Custom gradient in delta elevation analytics
The user is a project manager who represents the owner and
supervises the general contractor in a new residential area project. This
project involves constructing new roads for a new neighborhood.
The general contractor submitted an 'As-Built' drawing of the pre-construction site condition to the owner for approval. This drawing will be added to the contract documents, serving as a baseline for volumetric calculations and project progress.
Pre-Construction ‘As Built’
Before incorporating it into the contract documents and commencing on-site work, the owner wanted to validate the 'As-Built' provided by the general contractor.
Roads Contour Lines
To verify the 'As-Built,' the owner generated a
pre-construction model of the jobsite using DatuBIM. Utilizing Delta
Elevation's Custom Color Gradient, the owner compared the elevations in the
contractor's 'As-Built' with those in DatuBIM. According to the project
specifications, a difference greater than 5 cm between the two surfaces is
considered a deviation, and a difference greater than 10 cm is deemed a critical
deviation. The user marked deviations in orange and critical deviations in red
using the Delta Elevation Custom Gradient tool.
The deviation between GC’s ‘As Built’ to DatuBIM
The tool provided an accurate pre-construction 'As-Built,'
saving the owner time and money by:
- Preventing future mistakes
- Enabling accurate volumetric calculations
- Eliminating the need for a survey crew on the jobsite
- Enabling accurate volumetric calculations
- Eliminating the need for a survey crew on the jobsite
Canal Area
As the project progressed, the owner wanted to tag areas
where the general contractor had achieved the designed cut/fill elevations. In
this case, he assigned a green color to areas where the delta between the
design and the current site elevation was under 10 cm.
The delta between the design to site elevation is under 10 cm.
Tips:
- Choose distinct colors for easier identification.
- Follow industry-standard color conventions collaboratively agreed by your peers, managers, and contractors.
- To add a color stop, click either on the bar or on the “+” button.
- Adjust the height of a color stop by dragging it to the left/right or by selecting it and entering the exact height on the textbox to the right.
- For a color cut instead of a gradient -
a. Place two color stops at the same height: one with the desired color and the other set to transparent.
b. Position the transparent color stop "above" the colored one.
