GENERAL NOTES
1. The Contractor shall attend an on-site preconstruction conference with Brunswick County Schools representative(s)
and the Engineer prior to beginning work.
2. Survey data was provided by Bobby Long & Associates; Shallotte, NC
3. All work shall be performed in compliance with all applicable local, state, and federal permits, codes, regulations,
and ordinances.
4. The Contractor shall locate underground utilities within the project work area prior to beginning work. He shall be
responsible for any damage to any above-ground or below-ground properties resulting from his activities.
5. Should the Contractor determine that existing conditions/features/factors may be in conflict with the project plans, he
shall immediately contact the Engineer for direction.
6. The Contractor shall take necessary action to minimize the tracking of mud onto paved roadway(s) and/or school
parking/drive areas.
7. The Contractor, to the extent possible, shall minimize the generation of dust or other airborne particulate matter.
8. Litter, construction debris, oils, fuels, building products, and construction chemicals that could be exposed to rainfall
and/or stormwater runoff shall be prevented from becoming a pollutant source in stormwater discharges.
9. Contractor shall ensure compliance with the Geotechnical Report by ECS Southeast, LLP titled "Geotechnical
Engineering Report South Brunswick High School - Tennis Courts" throughout all phases of construction.
CONSTRUCTION SEQUENCE
NOTE: This sequence is provided as a guide for limiting erosion and the loss of sediment to off-site areas. It is not
intended to dictate means and/or methods for the Contractor to perform his work. The Contractor is solely responsible
for preventing eroded soils from leaving the site. He shall use his best judgment in adjusting this sequence as may be
beneficial in meeting this intended goal.
1. Obtain a copy of the NCDEQ/LQS erosion control permit. Review the permit and become familiar with its
contents/requirements.
2. Schedule an on-site pre-construction conference with the NCDEQ/LQS personnel named on the erosion control
permit. Inform Brunswick County Schools and the Engineer about the date and time of the meeting.
3. Install the temporary gravel construction entrance.
4. Install the sediment fencing along the alignments shown on the plan.
5. Remove the existing asphalt while minimizing the removal of base material. Pulverize the asphalt and store in
stockpile area for future use as a reclaimed asphalt pavement (RAP) base material.
6. Remove the existing base and/or subgrade material to a depth of at least 7" below the proposed surface grade of
the tennis courts.
7. Construct the tennis court base by installing and compacting up to 2" of RAP, and then installing and compacting
a layer of ABC to provide a total base thickness (RAP plus ABC) of 4".
8. Perform the grading activities.
9. Install pavement sections of tennis court.
10. Install the erosion matting along the alignment of the swales.
11. Place the wattle check dams in the swales at locations shown on the project plan.
12. Stabilize all disturbed areas as set out in the “Grassing Notes”.
13. Inspect all erosion and sediment control practices weekly and after rainfall events. Make repairs as may be
needed.
14. After the site is stabilized, remove all temporary measures and apply permanent seeding, fertilizer, and mulching.
Water as necessary to establish a vigorous grass cover.
EROSION CONTROL AND STORMWATER NARRATIVE:
Brunswick County Schools desires to reconstruct the on-site tennis court at South Brunswick High School. The project
will entail removing the existing asphalt surface and base materials and replacing with a new base and asphalt surface.
The finished surface will have the same dimensions as the existing one and shall "occupy" the same location. No more
than 1.5 acres (inclusive of the tennis courts) will be disturbed during the performance of the work.
The primary temporary means for controlling erosion during construction will be sediment fencing, swale erosion liners,
wattle dams, and a construction entrance. The primary means for permanent surface stabilization will be permanent
seeding to establish a vigorous grass cover over the perimeter areas.
State Stormwater Management Permit No. SW8 881203 MOD is currently active relative to development within the
South Brunswick High School site. (The latest modification, dated October 4, 2018 relates to the proposed
construction of a hitting facility.) Since the current project entails removing existing BUA and installing new BUA over
the same footprint as the old BUA, a stormwater exemption will be requested.
This site drains to Moore Creek in the Cape Fear River Basin. The classification of Moore Creek at this location is
C;Sw. The Stream Index number is 18-86-1. No wetlands will be disturbed during the construction of this project.

