Scope Of Work

Description:               

This project involved the demolition of the existing CHP, Building 86, two storage sheds (numbers 121 and 122), and two existing fuel oil storage tanks and the construction of a new CHP at Defense Depot Susquehanna Pennsylvania.  The new CHP is designed to have two 75 MBTU/hr boilers and one 50 MBTU/hr boiler, with Number 2 diesel fuel as primary fuel. The design includes administrative space, a storage tank to hold a minimum of 30 days’ supply of Number 2 diesel fuel, emergency backup generator, security fencing, access gate, and fuel tanks. Anti-terrorism/Force Protection measures include traffic control barriers.

Scope of Services Provided: 

Field Quality Control and Special Inspection Services included that of foundation soil bearing, structural fill, utility backfill, reinforcing steel, structural cast-in-place concrete (including grade beams, pile caps, slabs-on-grade), structural masonry mortar and grout (for CMU foundation walls), stone sub-base, hot-mix asphalt, precast concrete panel connections, structural steel connections, metal decking connections, and spray-applied fireproofing.  The foundation system consisted of caissons and spread foundations bearing on rock layers.  To ensure the concrete shafts had proper bearing capacity, Specialized Engineering provided down-hole inspections of caisson excavations.

Laboratory Testing & Analysis Services included that of proposed fill materials, cast-in-place concrete cylinders, CMU mortar and grout samples, hot-mix asphalt, and fireproofing density samples.

Consulting Engineering Services included providing numerous recommendations during the construction of the project.  During caisson construction, Professional Geologists from Specialized Engineering were able to minimize the costs of over excavation of rock that was suitable for the support of the foundations.  Concrete placement techniques were reviewed and efficient strategy recommendations were presented that saved the Owner from costly processes and the Client/Contractor from schedule delays.

Regulatory Requirements:

Specialized Engineering was also responsible for ensuring that the project was built in accordance with the quality standards defined in the project plans, specifications and the U.S. Army Corps of Engineers.
