Construction / Materials
A LINE assistant that captures the full construction brief in one pass
Phak AI's front-line assistant is an AI assistant on LINE OA that handles inquiries for construction and building materials firms. It asks for what engineers need to know, such as location, size, and intended use, before handing off. It answers general questions from documents the company has approved and cites its sources, then sends a brief summary to the right engineer or salesperson. It suits firms where every deal goes through an engineer and leads slip away because replies come too late.
We want to add a warehouse behind our factory. What would it cost?
Three quick details before I pass this to an engineer: the location, rough floor area, and what you plan to store.

Why construction firms lose leads in the first chat
Clients ask for a budget before details
Clients want a budget and a model before meeting, but have not shared location, size, or use. The team has to ask several times.
Every chat waits for an engineer
Basic questions mix with ones that need an engineer. Few people can answer, so chats stall.
Channels tied to personal accounts
Clients message staff on personal phones or LINE accounts. When someone is busy or leaves, the lead goes too.
Some corporate clients write in English
Factories and firms with international teams ask in English, and the front desk has to find someone to reply.
How the construction LINE assistant works
It starts on the LINE OA you already use. Nothing to replace.
Set an intake checklist
The company decides what each job type needs, such as location, floor area, and intended use, and adds it to the knowledge base with past projects and product guides.
The assistant asks until the brief is complete
When a client messages the LINE OA, the LINE assistant asks for what is missing and answers general questions from approved documents, citing its sources.
Screen and summarize
The assistant turns the conversation into a short brief and separates jobs that fit your services from those that do not.
Hand off to an engineer
The brief goes to the engineer or salesperson in charge. People set the meeting, assess the job, and quote the price.
Not sure, no answer
For job-specific prices, structural questions, or special terms, the assistant does not guess. It passes the question to a person.

Frequently asked questions
Can the front-line assistant tell clients the price of a job?
The assistant collects the full brief and hands it to the person who quotes. If you want, it can also share a preliminary budget range from your approved price table, clearly marked as preliminary. Actual prices come from an engineer or the sales team.
Do we need a new LINE OA?
You can use your existing LINE OA. If you do not have one, setting it up is the first step of getting started, and it moves clients off staff members' personal accounts onto a company channel.
What happens when a client asks something that is not in the knowledge base?
The assistant does not guess. It tells the client a team member will follow up and forwards the question with a summary of the conversation to the person in charge.
Can the assistant reply in English?
Yes. The front-line assistant works in Thai and English, and it still answers from your approved documents and cites its sources.
