S
Schedule of Values
Definition: a statement provided by the contractor to the architect, outlining the distribution of the contract sum across different work components. This serves as the foundation for assessing the contractor’s payment requests during project progress.
-
Maintain a transparent and detailed schedule of values to facilitate accurate financial tracking and fair payment evaluations.
Shop Drawings
Definition: detailed construction drawings, diagramas, illustrations, schedules, performance charts, brochures and other data created by contractors or subcontractors, outlining how specific project components will be fabricated, assembled, and installed.
-
The contractor submitted shop drawings for the steel beam connections, clarifying the intricate assembly process to ensure accurate construction.
-
Review shop drawings meticulously to ensure alignment with design intent and project specifications before granting approval. This helps prevent discrepancies during construction and ensures accurate implementation.
Specifications
Definition: detailed written descriptions that outline the precise requirements, standards, and quality expectations for materials, equipment, and workmanship in a construction project. They provide a comprehensive guide that ensures uniformity, compliance, and the desired outcome.
-
Specifications are the backbone of any construction project, serving as a critical communication tool between project owners, architects, engineers, and contractors. They clarify the materials to be used, construction techniques, performance standards, and other essential details, ensuring that everyone involved is on the same page.
-
Specifications help maintain the project's integrity, quality, and safety by preventing misunderstandings and deviations from the original design intent. They enable accurate cost estimation, material selection, and regulatory compliance.
-
Whether it's defining the strength of concrete, the thickness of insulation, or the finish of interior surfaces, specifications play a vital role in the successful execution of construction projects.
Submittals
Definition: various documents, samples, and materials submitted to the architect for review and approval. These submissions provide a means for contractors and suppliers to demonstrate compliance with project specifications, codes, and standards.
-
Key components of submittals typically include: product data, shop drawings, material samples and mock-ups.
These submissions allow the project team to evaluate the proposed materials, equipment, and systems for compatibility, functionality, and compliance.
-
The review process ensures that the project meets the required standards and specifications, also providing an opportunity for value engineering and improvement.
Substantial Completion
Definition: refers to the stage of a construction project where the work is considered to be sufficiently finished, allowing the owner or client to use or occupy the building or facility for its intended purpose. Although minor items or finishing touches may remain, substantial completion marks a significant milestone in the project’s progress.
-
According to Section 2 of the Ontario Construction Act, a contract is considered to have been substantially performed when the work or a significant part of it is ready to be used as intended. It means that the improvements made under the contract should be in a state where they can be used.
However, there can still be minor defects or corrections to be made. The contract can still be considered substantially performed if the cost to fix those defects or corrections is less than a certain percentage of the contract price. The specific percentages are as follows:
three percent of the first $1,000,000 of the contract price;
two percent of the next $1,000,000 (if applicable); and
one percent of the remaining contract price (if applicable).
-
This provision allows for some flexibility in determining substantial completion while considering minor remaining work.
-
Certificate of Substantial completion is a certified statement, prepared by an architect on the basis of his inspection:
a) Stating that the work, or designated portion thereof, is substantially complete and ready for occupancy for its intended use;
b) establishing the date of substantial completion;
c) defining the interim responsibilities of the owner and the contractor for the provision of heat, maintenance, and security, and for possible damage and insurance; and
d) fixing the time within which the contractor shall complete the items in the inspection list.
The Certificate of Substantial Completion serves as an important milestone in the construction process. It enables the owner to take possession of the completed project, initiate operations, and begin the warranty period. It also marks the point at which certain contractual obligations and responsibilities, such as insurance coverage and liability, may shift from the contractor to the owner.
Supplemental Instructions
Definition: an instruction that does not involve adjustments to the Contract Price or Contract Time. It can come in various forms, including: specifications, drawings, schedules, samples, models, or written instructions. These instructions are crucial for performing the Work in accordance with the Contract Document’s intent.
-
Pay close attention to supplemental instructions and ensure clear communication with all stakeholders. Understanding and implementing these instructions accurately can prevent misunderstandings and delays. Stay proactive and seek clarification when needed, to ensure a successful project outcome.
Supplementary Conditions
Definition: a critical component of construction contracts. They are additional terms and specifications that modify or complement the general conditions of a contract. These conditions are tailored to the specific project and may address unique requirements, standards, or procedures.
-
Supplementary Conditions serve to provide clarity and customization in construction contracts. They can cover a wide range of project-specific details, including regulatory compliance, safety protocols, scheduling constraints, and more. These conditions are essential for aligning the contract with the unique needs and complexities of each construction project.
-
Supplementary Conditions play a pivotal role in tailoring a contract to the project's exact specifications, ensuring that all parties understand their roles, responsibilities, and the specific requirements that apply to their work. They promote transparency, mitigate risks, and contribute to the successful execution of construction projects.
U
Unit Price Contract
Definition: contracts that offer an innovative solution. Instead of a fixed sum, it sets prices for specific work items. But here’s the twist: the final payment depends on the actual quantity of work completed, calculated using these unit prices. This approach not only fosters flexibility in construction projects but also maintains fairness by linking payments directly to the work accomplished.
-
A project where certain aspects are uncertain or where adjustments might be needed: Unit Price Contracts provide the agility to handle such situations. From unexpected scope changes to fluctuating quantities, this contract type ensures projects stay on track.
-
Transparent, adaptable, and efficient—Unit Price Contracts empower construction teams. They encourage responsive decision-making, allowing adjustments as the project evolves. Plus, they foster trust by clearly tying payments to actual progress, making everyone's job a whole lot smoother.
-
This contract comes with its own disadvantages:
The maximum cost for a project is uncertain at best, making accurate financial planning challenging.
Additionally, the unit cost is based on an estimate of material quantity derived from bid documents; if quantities vary considerably during construction, the unit costs may also fluctuate.
Despite these challenges, Unit Price Contracts remain a dynamic tool in the construction industry, bridging the gap between flexibility and financial certainty.
