• Checking for construction moratoriums or restrictions

• Reviewing easements and property boundaries

Infrastructure Assessment

• Verifying utility capacity (water, sewer, electrical, telecom)

• Ensuring adequate fire protection and emergency access

• Evaluating road capacity for increased traffic

Site Conditions Analysis

• Geotechnical soil testing to determine foundation requirements

• Environmental testing for contamination

• Surveying for boundaries, elevations, and topography

Key Players: Surveyors, geotechnical engineers, environmental consultants, real estate attorneys

Property Manager Insight: Pay attention to utility capacity and public transit access during this phase—these factors will directly impact your building's long-term appeal and operational costs.

Phase 2: Design & Engineering

Duration: 4-8 months

This is where your building takes shape on paper before any dirt is moved. The design phase requires coordination among multiple specialists:

The Design Team

• Architects create the overall building concept, balancing aesthetics with functionality

• Structural Engineers design the "bones"—calculating steel/concrete framework to safely carry all loads

• Mechanical Engineers plan HVAC and plumbing systems for comfort and functionality

• Electrical Engineers design power distribution, lighting, and fire alarm systems

• Civil Engineers handle site elements like drainage, parking, and utility connections

Key Deliverables

• Complete construction documents (architectural and engineering drawings)

• Material specifications and building code compliance verification

• 3D building models to detect potential conflicts before construction

Property Manager Insight: This is your moment to influence building functionality. Advocate for adequate storage, accessible mechanical rooms, proper HVAC zoning, and maintenance-friendly designs.

Phase 3: Permitting & Pre-Construction

Duration: 2-4 months

Before breaking ground, the project must navigate approvals and assemble the construction team.

Major Activities

• Permit Applications: Submitting plans to building departments for code compliance review

• Insurance & Legal Prep: Securing builder's risk and liability insurance

• Contractor Selection: Bidding process to select general contractor and major subcontractors

• Construction Planning: Site logistics, safety protocols, material procurement, and scheduling

Property Manager Insight: Review mechanical and electrical specifications during this phase to understand what maintenance requirements you'll inherit.

Phase 4: Site Preparation & Earthwork

Duration: 2-4 weeks

The transformation begins as raw land becomes a construction site.

Key Activities

• Site Setup: Temporary offices, fencing, utilities, and material storage

• Clearing & Grading: Removing vegetation and creating level building pad

• Utility Installation: Bringing water, sewer, electrical, and telecom to the building footprint

• Excavation: Digging foundations and installing underslab utilities

• Drainage Systems: Installing proper site drainage to protect the future building

Primary Trades: Heavy equipment operators, utility installers, surveyors, construction laborers

Phase 5: Foundation & Structure

Duration: 4-12 weeks depending on building size

The building's permanent construction begins with its foundation and structural frame.

Foundation Work

• Concrete footings and foundation walls poured to transfer building loads safely into the ground

• Reinforcing steel placement and utility sleeves installed

• Waterproofing and drainage systems around foundation perimeter

Structural Frame

• Steel Frame Buildings: Cranes lift prefabricated steel columns and beams into place, with ironworkers bolting/welding connections

• Concrete Buildings: Crews set formwork, place reinforcement, and pour concrete floor by floor

• Progress is visible daily as the building rises to its full height

Primary Trades: Ironworkers, carpenters, concrete finishers, crane operators

Property Manager Insight: The structural choices made here affect your building's flexibility for future tenant improvements and system upgrades.

Phase 6: Building Envelope

Duration: 6-10 weeks

The goal is to "dry in" the building—creating a weatherproof shell so interior work can proceed safely.

Major Components

• Roofing: Installation of roof structure, insulation, and weatherproof membrane

• Exterior Walls: Framing, insulation, waterproofing, and final cladding (brick, metal panels, glass curtain wall)

• Windows & Doors: High-performance glazing systems and entrance installations

• Weatherproofing: Sealing all joints and penetrations against water infiltration

Primary Trades: Roofers, glaziers, masons, waterproofing specialists, facade installers

Phase 7: MEP Systems Installation

Duration: 8-12 weeks

The building's life support systems are installed - mechanical, electrical, and plumbing (MEP) that make the space functional.

System Installation

• HVAC: Rooftop units, ductwork distribution, controls, and air handling equipment

• Plumbing: Water supply, drainage, and fire sprinkler systems throughout the building

• Electrical: Power distribution, lighting, elevators, and backup systems

• Low-Voltage: Data cabling, security systems, fire alarms, and building automation

Critical Timing: Much of this "rough-in" work happens before walls are closed, making coordination essential.

Primary Trades: Licensed electricians, plumbers, HVAC technicians, sprinkler fitters, elevator installers

Property Manager Insight: These systems represent 15-20% of total construction costs and will be your primary maintenance responsibility. Understanding their layout and specifications is crucial for efficient operations.

Phase 8: Interior Build-Out

Duration: 6-10 weeks

The building transforms from structural shell to finished office space.

Key Activities

• Interior Framing: Non-structural walls creating offices, conference rooms, and common areas

• Drywall & Ceilings: Wall finishing and suspended ceiling installation

• Flooring: Carpet, tile, hardwood, or other finish materials per design

• Millwork & Fixtures: Doors, cabinetry, bathroom fixtures, and built-in elements

• Final MEP Trim-Out: Light fixtures, outlets, thermostats, and sprinkler heads

• Painting & Finishes: Final color schemes and decorative elements

Primary Trades: Drywall installers, painters, carpenters, flooring specialists, fixture installers

Phase 9: Commissioning & Inspections

Duration: 2-4 weeks

Quality control and regulatory approval ensure the building is safe and operational.

Critical Steps

• Punch List: Detailed walkthrough identifying any incomplete or defective work

• Systems Testing: Comprehensive testing of HVAC, electrical, plumbing, elevators, and life safety systems

• Government Inspections: Building and fire department officials verify code compliance

• Certificate of Occupancy: Official approval allowing legal occupancy

Property Manager Insight: Request comprehensive commissioning reports and as-built drawings during handover—these documents are invaluable for future maintenance and troubleshooting.

Phase 10: Handover & Occupancy

Duration: 2-4 weeks

The building transitions from construction project to operational asset.

Final Steps

• Documentation Transfer: As-built drawings, equipment manuals, warranties, and maintenance schedules

• Staff Training: Facilities team education on building systems operation
