Submittals play a crucial role in the construction process, bridging the design phase and the actual construction work. They ensure that the materials, products, and methods used in a project align with the original design intent, specifications, and contractual agreements. In this comprehensive guide, we’ll explore the different types of submittals commonly used in construction and provide insights into how to optimize the submittal process for success.

What Are Submittals in Construction?

Submittals in construction are documents, samples, and other materials provided by contractors to the project’s design team—usually consisting of architects, engineers, and sometimes consultants—for approval before the work on site begins. Submittals serve as a verification tool to ensure that what will be constructed conforms to the design specifications and contractual agreements laid out at the start of the project.

The Importance of Submittals

Submittals are a critical part of the quality control process in construction. They allow the design team to verify that the proposed materials, products, and methods will work as intended. This step helps to avoid costly mistakes, rework, and delays by catching potential issues before they arise during construction. Moreover, submittals ensure that all stakeholders, including the owner, contractors, and design team, agree regarding the project’s execution.

The Purpose of Submittals

The primary purpose of submittals is to ensure that the materials and equipment used in construction align with the project’s design and specifications. They provide a means for architects and engineers to review and approve the products and methods contractors propose before implementing them on the construction site.

Submittals also serve as a communication tool that helps to:

• Confirm that materials and products meet the quality and performance requirements.
• Identify and resolve discrepancies between the design documents and the contractor’s proposed materials.
• Ensure compliance with regulatory standards and project specifications.
• Facilitate coordination among the various stakeholders involved in the project.

Types of Submittals in Construction

Several types of submittals are used in construction, each serving a different purpose in the project lifecycle. Below, we’ll explore the most common types of submittals and what they typically include.

Shop Drawings

Shop drawings are detailed plans or diagrams that illustrate how specific elements of a construction project will be fabricated or installed. They are often used for custom-made components or assemblies, such as structural steel, HVAC, and electrical systems. Shop drawings provide the design team with a clear understanding of how the contractor intends to execute the work and ensure that it conforms to the design intent.

Product Data

Product data submittals, or cut sheets, provide technical information about the materials, products, or systems proposed for use in the project. These documents typically include dimensions, material properties, performance characteristics, and installation instructions. They help the design team verify that the selected products meet the project specifications and are suitable for the intended application.

Samples

Samples are physical examples of the materials that will be used in construction, such as tiles, paint colors, or flooring materials. They are submitted to the design team for approval to ensure that the materials meet the aesthetic and quality standards specified in the project documents. Samples are particularly important for elements that significantly impact the visual appearance of the finished project.

Mockups

Mockups are full-scale models or prototypes of a particular part of the construction project. They are used to demonstrate the appearance, functionality, and construction methods of critical components before the actual work begins. Mockups allow the design team and the owner to assess and approve the workmanship and materials’ quality, helping avoid potential issues during the construction phase.

Engineering Calculations

Engineering calculations are often required for critical structural, mechanical, electrical, and plumbing systems to ensure that they meet the design requirements and safety standards. These calculations may include load-bearing analyses, voltage drop calculations, and HVAC performance assessments. Submitting these calculations allows the design team to verify that the proposed systems will function correctly and safely within the project’s parameters.

Vendor Information

Vendor information submittals provide details about the suppliers and manufacturers who will be providing materials and products for the project. This information helps the owner and design team ensure that the vendors meet the necessary qualifications and that their products comply with the project’s specifications.

Warranties and Manuals

Warranties and manuals are typically submitted towards the end of the project as part of the closeout submittals. Warranties provide documentation of the terms under which the manufacturer or supplier will repair or replace defective products, while manuals offer instructions on the operation and maintenance of installed systems and equipment.

As-Built Drawings

As-built drawings are the final set of drawings that reflect the actual conditions of the project after construction is completed. These drawings document any changes or deviations from the original design during construction. As-built drawings are essential for future maintenance, renovations, or additions to the building.

The Construction Submittal Process: Step-by-Step

The construction submittal process is multi-step and involves several key players, including the general contractor, subcontractors, and the design team. Below is a step-by-step breakdown of how the process typically unfolds.

1. Pre-Construction Phase

Before construction begins, the general contractor and the design team usually hold a pre-construction meeting to discuss the project’s requirements, including the submittal process. This meeting is crucial for setting expectations and clarifying the roles and responsibilities of each party involved in the submittal process.

