Maintenance, Engineering, Construction Logistics, and Field Operations in One Platform

ARWA is a connected multi-vendor marketplace designed to bring property owners, maintenance companies, field technicians, consulting engineers, equipment providers, and construction suppliers into one operational ecosystem.

The platform combines air-conditioning, swimming pool, elevator, and home-appliance maintenance bookings with engineering consultations, HVAC load calculations, blueprint uploads, construction equipment rentals, air-system commerce, and building-material exchange.

The ARWA ecosystem includes a Customer Mobile Application, a Technician Mobile Application, a Service Provider Web Portal, a centralized Administration Dashboard, a public website, and a secure API backend.

Administrators can activate or deactivate individual service modules by country, allowing the platform to adapt to different regional operations and market requirements.

Project Overview

ARWA was developed to transform fragmented maintenance, engineering, and construction service workflows into one organized digital journey.

Customers can select a service, define the property location, describe the requirement, upload images or engineering files, and submit the request to an approved company or consultant.

Service companies receive requests through their portal, review the requirements, propose visit times, and assign qualified technicians according to specialization and availability.

Assigned technicians receive task, customer, location, and scheduling details through a dedicated mobile application and update the work status during travel, arrival, execution, and completion.

ARWA also supports advanced technical workflows, including room and building information collection for HVAC load calculations, BTU and CFM requirements, and PDF or AutoCAD blueprint submissions.

Additional marketplace modules support heavy equipment rentals, direct air-conditioning and ventilation product sales, building-material trading, property classifieds, and technical job opportunities.

The Business and Operational Challenge

Property owners often struggle to find reliable maintenance companies, technicians, and consulting engineers in a fragmented service market.

Manual communication creates delays when requesting quotations, arranging appointments, confirming visits, and coordinating field employees.

Service companies also experience scheduling conflicts and inefficient technician allocation when bookings, employee availability, and customer approvals are managed through disconnected tools.

Engineering services such as HVAC calculations, elevator proposals, pool projects, and blueprint reviews require documents and structured technical information that are difficult to manage through phone calls and messaging applications.

Construction projects face additional sourcing challenges when renting machinery, finding materials, or trading project surplus without a dedicated marketplace.

The platform therefore required a centralized and scalable solution connecting field operations, engineering files, service providers, commerce, rentals, and regional configuration.

The Thotix Solution

Designed and developed by Thotix, ARWA provides one digital ecosystem for customers, service companies, technicians, consulting engineers, suppliers, and platform operators.

The service workflow begins with discovery and request submission, continues through review, scheduling, and technician allocation, and ends with field execution, completion, and rating.

The Service Provider Portal enables companies to manage technicians, specializations, availability, requests, schedules, assignments, and customer feedback.

The Technician Application provides direct access to assigned work, customer information, geographical locations, visit schedules, and operational status controls.

Engineering, equipment rental, product commerce, and materials exchange modules are integrated into the same backend rather than operating as disconnected systems.

The Administration Dashboard controls provider verification, requests, calculation parameters, countries, modules, marketing, notifications, reviews, and reports.