Reference is made to Paragraph 4.1.1 of the Geotechnical Engineering
Report by ECS Southeast, LLP. This paragraph states that at two of the five
boring locations, the subgrade contained roots and/or organics at depths ranging
from 2 to 5.5'. The Contractor shall retain the services of a geotechincal
engineer (GE) to investigate the subsurface conditions and to provide
recommendations. The contractor shall include the services of the GE in his/her
Base Bid. The Contractor shall include in his/her bid documents an Alternate
Bid which would include a unit price, by cubic yard, for the excavating, filling, and
compacting of the poor subgrade areas.

The following summarizes the main findings of the exploration, particularly those that may have a cost impact on the planned development. Information gleaned from the executive summary should not be utilized in lieu of reading the entire geotechnical report.
The purposed of the geotechnical exploration was to provide geotechnical engineering recommendations for the proposed tennis courts at South Brunswick High School in Southport, Brunswick County, North Carolina.
The geotechnical exploration included five (5) asphalt cores and hand auger borings with Kessler Dynamic Cone Penetrometer (DCP) tests.
The hand auger borings generally encountered asphalt with thicknesses ranging from approximately 2 ¼” to 3” underlain by SAND (SM, SP-SM) with layers of SILT (ML).
It is important to note that the natural geology at the site has been modified in the past. Therefore, potential fill and unsuitable materials may be present at the site.
The pavement section for the tennis court should consist of at least 3 inches of surface mix asphalt overlying at least 4 inches of compacted aggregate base course.
The roots/organics present at select locations could cause cracks during the design life of the tennis courts depending on subgrade preparation.

The project site is located at the existing South Brunswick High School tennis courts at 280 Cougar
Rd in Southport, Brunswick County, North Carolina. Figure 2.1.1 below shows an image of where
the site is located.
Figure 2.1.1 Site Location
2.2 CURRENT SITE CONDITIONS
The site currently consists of an existing tennis court which exhibits both longitudinal and transverse cracking at select locations. A drainage ditch is present north of the tennis courts and runs parallel to Cougar Road. The site gradually slopes upward in the south to north orientation with approximate site elevations ranging from around 39 to 42 feet.
2.3 PROPOSED CONSTRUCTION
The project consists of removing and replacing the existing tennis courts and potentially reusing the existing asphalt as aggregate base.

3.0 FIELD EXPLORATION
3.1 FIELD EXPLORATION PROGRAM
The field exploration was planned with the objective of characterizing the project site in general geotechnical and geological terms and to evaluate subsequent field data to assist in the determination of geotechnical recommendations.
3.1.1 Hand Auger Borings and Kessler Dynamic Cone Penetrometer Tests
ECS explored the proposed roadway areas by performing five (5) asphalt cores, five (5) Kessler Dynamic Cone Penetrometer (DCP) tests and advancing five (5) hand auger borings (K-1 through K-5) to depths ranging from approximately 4 to 5½ feet below the existing subgrade at the site. The Kessler DCP is used to estimate the strength characteristics of soils. The Kessler DCP was continuously driven approximately 3 feet below the existing ground surface. The Kessler DCP is driven into the soil by dropping a Dual-Mass 17.6 lb Hammer from a height of 22.6 inches. The depth of cone penetration is measured at selected penetration or hammer drop intervals and the soil shear strength is reported in terms of Kessler DCP index. The Kessler DCP index is based on the average penetration depth resulting from one blow of the 17.6 lb hammer. The Kessler DCP index can be correlated to CBR and modulus of rigidity. The approximate boring locations are shown on the attached Exploration Location Diagram. The Hand Auger Boring Logs and the results of the Kessler DCP tests are presented in Appendix B.
3.2 REGIONAL/SITE GEOLOGY
It is important to note that the natural geology at the site has been modified in the past. Therefore, potential fill and unsuitable materials may be present at the site. The site is located in the Coastal Plain Physiographic Province of North Carolina. The Coastal Plain is composed of seven terraces, each representing a former level of the Atlantic Ocean. Soils in this area generally consist of sedimentary materials transported from other areas by the ocean or rivers. These deposits vary in thickness from a thin veneer along the western edge of the region to more than 10,000 feet near the coast. The sedimentary deposits of the Coastal Plain rest upon consolidated rocks similar to those underlying the Piedmont and Mountain Physiographic Provinces. In general, shallow unconfined groundwater movement within the overlying soils is largely controlled by topographic gradients. Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies. The elevation of the shallow water table is transient and can vary greatly with seasonal fluctuations in precipitation.

