RE: Proposed Modifications to Existing Structural Elements
Project Location: 235 Logan Pkwy. NE, Fridley, MN 55432
Project No. 22-6172
Dear Mr. Nelsen:
This letter is being sent to discuss the proposed revisions to the existing house at the above address as
related to: the proposed removal of wall between kitchen and dining room along with the infilling the
existing stairway and providing a new stairway in a different location. The inspection and report were
completed by Steve Eiker, P.E.
The scope work includes the following:
1. An interview of you regarding a history of the property and performance of the structure
2. Requesting from you any other information relevant to the evaluation of the structure
3. Visual observations during a physical walk-through on April 18, 2022.
4. Observe factors influencing the performance of the structure
5. Provide a written report containing the following:
a. Scope of services
b. Observations, site characteristics, and data deemed pertinent by me
c. Discussion of major factors influencing structural performance and rationale in reaching
conclusions concerning the subject residence
d. Preliminary conclusions regarding feasibility of proposed renovations or structural
modification.
e. Final engineered design is not included.
6. This inspection is limited to: An assessment of the structural characteristics of the existing wood
stud wall and the main floor framing to be modified/removed and the nearby, or related, structural
elements as determined by the engineer.
7. Please note that this assessment is considered preliminary due to concealed conditions and
should be verified after the removal of surface materials and final architectural plans are
submitted.
SUMMARY
In my professional opinion, the wall between the kitchen and dining room is a primary load-bearing wall. It
may be removed, or portions may be removed with added structural support.
The new opening(s)will need to be supported with a header or structural post and beam system such as
a laminated veneer lumber (LVL) beam structural system. The exact size of the beam can be designed
should you decide to proceed. Refer to the Recommendations section of this letter for further information.
In my professional opinion, the proposed floor infill of the existing stairs and the proposed new location of
the stairs is structurally possible with some new framing to accomplish those tasks.

This conclusion is preliminary and is based on visible evidence at time of inspection and should be
verified once framing is exposed and a final remodel plan is decided on.
INSPECTION DETAILS
• Our client, to whom this report is addressed, is the homeowner.
• The client was present during our site visit.
• The following areas were inaccessible or not visible, and this limited the extent of our structural
inspection:
o Portions of the attic area
o Most of the foundation system and slab (underground and/or concealed due to finished
conditions)
o Wall and floor framing (concealed)
DESCRIPTION OF STRUCTURE
• This building is a one-story single-family home.
• The house has a full basement.
• The structure was constructed in 1954 with an addition in 2002.
• The front of the house faces south.
DOCUMENT REVIEW
No documents were provided.
SITE OBSERVATIONS
An opening or openings are planned between the existing kitchen and dining room. The proposed spans
are to be determined at a later date. The width of the uniformly distributed load from the roof framing
(tributary width) is approximately 14 feet.
The basement evaluation is limited to the area related to the modification above. The first-floor joists in
the corresponding area of the basement are supported by a wood beam and an interior wall in good
condition. The first-floor joists in that same area of the basement are in good condition.
The attic space is in good structural condition. There is no flooring in place. The roof rafters and attic floor
joists are in good condition.
RECOMMENDATIONS
The interior wall between the kitchen and dining room may be removed. The opening(s)will need to be
supported with a header or structural post and beam system such as a 2.0E Microllam, or equivalent,
laminated veneer lumber(LVL) beam structural system. The size of the headers or beams can be
determined when the final locations of proposed openings are decided. A general rule of thumb for beam
depth is approximately 1 inch of beam depth for each foot of beam span. This is only an estimate. Actual
designed sizes will vary.
Creating a new stair opening in the main floor will involve some new beams to header off the existing
joists (to create the opening in the floor) and either posts or a wood stud wall for bearing. The posts or
bearing wall will require new concrete footings to be poured.
Please note that this assessment is considered preliminary. When proposed plans are determined, final
beam and post sizes can be designed.

Compared with similar size sections, the Microllam LVL beams that I am recommending can support
heavier loads and allow greater spans than conventional lumber. Failure to follow good procedures for
storage, handling and installation could result in unsatisfactory performance and unsafe structures.
Generally, the schedule of work will include the construction of temporary support wall for the removal of
existing framing, installation the beam and posts, and removal of the temporary support.
If a different product or project layout is proposed, please contact me for additional information. Criterium-
Schimnowski Engineers is available to provide the engineered design for the support beam should you
decide to proceed.
DESCRIPTION OF TERMS
Terms used in this report to describe the condition of observable components and systems are listed and
defined below. It should be noted that a term applied to an overall system does not preclude that a part or
a section of the system or component may be in different condition:
Excellent- Component or system is in "as new" condition, requiring no rehabilitation, and should
perform in full accordance with expected performance.
Good- Component or system is sound and performing its function. Although it may show signs of
normal wear and tear, some minor rehabilitation work may be required.
Fair- Component or system falls into one or more of the following categories: a) Evidence of
previous repairs not in compliance with commonly accepted standards, b) Workmanship not
in compliance with commonly accepted standards, c) Component or system is obsolete, d)
Component or system approaching end of expected performance. Repair or replacement is
required to prevent further deterioration or to prolong expected life.
Poor- Component or system has either failed or cannot be relied upon to continue performing its
original function as a result of having exceeded its expected performance, excessive
deferred maintenance, or state of disrepair. Present condition could contribute or cause the
deterioration of other adjoining elements or systems. Repair or replacement is required.
SCOPE OF SERVICES and LIMITATIONS
The purpose of this inspection and report/design is to evaluate the current condition of the structural
system of this building as related to the proposed modifications, revisions, or repairs. The report is not to
be considered a guarantee of condition and no warranty is implied.
Our evaluation of this structure is based on many indirect observations. Examination of the foundation is
completed without excavation; therefore, we cannot be certain of the condition below grade. Additionally,
we cannot certify that the footings extend below the frost line. We cannot see most of the framing. We
look for cracks, bulges, and other evidence of distress or deterioration to help us evaluate the condition.
In addition, often, construction details cannot be known, and we then assess that system with typical
construction practices for our area in mind. As with any limited inspection, it is possible that there are
structural deficiencies that cannot be known. In addition, it is possible that a final structural analysis and,
therefore the design details, will require exposure of concealed conditions (i.e. removal of drywall).
This scope of this inspection does not include a comprehensive evaluation for code compliance,
governmental regulation compliance, fire safety, or hazardous materials in or around this building. It does
not include an inspection of heating, cooling, plumbing and electrical systems or repair designs.
Inspecting for mold is not included in the scope of a structural inspection. Our services do not include
determining the presence of a virus in this building. Evidence of any moisture-related problems in the

home is not always visible. We cannot be responsible for any such conditions that might be discovered
later. This report is not a termite inspection, and no responsibility is assumed for any damage caused by
wood-destroying organisms.
This report/design is based on an examination of the structural system and is an opinion about the
condition of the structural system of the building. It is based on evidence available during a diligent
inspection of all reasonably accessible areas. No surface materials were removed, no destructive testing
undertaken, nor furnishings moved. This report is not an exhaustive technical evaluation.
As Professional Engineers, it is our responsibility to evaluate available evidence relevant to the purpose
of this inspection. We are not, however, responsible for conditions that could not be seen or were not
within the scope of our service at the time of the inspection.
