Appearing in today's Federal Register is a request for public comment on an intended Interpretive Bulletin (IB) for Model Installation Standards Foundation Requirements in Freezing Temperature Areas Under 24 CFR 285.312(b)

Comments are due by August 21st, 2017.

A summary of key findings from the engineering assessment include:

  • “… reviewed FFF designs contained a number of flaws or non- conformances, including:

o   A lack of clarity of technical requirements in manufacturer installation instructions, details, and notes;

o   Missing or vague criteria for identification and measurement of soil frost susceptibility;

o   Missing or vague guidance for determining soil moisture, sub-surface drainage conditions, and water table depth in relation to determining if the site is ‘‘well drained’’ and suitable for an FFF installation; and

o   Missing guidance to direct appropriate site specific adjustments of important installation details (e.g., depth of non-frost-susceptible soil or fill layers and lay-out of sub-surface drainage when required).
