MTO, BOQ & BOM Preparation Services
Accurate material take-off, bill of quantities, and bill of materials preparation from engineering drawings — supporting procurement, estimation, and construction activities across Saudi Arabia.
SLETEC Engineering provides MTO (Material Take-Off), BOQ (Bill of Quantities), and BOM (Bill of Materials) preparation services for engineering and construction projects across Saudi Arabia. Our quantity and materials team extracts precise quantities from engineering drawings, specifications, and equipment datasheets, delivering structured, procurement-ready documents that support cost estimation, tendering, and material procurement activities.
For oil & gas and petrochemical projects, piping MTO preparation is one of our most frequent services — extracting pipe, fittings, flanges, valves, gaskets, and bolting from isometric drawing packages organised by line number, size, material class, and specification. Structural steel MTOs include member weights, connection hardware, and coating quantities. Civil BOQs cover earthworks, concrete, formwork, reinforcement, and builder's work items in a tendering-compliant format.
BOM preparation for mechanical equipment and fabricated assemblies draws quantities from 3D CAD models, assembly drawings, and design specifications. SLETEC produces BOMs in hierarchical format with part numbers, descriptions, quantities, material specifications, and procurement lead time flags where relevant. All MTO, BOQ, and BOM deliverables are formatted to client templates or project-standard formats and delivered in Microsoft Excel with PDF summary copies.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Excel-based deliverables with structured formatting, filter functions, and pivot-ready layouts for direct integration with procurement workflows.
MTO reconciliation service available — comparing original MTO against procured quantities to identify surplus, shortfall, and scope changes.
Experienced with Saudi Aramco and SABIC material master codes for MTO preparation aligned with client procurement databases.
Frequently Asked Questions
What is the difference between MTO, BOQ, and BOM in engineering projects?
MTO (Material Take-Off) is a quantified list of materials extracted from engineering drawings for procurement purposes, typically used in piping, structural, and civil disciplines. BOQ (Bill of Quantities) is a structured cost-estimating document used in construction projects to define scope items and quantities for tendering. BOM (Bill of Materials) is a hierarchical list of all components in a manufactured assembly, used in fabrication and product manufacturing contexts. SLETEC prepares all three types for engineering and construction projects.
How does SLETEC prepare piping MTOs in Saudi Arabia?
SLETEC prepares piping MTOs by reviewing piping isometric drawings, line lists, and pipe class documents to extract all pipe, fittings, flanges, valves, gaskets, bolting, and insulation materials for each line. The MTO is formatted in accordance with client templates and grouped by material type, size, and specification to facilitate procurement.
Can SLETEC prepare BOQs for civil and structural construction in KSA?
Yes. SLETEC prepares civil and structural BOQs covering earthworks, concrete, formwork, reinforcement, structural steel, piping, and general builder's work items. BOQs are formatted per project tendering requirements with clear descriptions, units, and quantities ready for contractor pricing.
What deliverable format does SLETEC use for MTO and BOQ reports?
MTO, BOQ, and BOM reports are delivered in Microsoft Excel format with clearly structured worksheets, filter-ready columns, and summary tabs for category-level quantity summaries. PDF versions are also provided. We can adapt the format to client or project-specific templates where required.
