ABO ABOUT ME • Bachelors degree in Geomatics (Surveying & Mapping) • Majority of my construction career has been spent with Trimble • 13 ½ years in support & training and product development • 3 ½ years at BuildingPoint • Involved in the development of LM80 Layout Manager, RTS series instruments, Trimble Field Link, RPT600 and many other projects • Spent 1 ½ years working as a Topcon distributor • Named as an inventor on multiple US patents related to construction positioning • Currently work in business development for TriBuild, Inc. • Married for 19 years, two sons, volunteer with the Boy Scouts of America
LE LEAR ARNING OBJE BJECT CTIVE VES 1. Understand how a robotic total station is used for laying out on a construction site 2. Understand the different data file formats used to prepare data for layout 3. Understand some of the layout data preparation software tools available 4. Understand the basic workflow for preparing data for layout on the jobsite

EV EVOL OLUTION TION OF OF CONS ONSTRU TRUCTION TION LAYOU YOUT • Legacy tools & methods still dominate but are not sufficient for many current projects • While adoption of digital layout solutions started around 2000, half the industry still hasn’t invested in the technology • An aging workforce is hesitate (even obstinate) to adopting new tools & technology • Layout is one of the few places on a job where a contractor can increase their margin
CO COMMON LAY LAYOUT AP APPLI LICAT CATIONS • Foundations / Footers • Anchor bolts • Walls • Hangers • Sleeves • Lights (poles, hanging) • Stub-ups • Electrical boxes • Runs (pipe, conduit, duct, etc.) • Equipment locations
CO CONST STRUCT CTION LAY LAYOUT WITH A A TOTAL AL ST STAT ATION • A total station is a surveying instrument which measures angles & distance (not satellites) to determine positions • Each measurement from a total station is radial and independent from the others – errors don’t compound • Robotic total stations are motorized and only require 1 person to operate • Laying out with a total station offers increased speed and accuracy over traditional tools • Investing in a robotic total station can pay for itself in only a couple of months • Layout is performed directly from a digital file and is not likely affected by missing dimensions on a drawing or human errors in calculating lengths

LAY LAYOUT DAT DATA A PREPAR ARAT ATION • Preparing for field layout consists of creating points at critical locations from a design (2D or 3D) • Points serve as a task list of the work that needs to be performed • Organizing and managing points by assigning points names / numbers, descriptions and groupings (layers) aids in field operations • Creating layout points can be done in a variety of applications • Design applications with add-on tools • Standalone office software • Layout field software • The majority of points should be created before going to the field
LAY LAYOUT DAT DATA A PREPAR ARAT ATION (Co (Cont.) • There are a number of software applications available to support for a variety of file types, workflows and contractor needs • As discussed, there are only a design file types that are used for preparing layout data – PDF, DWG/DXF, RVT, NWD • If a standalone application is used, they rely on libraries, APIs, SDKs (or other means) to work with the design file • Any time a conversion occurs, there is a potential risk for loss of data or other errors

VE VECT CTOR VS. VS. RAST ASTER PDF • Vector PDFs are comprised of geometries and are generated by “exporting” from a design application • Raster PDFs are “pictures” of drawings and are generated by scanning a document or through a software conversion • Raster PDFs are not usable for layout because points cannot be “snapped” to locations and drawing scales are not accurate (or consistent) • Raster PDFs are the equivalent of other image files (TIFF, JPG, GIF) • Stamped drawings are most likely raster format • Some drawings are intentionally converted to raster format to prevent their use for more than visual reference

DA DATA LO LOSS SS FROM IMPORT / CO CONVERSI SION • Software applications use libraries, APIs or SDKs to tell it how to represent the non-native files • Libraries may be outdated or possibly intentionally missing capabilities (to protect intellectual property) • Incomplete libraries could result in inaccurate data (scale or location) • Imported or converted files should be carefully reviewed to ensure there are no errors which could lead to problems on the jobsite

CON CONCLUSION CLUSION
KE KEY TAKE AKE-AW AWAY AYS • Traditional layout tools are often insufficient for modern projects • Laying out with a total station provides an opportunity to improve profitability • Prepare data for layout inside design applications whenever possible – avoid unnecessary conversions • Total station manufacturers are not the only providers of layout data prep software • Not all file sources and formats are created equal
TH THING NGS TO C TO CONS ONSIDER ER • Is your current process the right process? • Are you converting files unnecessarily? • What are your data sources? Are you sure they are your only / best data sources? • What functionality do you need? • Who / how many people will be preparing data? • Costs