2. Creating a Submittal Schedule

The first step in the submittal process is for the general contractor to create a submittal schedule. This schedule outlines the timelines for submitting and reviewing all required submittals, ensuring that materials and products are approved in time to meet the construction schedule. The submittal schedule is typically coordinated with the project’s overall timeline, prioritizing items with long lead times or critical path activities.

3. Preparing Submittal Documents

Once the submittal schedule is in place, the subcontractors begin preparing their submittal documents. This involves gathering all necessary information, such as shop drawings, product data, samples, and other relevant documents, and organizing them into a submittal package. Each submittal is typically accompanied by a transmittal form that provides details about the contents of the submittal and the corresponding specification section.

4. Reviewing and Approving Submittals

After the submittal documents are prepared, they are submitted to the general contractor for an initial review. The general contractor checks the submittals for completeness and conformity with the project specifications before forwarding them to the design team for approval. The design team reviews the submittals to ensure they meet the design intent and contractual requirements.

If a submittal is approved, it is returned to the contractor with an approval stamp, and the work can proceed. If revisions are required, the submittal is returned with comments, and the contractor must revise and resubmit it for further review.

The Role of RFIs in the Submittal Process

Requests for Information (RFIs) often play a critical role in the submittal process. Contractors use RFIs to seek clarification on specific aspects of the project design, specifications, or contract documents. They are particularly useful when preparing submittals, as they help ensure that the contractor fully understands the design team’s requirements before submitting documents for approval.

RFIs and submittals are closely related, as both are communication tools to ensure the project is executed according to plan. However, while submittals focus on the approval of materials and methods, RFIs are more concerned with resolving ambiguities and ensuring that all parties clearly understand the project requirements.

Challenges in the Submittal Process and How to Overcome Them

The submittal process can be complex and challenging, particularly on large or highly technical projects. Below are some common challenges encountered during the submittal process and strategies for overcoming them.

Submittal Tracking and Accountability

With multiple stakeholders involved and potentially hundreds of submittals to process, tracking the status of each submittal can be a daunting task. It’s crucial to have a system in place that tracks who is responsible for each submittal, its current status, and any required actions.

Solution: Implement a digital submittal management system that automates tracking and provides real-time updates on the status of each submittal. This helps to ensure that nothing falls through the cracks and that all parties are held accountable for their responsibilities.

Version Control

Managing different versions of submittals can be particularly challenging, especially when changes are made after initial submissions. Ensuring everyone is working from the most current version of a submittal is essential to avoid confusion and errors.

Solution: Use a cloud-based document management system that provides version control and allows all stakeholders to access the latest version of each submittal. This ensures that everyone is on the same page and reduces the risk of errors caused by outdated information.

Subcontractor Coordination

Coordination between subcontractors is essential to ensure their work aligns with the project plan. However, subcontractors often work in silos, leading to miscommunication and delays in the submittal process.

Solution: Regularly scheduled coordination meetings between subcontractors, led by the general contractor, can help align their efforts and ensure that submittals are submitted and reviewed promptly. Building Information Modeling (BIM) can also help visualize how different systems interact and identify potential conflicts before they occur.

Approval Delays

Delays in the submittal approval process can have a cascading effect on the project schedule, particularly if critical materials or systems are involved. Various factors, including unclear specifications, incomplete submittals, or slow response times from the design team can cause approval delays.

Solution: To minimize approval delays, ensure that submittals are complete and conform to the project specifications before submission. Regular communication with the design team and proactive follow-up on pending approvals can also help expedite the process. Additionally, prioritizing submittals based on their impact on the project schedule can prevent delays in critical areas.

Miscommunication

Miscommunication between the various parties involved in the submittal process can lead to errors, rework, and delays. This is particularly problematic in complex projects involving multiple subcontractors and suppliers.

Solution: Establish clear communication channels and protocols for the submittal process. This includes setting expectations for response times, documenting all communications, and holding regular progress meetings to address any issues. A centralized communication platform can also help ensure that all parties are informed and on the same page.

How Technology Can Streamline the Submittal Process

Advancements in technology have significantly improved the efficiency and effectiveness of the submittal process in construction. Digital tools and software solutions can help streamline the process, reduce errors, and improve stakeholder communication.