Based on the U.S. Geological Survey1,2 the site of the proposed construction lies within the Waccamaw Formation (Tpyw). The Waccamaw Formation typically consists of alluvial sand, silts, and clay. An overview of the general site geology is illustrated in Figure 3.2.1 below.

3.3 SUBSURFACE CHARACTERIZATION
The subsurface conditions encountered were generally consistent with published geological mapping. The following sections provide generalized characterizations of the soil encountered during our subsurface exploration. For subsurface information at a specific location, refer to the Boring Logs in Appendix B.
Table 3.3.1 Subsurface Stratigraphy Approximate Depth Range (ft)
Stratum Description
0 to 0.25 ft. (Surface cover)
n/a The surface cover material consisted of asphalt with thicknesses ranging from approximately 2¼” to 3”. Boring K-5 was underlain by approximately 4 inches of ABC stone.
0.25 to 5.5 ft. I Fine to Medium Silty and Slightly Silty SAND (SM, SP-SM) with layers of Clayey SILT (ML), Moist to Saturated.
3.4 GROUNDWATER OBSERVATIONS
Groundwater observations were made at the boring locations during exploration as noted on the boring logs in Appendix B. The apparent groundwater depths were observed at the time of exploration to have ranged from approximately 3.0 to 4.2 feet below ground surface at borings K-2, K-3 and K-5. Borings K-1 and K-4 were dry at the termination of the boring operations. The highest groundwater observations are normally encountered in the late winter and early spring. Variations in the long-term water table may occur as a result of changes in precipitation, evaporation, surface water runoff, construction activities, and other factors not immediately apparent at the time of this exploration. If long term water levels are crucial to the development of this site, it would be prudent to verify water levels with the use of perforated pipes or piezometers.

4.0 DESIGN RECOMMENDATIONS
4.1 SITE DESIGN CONSIDERATIONS
4.1.1 Tennis Court Design Recommendations Subgrade Characteristics: Based on the results of the hand auger borings, it appears that the tennis court subgrades will consist mainly of SANDS (SM, SP-SM). At boring locations K-2 and K-5, soil containing roots and soils containing organics were encountered from approximately 2 to 5½ feet beneath the existing ground surface. The roots/organics present at select locations could cause cracks during the design life of the tennis courts due to long organic decomposition. It is recommended that the subgrade be checked in the field during the construction process. Design Considerations: For the design and construction of the tennis courts, the subgrades should be prepared in strict accordance with the recommendations in the “Subgrade Preparation” and “Engineered Fill Placement” sections of this report and with the construction guidelines issued by the USTA and the American Sports Builders Association. The pavement section for the tennis court should consist of at least 3 inches of surface mix asphalt overlying at least 4 inches of compacted aggregate base course. Aggregate base course materials beneath pavements should be compacted to at least 95 percent of their modified Proctor maximum dry density (ASTM D 1557). An important consideration with the design and construction of pavements is surface and subsurface drainage. Where standing water develops, either on the pavement surface or within the base course layer, softening of the subgrade and other problems related to the deterioration of the pavement can be expected. Furthermore, good drainage should minimize the possibility of the subgrade materials becoming saturated during the normal service period of the pavement. Saturation of the subgrade materials and asphalt pavement areas results in a softening of the subgrade material and shortened life span for the pavement. Therefore, we recommend that both the surface and subsurface materials for the pavement be properly graded in accordance with the USTA and American Sports Builder Association guidelines. By quickly removing surface and subsurface water, softening of the subgrade can be reduced and the performance of the tennis courts can be improved. Site preparation for the tennis courts should consist of stripping, proofrolling, and the placement of compacted structural fill. Reclaimed Asphalt Pavement for Base Course: A specialty contractor can utilize an automated process that pulverizes the existing asphalt pavement and uses the reclaimed asphalt pavement (RAP) as aggregate base stone. A layer of RAP and a layer of ABC stone can be used to achieve the minimum aggregate bas thickness of 4 inches. The specialty contractor selector should determine how much RAP base can be generated.

