EEC Project No. 1164046
Mr. Jordan:
As requested, during the period April 10 through April 22, 2017, Earth Engineering Consultants,
LLC (EEC) personnel provided construction observation and testing services for the proposed
Estes Valley Community Center expansion project currently under construction at 660
Community Drive in Estes Park, Colorado. The services provided during the referenced period
were on a part-time/on-call as-needed basis and included observation and field density testing of
prepared foundation bearing strata material, building backfill/pool apron subgrade material, and
water line, storm sewer and sanitary sewer backfill material as described herein, observations of
foundation and slab-on-deck (SOD) reinforcing steel, periodic site observations during the
concrete masonry unit (CMU) wall construction for various wall alignments, observations of
drilled and epoxy set all-threaded anchor bolts at locations as described herein, observations of
non-destructive testing (NDT) services, along with testing of masonry grout and cast-in-place
concrete for the referenced project. The results of the site observations and testing services
completed by EEC personnel during the referenced period are included with this report.
Field Density Testing and Observation Services
During the referenced period, EEC personnel performed field density tests on prepared
foundation bearing strata material, building backfill/pool apron subgrade material, and of water
line, storm sewer, and sanitary sewer backfill material as described herein, which was
prepared/placed and compacted prior to and/or during our site visits. The field density tests were

completed at random locations and elevations within the areas tested and were performed in
general accordance with ASTM Specification D6938. The field density test results and
approximate location of each test completed during the referenced period are shown on the
attached summary sheet and the associated site diagrams. The field density test results except for
Consecutive Test No. 235 conformed to the project specific compaction requirement of at least
95% or 98% of standard Proctor maximum dry density (ASTM D698), as required. It is our
understanding the area of Consecutive Test No. 235 was to be reworked and retested at a later
date.
Foundation Reinforcement Observations
During the referenced period, EEC personnel conducted site visits on April 10 through 12, 2017,
to perform visual observations of the reinforcing steel placed within portions of the building’s
foundation alignments and SOD, at the gridlines identified on the enclosed “color-
coded/highlighted” site diagrams, prior to placement of concrete.
The reinforcement for the portion of the SOD as indicated herein was placed in general
accordance with the Metal Deck Slab Schedule detail 10/S530 along with details and notes
presented on pages S103, S390, S500, S530, and S531 of the structural drawings.
The reinforcement for the footings was placed in general accordance with the “Footing
Schedule” as presented on page S300 and details as presented on pages S300 and S301 of the
structural drawings. The reinforcement for the stem wall and foundation wall alignments was
placed in general accordance with the details as presented on pages S300, S301 and S305 of the
structural drawings. The vertical dowels continuing into the CMU walls above, where
appropriate, were installed to match the CMU reinforcement as per the plans and specifications.
Any discrepancies of reinforcement during the various daily site visits were brought to the
attention of the project’s construction management consultant, and the reinforcement
subcontractor, during the initial site visit and corrections/modifications were addressed
accordingly prior to placement of concrete.
Clearances and lap lengths, where applicable, were checked and appeared to meet the minimum
requirements. The horizontal and vertical reinforcement for the portion of the foundation system
as noted herein and observed by EEC personnel on the dates indicated, appeared to be in general

accordance with details presented on the structural drawings prepared by Martin and Martin
Consulting Engineers, dated January 12, 2017, and/or the shop drawings prepared by Barton
Supply, dated December 22 and 28, 2016. The shop drawings were used as a reference to
provide clarity when specific details were not presented on the structural drawings.
Concrete Masonry Unit (CMU) Wall Construction Observations
During the referenced period, EEC personnel observed portions of the reinforcing steel and other
structural related elements during the 8 to 12-inch by 16-inch standard block CMU wall
construction at the gridlines identified on the enclosed “color-coded/highlighted” site diagram.
Layout of the CMU wall alignments were provided by others. During each daily site visit, (April
17 through 21, 2017), EEC personnel observed CMU wall construction at the various wall
alignments and recorded approximate gridline locations, elevations/courses for each day, along
with the observed horizontal and vertical reinforcement requirements and grout placement as
needed.
The vertical reinforcement for the various walls, in general, consisted of one (1) #5 rebar spaced
32 to 48 inches on-center, along with an additional #5 rebar positioned at each end of walls, at
each corner, and along each side of openings, control joints and/or expansion joints. The
horizontal reinforcement consisted of 9-gauge “ladder-type” reinforcement spaced every 16-
inches on-center full-height of each CMU wall. At the various bond beam locations, below and
above windows, beam pockets, and at openings, where noted on the structural drawings, EEC
personnel noted the reinforcement consisted of two (2) or one (1) continuous #5 within the fully-
grouted cell alignments.
The horizontal and vertical reinforcement for the portions of the CMU walls and observed by
EEC personnel during the referenced timeframe on a periodic basis as noted herein appeared to
be in general accordance with details presented on the structural drawings. During the grouting
operations, EEC personnel observed grout placement within the low lifts. Lap lengths, where
applicable, were checked and appeared to meet the minimum required lengths.
During the CMU construction phase for the project, EEC personnel tested/evaluated the grout
material used within portions of the wall alignments, as identified herein, (please refer to EEC’s
Grout Set No. 3). Grout compressive strength cylinders, (approximately 4-inch diameter by 7-
5/8 inches in length), were molded on-site in general accordance with ASTM specifications. The

grout cylinders were molded on-site within CMU blocks used to construct the CMU walls, and
were extracted/cored using a 4-inch inside diameter diamond bit core barrel upon retrieval and
delivery to our Windsor laboratory 2 days following the initial preparation of the specimens.
Results of the field and 7-day laboratory tests performed during the referenced period are
provided herein.
Drilled and Epoxied Anchor Bolt Observations
For the drilled and epoxy set column anchors for misplaced or damaged anchor bolts previously
set at approximate Gridlines D by 8 and F by 7, we observed 16-inch in length, ¾-inch diameter
all-thread anchor bolts set in drilled and brush cleaned holes approximately 9 inches in depth and
set/secured in place with Hilti HIT-HY 200R epoxy injected into the hole.
Non-Destructive Testing (NDT) Services
During the referenced period EEC’s in-house certified bolt and weld inspector conducted
observations on April 17, 2017 of the upper level north structural framing located in the
approximate area of Gridlines A2.4 through A6 from AE through AG, as well as post installed
perimeter angle threaded rods along Gridlines AG.8 from A5.4 through A6, and along A5.4 from
AG.8 through AH. A summary report describing our observations is attached with this report
and was provided verbally to the contractor immediately following our site observations. The
work in the area of the referenced lines observed by EEC during the referenced period appeared
to be in general accordance with the project plans and details dated January 12, 2017.
During the referenced period on April 10, 17, and 19, 2017, site visits were conducted by an
independently hired 3rd party consultant, Intermountain Testing Company, as requested by
Adolfson & Peterson Construction, to provide ultrasonic examination of all visually acceptable
complete joint penetration (CJP) welded moment connections as well as field welded structural
steel components as described herein. Those reports are appended for reference.
Testing of Cast-in-Place Concrete
During the referenced period, EEC personnel observed and tested Portland cement concrete
delivered to the site for placement as indicated on the enclosed daily reports for the referenced
project, (please refer to Set Nos. 30 through 33). Field testing performed on the plastic concrete
