Nature of Firm’s Responsibilities on the Project:

The YMCA project involved the construction of a new YMCA facility located in Upper Hanover Township, Montgomery County on approximately 48 acres. The facility includes indoor recreational facilities, administrative and program space in a newly constructed building, outdoor swimming pools, walking trails, parking, service facilities and stormwater management BMPs.  Engineering services for the project included: land planning, feasibility studies, stormwater management, E&S control, on and off site utilities, NPDES permitting for stormwater discharge, PennDOT permitting for frontage improvements plus offsite road intersection upgrades, municipal land development approvals, and landscape architectural services for site plantings and lighting. Additionally, Horizon Engineering coordinated the services of traffic engineers, wetlands consultants and soils scientists.

Land surveying services included: boundary, topographic & location survey, off-site water and sanitary sewer route survey, road cross-section survey, and location of delineated wetlands and soils infiltration testing. During construction Horizon Engineering performed additional survey for building and stormwater stakeout as well as full site as-built survey. Horizon Engineering also performed construction observation, review and approval of contractor payment requests, NPDES permit compliance inspections, and trouble-shooting and field issue resolution management.

Unique Design Features:

• Extensive collection of stormwater Best Management Practices (BMP’s) to achieve NPDES permitting
• 1/3 mile off-site water and sewer main extension including tunnel boring under John Fries Highway
