FRIDLEY, MINNESOTA
REPORTED TO: Mr. Daniel J. Murphy FURNISHED BY:
5600 Regis Drive COPIES TO,kk- "_Building Inspection .Dept..
Fridley, Minnesota 55421 Village of Fridley
LABORATORY No. 9-3004
GENERAL
We were recently requested by Mr. Daniel Murphy of the above address to examine the foundation
walls and other load bearing construction at this project. Our client intends to
enclose a portion of an existing porch to enlarge the useable living quarters. We.
understand the local building inspector requires professional examinations in such instances s
for verification of structural adequacy prior to issuing a building permit.
a
The building is an 8 year old rambler -type home with a full basement and attached 1% car
garage. The house is positioned high on the west edge of a hill. To establish a level
grade for the structure during the initial construction, it was necessary to place
several cubic yards of compacted earth fill materials along the rear of the home. The
yard is presently terraced to accommodate a more than 30' high natural -artificial embankment.
The structure faces the east, with the garage positioned on the south end. Directly behind
the garage is an 8' x 14' porch area connected to the kitchen of the home. The garage
floor is at main floor level and is supported by fill material and natural soils., The,
porch floor is'a structural unit positioned at main floor level and supported on three,
sides by a portion of the south basement wall, the west garage foundation wall and an
extension of the south garage foundation wall. The kitchen is positioned over a portion
of the basement and, consequently, has a wood frame floor.
The porch floor consists of a 5" thick reinforced concrete slab with thickened edge.support
Reams cast into the member. The underside of the slab is exposed from.the open west side.
Wooden posts bear on the top of the slab around the perimeter which support a portion of
the main gable roof. Apart from this construction, nothing else bears on the porch floor
besides light furniture.
All foundation wall construction is 12" concrete masonry block placed in a running bond
pattern. The supporting walls for the porch,slab extend 10' above the existing exterior
grade and are surfaced with a smooth stucco material.
INVESTIGATION
On October 2, 1970, we performed a visual investigation at the project. Of particular
concern in our examination were the south and -west basement walls, the walls supporting
the concrete porch floor, the garage floor construction and the porch itself.
The south basement wall was cracked vertically at a point corresponding to the junction with
the west garage foundation wall. The basement floor was cracked at the extreme southwest
corner. The cracking of the basement floor and condition of the south basement wall indicated
that a slight movement of this construction had occurred.to the southwest. The cracking
was judged by us to be quite old, considering the condition of the fractured edges.
This compares favorably with information received from the owner maintaining that this
cracking is approximately 7 years old.

con
We observed some step cracking in the west basement wall, indicating that a slight
amount of_movement of this construction had occurred toward the south. The configuration
of the cracking did not suggest that any differential settlement of this construction.
had occurred. The west basement.wall was cr eked beneath door and window lintels.at the
lint -el bearing points, indicating that the b ockwork had undergone excessive flexural
stresses under the high.concentrated loads. JJ
The two east -west .masonry walls supporting the porch were neither cracked nor noticeably
bowing during our inspection. The north portion of these two walls did not display any
visual indication of rotation or displacement, although examination of the adjoining
basement construction had indicated that slight movement had, in fact, occurred. The
south portion of the two east -west walls hadlrotated.slightly, opening away from the
south foundation wall of the garage toward.lthe west and in a southerly direction.
Examination revealed that the structural int grity of the porch -wall junctions for these
two east -west walls had been maintained, despite any movements which had occurred in
the composite construction.
The north -south masonry wall upon which the,�east edge of the porch and the west wall of
the garage rested was also intact with no cracking observed in the stucco. However,
this wall was noticeably bowed in the.north-south direction, indicating that the
backfill soils supporting the garage floor slab were exerting significant lateral
pressure against it. This bowing of the wail had caused a slight movement.of the concrete
porch slab in a westerly direction. The garage floor was examined and found to have
settled along the west.foundation wall. Th s settlement resulted in a dishing configuration
in the s lab , with a maximum settle----- f a , most . 21t near a doorway in the west wall.
