Construction Process • Zoning Issues • Governmental requirements for permits, etc. • Planning & Design • Project Bidding / Tender / Take-off • Material, Labor, and Equipment Estimates • Pricing and Submittal • Project Award • Project Start • Develop digital model of project for control, layout and 3D
Construction Process • Establish Local Control (Cadastral) • Tie site to “legal” control. Preliminary building envelope, setbacks, Right of Ways, establish control points for the site. • Clearing & Grubbing Limits • Establish Area of Disturbance. Segregate environmentally sensitive areas. Identify what vegetation is to be removed. • Verify Existing Topo • Measure existing surface. Compare to original bid plan. Does it match? Are there grounds for additional claims? Volume Difference.
Construction Process • Strip Topsoil • How much is there? How much do we need to put back? What is the actual amount? Monetary, efficiency and space issues. Volumes. • Bulk Earthwork • Cut/Fill Grid. Mass Haul Diagrams. Progress Reporting. Ongoing Volume Differences, Slope Staking, Cut/Fill Staking. • Sub Strata • Unsuitable Soils, Water, Rock. Model and quantities for payment. Volumes and Modeling.
Construction Process • Underground Infrastructure • Storm Drains, Water, Sewers, Natural Gas, Power, Communications, Irrigation. Position, Depth, and Slope Sub Strata and Select Material Volumes. Position & Elevation. • Subgrade and Structural Materials • Subgrade elevations. Structural & Select Material elevations. Grade checking and Material Yields. • Critical Layout Control • Building Corners, Roadway tie-ins, Easements, Right of Ways. All control with “significant legal bearing.” High Accuracy Elevation & Position
Construction Process • Foundation and Structural Surface Control • Footings, Foundations, Concrete Floors, Supporting Structures, Car Parks, Access Roads, Curb & Gutter, Hard Surface Canals, etc. Elevation, Position, Slopes, Offsets, and Material Yields • Superstructure (Building Proper) • Structural Layout - Columns, Anchor bolts, Elevator shafts • Interior Layout - All functional layout. (Walls, utility chases, etc.) • Hard Surface Placement • Roadway & Car Park paving. Hard surface placement. Elevation, Position, and As-built
Construction Process • Topsoil Respread and Landscaping • Finish all unpaved areas for aesthetics and proper drainage. Elevation and Position. • As-Built and Close-out • Measure all finished surfaces and create model. Compare against design for payment and future GIS issues. Surface measurement and modeling.
The Construction Process Using Trimble Grade Control Systems Presenters Name
How do you use TrimbleMachine Control Systems in the Construction Process? A simple scenario to illustrate
1. Strip the topsoil • Guides the operator to the edge of strip • No stakes required Cost reduction • Reduces over strip Cost reduction • Not restricted to scrapers, use any machine • e.g. Dozer/Grader/Excavator/Scraper
2. Excavate unsuitable material • Guides the operator to the extents of excavation • No stakes required Cost reduction • Reduces over excavation Cost reduction • Not restricted to scrapers, use any machine • e.g. Dozer/Excavator/Scraper
3. Compact, validate in-situ material • Measure density using intelligent compaction • Look for soft spots Better to sort it out now than fix later • Record the surface • For volume calculations • Ensure that you get paid
4. Place a layer of imported material • System controls grade – guides the operator • Correct layer thickness Meets spec for compaction • As a result you get a smooth surface • Trucks travel faster Increase productivity • Water runs off if it rains Less downtime
5. Compact layer of imported material • Record the number of passes & measure density using intelligent compaction • Documentation Verify that you meet specifications • Look for soft spots Better to sort out now, than fix later • Record the surface • Calculate the volume Progress payments
6. Place the next layer of imported material • System controls grade – guides the operator • Reduces number of passes to grade, increases productivity • Ensures the correct layer thickness • Meets spec for compaction • Higher quality final product! • To grade with less time & effort
7. Compact the layer of imported material • Record the number of passes & measure density using intelligent compaction • Documentation Verify that you meet specifications • Record the final surface • Documentation that you have meet grade requirements • Calculate the volume Progress payment for imported material
Summary • Integrated solutions for all machines • Reduces costs • Increases productivity • Reduces re-work • Provides QA/QC • Process Improvement • Provides value in all phases of the project • Stripping topsoil • Excavating unsuitable • Grading imported material • Compacting imported material
