Common Procurement Mistakes That Delay Major Capital Projects

Major capital projects are complex by nature. From energy infrastructure and industrial facilities to oil and gas developments, even well-planned projects can experience significant schedule and cost pressures.

One of the most common sources of these challenges is procurement.

Equipment, materials, specialized services, logistics, vendor documentation, and inspection activities must all arrive at precisely the right point in the project schedule. When procurement is treated simply as a purchasing function rather than an integral part of project execution, relatively small mistakes can create significant downstream consequences.

Understanding the most common procurement mistakes and addressing them early can help project owners protect schedules, control costs, and improve overall project performance.

Why Procurement Has Such a Major Impact on Project Delivery

Procurement sits at the intersection of engineering, construction, logistics, finance, quality, and project management. This interconnected approach is a core part of AhBe Global’s Engineering, Procurement and Construction (EPC) services, which support projects across the lifecycle from engineering design and procurement through construction and project execution.

An engineering team may complete its designs on schedule, but construction cannot proceed if critical equipment has not arrived. Similarly, equipment may reach the site on time but still cause delays if documentation, certifications, inspections, or installation requirements were not properly addressed.

Effective procurement therefore involves much more than issuing purchase orders.

It requires careful coordination throughout the project lifecycle.

1. Starting Procurement Too Late

One of the most damaging mistakes is waiting until engineering is substantially complete before beginning procurement planning.

Why this creates problems

Major projects often require specialized equipment with long manufacturing lead times. Depending on the project, these may include compressors, transformers, turbines, pressure vessels, switchgear, pumps, control systems, and other engineered equipment.

Discovering a 30- or 40-week lead time late in the project can immediately threaten the construction schedule.

A better approach

Procurement planning should begin during the early engineering phases.

Potential long-lead items should be identified as early as possible so that engineering, vendor engagement, technical evaluations, and purchasing activities can be appropriately sequenced.

2. Selecting Vendors Based Primarily on Price

The lowest quotation does not necessarily represent the lowest project cost.

A supplier offering a lower initial price may introduce additional risks through poor quality, unreliable delivery, inadequate documentation, limited technical support, or weak manufacturing capabilities.

Evaluate total value instead

Vendor evaluation should consider factors such as:

• Technical capability
• Manufacturing capacity
• Quality systems
• Relevant industry experience
• Delivery performance
• Financial stability
• HSE performance
• After-sales support
• Lifecycle costs

A slightly higher initial purchase price may ultimately save significantly more by preventing delays, failures, rework, and operational problems.

AhBe Global’s Procurement & Supplies services support equipment sourcing and engagement with Original Equipment Manufacturers (OEMs), helping clients consider not only initial procurement requirements but also warranties, technical support, and asset lifecycle needs.

3. Failing to Identify Long-Lead Equipment Early

Long-lead equipment can effectively determine a project’s critical path.

If these items are not identified during early project planning, the procurement schedule may become incompatible with the construction schedule.

A strong procurement strategy establishes a long-lead equipment register early and continuously updates it as engineering progresses.

This gives project teams greater visibility into potential schedule risks before those risks become actual delays.

4. Poorly Defined Technical Specifications

Suppliers can only provide accurate quotations and equipment when project requirements are clearly defined.

Incomplete or ambiguous specifications frequently result in:

• Incorrect vendor assumptions
• Multiple clarification cycles
• Change orders
• Equipment modifications
• Rework
• Commercial disputes
• Delivery delays

Engineering and procurement teams should therefore work closely together before Requests for Quotation (RFQs) are issued.

The goal should be to ensure vendors receive sufficiently detailed technical requirements to understand exactly what is expected.

5. Weak Coordination Between Engineering and Procurement

Engineering and procurement cannot operate as separate functions on a major capital project.

Design changes affect purchased equipment.

Vendor information affects engineering.

Equipment dimensions affect civil and structural design.

Electrical loads affect power systems.

Instrument requirements affect control architecture.

Successful projects establish clear communication channels between engineering, procurement, construction, and project management from the beginning.

