ACCOUNTING FOR REALITY & ADVANCING THE SCHEDULE
ADVANCED MODELING, DRAFTING & COORDINATION
By advancing drafting and coordination time to the beginning of the project schedule, before the sub-contractors are hired, granted Trane complete control of the design, engineering and coordination process and they ultimately controlled the outcome of the project. Early production of highly detailed coordinated construction drawings and bill of materials reporting makes real Cost Benefit Analysis and Decision Making possible and not an automatic additional cost. Completing a fully coordinated construction drawing BID set before the trades were hired shortened this construction schedule. On larger projects, contractors include mobilization time then drafting begins and subsequently coordination begins. Our production of a coordinated construction drawing set allowed sub-contractors to get right to work.
THE CHALLENGE: IDENTIFIED SPACE SHORTAGE: SHORT 300+ SQ/FT
When our team aligned the composite point cloud to the existing background drawings in AutoCAD MEP Fabrication, it was immediately discovered that the backgrounds provided did not accurately represent the existing conditions. We observed and verified that the provided backgrounds were more than 300’ feet larger than the actual existing conditions which meant 300’ less space to fit all of the proposed mechanical equipment in an already congested mechanical space. It was apparent that the intended number of ice tanks and equipment were not going to fit per the design. This circumstance threatened the proposed capacity, financial viability, and schedule of the envisioned systems and had an immediate impact on the design and layout of the system. Having early awareness of the severe space limitations made it possible for us to explore every opportunity to re-arrange or reconfigure piping, pumps, chemical treatment equipment and tank placement to make all fit in the lesser space available while maintaining clearances and performance and also minimize the impact on the existing systems to remain.
$100,000 IN SAVINGS BEFORE CONSTRUCTION BEGAN
This Thermal Storage Ice Plant's intended location was in an extremely congested now smaller than previously believed mechanical room. Engineering included the removal of some outdated existing equipment housekeeping pads to make way for ice tanks, pumps and chillers. Elite reconfigured and value engineered the layout of the proposed pumps, chemical treatment skids and tank placement making it possible to reuse and expand existing equipment pads. Over $100,000 in cost savings were realized by identifying that the existing housekeeping pads could be reused and altered instead of having to be demolished and reconfigured in different positions.
FEASIBILITY ANALYSIS: IDENTIFYING COSTLY UNFORESEEN CONFLICTS
We laser scan the proposed equipment rigging paths for each project. Often this data set is never utilized, however the extra time and effort proved to be be of much value at ll Madison as it was utilized to discover, measure and visually communicate that the equipment was not going to make it into the mechanical room without significant demolition to portions of the existing buildings back of house areas. We produced accurate equipment models to test fit their movement through the available rigging paths. The team was able to identify exactly where each piece of unique equipment would not fit measurably in 3D. Feasibility Analysis of the intended logistics plan prior to construction start revealed costly unforeseen conflicts that could have dramatically delayed the entire project.
ADVANCED BILL OF MATERIALS REPORTING
EliteCAD Designs utilized precision measurement, documentation and building information modeling (BIM) to eliminate unforeseen changes, conflicts, surprise schedule creep, and dramatically reduced construction costs. Our process mitigated project risk - by completing a fully coordinated construction drawing BID set before sub-contractors are hired shortens the construction schedule. The earlier design and engineering account for reality, the more greatly the risk is reduced.
