Securing the right contractor is critical to the success of any tank construction project. A well-prepared request for proposal (RFP) ensures you receive accurate, comprehensive bids that align with your project’s specifications and expectations.
Contractor Qualifications
Choosing a qualified contractor is more than comparing prices—it’s about ensuring the team has the necessary experience, certifications, and capabilities to deliver a safe, compliant, and high-quality tank.
Not all tank contractors have the same capabilities. The customer must consider what qualifications are important to them and their project.
Key contractor qualifications to evaluate include:
- Experience with similar tank types and capacities
- API 650 and relevant code compliance
- Safety record and field personnel training
- Past project performance and client references
Using the API Tank Data Sheet
A cornerstone of the RFP process is the API Tank Data Sheet, found in Annex L of the API 650 standard. This structured document facilitates clear communication between owner and contractor by outlining all relevant design and construction parameters.
The data sheet includes:
- Design criteria (pressure, temperature, seismic zone)
- Roof type (fixed, floating, domed, etc.)
- Nozzles and manways
- Foundation details
- Coating and cathodic protection
- Testing requirements
- Shell capacity vs actual liquid capacity, vs useable capacity
- Information on specific site conditions like wind and seismic conditions
Completing this form thoroughly ensures proposals reflect accurate scope and budget expectations, reducing the likelihood of change orders and delays.
Evaluating the Proposal
When reviewing proposals, look beyond the price:
- Read the entire document, including all assumptions and exclusions.
- Evaluate the proposed schedule—check for realistic milestones and alignment with your overall project timeline.
- Clarify vague terms or unfamiliar scope items.
- Provide feedback to bidders to ensure understanding and allow for scope alignment.
Conclusion
A detailed and informed RFP process results in stronger bids, fewer surprises, and a more successful tank project. By emphasizing contractor qualifications and fully utilizing the API Tank Data Sheet, you lay the groundwork for a project that meets your performance, budget, and safety goals.
