1.0 SUMMARY
A brief summary of pertinent findings, conclusions and recommendations are presented below.
This information should not be utilized in design or construction without reading the report in its
entirety and paying particular attention to the recommendations presented in the text and
Appendix.
1.1
GENERAL
•
Four soil test borings (B-1 through B-4) were drilled at the subject site during this exploration.
Generally, the borings encountered a surface veneer of asphalt underlain by gravel, previously
placed fill materials, residual soils and partially weathered rock.
•
Fill soils were encountered in borings B-2 and B-3 at depths of 11 and 6 feet beneath the
existing ground surface, respectively. The fill materials were generally described as sandy silt
with rock fragments and with a consistency of stiff to very stiff.
•
Partially weathered rock was encountered in borings B-1 and B-3 at depths ranging from 43 to
28 feet below the existing ground surface, respectively. Auger refusal materials were not
encountered in any of the borings above the boring termination depths of 20 to 50 feet below
the existing ground surface.
1.2
•
1.3
•
1.4
•
SITE PREPARATION
The majority of the encountered fill soils were fine grained soils. Although we do not
anticipate groundwater control problems, establishing subgrades in fine grained soils exposed
to inclement weather conditions can be challenging and may require drying and/or stabilizing
depending on the time of year and weather conditions.
FOUNDATIONS
We recommend that the proposed structure be supported on conventional shallow foundations
designed for a maximum allowable soil bearing pressure of 3,000 pounds per square foot (psf).
SEISMIC
In accordance with Section 1613.5.2 of the 2006 International Building Code, the seismic Site
Class was estimated using the standard penetration resistance values obtained from the soil test
borings performed during this study. Based upon this analysis, and our knowledge of general
subsurface conditions in the area, we believe the soil profiles associated with a Site Class “D”
are generally appropriate for this site.

2.0 INTRODUCTION
2.1
PROJECT INFORMATION
Our understanding of this project is based on discussions with Mr. Henry Gomez of Cobb County
School District, review of the provided site plans, a site reconnaissance during boring layout, and
our experience with similar projects.
The project site is located on the existing King Springs Elementary School campus located at 1041
Reed Road in Smyrna, Cobb County, Georgia.
We understand that the proposed construction will consist of a one-story addition. Final column
loads were not available at the time of issuance of this report. However, based upon previous
experience with similar structures, we estimate that compressive column loads will be on the
order of 80 to 100 kips, respectively. Wall loading is expected to be on the order of 2 to 3 kips
per linear foot. The planned first floor elevation of the building is currently proposed as 1015.5
feet-MSL. Minimal cuts and fills (on the order of 5 feet) are anticipated to achieve design grades.
2.2
SCOPE OF WORK
Cobb County School District engaged NOVA to provide geotechnical engineering consulting
services for the King Springs Elementary School project. This report briefly discusses our
understanding of the project, describes our exploratory procedures and presents our findings,
conclusions and recommendations.
The primary objective of this study was to perform a geotechnical exploration within the area of
the proposed construction and to assess these findings as they relate to geotechnical aspects of the
planned site development. The authorized geotechnical engineering services included a site
reconnaissance, a soil test boring and sampling program, engineering evaluation of the field data,
and the preparation of this report.
The services were performed substantially as outlined in the NOVA and Cobb County School
District RFP 34-10 Geotechnical Services contract dated August 3, 2010, and in general
accordance with industry standards.
As authorized per the above referenced contract, the completed geotechnical report was to include:
•
•
A description of the site, fieldwork, laboratory testing and general soil conditions
encountered, as well as a Boring Location Plan and individual Boring Records.
Discussion on potential design/construction issues indicated by the exploration, such as
materials that would require difficult excavation techniques, shallow groundwater table, etc.

