A. Modular ~nc. 3400 Mountain View Dr. Anchorage, Alaska 99504 ~79-258! Attn: Jonas Arnbrister Subject: Lot 37, Track B, and Lot 48, Track A, Eagle Crest Subdivision dentlemen: Transmitted herein are the results of the subsurface investigation performed on the above property on April 23 and 24, 1974. Exploration consisted of two 15' test holes, drilled by Denali Drilling, inc., with a truck mounted mobile B-50 dr~.].l fitted with a hollow stem continuous flight auger. Disturbed ".samples were taken at 5' intervals either 1) by removing the sample from the flights of the auger near the bit (grab sampling) or 2) by means of a standard split spoon sampler advanced through the holl~ stem of the auger and driven into the soil.by the action of a 140 po~d pin-guided weight free falling 30". The blows required to advance the sampler ea~ 6" are recorded on the logs. The number of blows required to advance the sampler 12" is by definition the standard penetration. The test hole logs follow thc text. 1. Both test holes encountered silty sandy gravel of medium to high density to the depths explored. This material, in its natural undisturbed state, appears Lo be sufficlently dense to ~ccept the loading associated with modular home foundations. .2. The silty sandy gravel contains sufficient fines to preclude rapid transmission of free moisture. 3. There appears to be sufficient natural grade to the sites for general site drainage. J.A. ~.odular, Inc. ~4 ~ay 1, 1974 RECOM~LENDATIONS 1. Foundation system footings, shallow spread a. Minim~n width: 14", continuous; 18", isolated square. b. Minimum depth of cover (nearest horizontal grade to bottom of footing): 1. ~leated structure perimeter; 4' 2. Heated structure interior; 2' if bounded by grade slabs or tied, 3' if crawl space. Unheated structure top of footing at 5'. Footing at least 6" wider than ~tem. Reinforce stem and footing to resist tensile uplift forces along face of stem. Place 1" of styrofoam or similar non-water absorbing gas filled plastic rigid insulation below grade along the outboard face of perimeter footing walls to control heat loss so that the foundation soil will remain thawed, and to'provide a resilient component to absorb vertical and horizontal frost heave strains which would othe~ise act directly on the face of the footing. Nohe: sufficient heat excapemQnt into the crawl space to maintain the soil at above freezing temperatures is necessa~' to the foundation system for the "heated" structure. Bearing Value: 5,000 psf %.}here silty sandy gravels are the foundation soil, except in each case where the limits of Sections la and lb control. 2. Earthwork a. Remove.all loose fill, frozen soils and organic materials from below structures. Protect soils used for founding footings or grade slabs from freezing during construction as well as subsequent to construction. c. Protect soils from excess surface water and disturbance. d. Structural fill 1. · Materials; NFS sandy gra~e].s or gravelly sands arc satisfactory, the last 12" of fill, if any, below footings or slabs should have an'uppe~ size limit of about 2" while that, if any, b~low may include occasional cobbles. The lower limits of . . grain size is not more than 5% passing the ~00 screen. J. A. Modular, Inc. .~.ay 1, 1974 b. Backfill about footings 1. Where carrying grade slabs as in Section 2d2a. Exterior face of structure and unheated footings as in Section 2d2a, except the minimum permissible density shall be 88%, average 93%, and the top 12" of fill shall be an impermeable soll or paving to provlde, a seal against surface · water intrusion into the footing excavation. Natural soils; densification---if within 12" of the base of footings or grade slabs, densify top 6"+ as in Section 2d2, densification is to correct inevitable disturbance of the soil due to excavation, grading and miscellaneous construction operations. d. Excavation Only NFS soils are considered to be consistently easily incorporated into structural fill or for use as base, subbase, and frost protection soil for drives and parking areas. The remaining soils (silty soils) should be wasted or used in non-structural areas. 2. Trenches, composed of silty s~ndy gravels, where dry to damp should stand ~{ell. 3. Grading and drainage a. Surface Grade at 5% for ten feet away from structure, 2% elsewhere, direct surface water well a%.;ay from developed areas. b. Subsurface (for lot 37, Track B) Provide perimeter footing drains, these may consist of slotted light plastic conduit carried outboard of the footings. They should be placed on a layer, at least 3" thick, of p.c. concrete sand and surrounded wi~ well graded gravel (3/4" concrete gravel is satisfacotry). Place 3" of p.c. concrete sand over the gravel (purpose to avoid'migration of fines into the conduit, resulting in eventual clogging and loss of ground). The footing drain for Lot 37, Track B may be ter~inated at daylight downslope from the structure. J. A. ~odul~r, Inc. May 1, 1974 4. Paved areas a. Paving section (suggested section) 1. 2" surface course of bituminous concrete. 