Preconstruction Services


Petra’s ability to ensure a successful project begins at the earliest stage. During preconstruction, we focus on assessing every aspect of a project, from materials and labor, to equipment, subcontractors, permits, and more. Our experienced team works to provide reliable cost estimates of what it will take to complete a project at every stage of design (conceptual, schematic, design development, and construction documents).

In collaboration with key stakeholders, our preconstruction team works to establish accurate and realistic pricing, ensure the budget and design align with owner expectations, avoid double-ups or gaps, analyze system selections, determine the most probable escalation factors for the intended start date, clearly define the scopes of work related to the cost, continually track all cost change throughout the design process, and develop a logistics plan and schedule.
