Our Partners

Strong communities are formed through alignment with those individuals and organizations that are fully engaged in working toward a tomorrow that is inclusive, collaborative and kind to the environment and each other. Real change materializes when hard work meets great solutions focused on continued excellence. McMac Cx is proud to be able to say we are aligned with the following partners

A complex project can be costly and time consuming

Autocase can help with that

Resiliency and sustainability cost more in the short run but climate change and engaged citizens demand longer-term value-based decision making. Triple Bottom Line value ensures community, environmental and financial concerns are addressed. Autocase provides the Triple Bottom Line Cost Benefit Analysis (TBL-CBA) balance to plan and design high performing buildings and resilient and sustainable sites.

Autocase for Sites

Resilient city design starts with effective stormwater management. Autocase for Sites calculates the benefits & costs of best management practices that can clean stormwater, reduce flooding, clean the air, and more.


Autocase for Buildings

Cities planning high performing building projects or pursuing LEED certification need to make the business case. Autocase for Buildings compares the benefits and costs to the environment, community, and occupants of building designs.
