Office Mezzanine Engineering Plans -- 2

I'm looking for an engineer to design plans for a building mezzanine that will be used as office space. The plans need to be stamped by a professional engineer and accepted by the state of North Dakota and The City of Williston Building department.

Key Features:
- The mezzanine will need to have partitions for separate rooms.
- The design should ensure that the mezzanine can be accessed via an extension off the current mezzanine using the existing staircase.
- The design must consider the load bearing capacity to ensure safety and compliance with building codes.

Ideal Skills and Experience:
- Professional engineering degree and credentialing
- Extensive experience with commercial building design
- Knowledge of North Dakota and City of Williston building standards
- Ability to create plans with necessary details for construction

I will provide pictures and details regarding the existing structure.