The wall had also pulled away from the garage floor slab, leaving a crack at the junction
{ of the two construction elements.
CONCLUSIONS AND REMARKS
4.
Although we are aware that a considerable fount of,fill material had been placed along
the westerly construction at the project, d we in no way merit that the work was
performed in a well engineered and.conscien4ous.manner, we must conclude that no
excessive foundation settlement other than. ossibly a small amount at the extreme west
i! end of the south east -west porch support wall has occurred`. Settlement of a structure
due to weak soil consolidation generally increases with time; therefore, this may never
be a problem at the project, as the construction has already existed for a substantial
period. However, erosion of the steep bank behind the structure or material slippage
due to moisture saturation of the soils could conceivably cause difficulties with the
structure at a later date. Intelligent observance of conditions in this area, together.
with maintenance of a sod or shrubbery covering of the slopes, will minimize the
possibility of future difficulties.
I
Should any marked changes occur in the structure, professional assistance should be
directly sought.

Most of the cracking in the foundation.of the structure, as pointed out in our report,
can be traced to settlement activity in the garage floor area. Our observations indicate
that compaction of soil materials in the garage interior was poor, We understand from
the owner that a clay material was.placed there. This type material is difficult to
compact in small areas. Also, saturation of this type soil substantially reduces the
interparticle support capability of the material. The weight of the material, then,
transfers into the masonry block wall.with-very little of this load being assumed by the
soil itself.
Deflection.of the garage floor provides a drain along the critical west -wall for melt
water from an automobile parked in the garage, forcing more load against the wall. Masonry
block work is quite flexible in the lateral direction and bows under the Load as noted.
If the contact between the porch floor and supporting walls is. good, as,our inspection
indicates, then it will move with.the wall as we.suspect has happened at this home.
The step cracking below lintels suggests that the lintel bearing detail for this
construction was not completely successful. Plastic flow in the reinforced concrete
spanning construction was probably not accounted for in the end bearing conditions for the.
lintel. Since this type of interparticle flow or what is commonly referred to as "creep"
also reduces with time, it is feasible that 'the mortar construction in these areas --
can now be repaired and retain nearly complete integrity.
Concerning prospects for enclosing the area above the porch, we envision this intended
construction as not having any adverse structural affect on the existing structure and,
:"therefore, advise our client to proceed._ Consideration, however, should be given to
insulating the existing floor and the west garage wall for higher serviceability of
this proposed dining quarters.
We recommend that chipping and remort.aring of the masonry block work in the basement be
performed to reduce heat losses in -the structure and provide a monolithic condition for
better.transfer of the house service wall loads.
In order to prevent water from draining down the interior of the west foundation wall, the
garage floor slab should be either improved or replaced. Rubber sealant materials are now
available which will assist in waterproofing the improved or reconstructed ,joint between
the floor and wall construction. The most optimum method for correction here would be
removal of the floor slab, removal of undesirable backfill soils, placement of granular
well compacted fill materials in the garage.interior area, and reconstruction of the
garage floor, maintaining a definite grade to the main door to the east. Construction
warranty provisions and.available capital would have bearing on just how much correction
work could be attempted.

REGULAR COUNCIL MEETING OF NOVEMBER 16, 1970 PAGE 12
ON STREET PARKING IN LOCKE PARK:
Councilman Harris said that he was concerned about the on street
parking along Locke Park. He has indicated to the City Engineer
there should be some plans to post 69th Avenue so there is not parking
on the street, so the people would use the parking lot..:This would-be
a real problem if there are cars parked on both sides of the street.
The service road should also be posted.