5.0 SITE CONSTRUCTION RECOMMENDATIONS
5.1 SUBGRADE PREPARATION
5.1.1 Proofrolling After removing all unsuitable surface materials, cutting to the proposed grade, and prior to the placement of any structural fill or other construction materials, the exposed subgrade should be examined by the Geotechnical Engineer or authorized representative. The exposed subgrade should be thoroughly proofrolled with previously approved construction equipment having a minimum axle load of 10 tons (e.g. fully loaded tandem-axle dump truck). The areas subject to proofrolling should be traversed by the equipment in two perpendicular (orthogonal) directions with overlapping passes of the vehicle under the observation of the Geotechnical Engineer or authorized representative. This procedure is intended to assist in identifying any localized yielding materials. In the event that unstable or “pumping” subgrade is identified by the proofrolling, those areas should be marked for repair prior to the placement of any subsequent structural fill or other construction materials. Methods of repair of unstable subgrade, such as undercutting or moisture conditioning or chemical stabilization, should be discussed with the Geotechnical Engineer to determine the appropriate procedure with regard to the existing conditions causing the instability. Test pits may be excavated to explore the shallow subsurface materials in the area of the instability to help in determined the cause of the observed unstable materials and to assist in the evaluation of the appropriate remedial action to stabilize the subgrade. The roots/organics present at select locations could cause cracks during the design life of the tennis courts depending on subgrade preparation. 5.1.2 Subgrade Stabilization Subgrade Compaction: Upon completion of subgrade documentation, the exposed subgrade within the 5-foot expanded tennis court limits should be moisture conditioned to within -3 and +3 % of the soil’s optimum moisture content and be compacted with suitable equipment (minimum 10-ton roller) to a depth of at least 10 inches. Subgrade compaction within the pavement limits should be to a dry density of at least 95% of the standard Proctor maximum dry density (ASTM D698). ECS should be called on to document that proper subgrade compaction has been achieved. Subgrade Compaction Control: The expanded limits of the proposed construction areas should be well defined, including the limits for pavements. Field density testing of subgrades will be performed at frequencies in Table 5.1.2.1.
Table 5.1.2.1 Frequency of Subgrade Compaction Testing
Location Frequency of Tests
Tennis Court Areas 1 test per 10,000 sq. ft.
South Brunswick High School Tennis Courts November 5, 2018 ECS Project No. 22:27217 Page 9
5.2 EARTHWORK OPERATIONS
5.2.1 Structural Fill Materials Product Submittals: Prior to placement of structural fill, representative bulk samples (about 50 pounds) of on-site and off-site borrow should be submitted to ECS for laboratory testing, which will include Atterberg limits, natural moisture content, grain-size distribution, and moisture-density relationships for compaction. Import materials should be tested prior to being hauled to the site to determine if they meet project specifications. Satisfactory Structural Fill Materials: Materials satisfactory for use as structural fill should consist of inorganic soils classified as SM, SW, SP, GW, GP, GM and GC, or a combination of these group symbols, per ASTM D 2487. Natural fine-grained soils classified as clays or silts (CL, ML) should generally not be considered for use as engineered fill, but may be evaluated by the geotechnical engineer to determine their suitability at the contractor’s request. The materials should be free of organic matter, debris, and should contain no particle sizes greater than 4 inches in the largest dimension. Open graded materials, such as gravels (GW and GP), which contain void space in their mass should not be used in structural fills unless properly encapsulated with filter fabric. Suitable structural fill material should have the index properties shown in Table 5.2.1.1.
