Abstract
Level access structures including a first module and a second module. The first module includes first sidewalls defining a first open shaft with a first top end and a first bottom end opposite the first top end. The second module includes second sidewalls defining a second open shaft with a second top end and a second bottom end opposite the second top end. The second module is complementarily configured with the first level access module. The second module is configured to selectively couple to the first module with the second open shaft aligned with the first open shaft to define a continuous open shaft. The continuous open shaft is configured to contain a level access system.
