Let the mission define the security boundary
This planning example concerns a diplomatic property near Embassy Row. Public reception, staff circulation, and restricted offices may need different access rules, but those zones should come from the mission’s security lead. A generic commercial master-key diagram cannot establish the appropriate arrangement.
Agree who may authorize the survey, what information may be recorded, and how it will be shared. Do not send sensitive floor plans, credential records, or restricted-area photographs through an ordinary quote form. The mission should specify its approved communication and contractor-screening process.
Survey the doors before selecting cylinders
Record the existing lock case, door and frame condition, dimensions, handing, and any required listing or finish. Retaining a decorative outside plate may be possible for some assemblies; it cannot be promised without checking the concealed hardware and the proposed replacement.
If the property is designated historic, check the proposed exterior work with the DC Historic Preservation Office. Preserving an appearance and obtaining the necessary approval are separate tasks.
Build key control around authorization
Specify who may order duplicate keys, approve a new access group, retrieve departed staff credentials, and request a cylinder change. Restricted key products have different contractual and technical controls. Ask for the actual duplication policy rather than assuming any key labeled high security cannot be copied.
Federal PIV requirements do not automatically apply to every diplomatic building. Where an authorized project calls for PIV credentials, NIST SP 800-116 Rev. 1 provides a risk-based facility-access reference. The responsible security authority must determine the applicable requirements.
For an inquiry, use the embassy security page to describe the non-sensitive scope. Confirm the required qualifications and approvals directly before arranging access.
