10 SECTION 2. WORK STATEMENT
Project Understanding
The Vista Canyon Bridge and Road Improvements
project will construct a new two-lane roadway and
bridge over the Santa Clara River. The new roadway and
bridge will connect Soledad Canyon Road, located north
of the river and Antelope Valley Freeway (State Route
14), to the new Vista Canyon Ranch community, south
of the river. Although the bridge is a major component
of the project, the roadway improvements make up a
significant part of the project. The Vista Canyon Bridge project has been in the planning and development
phase for several years and is being driven by the Vista Ranch Community development in the area south
of the bridge. The final design and construction were
originally the responsibility of others, but the City recently assumed control of the project delivery to move the
project forward in a more timely manner. This City will be administering the project through construction.
The bridge structure is 64 feet, 9 inches wide by 781 feet, 2 inches long with nine spans consisting of a reinforced concrete deck placed over pre-cast/pre-stressed
girders, which span between eight bridge piers and
abutments at the embankments on either end of the
bridge. The bridge piers each consist of a bent cap
supported by three 54-inch diameter columns, and
the foundation of each column is a 96-inch diameter
cast-in-drilled-hole concrete (CIDH) pile extending
approximately 80 feet below the existing ground
surface. The abutments at either end of the bridge are
supported by driven steel pile foundations and will be
protected with rock slope stabilization. Traffic features of the bridge include one lane in each direction with
a striped median for emergency vehicles, highway
safety lighting, concrete barriers, metal railing, a raised landscape planter, a sidewalk with a Class 1 bike lane, and a new bike trail under the bridge. Construction of
the bridge also includes architectural treatments such
as a concrete barrier relief pattern (to match other city bridges) and a bid option for concrete pilasters with
drystack pattern surface texture and Vista Canyon logo.
The bridge will also carry a 16-inch waterline requiring coordination with Santa Clarita Valley Water District.
The project is being constructed in an environmentally
sensitive area involving several permits including the
US Army Corp of Engineers, California Fish and Wildlife, and the Los Angeles Regional Water Quality Control
Board. The Construction Management team will need to
coordinate with the City’s environmental consultant and project biologist to ensure the contractor is complying with all permit requirements. Construction of the bridge will be influenced by the multiple approval conditions
of the various permits governing the work within the
limits of the Santa Clara River. The project will also
require coordination with Caltrans and the County of
Los Angeles as portions of the project will encroach into Caltrans and County right-of-way.
The project will also provide improvements to
Soledad Canyon Road to the north of the bridge and
will construct improvements south of the bridge to
Humphreys Parkway as well as a small portion of the
existing Vista Canyon Boulevard to connect into the Vista Ranch Community connection. The improvements at
the Soledad Canyon Road and Vista Canyon Boulevard
include a new traffic signal, new exclusive eastbound
left-turn and right-turn lane additions, a lane extension of the existing westbound left-turn lane, removal and
replacement of median landscape and hardscape,
paving, curb and gutter, signing and striping, roadway
widening along the future Vista Canyon Boulevard,
installation of American with Disabilities Act (ADA)
ramps, removal of street lights, demolition of existing conflicting facilities, utility installation and relocations, and new sidewalk. The improvements at Vista Ranch
Community connection include the construction of a
new traffic roundabout, curb and gutter, paving, signing and striping, sidewalk, and utility connections and
connections to the existing bike paths along either bank of the river. The new bridge and its associated bridge
connecting Soledad Canyon with the Vista Canyon
Ranch community will create a substantial improvement
in circulation throughout the region and provide direct access to the Vista Canyon Metrolink and Bus Transfer
Station, businesses, residences, and other communities
south of the Santa Clara River and State Route 14
freeway.
Critical Elements
CIDH Pile Construction
A critical item of work with the potential to impact
the project schedule is the placement of the
Section 2. Work Statement2
11 SECTION 2. WORK STATEMENT
96-inch diameter CIDH piles. Placement of the piles will require rigorous planning and inspection due to the
geotechnical site conditions, environmentally sensitive area, potentially running water, and complex nature of
constructing CIDH piles within a river. Groundwater is
anticipated in all the piles and will require placing the pile concrete under the slurry via a tremie tube. Working within the Santa Clara River will require the contractor to manage their operation and sequence their work to
conform with the environmental permit requirements.
