Sample Expert Assignment Scenario – Architectural Implementation Errors and Material Discrepancies in a Luxury Residential Project
🎯 Assignment Overview:
Evaluation of a technical dispute between the employer and the contractor regarding material selection and workmanship quality in a high-end residential project, and preparation of an impartial resolution report.
👥 Parties Involved:
• Employer: A private investor based in Switzerland
• Service Provider: An Austria-based architectural execution company specializing in luxury residences
🏠 Project Summary:
The interior architectural implementation for a first-class luxury villa project in Zürich was awarded to an Austria-based firm via the Tenderely platform.
The contract scope includes:
• Interior ceiling and floor finishes
• Fixed furniture
• Bathroom fixtures
• Wall coverings
• Electrical and electronic system fittings
All design work was carried out by a separate architectural office appointed by the employer. Drawings and technical specifications were provided to the contractor for execution.
⚠️ Subject of Dispute:
After completion, the employer filed the following technical complaints:
• Flooring: Locally sourced marble was used instead of the approved Italian marble
• Bathroom Fixtures: Products installed were from different brands than those specified in the technical documentation
• Furniture Workmanship: Wardrobe doors in the bedroom were misaligned and corners were sharp
• Lighting Fixtures: Products installed were not in line with the original architectural plans
• Lack of Communication: Material changes were made without prior consultation with the employer
The service provider presented the following defenses:
• All product substitutions were made due to unavailability of original items, using equivalent alternatives of similar quality
• Material selections met technical requirements and were functionally equivalent
• All on-site changes were communicated to the employer’s representative through the platform's messaging system
• Installations and fabrication were carried out in accordance with European standards, and the observed issues may be user-related

4. Assess whether the final implementation aligns with the project's aesthetic, functional, and technical objectives
5. Perform on-site inspection if necessary
6. Prepare a technically justified and impartial resolution report for the parties
📄 Expert Report Must Include:
• Project summary and positions of both parties
• Compliance analysis of each material and design detail
• Observational assessment of installation and fabrication errors
