5.6.1 Foundation Conditions. Describe foundation conditions, the type of foundation to be
used, the methodology used to determine bearing values and the maximum load bearing capacity
of the foundation. Indicate the maximum dead load and live load soil capacities and the ground
water level. In addition, for retaining wall design, indicate the allowable passive and active soil
pressures and the coefficient of friction.
5.6.2 Type of Construction. Briefly describe the available systems and conduct an economic
analysis to support the selection of the system chosen. Completely describe the system chosen.
220.127.116.11 Special Features. Describe all special or unusual features to be included in the structure
which are not evident from a definitive drawing.
5.6.3 Structural Floor and Roof System. Describe the structural floor and roof systems
proposed. Provide length and spacing ofprincipal members, if different from standard building
5.6.4 Lateral Forces. Describe the structural system proposed to resist lateral forces of the
structure and interior contents (e.g., attached mechanical and electrical equipment, interior walls,
etc). Indicate the seismic zone and wind velocity on which the design is based.
5.6.5 Live Loads. Identify the live load to be accommodated. Include floor and roof loads,
wind and earthquake, and other special loads, as applicable, with data justifying their use.
5.6.6 Special Considerations. Identify all unusual or special conditions that have been
accounted for in the design.
5.7.1 Heating, Ventilating and Air Conditioning (HVAC). Design HVAC systems in
accordance with MIL-HDBK-1190 and DM 3.03, unless otherwise specified by the "Scope" or
by a written waiver from the Contracting Officer. Outdoor design conditions shall be in
accordance with Tri-Service weather datamanual, NAVFAC P-89, Engineering Weather Data.
Use life cycle costing to evaluate the various HVAC system alternatives and configurations. In
the evaluation, include applicable design factors such as siting, orientation, insulation
alternatives, reflective surfaces, solar shading, fenestration glazing types, natural ventilation,
equipment efficiencies, etc.
A registered professional mechanical engineer shall be responsible for (i.e., supervise) the design
of steam supply and condensate, high-temperature water, chilled water, gas, compressed air and
fuel oil systems outside of the building or facility.
18.104.22.168 Heating. Indicate the indoor and outdoor design temperatures on which the design is
based and include calculations of the "U" factors for building roofs, walls, ceilings and floors.
Also describe the type of heating system, including the system components; the heating medium;
the method of air circulation and the type of terminal unit; the type of temperature control
system to be used, such as electric, pneumatic and electronic.
