Presenters Rich Steffens is the Engineering Manager at Douglas Steel and has been with the company since 1992. Rich has been using the SDS/2 software since 1995 and has been a member of the SDS/2 Advisory Board since 2012. James Schwartz, who serves as Design Data's Software Advocate, has been with the software company since 2000. In his present capacity, he is responsible for research and development; customer assistance, focusing on integration between engineers, fabricators, BIM coordinators, detailers and erectors; consulting on projects; developing training programs; and assisting programming staff. James has performed seminars and training sessions around the world. Prior to joining Design Data, James worked in the construction industry as a structural steel detailer on projects ranging from small commercial to large industrial, and serving small and large fabricators both in USA and Canada. He was certified as a Class 1 senior detailer by the NISD in 1998.

Connecting SDS/2 with the Field Case Study: The Boldt Company

Boldt History • Professional Construction Service Firm • Established in 1889 by Martin Boldt • Family-led and employee-owned – https: //www. theboldtcompany. com/ • Purchased SDS/2 Erector 2015 • Key industries • • • Healthcare Power & Energy Industrial Automotive Education • • Commercial Science & Technology Religious Public Sector

Merrill Steel • AISC Certified Premier Fabrication and Engineering company. • Capacity of 60, 000 US tons per year. • High quality fabrication model provided by Merrill Steel. • Extremely cooperative! – http: //www. merrillsteel. com/

Connecting SDS/2 with the Field • The fabricator’s model contains the most accurate and up to date information • Ability to take advantage of the fabricator’s 3 D model created by Design Data’s SDS/2 Detailing software • 3 D model is source of all data needed for fabrication: – Weights, center of mass – Quantities – Bolts – Assembles fabricated from model – Status Info (i. e. shipped, erected, etc. ) – Fabrication and erection drawings • 3 D model has reporting and status tracking tools which permit; – A visual aid to help everyone understand the plan – Helps keep project on schedule

About the Consumer Energy- West Olive, MI § Steel Erection Sequence Coordinated with 90000 lbs of Duct section Installation § Erector Station provided 3 D model data for Steel Erection Sequence Breakdown

CONNECTING SDS/2 WITH THE FIELD • Problem to solve – Outage could only be for 24 hours. – 100 workers needed to be in and out. – Had to be exact and run like clockwork.

SDS/2 – Consumers Energy Project § Due to time restrictions, Erector Station was used to determine assemblies that were staged off site. § SDS/2 Frame Sequence Detail & Weight

SDS/2 – Consumers Energy Project § Create “pre-assembly” erection lists to assist with pulling steel from laydown area § Create erector sequencing work packages § Reporting and status tracking § RFI’s § Daily progress reports » Productivity tracking » Future erection planning

SDS/2 – Consumers Energy Project § SDS/2 Erector generates the following items for the work packages: – Excel list of members to be erected with piece marks and weights – Bolt list – 3 D PDF for field use (tablet)

SDS/2 – Leveraging the 3 D Model § 3 D model has reporting and status tracking tools which permit; – A visual aid to help everyone understand the plan – Helps keep project on schedule

Connecting SDS/2 with the Field • Demonstration of creating “Work Package” used by Boldt • Demonstration of Cranes • Demonstration of Import

How SDS/2 Erector has Impacted Boldt’s Process • We are able to use it to nail down our steel erection sequence allowing us to maximize our early start of setting duct work which will open up work for our Boilermakers. • We are able to create pre-assembly and erection set lists which are given to the FM to assist in pulling steel from the laydown. • We further tied all of our erection sequences directly to our P 6 schedule. • The visual aid of what each activity in the schedule helped all office personal and the owner understand the plan.

Benefits of Access to the Fabricator’s Model • It appears to be unlimited benefits which we have only begun to see. • We are able provide slide shows of the steel erection by sequence. • Anytime there is a question about a connection we are able to answer our own questions through the model or write RFIs which are easier for the engineer to understand by using model shots. • We are able to get accurate piece counts, weights, and bolt counts which all assist in accurately tracking production and scheduling.

Improving Lines of Communication • The model eliminates all communication breakdown about the "plan. " Everyone is able to sit in one room and fly through the model looking at possible issues and what sections could potentially be preassembled. • By having accurate part lists we eliminate the FM missing pieces when loading trailers in the laydown. We also are able to ensure that all pieces in a sequence are installed eliminating the need to go back at a later time.

Connecting SDS/2 with the Field Top Tools for Creating Work Packages • The most useful tools for our process have been: – RFI Creator (3 D PDF) – Point to Point Reports – Custom Reports – Ability to see how fabricators sequences interact with each other which you cannot always see from the erection sheets.

Connecting SDS/2 with the Field According to Boldt… • What Erectors and GCs should know – Get training early on. – Sit down with the fabricator early on and review sequencing and how the model is set up. – Take advantage of the possibility of bar coding. – Use the point -to-point lists as a sign off for every connection. This will eliminate extensive punch list and rework.

Connecting SDS/2 with the Field Final Points

Connecting SDS/2 with the Field • • • Visual - to be able to see the steel and it's connectivity quickly without sifting through drawings, yet still having direct access to the drawings. Quick determination of what the fabricator assembled, and what is field assembled. Locating items - ability to find the locations of items such as member locations, or even if they are fabricated or on site. Reporting of data - for example; bolt summaries, bolt point to point lists, Weekly erected tonnage, etc The data is contained in the model, you just need to extract it. "Work packages“ – – – • Setting up the erection sequences Creating and storing assembled lifts, and their weights including the center of gravity. Creating bolt and tonnage reports Tracking completed work and updating to fabrication model. Porting the data to the site on mobile devices. Cranes - determining the feasibility of selected cranes by determining effective placements and generating reports and placement plans as per AISC erection certification.