Laydown area, disposal of spoils, and control of water
displacement will need to be evaluated prior to approval of the contractor’s pile installation plan. The contract bid alternate for construction of the bridge pilasters also includes the use of 72-inch diameter CIDH piles under
similar conditions.
In addition to reviewing the contractor’s pile installation plan, MNS will hold a CIDH pile pre-construction meeting and carefully monitor quality control procedures
required for CIDH pile construction. Our team has
extensive experience reviewing the required CIDH pile
submittals including the contractor’s pile concrete
mix design (with unique slump requirements), pile
installation plan, resistance butt-welded splice
prequalification report, inspection pipe and reinforcing cage coupler log, concrete placement log, temporary
rebar cage support system shop drawings and design
calculations, and possible mitigation plans and
reports. MNS will ensure that the contractor follows and meets the quality control requirements for CIDH pile
construction including test batch and pre-qualification testing for the high slump concrete mix design, and
resistance butt-welded splice testing.
Care needs to be taken with this operation to prevent
contamination of the piles and project delays due to
defective pile construction. Final acceptance will be
based on gamma-gamma testing to verify the density
of the pile concrete. If an anomaly is discovered in
the piles, it will need to be mitigated by the contractor which can take significant time and effort and greatly
impact the schedule, especially with the large number
of piles on this project. The piles are one of the biggest risk factors to completing the work within the allocated working window.
MNS and more specifically our Resident Engineer/
Structure Representative, Dean Russu, PE, QSD/QSP,
and Assistant Structure Representative/Construction
Inspector, John Spalione, PE, have extensive experience overseeing the construction of CIDH piles in wet
conditions and very challenging, environmentally
sensitive locations under varying conditions, including expediting diagnosis and repair of anomalies that may
result from improper pile placement.
The Castroville Overhead Bridge Widening, Union
Road Bridge, Estrella River Bridge Rehabilitation, and
the Geneseo Road Bridge projects involved CIDH piles
installed in locations that encountered water at the creek bed level. MNS inspected the installation of permanent
and temporary casing, the use of polymer slurry, and the ultimate gamma-gamma testing of these piles. MNS has
an extensive and proven record of working closely with
the contractor and designer to successfully expedite
the repair and mitigation of anomalies found in large-
diameter CIDH piles and thereby avoiding potentially
large delays to the construction schedule.
Compliance with Environmental
Permits
Key biological resource issues for the project
include impacts to the bank and channel of the
Santa Clara River, sensitive riparian habitat, and special- status wildlife species. Special-status wildlife species that could occur at the site include the three-spine
stickleback (fish), white-tail kite, western spadefoot
(toad), and Crotches bumble bee. The team will utilize
the National Environmental Policy Act (NEPA) and
California Environmental Quality Act (CEQA) Initial Study/ Mitigated Negative Declaration (IS/MND) documents
along with the California Department of Fish and Wildlife (CDFW), United States Army Corps of Engineers (USACE)
and Regional Water Quality Control Board (RWQCB)
permits to provide mitigation and protection to the
protected species identified on the project site.
MNS has managed projects with similar significant
environmental considerations, such as the Union Road
Bridge Replacement, Hospital Road Bridge Low Water
Crossing Replacement, McHenry Avenue Corridor
Improvements, and Geneseo Road Low Water Bridge
Replacement projects. In our experience, the language
in such permits is often ambiguous and places
responsibility upon the permit holder, as opposed to the contractor, to perform the required tasks to comply with the permit requirements; it is not written in a manner
to serve as a clear and enforceable specification. For
example, permits usually include language such as
“the permittee should,” which leaves the bidders with
questions regarding interpretation.
Our approach is to review the permits carefully with
the project environmental consultant to generate
a list of specific requirements for each permit and
12 SECTION 2. WORK STATEMENT
identify which requirements will be the responsibility
of the permittee or project biologist, and which will
be delegated to the contractor. Upon identifying the
specific requirements, we will incorporate these in
our environmental management tracking process.
