Storage Tank Tender Documents Preparation & Cost Estimation – Wisdom Engineering Services

​

​

At Wisdom Engineering Services, we provide comprehensive support for the preparation of storage tank tender documents and cost estimation. Our services ensure that the entire process, from designing and detailing specifications to cost analysis and material requirements, is carried out accurately, efficiently, and in line with industry standards. Here's an overview of the key components we offer in our storage tank tender preparation:

​

1. Specifications

• Tank Design and Standards: Detailed specifications for the tank, including materials, dimensions, and compliance with relevant standards such as API 650, and ASTM.

• Performance Criteria: Operational parameters such as the tank's intended use (e.g., liquid storage, pressure rating, temperature range), as well as safety and durability standards.

• Material Selection: Specifications for the types of materials used, including carbon steel, stainless steel, or special alloys, depending on the storage requirements and environmental factors (corrosion, temperature, etc.).

• Welding and Fabrication: Details on welding processes, inspection, and quality control to ensure structural integrity and leak prevention.

• Corrosion Protection: Methods for internal and external corrosion control, such as coatings, cathodic protection, or corrosion-resistant materials.

• Operational and Safety Features: Specifications for safety valves, pressure relief systems, gauges, and other accessories.

​

2. General Arrangement (GA) Drawing

• Tank Layout: Detailed General Arrangement (GA) drawings that provide a visual representation of the tank, including shell height, diameter, roof design, bottom design, inlet/outlet piping, and safety features.

• Structural Details: Clear depiction of the tank’s structural elements such as supports, wind girders, and anchorage systems.

• Piping and Instrumentation: Layout of the tank’s piping system, with connections for inlet/outlet lines, overflow, vents, and drains.

• Seismic and Wind Load Analysis: Incorporation of seismic considerations and wind load design elements into the drawings to ensure structural stability.

• Access and Maintenance Features: Design for ladders, walkways, inspection hatches, and manways for ease of operation and maintenance.

​

3. Bill of Materials (BOM)

• Material Quantification: A detailed list of all materials required for the construction of the tank, including shell plates, roof materials, bottom plates, nozzles, bolts, and welding consumables.

• Component Specifications: Specifications for each component (e.g., thickness, dimensions, material grade) to ensure consistency and quality.

• Procurement Requirements: Identification of any special materials or components that may require long lead times or specialized sourcing.

• Manufacturing and Fabrication: A breakdown of all components, including how they will be fabricated, sourced, and assembled.

​

​

4. Total Cost Estimation

• Material Costs: Estimation of the total material cost based on the BOM, including steel, coatings, insulation, and other components.

• Fabrication and Labor Costs: Estimation of labor costs for tank fabrication, welding, and assembly, including site-specific labor rates and the time required for construction.

• Transportation and Installation: Cost estimation for transportation of the tank components to the site and on-site installation, including labor and equipment for tank erection.

• Quality Assurance and Inspection: Costs for material testing, welding inspection, and compliance with safety and regulatory standards.

• Contingency Costs: An allowance for unforeseen circumstances or changes in the scope of work that may arise during project execution.

• Total Project Cost: A comprehensive total project cost, combining all material, labor, equipment, and installation costs, including overheads and any additional service charges.

​

5. Project Schedule & Milestones

• Timeline: A detailed project timeline with milestones for each phase of the tank's construction, from procurement to installation.

• Project Phases: Break-down of the project phases, including engineering design, material procurement, fabrication, assembly, site preparation, and final commissioning.

​

6. Tender Submission & Documentation

• Tender Documentation: Preparation of all necessary tender documentation to submit to clients, including the technical specifications, drawings, and detailed cost estimates.

• Bid Evaluation: Support for evaluating bids from suppliers and contractors based on the submitted tender documents, ensuring compliance with specifications and cost constraints.

• Contract Terms: Assistance in drafting and reviewing contract terms, timelines, and payment schedules to ensure alignment with the client's expectations.
