Ground-up construction of a new building carries risk that is distinct from the risk of owning
a completed, income-producing property. The [[narrow-bank-financial-model|Narrow Banking Model]] removes
construction-period debt risk by funding construction with equity, but construction itself
remains subject to cost, schedule, and regulatory uncertainty that no financing structure can
eliminate.

## Cost overruns

Construction budgets are estimates prepared in advance of the work being performed, based on
materials pricing, labor availability, and site conditions known at the time the estimate is
prepared. Actual construction costs can exceed budgeted costs for reasons including materials
price inflation, labor shortages, unforeseen site conditions, and changes to the scope or
specification of the building during construction. A material cost overrun can require
additional equity capital to complete a project, reduce the return available on the completed
asset relative to the return assumed at the outset, or, in a severe case, affect the
feasibility of completing the project as originally scoped.

## Delays

Construction schedules can be extended by weather, materials or equipment delivery delays,
labor availability, contractor performance issues, and permitting or inspection delays. A
delayed project generates no rental income during the extension while continuing to incur
holding costs. Because the Narrow Banking Model's debt phase begins only once a building is
completed and stabilized, a construction delay also postpones the point at which the
[[debt-service-and-financing-structure|debt phase]] and any associated First Secured Mortgage Debenture issuance can begin.

## Contractor risk

Construction is performed by third-party general contractors and subcontractors under
construction agreements. Contractor performance risk includes the possibility that a
contractor becomes insolvent, fails to perform to specification, or is otherwise unable to
complete its contracted scope of work. Contractor risk is managed through contractor selection,
contract terms, and construction oversight, but it cannot be eliminated: a contractor's
financial condition and performance capability are outside the direct control of the investment
vehicle.

## Zoning and permitting risk

A development site must obtain the zoning classification, building permits, and regulatory
approvals required under the applicable municipal, provincial or state, and national regulatory
framework before and during construction. Zoning and permitting processes can be lengthy,
subject to public consultation, and subject to conditions that are not known with certainty at
the time a site is acquired. A zoning or permitting delay, a permitting condition that requires
a change to the building's design, or the outright denial of an approval required to proceed
can delay a project, increase its cost, or, in a severe case, prevent a specific site from being
developed as planned.

## Pre-leasing and lease-up risk

The Narrow Banking Model does not require pre-leasing before construction begins — buildings
are constructed on an unlevered basis without a pre-leasing condition. This removes pre-leasing
as a condition of starting construction, but it does not remove leasing risk from the project:
a completed building must still be leased to generate income, and the pace and terms of that
lease-up are subject to the [[market-and-property-risk|market and property risk]] applicable to the specific location.
A building that takes longer than anticipated to lease, or that leases at rents below
underwriting assumptions, generates less income during the lease-up period than originally
projected, which in turn affects how quickly the property's [[interest-coverage-ratio|Interest Coverage Ratio]]
reaches the level required to begin the debt phase.