NOVA Project Number 2011019
Recommendations for controlling groundwater and/or run-off during construction and, the
need for permanent de-watering systems based on the anticipated post construction
groundwater levels.
Recommendations for foundation design and construction, including allowable bearing
capacities and bearing depths.
Estimate of total and differential settlements of foundation based on available structural
loading data.
Recommended quality control measures (i.e. sampling, testing, and inspection requirements)
for site grading and foundation construction. Soil compaction requirements for foundations,
structural fill and pavements were to be provided.
Slab-on-grade construction considerations based on the geotechnical findings, including the
need for a sub-slab vapor barrier or a capillary barrier.
Suitability of on-site soils for re-use as structural fill and backfill. Additionally, the criteria
for suitable fill materials were to be provided.
Seismic site classification using correlation with SPT N-values in accordance with the 2006
International Building Code.
Site preparation considerations that include geotechnical discussions regarding site stripping
and subgrade preparation, recommended cut or fill slopes, and engineered fill/backfill
placement.
The assessment of the presence of wetlands, floodplains or water classified as State Waters of
Georgia was beyond the scope of this study. Additionally, the assessment of site environmental
conditions, including the detection of pollutants in the soil, rock or groundwater, at the site was also
beyond the scope of this geotechnical study. If desired by the client, NOVA can provide these
services.

3.0 SITE DESCRIPTION
3.1
GENERAL
The site is the existing King Springs Elementary School campus located at 1041 Reed Road in
Smyrna, Cobb County, Georgia. The site is bounded by residential and educational development
to the north, residential development to the east, Reed Road then residential development to the
south, and Gann Road then residential development to the west.
Based on the provided site plan, current site grades in the area of the proposed addition range
from 1015.5 feet-MSL at the existing building to 1012 feet-MSL along the entrance drive just
south of the proposed addition.
Currently, the site is developed as an existing elementary school with several rectangular shaped
buildings, playground areas, and associated surface asphalt-paved parking and drive areas. The site
is also landscaped with trees, shrubs and grassed areas. Based on a limited visual assessment of the
existing structures, no distress or other evidence was noted that would indicate foundation related
support problems. We note however that the type, bearing design and design loading of
foundations for these structures are unknown.
3.2
GEOLOGY / HYDROLOGY
3.2.1 Site and Area Geology
The site is located in the Piedmont Geologic Region, a broad northeasterly trending province
underlain by crystalline rocks up to 600 million years old. The Piedmont is bounded on the
northwest by the Blue Ridge Range of the Appalachian Mountains, and on the southeast by the
leading edge of Coastal Plain sediments, commonly referred to as the “Fall Line”. Numerous
episodes of crystal deformation have produced varying degrees of metamorphism, folding and
shearing in the underlying rock. The resulting metamorphic rock types in this area of the Piedmont
are predominantly a series of Precambrian age schists and gneisses, with scattered granitic or
quartzite intrusions.
According to the "Geology of the Greater Atlanta Region" by McConnell and Abrams, 1984, the
site is generally underlain by the Sandy Springs Group. This geologic formation typically consists
of intercalated biotite gneiss, mica schist and amphibolite.
Residual soils in the region are primarily the product of in-situ chemical decomposition of the
parent rock. The extent of the weathering is influenced by the mineral composition of the rock and
defects such as fissures, faults and fractures. The residual profile can generally be divided into three
zones:
Page 4
King Springs Elementary School
Cobb County School District
March 17, 2011
NOVA Project Number 2011019
•
An upper zone near the ground surface consisting of red clays and clayey silts which have
undergone the most advanced weathering,
•
An intermediate zone of less weathered micaceous sandy silts and silty sands, frequently
described as “saprolite”, whose mineralogy, texture and banded appearance reflects the structure
of the original rock, and
•
A transitional zone between soil and rock termed partially weathered rock (PWR). Partially
weathered rock is defined locally by standard penetration resistances exceeding 100 blows per
foot.
The boundaries between zones of soil, partially weathered rock and bedrock are erratic and
poorly defined. Weathering is often more advanced next to fractures and joints that transmit
water, and in mineral bands that are more susceptible to decomposition. Boulders and rock lenses
are sometimes encountered within the overlying PWR or soil matrix. Consequently, significant
fluctuations in depths to materials requiring difficult excavation techniques may occur over short
horizontal distances.
3.2.2 Groundwater
Groundwater in the Piedmont typically occurs as an unconfined or semi-confined aquifer
condition. Recharge is provided by the infiltration of rainfall and surface water through the soil
overburden. More permeable zones in the soil matrix, as well as fractures, joints and
discontinuities in the underlying bedrock can affect groundwater conditions. The groundwater
table in the Piedmont is expected to be a subdued replica of the original surface topography.

