Overview

Before having CEC-Onsite System, Construction workers at CEC had mainly employed traditional methods of using paper to record their construction process. The working environment of construction workers is humid and muddy. Therefore, all the paperwork will be wet and soft when they are filling the form. The only equipment that will prevent this situation is using the phone to record these quality checking details.

Due to NDA, I’m not allowed to reveal complete design processes and deliverables. All the data is redacted and blurred and would be used for portfolio building only.

Impact

Planning and designing the biggest construction corporation in Taiwan for digital transformation, the system created over 89% of construction projects that have already used the app and website, and this increased by 45% work efficiency.

01 Challenges

Original Checking Process

Step 1: Take Pictures through phone

Construction workers take pictures when they check items.

Step 2: Fill in paper forms

Construction workers fill in forms and match pictures they have taken.

Step 3: Pass the standard or not

Construction managers and department of quality control decide if this item pass the standard or not and decide if it need to be iterate.

02 Problems

Quality control of construction sites had been questioned.

CEC didn't have accurate historical data to track and supervise every construction site.

Items that didn't pass the standard can't be awarded immediately.

Before using concrete and stainless steel provided by suppliers, construction workers had to take a sample and run tests. But headquarter of quality department wouldn’t know immediately.

Forms and pictures were not matching

Due to workload and working place differences, construction workers preferred to fill in forms and uploaded photos on the due date.

03 Design Questions

How we can design a system that can use in different scenarios, not just for typing in the office, but also let construction workers can check all the items when they are on-site?

How we can think of connection issues when they are in the construction site and encourage construction workers use phone to document checked items?

How we can make sure all the information can be type printed in to A4 size paper and be signed by all the supervisor online?

04 Before / After

Before

All the documents are printed and stored in the office due to some of the documents need to be printed and mailed to the government.

After

[App for construction workers]

For construction workers, they can simply use app to fill in self-inspection checklist to take pictures and at the same time.

After

[Website for department of quality control]

For quality control department, they can through website to check all the construction project and approved all the requested and signed it when you approved it.

05 Design Highlights

Self-check Inspection List

→ Breaking paper form information into different sections and create photo features to let users sync all the data at the same time

App

Instead of letting construction workers collect all the information and then back to the office and type it again.

I designed cec-onsite app for construction workers to record all the information in seconds.

Step 1 Fill in basic information

Step 2 Writing down the detail

Step 3 after submit, choose a member to hand over the form

Step 4 Quality control also can see the form through web platform

Trend Analysis

→ Collect all the information into the platforma but still display as a paper form for printing.

App

After construction workers checking the quality of the item, they also need to take the sample to test it out the quality. All the data will be collect to the headquarter and the will able to see all the sampling data and calculate if this supplier pass the quality standard or not.