RECEIVING THE MINUTES OF THE BOARD OF APPEALS MEETING OF NOVEMBER
10, 1970:
'A REQUEST FOR A VARIANCE OF SECTION 45.053, 4B, TO REDUCE THE SIDE
YARD REQUIREMENT FROM 10 FEET TO 9.6 FEET TO ALLOW THE CONSTRUCTION
OF AN ADDITION ONTO AN EXISTING DWELLING LOCATED ON LOT 3, BLOCK 4,
PARKVIEW OAKS 1ST ADDITION, THE SAME BEING 5600 REGIS DRIVE N.E.,
FRIDLEY, MINNESOTA. (REQUEST BY MR. DANIEL MURPHY, 5600 REGIS
DRIVE N.E., FRIDLEY, MINNESOTA):
The City Engineer said that this request by Mr. Daniel Murphy is for a
variance from 10 feet to 9.6 feet to allow construction of an addition
to his house. The Board of Appeals recommended approval. There are
some cracks along the foundation and the Building Inspection Department
suggested that Twin City Testing check them out. They took soil borings
and found that the structure was sound but suggested that the cracks
be bonded and the owner has been notified of this.
MOTION by Councilman Harris to concur with the Board of Appeals and
grant the variance to Mr. Daniel Murphy subject to the stipulations of
the Board of Appeals, and receive their Minutes. Seconded by Councilman
Sheridan. Upon a voice vote, all voting aye, Mayor Kirkham declared the
motion carried unanimously.
CONSIDERATION OF DATA PROCESSING NEEDS AND PURCHASE OF NCR 400:
The Acting City Manager said that at present they are renting a machine
on a monthly basis, with no commitment. The proposal is to enter into
a 3 year lease which would save.approximately $140 per month. He felt
that they would be keeping the machine for the next three years. The,
City would pay out in 28 months under the present arrangement the same
as if they were leasing for 3 years. There is a full maintenance
agreement on the machine. Councilman Breider asked if at the end of
three years, the.price could jump on the maintenance agreement. The
Representative said that it would not go up appreciably. Councilman
Breider asked if the maintenance contract covered everything. The
.Representative from NCR said that it would cover everything to keep the
machine in running condition.
MOTION by Councilman Harris to concur with the'Administration and enter
.into a three year lease agreement for NCR 400. Seconded by Councilman
Liebl. Upon a voice vote, all voting aye, Mayor Kirkham declared the
motion carried unanimously.

THE SAME BEING 5600 REGIS DRIVE N.E., FRIDLEY, MINNESOTA. (REQUEST BY MR. DANIEL
HY, 5600 REGIS DRIVE N.E., FRIDLEY, MINNESOTA.)
Mr. Dave Dahl, representing Sussel Company, presented the request.
Plans of the proposed addition, a survey of the lot and pictures of the existing
dwelling were shown to the Board.
Mr. Dahl explained the variance is needed to enclose an existing deck which will
be turned into living area. The present structure is 9.6 feet from the lot line
and the proposed work will be in line with what is already existing.
The pictures of the dwelling showed there were two cracks in the foundation.
Chairman Minish asked Mr. Bagstad for a report on the foundation.
Mr. Bagstad stated there had been some concern about the settling of the
foundation and the Building Inspection Department had asked the owner to have
soil tests taken. The investigation was done by Twin City Testing and according
to their report the structure is sound. The report stated the cracking is
approximately 7 years old and the structure has settled about all that it will.
Twin City Testing did suggest that the cracks be bonded and the owner has been
notified of this.
MOTION by Drigans to receive the report from Twin City Testing.
Seconded by Ahonen. Upon a voice vote, there being no nays, the motion carried
unanimously.
MOTION by Ahonen to close the public hearing.
Seconded by Sondheimer. Upon a voice vote, there being no nays, the motion
carried unanimously.
MOTION by Ahonen to recommend to the City Council approval of the request for
the following reasons:
1. They will be maintaining present building lines.
2. There were no objections from adjoining property owners.
3, Recommend the Building Inspection Department take note of the suggestions
made by Twin City Testing when they issue the building permit.