4.0 FIELD AND LABORATORY PROCEDURES
4.1
FIELD EXPLORATION
Boring locations were specified on the Foundation and Framing Plans prepared by Willett
Engineering Company and were established in the field by NOVA personnel by taping and
estimating distances and angles from site landmarks. Underground and overhead utility related
adjustments of the boring locations were made at the time of the field exploration. Boring
elevations were then interpolated from the provided topographic survey. Consequently, referenced
boring locations and elevations are approximate. If increased accuracy is desired by the client,
NOVA recommends that the boring locations and elevations be surveyed.
Our field exploration was conducted on March 12, 2011 and included four soil test borings (B-1
through B-4) drilled to depths of 20 to 50 feet below the existing ground surface in the area of the
proposed addition. All drilling and sampling operations were performed in general accordance with
ASTM designations.
Test Boring Records in the Appendix show the standard penetration test (SPT) resistances, or “Nvalues”, and present the soil conditions encountered in the borings. These records represent our
interpretation of the subsurface conditions based on the field exploration data, visual examination
of the split-barrel samples, and generally accepted geotechnical engineering practices. The
stratification lines and depth designations represent approximate boundaries between various
subsurface strata. Actual transitions between materials may be gradual.
The groundwater levels reported on the Test Boring Records represent measurements made at the
completion of the soil test boring. The soil test borings were subsequently backfilled with the soil
cuttings.
4.2
LABORATORY TESTING
Split-barrel samples were returned to our testing laboratory, where they were classified using
visual/manual methods in accordance with the Unified Soil Classification System (USCS) and
ASTM designations. The descriptions presented in the boring logs should be considered
approximate. Further laboratory testing was beyond the scope of this exploration.

5.0 SUBSURFACE CONDITIONS
5.1
SOIL CONDITIONS
The following paragraphs provide generalized descriptions of the subsurface profiles and soil
conditions encountered by the borings conducted during this study. The Test Boring Records in the
Appendix should be reviewed to provide more detailed descriptions of the subsurface conditions
encountered at each boring location. Conditions may vary at other locations and times.
5.1.1 Surface Materials
The borings were performed within existing parking and drive areas and encountered up to 2
inches of asphalt underlain by up to 3 inches of gravel. Although not encountered in any of the
borings, concrete walkways were present in the area of the proposed addition.
5.1.2 Fill
Fill was encountered in borings B-2 and B-3 to depths of 11 and 6 feet below the existing ground
surface, respectively. The fill was generally described as sandy silt with rock fragments and a
consistency of stiff to very stiff. Standard penetration resistances in the fill varied from 9 to 21
blows per foot (bpf), but may have been amplified by the presence of rock fragments.
5.1.3 Residual Soils
Residual soils were encountered in all borings beneath the fill materials or ground surface. The
residuum was generally described as sandy silt. Standard penetration resistance values ranged from
14 to 63 bpf, but more typically varied from 18 to 28 bpf.
5.1.4 Partially Weathered Rock
Partially weathered rock (PWR) is a transitional material between soil and the underlying parent
rock that is defined locally as materials that exhibit a standard penetration resistance exceeding 100
bpf. PWR was encountered in borings B-1 and B-3 at depths of 43 and 28 feet below the ground
surface (approximate elevations of 970 and 986 feet-MSL), respectively.
5.1.5 Auger Refusal Materials
Auger refusal materials are any very hard or very dense material, frequently boulders or the upper
surface of bedrock, which cannot be penetrated by a power auger. Auger refusal was not
encountered in any of the borings above the boring termination depths of 20 to 50 feet below the
existing ground surface.

