction professionals attended Dimensions 2010. We hope you’ll be able to attend this year: Dimensions 2012 promises to be another powerful experience, providing extensive educational options, unmatched networking opportunities—and a whole lot of fun. And now, enjoy this issue of Technology&more.

Surveying Wind Farms The rugged terrain of the Appalachian Mountains in Pennsylvania and West Virginia can present challenges to travel and commerce. But the high ridges contain an important opportunity for new projects and revenue: they are ideal locations for wind power. According to the U.S. National Renewable Energy Laboratory, wind in southwestern Pennsylvania can provide more than six percent of the state’s existing electricity needs. And the region generates more than electricity—in 2010, observers reported that Pennsylvania’s wind power industry supported more than 3,000 jobs in manufacturing, construction and operation of the state’s wind farms. From its offices in Pennsylvania and Maryland, CME Engineering LP provides services for wind farm development in southwestern Pennsylvania and West Virginia. CME Project Director Dan Llewellyn said that wind farms call for a range of surveying skills. A major portion of each project is cadastral work to create maps and descriptions for the easements and rights of way that host the turbines, access roads and power lines. Additional work includes construction surveys for road improvements to handle the long trailers hauling turbine blades and towers to the ridge tops. Post-construction surveys include as-built locations of transmission towers and other facilities. The difficult terrain demands a variety of surveying techniques and tools. CME Engineering Technician Asa Maust uses Trimble R8 GNSS with a Trimble TSC3® Controller running Trimble Access Software for both static and RTK surveys. Whenever possible, CME utilizes the KeyNetGPS Real-Time Network (RTN), based on Trimble VRS technology, for its RTK work. “Because of limited cell phone service in many areas, we often use the Trimble HPB450 radio modem for RTK,” Maust explained. “We use repeaters to carry the RTK signals into the deep, narrow valleys.” In areas where total stations are needed, CME technicians set control with GNSS and use a Nikon DTM-332 Total Station to run traverses between the GNSS control points. Roughly 60 percent of control is set using static methods, with the remainder placed by RTK. Most work is done with a precision of 3 mm (0.01 ft). While the required precision varies, Maust said that wind projects have short construction cycles that require flexibility and quick response. He cited West Virginia’s Pinnacle Wind Farm, which has 23 turbines and will supply power for 14,000 households. Construction began in spring 2011 and the farm was in full production by the end of 2011. Two CME crews used static GNSS to establish more than 100 control points for construction, aerial photography and cadastral surveys. CME also provided surveying for roads, turbine foundations and transmission lines. Work on the wind projects is not letting up. Like many states, Pennsylvania has voter-approved requirements for increased use of wind and other alternative energy sources. It’s an important opportunity, and surveyors with flexible tools and techniques will be well positioned to meet the demand. -1- Technology&more; 2012-1
