Engineering Quantity Listing
Engineering quantity listing (EQL) is a critical resource in engineering work where detailed photographs and drawings are used to produce an accurate accounting of the quantities of construction materials required for a project. This detailed data is used by contractors to accurately price and track construction projects, develop cost estimates, and prepare bids for contracts. The list should provide all necessary information for the contractor to accurately price and track materials and construction tasks.
The engineering quantity listing is also useful in estimating the costs of a proposed project. During estimation, the contractor will compare the engineering quantity listing with site conditions, soil surveys, and other information to determine total costs. The list can be used to account for differences in the materials and anything that may impact the cost of a project. For example, if a given quantity needs to be additional or the item needs to be changed, the list can be updated to accurately account for those changes.
When preparing an engineering quantity listing, it is important to include accurate descriptions of the project materials, including the sizes and lengths of items, as well as the approximate weights. All measurements should be taken as accurately as possible, and the list should also include any special requirements or limitations that must be met when manufacturing or assembling different pieces. It is also critical to ensure that all quantities are correct, as any mistakes or miscalculations can quickly add up and significantly change the budget and construction timeline.
The engineering quantity listing should also include breakdowns of materials and labor costs, as well as permits and special certifications that may be required by local and state agencies. Although these items may be included in the base bid, they should be listed separately in the engineering quantity listing and help account for unforeseen costs.
Finally, it is important to review the engineering quantity listing with the project team and the contractor to ensure that all information is accurate and up-to-date. Any discrepancies should be addressed before bids are submitted and contracts are signed. With a thorough and accurate engineering quantity listing, projects will be able to be accurate and properly funded, saving time and money for all parties involved.