GROUNDWATER CONDITIONS
Groundwater was observed at the time of boring in borings B-1 and B-3 at depths of 46 and 38 feet
below the existing ground surface (approximate elevations of 967 and 976 ft-MSL). Groundwater
levels vary with changes in season and rainfall, construction activity, surface water runoff and
other site-specific factors. Groundwater levels in the Smyrna area are typically lowest in the late
summer-early fall and highest in the late winter-early spring; consequently, the water table may
vary at times.

6.0 CONCLUSIONS AND RECOMMENDATIONS
The following conclusions and recommendations are based on our understanding of the proposed
construction, site observations, our evaluation and interpretation of the field data obtained during
this exploration, our experience with similar subsurface conditions, and generally accepted
geotechnical engineering principles and practices.
Subsurface conditions in unexplored locations or at other times may vary from those encountered
at specific boring locations. If such variations are noted during construction, or if project
development plans are changed, we request the opportunity to review the changes and amend our
recommendations, if necessary.
As previously noted, boring locations were established by estimating distances and angles from site
landmarks. If increased accuracy is desired by the client, we recommend that the boring locations
and elevations be surveyed.
6.1
SITE GRADING
6.1.1 Site Preparation
General: An existing porte cochere that will require demolition currently occupies the site. Prior to
proceeding with construction, all slabs, foundations, pavements, vegetation, root systems, topsoil,
and other deleterious non-soil materials should be stripped from proposed construction areas.
Clean topsoil may be stockpiled and subsequently re-used in landscaped areas. Debris-laden
materials should be excavated, transported and disposed of off-site in accordance with
appropriate solid waste rules and regulations. All existing utility locations should be reviewed to
assess their impact on the proposed construction and relocated/grouted in-place as appropriate.
After clearing and stripping, areas which are at grade or will receive fill should be carefully
evaluated by a NOVA geotechnical engineer. The engineer will require proofrolling of the
subgrade with multiple passes of a 20 to 30 ton loaded truck or other pneumatic-tired vehicle of
similar size and weight. The purpose of the proofrolling is to locate soft, weak, or excessively wet
fill or residual soils present at the time of construction. Any unstable materials observed during the
evaluation and proofrolling operations should be undercut and replaced with structural fill or
stabilized in-place by scarifying and re-densifying.

Existing/Old Fill: Previously placed fill materials were encountered during this exploration.
Based on our experience, we anticipate fill materials likely exist at other locations between our
borings. Old fills are frequently erratic in composition and consistency. In the event that low
consistency and/or debris laden fill materials are encountered during construction, typical
recommendations would include undercutting and backfilling with structural fill and/or
stabilizing in-place with fabric, stone, and/or other remedial techniques. Actual remedial
recommendations can best be determined by the geotechnical engineer in the field at the time of
construction.
6.1.2 Difficult Excavation
None of the borings encountered dense soil, PWR or rock above planned finished grades.
Therefore, we do not anticipate that significant quantities of materials requiring difficult excavation
techniques will be encountered during mass grading and/or shallow foundation/utility excavation
operations.
6.1.3 Fill Placement
Fill materials should be low plasticity soil (Plasticity Index less than 30), free of non-soil materials
and rock fragments larger than 3 inches in any one dimension. Based on visual examination, the
existing residual soils and much of the existing fill, which does not contain appreciable amounts of
debris, rock, organics or other deleterious materials encountered during this exploration generally
appear suitable for re-use as structural fill. Prior to construction, bulk samples of the proposed fill
materials should be laboratory-tested to confirm their suitability.
Organic and/or debris laden material is not suitable for re-use as structural fill. Topsoil, mulch
and similar organic materials can be wasted in architectural areas. Debris-laden materials should
be excavated, transported and disposed of off-site in accordance with appropriate solid waste
rules and regulations.
Fill should be placed in thin, horizontal loose lifts (maximum 8-inch) and compacted to at least
95 percent of the standard Proctor maximum dry density (ASTM D 698). The upper 8 inches of
soil beneath pavements and slab-on-grade should be compacted to at least 98 percent. In
confined areas, such as utility trenches or behind retaining walls, portable compaction equipment
and thinner fill lifts (3 to 4 inches) may be necessary. Fill materials used in structural areas
should have a target maximum dry density of at least 95 pounds per cubic foot (pcf). If lighter
weight fill materials are used, the NOVA geotechnical engineer should be consulted to assess the
impact on design recommendations.

