The Case for Your Own Layout Hardware

 

If you’re a regular reader of the Trimble Buildings newsletter, you’ll recall the series of case studies we did in preparation for the AGC BIMForum in Denver this past October.  We examined the prefab efforts on our own technology campus in Westminster, CO, and developed four different case studies: the concrete, the steel, the exterior framing, and the interior framing.  While we used twenty-nine different Trimble technologies on our own building, the Robotic Total Station and Trimble Field Link software played a very key role: from layout to quality control and assurance.

 

On this episode of Fridays with Trimble, we’ll take a look at the original field solutions that made Trimble a verb on the jobsite.  “Let’s Trimble it” and see the advantages to having your own gear for your projects.  In this webinar, we’ll run through the use cases to have your own layout gear, as well as many of the ROI anecdotes from projects around the world.

First and foremost, we’ll examine the Robotic Total Station as the vehicle to connect the preconstruction efforts to the jobsite.  We’ll quickly discuss how PEs, Supers, and Crew Chiefs can mark critical layout points in various Trimble software packages like Tekla, SketchUp, Vico Office, and Point Creator and shoot those points on the site.  This would be all the critical points per location for sleeves and openings before concrete is poured, deck elevations before pipes are installed, organic curved walls before the framing starts, hangers and bracings for seismic requirements, pipe runs, slab edges, anchor bolts, embeds, etc.

 

We’ll also see how the Robotic Total Station is utilized for:

 

Logistics: locate property corners or boundaries, jobsite fencing, stormwater management, temporary construction trailers and storage unites, lay down areas, stock pile locations for topsoil and earthworks, and mock up locations

 

Site Work: locate building pads and excavation lines, subsurfaces for parking lots, over-excavation requirements, curb and gutter locations, sidewalks, landscaping, light poles and bollards, loading dock areas, retention ponds, storage tanks, and final grades

 

Utilities: locate as-built temporary electrical, gas, plumbing, and low-voltage lines for the construction trailers and building, layout and as-built site electrical and irrigation lines, layout and as-built sanitary sewer systems, storm sewer systems, and water systems

 

Concrete and CMU: locate piers with offsets, corners and elevations of foundations and pier caps, door block outs and brick ledges, anchor bolts and embeds to within 1/16”, structural cores with openings and rebar clearances, and post-tensioning cable locations

 

Steel: layout benchmarks and grid intersections, offsets at each column or grid intersection and on each floor to allow for quick installation of steel and permanent stairs, layout and check edge angles and openings, check pre- and post-pour camber for steel beams, layout and check steel columns/beams/bracings for accuracy, safety rail stantions at leading edges pre-pour

 

Exterior Shell: locate exterior framing and openings, pre-cast panels and inserts, window openings, glazing systems including anchors, embeds, and edge angles

 

Interiors: floor flatness, layout actual track line in lieu of finished drywall, doors, windows, openings, caseworks, fire extinguisher cabinets, ceilings, soffits, skylights

 

MEP: layout hangers, duct strap, sleeves, anchors, block outs and penetrations before or after concrete pours to install hundreds or even thousands of items in a day, critical wall openings and penetrations for framing, prefabrication items within the shop, electrical fixtures, conduit and cable trays, mechanical runs, valves and piping runs

 

Quality Control: daily layout summaries, deviation reporting, field reports with photos of issues and progress, provide descriptions and exact coordinates of any issues, as-builts of everything in the models for an accurate model to hand over to the Owner, concrete and steel pre-, post-, and during pours, check embeds and anchor bolts prior to steel fabrication to eliminate costly site repairs, check MEP items pre-pour to ensure everything is within the wall cavities or chase areas

 

No one knows your project, your layout needs, or the correct items to watch for quality control better than your team.  You can see the advantage of having your own equipment here.  You select the points within the model or 2D drawings you would like to layout in the field, shoot the points and then your crews or subs are ready to install.  You’re not beholden to another team’s schedule to get the job done.

 

Of course, the reverse is true for the quality assurance check.  After the work has been completed, you can capture the actuals from the site and compare these points to the originals to check discrepancies.  Whether you’re working with Tekla or models in Vico Office Layout Manager, just import the points back and the project team can verify the quality of the construction and check acceptable tolerances using the building model or 2D drawings. When as-built conditions are combined and overlaid with the model, you can make sure that all structures are built according to the plan.  We can see X, Y, and Z as-built coordinates compared to the as-designed coordinates, along with distance, out of tolerance, and percent calculations.  Even more importantly, you can hand over an accurate as-built plan or model of the project to the Owner or to your own project team for future work.

 

Working on our own building project in Westminster, we saw:

• Site excavation was completed four weeks faster than projected, reducing the
  scheduled time by more than 30%.

• Achieved 100% accuracy of embed placement and 50% reduction in structural
  requests for information (RFIs).

• Structural Steel was installed twice as fast as originally anticipated.

• Final steel column placement was within .25-in. tolerance.

• A 30% reduction in mechanical, engineering and plumbing-related RFIs;
  completed MEP layout and hanger install was achieved four weeks faster than
  projected.

• Field layout for MEP installations was reduced from three weeks to seven days.

 

So join us on the next Fridays with Trimble to see how you can apply this technology on your next project.  If you’d like to get a jump start, be sure to check out our ROI calculator.

You and your team won’t want to miss this webinar.  Together we’ll take a close look at:

• Determining when there is a need for layout hardware on the jobsite;

• Developing deliverables that you Owners appreciate and rely upon;

• Creating a core competency on your team around this technology;

• Applying layout on BIM and non-BIM projects.
