The Triple+ Constraint in Stone Restoration: Time, Scope, & Cost
Fully understanding all the limitations to manage the quality of stone restoration work

The restoration of historic stone poses many challenges. It is critical to correctly identify the original stone and quarry to determine if it is still available from active quarries or salvage. Understanding the nature of the original stone characteristics and the underlying cause of failure is a critical next step. Identifying past and present causes of failures and past interventions will help determine which potential options are feasible. The choice to perform in-kind repairs such as replacement or dutchmen, patching, or more exotic treatments is determined by many variables, including the most fundamental three project constraints: time, scope, and cost.

Aeon Preservation Services will take you through the process of evaluating your mission, discuss current stone limitations, and help you map out key considerations for your next stone project.

Presentation topics will include:

  • Look at recent stone projects illustrating funding limitations, risk, difficult scope, and time constraints.
  • Discuss other constraints like the inherent vice in natural stone, product availability, new realities, and limitations on supplies and shipping.
  • Discuss how understanding stone project constraints may impact your approach.
  • Update on natural stone limitations and future forecasts.
  • The session includes a question-and-answer session for participants’ current projects.
