Work Request Data System Using 3D Models for Accurate Bidding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional job bidding systems are inefficient and prone to inaccuracies due to the need for physical site visits by contractors to gather data, leading to potential over or undercosting and increased time and effort without guaranteed profitability.
Innovation Solution
A work request data system that uses aerial imagery and a three-dimensional model engine to extract measurements from structures, eliminating the need for physical site visits by enabling users to input locations and derive necessary data through a graphical user interface, which is then used to generate bids based on exact dimensions and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contractors perform physical site visits to gather data, then measurement accuracy can be achieved, but time consumption and operational costs increase
Solution Approach 1:
The system performs preliminary data collection by capturing aerial imagery and generating three-dimensional models of properties before the bidding process begins. This pre-prepared spatial data is stored and readily available when contractors need to gather measurement information, eliminating the need for time-consuming site visits while maintaining measurement accuracy through the use of professional-grade aerial photography and automated 3D modeling.
Solution Approach 2:
The system creates digital copies of physical properties through three-dimensional models generated from aerial imagery. These virtual replicas contain all necessary measurement data and can be accessed remotely by contractors, providing an accurate copy of the physical space without requiring physical presence. The digital twin approach allows multiple contractors to review the same property data simultaneously without scheduling conflicts or travel time.
2Measurement precision
If contractors visit sites to collect information, then data accuracy improves, but operational costs increase
Solution Approach 1:
The system enables contractors to independently access and utilize property measurement data from pre-generated three-dimensional models without requiring site visit coordination or physical presence. Contractors can self-serve by reviewing aerial imagery and 3D models at their convenience, extracting necessary measurements for bidding purposes. This eliminates the need for property owners to coordinate contractor visits and reduces the operational burden on all parties involved.
Solution Approach 2:
The system introduces a digital intermediary layer between the physical property and the contractor through aerial imagery capture and three-dimensional modeling. This intermediary process, performed once by a drone operator and processor, creates a persistent digital representation that can be accessed by multiple contractors without requiring repeated physical visits. The intermediary data structure serves as a shared resource that maintains data accuracy while eliminating the need for costly and time-consuming site visits.
3Productivity
If multiple contractors are requested for bidding, then competitive pricing can be achieved, but coordination complexity increases
Solution Approach 1:
The system creates a universal data platform that serves multiple contractors simultaneously through a centralized online interface. The same three-dimensional model and aerial imagery can be accessed by any number of contractors who register on the platform, eliminating the need for separate coordination with each contractor. The system functions as a multi-user environment where property owners can post bidding requests once and receive competitive bids from multiple contractors without increased coordination burden.
