Commercial Construction

---

These projects are mainly divided into 3 levels on the basis of their size, resources, cost estimates and complexities and these three levels are as follows:

The projects that involve repairs or maintenance, renovations and minor explansions of already constructed buildings such as retail space, updating of office space interiors, or small additions to a building. These projects are generally completed quickly with minimal personnel and lower costs.

These projects are mostly extensive and mainly include significant renovations, expansions, or new builds up to 50,000 square feet. Examples include adding a new wing to a hospital or constructing a mid-sized office building. These projects are more difficult and  need more time to execute, often needing a construction team or a full team of professionals.

Large-scale projects include constructing entirely new buildings from the ground up, such as skyscrapers, large commercial centers, or industrial complexes. These projects are highly complex, require extensive planning and coordination, and often take several years to complete. They involve large teams, specialized equipment, and significant financial investment​ 

Completing a commercial building construction project involves several critical phases, each with its own set of tasks and responsibilities. A construction manager plays a pivotal role in coordinating and managing the project from inception to completion, ensuring effective communication among all parties involved. Here’s a detailed overview of each phase of building project:

This starting phase sets the foundation for the entire project. It involves selecting the project site, a general contractor, setting a budget, and defining the project’s scope. Key activities include:

• Site Selection: Selected location is based on factors like accessibility, zoning laws, and market demand.
• Budgeting: Work with financial experts to establish a realistic budget that covers all anticipated costs, including land acquisition, materials, labor, and contingency funds.
• Design and Planning: Teamup with architects and engineers to create preliminary designs and site plans. This stage includes feasibility studies, environmental impact assessments, and securing initial permits​.

Once the planning stage is complete, the project moves into pre-construction, which involves detailed preparations before any physical work begins:

• Finalizing Designs: Convert preliminary designs into detailed architectural and engineering plans,  making sure compliance with building codes and regulations.
• Permitting: Obtaining all  required permits and approvals from local authorities, including zoning permits, environmental permits, and building permits.
• Site Preparation: Conduct site investigations, including soil testing and environmental assessments, to make sure the land is suitable for construction.
• Hiring Contractors: Select and contract with general contractors and subcontractors who carry out all the construction work​.

In this phase, all the materials, equipment, and services needed for the construction are acquired:

• Sourcing Materials: Purchase construction materials such as steel, concrete, and glass, ensuring they meet the project’s specifications and quality standards.
• Equipment Procurement: Secure the necessary construction equipment, either through purchase or rental.
• Contractor Coordination: Coordinate with suppliers and subcontractors to make sure timely delivery of materials and services to the construction site​.

In this step, construction begins with the physical construction of the building taking place during this phase:

• Site Preparation: Clear the site, perform excavation work, and lay the foundation.
• Building Structure: Erect the building’s framework, including structural steel, concrete, or wood, followed by the installation of walls, roofing, and floors.
• Systems Installation: Install essential systems such as electrical, HVAC, plumbing, and fire safety systems.
• Interior and Exterior Work: Complete the interior spaces with walls, ceilings, and flooring, and finish the exterior with cladding, windows, and doors​.

After construction, the whole project team enters its final phase, focusing on inspections, testing, and turnover:

• Inspections and Testing: Conduct final inspections to ensure the building meets all safety codes and quality standards. This may include testing electrical systems, plumbing, and other critical installations.
• Punch List: Make a punch list of minor items that need to be corrected or completed before final acceptance.
• Project Handover: Once all work is complete and meets the required standards, hand over the building to the owner. This includes providing all necessary documentation, such as warranties and operation manuals.
• Occupancy Permit: Obtain an occupancy permit from local authorities, allowing the building to be used for its intended purpose​

The construction bidding process is a structured procedure within the construction industry where contractors submit proposals to complete a project. Here’s a summary in five key points:

1. Invitation to Bid (ITB): The process begins when a project owner or developer issues an ITB or Request for Proposal (RFP). This document outlines the project’s scope, specifications, timeline, and any specific requirements, inviting qualified contractors to submit bids.
2. Bid Preparation: Interested contractors prepare their bids by estimating costs for labor, materials, equipment, and overhead, often including contingencies for unforeseen expenses. This step may also involve seeking quotes from subcontractors and suppliers.
3. Bid Submission: Contractors submit their completed bids by a specified deadline. Bids typically include a breakdown of costs, project timelines, and any qualifications or assumptions. The submission must meet all requirements outlined in the ITB or RFP to be considered valid.
4. Bid Evaluation: The project owner evaluates the submitted bids based on criteria such as cost, contractor experience, proposed timelines, and overall value. The evaluation may involve multiple rounds of review, including clarifications or negotiations with bidders.
5. Contract Award: After the evaluation, the project owner awards the contract to the selected bidder, often the one offering the best combination of price and qualifications. A formal contract is then signed, outlining the case of the agreement, including payment schedules, project milestones, and performance expectations​

• It typically includes the project scope, a detailed cost breakdown (covering materials, labor, and equipment), and the proposed project timeline. It may also include terms and conditions, payment schedules, and any qualifications or exclusions that might affect the project documents final cost.