NOVA Project Number 2011019
Soil moisture content should be maintained within 3 percent of the optimum moisture content. Fine
grained soils were encountered at the planned finished subgrade elevations at each of the boring
locations. Although we do not anticipate significant groundwater control problems based on the
stabilized groundwater levels, establishing subgrades in these fine grained soils may be challenging
and could require drying and/or stabilization depending on the time of year and weather conditions
when grading is performed. We recommend that the grading contractor have equipment on site
during earthwork for both drying and wetting fill soils. Moisture control may be difficult during
rainy weather.
All filling operations should be observed by a NOVA soils technician, who can confirm
suitability of material used and uniformity and appropriateness of compaction efforts. The
NOVA soils technician can also document compliance with the specifications by performing
field density tests using thin-walled tube, nuclear, or sand cone testing methods (ASTM D 2937,
D 6938, or D 1556, respectively). One test per 400 cubic yards and every 2 feet of placed fill is
recommended, with test locations well distributed throughout the fill mass. When filling in small
areas, at least one test per day per area should be performed.
6.2
GROUNDWATER CONTROL
During the current study, depths to groundwater ranged from 46 to 38 feet below the existing
ground surface (approximate elevations ranging from 967 to 976 feet-MSL). Based on the
planned cuts necessary to reach design subgrades, we do not anticipate significant groundwater
control problems during mass grading operations. The groundwater appears to be below planned
slab elevations.
As previously noted, groundwater levels are subject to seasonal, climatic and other variations and
may be different at other times and locations. The extent and nature of any dewatering required
during construction will be dependent on the actual groundwater conditions prevalent at the time of
construction and the effectiveness of construction drainage to prevent run-off into open
excavations.
6.3
FOUNDATIONS
After the recommended site and subgrade preparation and fill placement, we recommend that the
proposed structure be supported by conventional shallow foundations. Foundations bearing on
undisturbed residual soils and/or compacted structural fill may be designed for a maximum
allowable bearing pressure of 3,000 pounds per square foot (psf).
Previously placed fill materials were encountered on the site. In the event that low consistency or
debris-laden fill materials are present in foundation excavations, undercutting and backfilling with
crushed stone or structural fill or redesigning for a reduced bearing pressure, may be required.

We recommend minimum footing widths of 24 inches for ease of construction and to reduce the
possibility of localized shear failures. Exterior footing bottoms should be at least 18 inches below
exterior grades for protection against frost damage.
Settlements for spread foundations were assessed using SPT values to estimate elastic modulus,
based on published correlations and previous NOVA experience. We note that the settlements
presented are based on random field data and an assumed subsoil profile. Conditions may be better
or worse in other areas; however, we believe the estimated settlements are reasonable.
Based on column loadings, soil bearing capacities and the presumed foundation elevations as
discussed above, we expect primary total settlement beneath individual footings to be on the order
of ¾ to 1 inches.
The amount of differential settlement is difficult to predict because the subsurface and foundation
loading conditions can vary considerably across the site. However, we anticipate differential
settlement between adjacent footings could vary from ¼ to ½ inch. The final deflected shape of the
structure will be dependent on actual footing locations and loading.
Foundation support conditions are highly erratic and may vary dramatically in short horizontal
distances. It is anticipated that the geotechnical engineer may recommend a different bearing
capacity upon examination of the actual foundation subgrade at numerous locations.
To reduce the differential settlement if lower consistency materials are encountered, a lower
bearing capacity should be used or the foundations should be extended to more competent
materials. We anticipate that timely communication between the geotechnical engineer and the
structural engineer, as well as other design and construction team members, will be required.
All footing excavations should be evaluated by the NOVA geotechnical engineer prior to
reinforcing steel placement to observe foundation subgrade preparation and confirm bearing
pressure capacity.
Footing excavations should be level and free of debris, ponded water, mud, and loose, frozen or
water-softened soils. Concrete should be placed as soon as is practical after the footing is
excavated and the subgrade evaluated. Foundation concrete should not be placed on frozen or
saturated soil. If a footing excavation remains open overnight, or if rain or snow is imminent, a 3
to 4-inch thick "mud mat" of lean concrete should be placed in the bottom of the footing to
protect the bearing soils until reinforcing steel and concrete can be placed.