Table 5.2.1.1 Structural Fill Index Properties
Location with Respect to Final Grade LL PI % Passing #200 Sieve
Tennis Court Areas 20 max 9 max 35
Unsatisfactory Materials: Materials that should not be used as engineered fill include topsoil, organic materials (OH, OL), and high plasticity clays and silts (CH, MH). Such materials removed during grading operations should be either stockpiled for later use in landscape fills, or placed in approved on or off-site disposal areas. Satisfactory Materials: Near surface sands (SM, SM-SP) should be considered suitable for reuse as structural fill. Moisture conditioning of the soils is anticipated. 5.2.2 Compaction Structural Fill Compaction: Structural fill within the expanded tennis court limits should be placed in maximum 8-inch loose lifts, moisture conditioned as necessary to within -3 and +3 % of the soil’s optimum moisture content, and be compacted with suitable equipment to a dry density of at least 95% of the standard Proctor maximum dry density (ASTM D698). In non-structural areas, compaction of at least 90% should be achieved. ECS should be called on to document that proper fill compaction has been achieved.
South Brunswick High School Tennis Courts November 5, 2018 ECS Project No. 22:27217 Page 10
Fill Compaction Control: The expanded limits of the proposed construction areas should be well defined, including the limits of the fill zones for pavements, and slopes, etc., at the time of fill placement. Grade controls should be maintained throughout the filling operations. All filling operations should be observed on a full-time basis by a qualified representative of the construction testing laboratory to determine that the minimum compaction requirements are being achieved. Field density testing of fills will be performed at the frequencies shown in Table 5.2.3.1, but not less than 1 test per lift.
Table 5.2.3.1 Frequency of Compaction Tests in Fill Areas
Location Frequency of Tests
Pavement Areas 1 test per 10,000 sq. ft. per lift
Utility Trenches 1 test per 200 linear ft. per lift
Compaction Equipment: Compaction equipment suitable to the soil type being compacted should be used to compact the subgrades and fill materials. Sheepsfoot compaction equipment should be suitable for the fine-grained soils (Clays and Silts). A vibratory steel drum roller should be used for compaction of coarse-grained soils (Sands) as well as for sealing compacted surfaces. Fill Placement Considerations: Fill materials should not be placed on frozen soils, on frost-heaved soils, and/or on excessively wet soils. Borrow fill materials should not contain frozen materials at the time of placement, and all frozen or frost-heaved soils should be removed prior to placement of Structural Fill or other fill soils and aggregates. Excessively wet soils or aggregates should be scarified, aerated, and moisture conditioned.
At the end of each work day, all fill areas should be graded to facilitate drainage of any precipitation and the surface should be sealed by use of a smooth-drum roller to limit infiltration of surface water. During placement and compaction of new fill at the beginning of each workday, the Contractor may need to scarify existing subgrades to a depth on the order of 4 inches so that a weak plane will not be formed between the new fill and the existing subgrade soils. Drying and compaction of wet soils is typically difficult during the cold, winter months. Accordingly, earthwork should be performed during the warmer, drier times of the year, if practical. Proper drainage should be maintained during the earthwork phases of construction to prevent ponding of water which has a tendency to degrade subgrade soils. Where fill materials will be placed to widen existing embankment fills, or placed up against sloping ground, the soil subgrade should be scarified and the new fill benched or keyed into the existing material. Fill material should be placed in horizontal lifts. In confined areas such as utility trenches, portable compaction equipment and thin lifts of 3 inches to 4 inches may be required to achieve specified degrees of compaction. We recommend that the grading contractor have equipment on site during earthwork for both drying and wetting fill soils. We do not anticipate significant problems in controlling moisture within the fill during dry weather, but moisture control may be difficult during winter months or extended periods of rain. The control of moisture content of higher plasticity soils is difficult when these soils become wet. Further, such soils are easily degraded by construction traffic when the moisture content is elevated.
South Brunswick High School Tennis Courts November 5, 2018 ECS Project No. 22:27217 Page 11
5.3 GENERAL CONSTRUCTION CONSIDERATIONS
Moisture Conditioning: During the cooler and wetter periods of the year, delays and additional costs should be anticipated. At these times, reduction of soil moisture may need to be accomplished by a combination of mechanical manipulation and the use of chemical additives, such as lime or cement, in order to lower moisture contents to levels appropriate for compaction. Alternatively, during the drier times of the year, such as the summer months, moisture may need to be added to the soil to provide adequate moisture for successful compaction according to the project requirements. Subgrade Protection: Measures should also be taken to limit site disturbance, especially from rubber-tired heavy construction equipment, and to control and remove surface water from development areas, including structural and pavement areas. It would be advisable to designate a haul road and construction staging area to limit the areas of disturbance and to prevent construction traffic from excessively degrading sensitive subgrade soils and existing pavement areas. Haul roads and construction staging areas could be covered with excess depths of aggregate to protect those subgrades. The aggregate can later be removed and used in pavement areas. Surface Drainage: Surface drainage conditions should be properly maintained. Surface water should be directed away from the construction area, and the work area should be sloped away from the construction area at a gradient of 1 percent or greater to reduce the potential of ponding water and the subsequent saturation of the surface soils. At the end of each work day, the subgrade soils should be sealed by rolling the surface with a smooth drum roller to minimize infiltration of surface water.

