D'Appolonia prepares designs for potable and industrial water distribution systems and storm and sanitary sewer collection facilities for site development projects. We have developed specific designs to meet capacity requirements based on projected usage, applicable regulations and commercial and institutional design requirements. We have prepared permit applications, monitored system construction, and coordinated installations with governing agencies. Sewer system designs have included both pressure and gravity flow systems to tie into existing infrastructure. We generally subcontract the electrical, mechanical, and HVAC aspects of site development, and we have developed long-standing relationships with our engineering subcontractors. Many of our site development projects involve the design and construction of parking lots, parking garages, and site roadways. We design subbase and pavement systems and prepare plans and specifications for their construction. Our plans and specifications typically include features for controlling runoff consistent with the stormwater management plan and for mitigating adverse ground water impacts. We routinely provide monitoring services associated with construction of site infrastructure.