SLAB-ON-GRADE
The conditions exposed at subgrade levels will vary across the site and may include existing fill
materials, newly placed structural fill or residual soils. Provided the existing fill material does not
deflect or “pump” during the proofroll, slabs-on-grade may be adequately supported on these
subgrade conditions subject to the recommendations in this report. Slabs-on-grade should be
jointed around columns and along walls to reduce cracking due to differential movement. A 6-inch
layer of crushed stone may be placed beneath the building slabs to reduce non-uniform support
conditions. An underdrain system is not necessary beneath the slabs, but an impermeable vapor
barrier is recommended beneath finished spaces to reduce dampness.
Once grading within the building footprint is completed, the subgrade is usually exposed to
adverse construction activities and weather conditions during the period of sub-slab utility
installation. The subgrade should be well-drained to prevent the accumulation of water. If the
exposed subgrade becomes saturated or frozen, the geotechnical engineer should be consulted.
After utilities have been installed and backfilled, a final subgrade evaluation should be performed
by the geotechnical engineer immediately prior to slab-on-grade placement. If practical, proofrolling
may be used to redensify the surface and to detect any soil that has become excessively wet or
otherwise loosened.
6.5
SEISMIC
6.5.1 Soil Site Class
In accordance with Section 1613.5.2 of the 2006 IBC, the seismic Site Class was estimated using
the standard penetration resistance values obtained from the soil test borings performed during this
study. Based upon this analysis, and our knowledge of general subsurface conditions in the area, we
believe the soil profiles associated with a Site Class “D” are generally appropriate for this site.
We note that the IBC allows determination of Site Class using in-situ seismic shear wave survey
techniques. It should be noted that use of this supplemental method does not guarantee a lower site
class designation; however, it is a reasonable and prudent approach that can be performed in a
supplemental study, if requested.

CONSTRUCTION OBSERVATIONS
6.6.1 Shallow Foundations
Footing excavations should be level and free of debris, ponded water, mud, and loose, frozen or
water-softened soils. All footing excavations should be evaluated by the NOVA geotechnical
engineer prior to reinforcing steel placement to observe foundation subgrade preparation and
confirm bearing pressure capacity. Due to variable site subsurface and construction conditions,
some adjustments in isolated foundation bearing pressures, depth of footings or undercutting and
replacement with controlled structural fill may be necessary.
6.6.2 Subgrade
Once site grading is completed, the subgrade may be exposed to adverse construction activities and
weather conditions. The subgrade should be well-drained to prevent the accumulation of water. If
the exposed subgrade becomes saturated or frozen, the NOVA geotechnical engineer should be
consulted.
A final subgrade evaluation should be performed by the NOVA geotechnical engineer
immediately prior to pavements or slab-on-grade placement. If practical, proofrolling may be
used to re-densify the surface and to detect any soil, which has become excessively wet or
otherwise loosened.