APPENDIX C – Supplemental Report Documents
GBA Document
Geotechnical-Engineering ReportImportant Information about This
Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes.
While you cannot eliminate all such risks, you can manage them. The following information is provided to help.
The Geoprofessional Business Association (GBA) has prepared this advisory to help you – assumedly a client representative – interpret and apply this geotechnical-engineering report as effectively as possible. In that way, clients can benefit from a lowered exposure to the subsurface problems that, for decades, have been a principal cause of construction delays, cost overruns, claims, and disputes. If you have questions or want more information about any of the issues discussed below, contact your GBA-member geotechnical engineer. Active involvement in the Geoprofessional Business Association exposes geotechnical engineers to a wide array of risk-confrontation techniques that can be of genuine benefit for everyone involved with a construction project.
Geotechnical-Engineering Services Are Performed for Specific Purposes, Persons, and ProjectsGeotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical-engineering study conducted for a given civil engineer will not likely meet the needs of a civil-works constructor or even a different civil engineer. Because each geotechnical-engineering study is unique, each geotechnical-engineering report is unique, prepared solely for the client. Those who rely on a geotechnical-engineering report prepared for a different client can be seriously misled. No one except authorized client representatives should rely on this geotechnical-engineering report without first conferring with the geotechnical engineer who prepared it. And no one – not even you – should apply this report for any purpose or project except the one originally contemplated.
Read this Report in FullCostly problems have occurred because those relying on a geotechnical-engineering report did not read it in its entirety. Do not rely on an executive summary. Do not read selected elements only. Read this report in full.
You Need to Inform Your Geotechnical Engineer about ChangeYour geotechnical engineer considered unique, project-specific factors when designing the study behind this report and developing the confirmation-dependent recommendations the report conveys. A few typical factors include: • the client’s goals, objectives, budget, schedule, and risk-management preferences; • the general nature of the structure involved, its size, configuration, and performance criteria; • the structure’s location and orientation on the site; and • other planned or existing site improvements, such as retaining walls, access roads, parking lots, and underground utilities.
Typical changes that could erode the reliability of this report include those that affect:• the site’s size or shape;• the function of the proposed structure, as when it’s changed from a parking garage to an office building, or from a light-industrial plant to a refrigerated warehouse;• the elevation, configuration, location, orientation, or weight of the proposed structure;• the composition of the design team; or• project ownership.
As a general rule, always inform your geotechnical engineer of project changes – even minor ones – and request an assessment of their impact. The geotechnical engineer who prepared this report cannot accept responsibility or liability for problems that arise because the geotechnical engineer was not informed about developments the engineer otherwise would have considered.
This Report May Not Be ReliableDo not rely on this report if your geotechnical engineer prepared it:• for a different client;• for a different project;• for a different site (that may or may not include all or a portion of the original site); or • before important events occurred at the site or adjacent to it; e.g., man-made events like construction or environmental remediation, or natural events like floods, droughts, earthquakes, or groundwater fluctuations.
Note, too, that it could be unwise to rely on a geotechnical-engineering report whose reliability may have been affected by the passage of time, because of factors like changed subsurface conditions; new or modified codes, standards, or regulations; or new techniques or tools. If your geotechnical engineer has not indicated an “apply-by” date on the report, ask what it should be, and, in general, if you are the least bit uncertain about the continued reliability of this report, contact your geotechnical engineer before applying it. A minor amount of additional testing or analysis – if any is required at all – could prevent major problems.