2" crushed base/leveling course, (the standard City of Anchorage or State specification for base course is suitable). e Frost protection 32" of NFS soil (may be native soil where applicable); total section 36", purpose to sufficiently control frost heave to allow pavement to carry traffic loads during spring tha~ without excessive chuckholing or other pavement failures. Transverse or longitudinal gradients on the order of 1.5+% w~ll discourage the formation of birdbaths during the thaw. ® If unpaved, a thicker layer of crushed base or well graded slightly silty sandy gravel should prove to be reasonably easy to maintain. The "frost protection" seqtion in areas of fill-is suggested ~orfu~ure upgrading to a paved section. Miscellaneous a. F~ost heave The shallo%~ fine grained soils are highly frost susceptible, and in the.unprotected state, frost penetration on the order of seven to nine feet is probable. Therefore, it is the writer's opinion that frost heave will prove significant. Care should be taken to cause surface water to drain away from the work in areas of cyclic freeze and thaw --- near entrances and about the perimeter of heated structures. (It is assumed that structures will have sufficient heat loss to maintain the bearing soils in the thawed state.) Unheated foundations remote from heated buildings will heave unless founded ~ell below the frost line, which is deepest in areas of snow removal or compaction. For typical areas the footing of Section lb3 is reasoDable, and should not develop significant heave even though it is imbedded within the ultimate frost zone. The use of permeable backfill ~nd surface seals avoids frost heave stresses from becoming large on the footing. J. A. Modular, Inc. ~ay 1, 1974 Cracking of p.c. concrete slabs can be reduced .by allowing them to be free floating. Slabs exterior to the structure must not be connected to the footings, as they wil-1--recieve some differential vertical movement due to frost action. Control joints should be placed at each change in section or direction and at not more than ~he width of the slab as appro- priate .to the work. The exposure of p.c. concrete thin sections such as curb gutter, walks, and drives, parti- cularly %£nere exposed to eve drippings, de-icing salts and other actions which cause frequent melting and drying and/or freezing and thawing is among the most severe environmental conditions for that material. The degree of protection from exposure is coupled to the curing period as well as the air entrainment and cement factor of the mix. Thus, we routinely suggest that p.c. concrete placed between mid-September and May include at least 5.5 sacks of portland cement/cubic yard, and "pozzolith", or at least 6 sacks of portland cement/cubic yard; that air entrainment be near the upper accepted limits, 6! 1.5% for 3/4" maximum size aggregate concrete and the slump be the least commensurate with placing and finishing operations (4" slt~p is adequate to this purpose); and that the concrete be surface dry or drier prior to being exposed to freezing temperatures (i.e., after initial cure, allow to dry before turning heat off in temperature protectcd work). ~ere de-icing agents are used, the owner should be warned that he %~ill eventually damage the concgete. That damage is often slowed substantially by periodic treatment with linseed oil cut 3:1 with gasoline or other thinner. The common application periods are at one year and then at three year intervals. DISCUSSION Subsurface exploration was conducted on April 23 ~nd 24, 1974, and consisted of two test holes 15' deep, with sampling at 5' intervals. .Standard penetration tests are made with a 140 · pound harmner free-falling a distance of 30" to advance a 2" diameter split-spoon sampler into the s~il. The blows for each 6" increment are recorded on the logs. The number of b]~qs (I~) required to drive the sampler 12" is referred to as the ~Standard Penetration." Grab samples were taken by pulling the auger out of the test hole and removing the sample from the flights of the auger near the bit. Disturbed samples were taken and classified visually in the field in accordance with the method shown on Sheets 4 and 5. Ali. test holes were drilled by Denali Drilling, Inc. with a truck mounted mobile B-50 drill employing a hollow-stem continuous flight auger. Drilling was supervised J. A. Modular, Inc. 6 ' ~!ay 1, 1974 and the holes were logged by B. D. Kenworthy, technician of our staff. The materials encountered in each test hole were very similar, although the test holes were separated by quite a distance. with the major soil group being a silty sandy gravel. Free water was not observed in either test hole to a depth of 15'. Proper site grading is very important on both lots, and when con%bined with ~he surface seal described in the "Recommendations" (2d, 2b, 2) sh6uld discourage the intrusion of surface water through the disturbed zone along the outboard face of the perimeter .footing. For the structure on lot 37, because of the daylight basement, further provision for subsurface drainage is warranted. Well constructed.footing drains are recommended (Sec. 3b), laid to drain by gravity to daylight. This report was directed toward the soil conditions expected to most influence the site. The treatment is not necessarily exhaustive of the possibilities, therefore, please feel free to contact the writer as the project developes. Very truly yours, ALASKA TESTLAB ~J. M.
