Service Overview
Bills of Quantities and Specifications (BOQ) represent the backbone of any successful tendering process, providing a unified and precise language between the owner and the contractor and ensuring full transparency in cost estimation. We offer a comprehensive service for preparing BOQs, which serve as a highly important legal, technical, and financial document in project management.
Through our team of quantity surveyors and certified estimators, we ensure the delivery of accurate and comprehensive schedules covering all work items, materials, and equipment required for project execution. Our work goes beyond mere quantity take-offs, providing detailed cost analysis, precise material specifications, and execution methods, enabling effective budget management and avoiding unexpected expenses.
We operate according to the latest international standards in work item classification and use the most advanced specialized software for measurement and pricing. We understand that the accuracy of BOQs directly impacts project success, which is why we adopt a multi-stage methodology for verification and review to ensure the schedules are free from errors or omissions.

- Reducing disputes and conflicts with contractors
- Improving procurement efficiency and material management
Implementation Process and Phases
Our journey in preparing Bills of Quantities and Specifications begins with an in-depth study of the drawings and design documents, where we analyze all elements and systems and understand their interrelationships. We then move to the precise measurement of quantities according to the latest approved measurement methods, paying close attention to details and the relationships between different work items.
We follow a systematic methodology that starts with logically dividing the project into main work packages, then breaking each package down into detailed items. During the preparation process, we ensure integration between different items and the comprehensiveness of specifications and execution requirements. We document all assumptions and conditions on which the schedules are based to ensure full transparency.
Comprehensive Study and Requirements AnalysisWe review all drawings and documents, understand the scope of work, and prepare the project breakdown structure.
Precise Measurement and Quantity PreparationWe accurately measure quantities for all work items, ensure completeness, and classify the items according to systems.
Preparation of Specifications and ConditionsWe prepare detailed technical specifications, define quality and execution requirements, and ensure contract conditions are included.
Pricing and Financial AnalysisWe analyze market prices, prepare pricing items, and conduct a detailed analysis of direct and indirect costs.
Final Review and Delivery We perform a comprehensive review of the schedules, ensure their accuracy, and deliver the final document along with an execution summary.
Technologies and Tools Used in Preparing Bills of Quantities and Specifications
We use advanced measurement software such as CostX and Bluebeam to automate the measurement process and ensure accuracy. We rely on standardized classification systems such as MasterFormat and Uniclass to organize work items. We also apply techniques to link measurements directly with 3D models from BIM.
We integrate local and international price databases for accurate pricing and use document management systems to ensure version control. Additionally, we employ advanced quantitative analysis tools to improve estimation accuracy and determine margins of error.
BOQ focuses on quantities, execution activities, their specifications, and costs, serving as a contractual document between the owner and contractor. In contrast, BOM (Bill of Materials) is a list of materials and components required for manufacturing or construction without focusing on execution activities and costs. BOQ is more comprehensive, including work activities, materials, equipment, and labor.
We use a "contingency allowance" system for uncertain items, providing a detailed description of the assumptions and conditions on which these items will be measured later. We also offer alternatives and solutions to mitigate financial risks associated with these items.
For projects with complete design documents, the margin of error does not exceed 3–5%, while in projects with incomplete designs, it may reach 10–15%. We work to reduce this margin through multiple reviews and detailed analysis.
Yes, BOQs can be used throughout the project lifecycle: during the tender stage to compare competitors, during execution to track quantities and payments, and during handover for final settlements. They are also used as a basis for managing changes and modifications.
We follow a systematic change management process, updating the BOQs according to the latest version of the drawings, documenting all modifications, and specifying their impact on cost and schedule. We provide periodic reports detailing all changes and their effect on the budget.