Most of the “Findings” Related in This Report Are Professional OpinionsBefore construction begins, geotechnical engineers explore a site’s subsurface through various sampling and testing procedures. Geotechnical engineers can observe actual subsurface conditions only at those specific locations where sampling and testing were performed. The data derived from that sampling and testing were reviewed by your geotechnical engineer, who then applied professional judgment to form opinions about subsurface conditions throughout the site. Actual sitewide-subsurface conditions may differ – maybe significantly – from those indicated in this report. Confront that risk by retaining your geotechnical engineer to serve on the design team from project start to project finish, so the individual can provide informed guidance quickly, whenever needed.
This Report’s Recommendations Are Confirmation-DependentThe recommendations included in this report – including any options or alternatives – are confirmation-dependent. In other words, they are not final, because the geotechnical engineer who developed them relied heavily on judgment and opinion to do so. Your geotechnical engineer can finalize the recommendations only after observing actual subsurface conditions revealed during construction. If through observation your geotechnical engineer confirms that the conditions assumed to exist actually do exist, the recommendations can be relied upon, assuming no other changes have occurred. The geotechnical engineer who prepared this report cannot assume responsibility or liability for confirmation-dependent recommendations if you fail to retain that engineer to perform construction observation.
This Report Could Be MisinterpretedOther design professionals’ misinterpretation of geotechnical-engineering reports has resulted in costly problems. Confront that risk by having your geotechnical engineer serve as a full-time member of the design team, to: • confer with other design-team members, • help develop specifications, • review pertinent elements of other design professionals’ plans and specifications, and • be on hand quickly whenever geotechnical-engineering guidance is needed. You should also confront the risk of constructors misinterpreting this report. Do so by retaining your geotechnical engineer to participate in prebid and preconstruction conferences and to perform construction observation.
Give Constructors a Complete Report and GuidanceSome owners and design professionals mistakenly believe they can shift unanticipated-subsurface-conditions liability to constructors by limiting the information they provide for bid preparation. To help prevent the costly, contentious problems this practice has caused, include the complete geotechnical-engineering report, along with any attachments or appendices, with your contract documents, but be certain to note conspicuously that you’ve included the material for informational purposes only. To avoid misunderstanding, you may also want to note that “informational purposes” means constructors have no right to rely on the interpretations, opinions, conclusions, or recommendations in the report, but they may rely on the factual data relative to the specific times, locations, and depths/elevations referenced. Be certain that constructors know they may learn about specific project requirements, including options selected from the report, only from the design drawings and specifications. Remind constructors that they may
perform their own studies if they want to, and be sure to allow enough time to permit them to do so. Only then might you be in a position to give constructors the information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Conducting prebid and preconstruction conferences can also be valuable in this respect.
Read Responsibility Provisions CloselySome client representatives, design professionals, and constructors do not realize that geotechnical engineering is far less exact than other engineering disciplines. That lack of understanding has nurtured unrealistic expectations that have resulted in disappointments, delays, cost overruns, claims, and disputes. To confront that risk, geotechnical engineers commonly include explanatory provisions in their reports. Sometimes labeled “limitations,” many of these provisions indicate where geotechnical engineers’ responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly.
Geoenvironmental Concerns Are Not CoveredThe personnel, equipment, and techniques used to perform an environmental study – e.g., a “phase-one” or “phase-two” environmental site assessment – differ significantly from those used to perform a geotechnical-engineering study. For that reason, a geotechnical-engineering report does not usually relate any environmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated subsurface environmental problems have led to project failures. If you have not yet obtained your own environmental information, ask your geotechnical consultant for risk-management guidance. As a general rule, do not rely on an environmental report prepared for a different client, site, or project, or that is more than six months old.
Obtain Professional Assistance to Deal with Moisture Infiltration and MoldWhile your geotechnical engineer may have addressed groundwater, water infiltration, or similar issues in this report, none of the engineer’s services were designed, conducted, or intended to prevent uncontrolled migration of moisture – including water vapor – from the soil through building slabs and walls and into the building interior, where it can cause mold growth and material-performance deficiencies. Accordingly, proper implementation of the geotechnical engineer’s recommendations will not of itself be sufficient to prevent moisture infiltration. Confront the risk of moisture infiltration by including building-envelope or mold specialists on the design team. Geotechnical engineers are not building-envelope or mold specialists.