QUALIFICATIONS OF
RECOMMENDATIONS
QUALIFICATIONS OF RECOMMENDATIONS
The findings, conclusions and recommendations presented in this report represent our
professional opinions concerning subsurface conditions at the site. The opinions presented are
relative to the dates of our site work and should not be relied on to represent conditions at later
dates or at locations not explored. The opinions included herein are based on information
provided to us, the data obtained at specific locations during the study and our past experience. If
additional information becomes available that might impact our geotechnical opinions, it will be
necessary for NOVA to review the information, reassess the potential concerns, and re-evaluate
our conclusions and recommendations.
Regardless of the thoroughness of a geotechnical exploration, there is the possibility that
conditions between borings will differ from those encountered at specific boring locations, that
conditions are not as anticipated by the designers and/or the contractors, or that either natural
events or the construction process have altered the subsurface conditions. These variations are an
inherent risk associated with subsurface conditions in this region and the approximate methods
used to obtain the data. These variations may not be apparent until construction.
The professional opinions presented in this geotechnical report are not final. Field observations and
foundation installation monitoring by the geotechnical engineer, as well as soil density testing and
other quality assurance functions associated with site earthwork and foundation construction, are
an extension of this report. Therefore, NOVA should be retained by the owner to observe all
earthwork and foundation construction to document that the conditions anticipated in this study
actually exist, and to finalize or amend our conclusions and recommendations. NOVA is not

ALTERNATES
SECTION 01101
ALTERNATES
PART ONE-GENERAL
1.01
BIDDING REQUIRMENTS
CCSD may use deductive alternates to reduce the base bid on state- funded projects using the
design/bid/build construction delivery method; however, the deductive alternates shall be bid
prioritized and exercised in numerical sequence as used in the bid documents. When the CCSD
determines that deductive alternatives must be selected, all bids will be recalculated removing the
deductive alternates to be taken. The low bid shall then be determined on the base bid less any
deductive alternates.
The plans and specifications shall indicate if the project will be awarded by base bid or base bid plus
selected alternates. Additive alternates may be exercised in any order. If the plans and specifications
state that the contract will be awarded on base bid, then additive alternates are considered only after
the low base bidder has been declared. If the plans and specifications state that the project will be
awarded by base bid plus additive alternates, all bids will be recalculated adding the additive
alternates to be taken. The low bid shall then be determined on the base bid plus the selected additive
alternates.
1.02
DESCRIPTION:
A.
An alternate is an amount proposed by bidders, and stated on the Bid Form, for certain
work defined in the Bidding Requirements that may be added to or deducted from the
Base Bid amount if the Owner decides to accept a corresponding change in either the
amount of construction to be completed, or in the products, materials, equipment,
systems, or installation methods described in the Contract Documents.
B.
The cost or credit for each alternate is the net addition to or deduction from the Contract
Sum to incorporate the Alternate into the Work. No other adjustments are made to the
Contract Sum.
C.
Related Work Described Elsewhere:
1.
Materials and methods to be used in the Base Bid and in the Alternates have
been described on the Drawings and in pertinent Sections of these Specifications.
2.
Method for stating the proposed Contract Sum is described in the bid form.
1.03
All alternates described in this Section are required to be reflected on the Bid Form as submitted
by Bidders. Do not submit Alternates other than as described in this Section.
1.04
If the Owner elects to proceed on the basis of one or more of the Alternates, the Contractor shall
make all modifications to the work required in furnishing and installing the selected Alternates to
the approval of the Architect and at no additional cost to the Owner other than as proposed on the
Bid Form.
1.05
All Alternates must be executed with an appropriate response. A "blank space", or a "No Bid"
statement is inappropriate. The space must include a "Specific Sum" or a "No Change in Price"
statement. Failure to provide this information may be cause for rejection of the bid at the Owner's
discretion.
1.06
Proposal amounts for Alternates shall remain open for acceptance by the Owner for (60) sixty
days after the Notice of Award date.
1.07
If liquidated damages are deleted by Alternate, Addendum or Change Order, completion time
remains unchanged and time is still the essence of the contract and in lieu of liquidated damages
the Owner retains the right to pursue the collection of actual damages for delayed completion,
pursuant to the provisions of the contract documents, under existing state statutes and/or law.
