CONSTRUCTION SERVICES
A well-planned project helps the design and construction team develop practical and efficient services. GER’s experience provides relevant guidance and construction management. GER’s experience includes construction documents; cost analyses for budget development; construction contract administration; construction bidding, plans and specifications; bid evaluation and qualification of contractors; surveying; construction quality assurance and oversight representation; ordinance and code consultation; and site and plan reviews.
Site Development:
Principal Engineer for new shooting range site development and design on 11-acre site. Services included: preliminary design; meetings to refine MSHP needs; preliminary site layouts to maximize site use while minimizing total construction cost; construction and budget review. GER coordinated Surveying, Architectural, Structural, Mechanical, Electrical, Plumbing sub-consultants, conducted a pre-design geotechnical engineering investigation to support civil and structural design, and designed the site layout, grading, utilities, and stormwater management systems.
Wastewater:
Performed preliminary evaluation of potential wastewater systems, followed by engineering design for an onsite, no-discharge wastewater treatment system for Our Lady Help of Christians Catholic Church. GER completed permit applications and construction plans for the system according to MDNR criteria because the maximum daily flow could potentially exceed 3,000 gallons per day at their semiannual special events. Designed an Onsite Wastewater Treatment System (OWTS) for a single-family residence in Callaway County with a design flow of 360 gallons per day. The site soil evaluation showed the soils would require an engineered alternative treatment system. GER designed a no-discharge treatment system utilizing subsurface drip irrigation, prepared permits for the Callaway County Health Department, and completed the construction plans for the homeowner’s contractor.
Bridge Design:
Retained by client to provide design services and construction oversight for the replacement of a failed haulroad crossing with a CON/SPAN precast concrete bridge capable of supporting loads of up to 100 tons in Randolph County, Missouri. Bridge serves as main artery for the haulage of coal combustion residue to a permitted waste disposal facility.