This integrated approach is central to effective Engineering, Procurement and Construction (EPC) project delivery.

6. Ignoring Logistics Until Equipment Is Ready to Ship

Purchasing equipment is only part of the procurement process.

The equipment still needs to reach the project site.

For international and remote projects, logistics planning can involve:

• Freight arrangements
• Customs clearance
• Import permits
• Duties and taxes
• Port handling
• Heavy-haul transportation
• Route surveys
• Temporary storage
• Site access restrictions

Large equipment may even require road modifications, lifting studies, specialized trailers, or temporary infrastructure.

Logistics planning should therefore begin well before equipment leaves the manufacturer’s facility.

7. Inadequate Supplier Quality Surveillance

Waiting until equipment arrives at the project site to identify manufacturing defects can be extremely costly.

For critical equipment, procurement strategies should incorporate appropriate supplier quality activities such as:

• Inspection and Test Plans (ITPs)
• Manufacturing inspections
• Material verification
• Factory Acceptance Testing (FAT)
• Documentation reviews
• Non-conformance management

Organizations can reference internationally recognized quality-management principles such as those established by the International Organization for Standardization (ISO) when developing supplier quality systems.

8. Poor Vendor Documentation Management

Equipment documentation is often just as important as the equipment itself.

Projects may require:

• Data sheets
• Engineering drawings
• Material certificates
• Inspection reports
• Operating manuals
• Maintenance manuals
• Spare-parts lists
• Certificates of conformity
• As-built documentation

Late or incomplete vendor documentation can delay engineering approvals, commissioning, regulatory acceptance, and final project handover.

A structured Vendor Document Register (VDR) should therefore form part of the procurement process.

Document control becomes even more important when vendor information must remain coordinated with engineering approvals and regulatory requirements. Our article on digital permitting and compliance for industrial projects explores how better document management, revision tracking, and approval workflows can help reduce project delays and rework.

9. Failing to Account for Supply Chain Risk

Modern capital projects frequently rely on global supply chains.

That introduces exposure to risks including geopolitical disruption, transportation constraints, material shortages, currency volatility, supplier insolvency, extreme weather, and regulatory changes.

Project teams should evaluate supply-chain risks early and develop appropriate mitigation strategies.

These may include:

• Alternative suppliers
• Dual sourcing
• Strategic inventory
• Early purchasing
• Regional sourcing
• Schedule contingencies

Supply-chain resilience should be treated as a project risk-management issue rather than simply a procurement concern.

10. Poor Expediting and Vendor Follow-Up

Issuing a purchase order does not mean procurement is complete.

Suppliers must be actively monitored throughout manufacturing and delivery.

Effective expediting tracks critical milestones including:

• Engineering document submissions
• Material procurement
• Manufacturing progress
• Inspection dates
• Factory testing
• Shipping readiness
• Transportation
• Final delivery

Early visibility allows project teams to intervene before minor supplier delays become critical project delays.

The Cost of Procurement Mistakes

Procurement failures rarely remain isolated within procurement.

They can trigger cascading consequences throughout a project.

Late equipment may idle construction crews.

Incorrect equipment may require redesign.

Missing documentation may delay commissioning.

Poor-quality components may create reliability problems long after the project enters operation.

Ultimately, procurement performance directly influences project cost, schedule, quality, safety, and long-term asset performance.

Building a More Integrated Procurement Strategy

The strongest procurement strategies begin during project planning and remain integrated with engineering, construction, quality, logistics, and project controls throughout execution.

Organizations such as the Project Management Institute emphasize the importance of coordinated project planning and risk management across major projects.

This integrated model becomes even more important as organizations invest in new forms of energy infrastructure. As discussed in our guide to the role of EPC companies in renewable energy projects, coordinated engineering, procurement, construction, commissioning, and project management can help organizations reduce project risk and improve delivery performance.

For owners developing complex industrial or energy infrastructure, working with an experienced engineering and project delivery partner can provide additional technical oversight throughout procurement and execution.