Additionally, we will coordinate closely with the City
furnished biologist to resolve any permit issues and to ensure that required surveys and reporting requirements are performed in a timely manner in order to maintain
continual compliance with the permits. Keeping the
contractor and project staff aware of the various permit requirements will begin in the pre-construction phase
with a permit kick-off meeting. Pre-construction surveys of environmentally sensitive species will need to be
taken before any clearing and grubbing operation as
well as work within the channel area. It is important
the contractor include consideration of any permit
conditions and allowable working windows for various
activities in their baseline schedule.
Stormwater Pollution Control is another important
element of the project. Our team includes certified QSP and QSD staff to ensure the project’s compliance with
the approved SWPPP and Water Pollution Control Board
401 permit. MNS Construction Inspectors will provide
focused attention to dust control, prevention of sediment tracking onto the roadway, and site maintenance.
The CIDH pile operations have the potential to require
dewatering which would require special consideration of the dewatering conditions of the permits that determine where and how the water can be discharged. Also,
since the environmental permits prohibit working within flowing or standing water the contractor may need
to construct a water diversion system and temporary
crossing over the channel area to access both sides
of the creek. Dean Russu, PE, QSD/QSP, will assist our
SWPPP Specialist, Craig Snell, QSD/QSP, CPESC, with
SWPPP review and inspections as well as monitoring of
the contractor’s water sampling, testing and reporting, as well as enforce the water-related conditions of the
environmental permits.
Utility Facilities
An extensive array of various underground, pad-
mounted, and bridge-supported utility facilities
are identified in the project plans, including
Southern California Edison electrical power service, City signals and bridge lighting, telecommunications lines,
fiber optic interconnects, water lines, irrigation, and irrigation controls. Effective coordination and timely
installation of new configurations or relocation of existing utilities will be critical to the overall progress of the work.
Although the City has utility agreements with the various individual companies involved, and the facilities will
be installed according to the provision of the contract, the City will have limited control over the timing of
inspections, acceptance and connection services of the
third-party utility providers. Therefore, there is a risk to the City of utilities not being relocated within the time allocated in the Special Provisions.
Utility work, if not managed and coordinated in a
proactive manner, may cause delays to project
completion resulting in claims for additional
compensation from the contractor and potential
additional cost to the City. Utility delays may also extend the completion of the project, thus impacting the local residential and business communities.
The key to minimizing the risk of delays to the Project is to manage the installation of utilities proactively. We will accomplish this by holding initial utility coordination meetings immediately after receiving our Notice
to Proceed from the City with representatives from
each utility company with work on the Project. We will
establish relationships, review the overall project and the preliminary project schedule, and discuss how the work
of each utility company will interface with each other
and the work of the contractor. During each meeting,
we will work toward developing a commitment by
the utility representatives to support the needs of the Project. We will also develop a clear understanding of
any constraints, concerns, or issues, and any measures
or action required on our part to address or work around these issues.
After the initial meetings, it will be critical to keep this Project on the utility companies’ radar to ensure the
needs of this project are not forgotten. The MNS team will accomplish this by holding regularly scheduled utility
coordination meetings with the contractor and the utility companies performing relocation work on the Project.
These meetings will update the utility companies on
the progress of the work and when their work will need
to be performed to ensure work crews are scheduled
when needed; any potential issues will be raised and
addressed sufficiently in advance of the required work.
Pre-cast/Pre-stressed (PC/PS)
Concrete Girders
The Project involves a large amount of PC/
PS girders, which the fabrication and placement will
be critical to meeting the project schedule. To ensure
the PC/PS concrete girders are ready for installation
upon completion of the bridge piers, it is imperative the 13 SECTION 2. WORK STATEMENT
contractor begins the fabrication process immediately
upon award of the contract. Fabrication and installation of the girders is a long lead item and any delay in the process may result in a significant impact the project
schedule. The MNS CM team is intimately familiar with
proactively managing the multi-step process of shop
drawing review, girder production, quality assurance and source inspection, and planning the installation girders in coordination with the construction of the bridge piers.
The first step in the production process is the submittal of the contractor’s proposed shop drawings. MNS will
work closely with the project design team, Dokken
Engineering, and our source inspection team ZT
Consulting (ZTC) on the review of the shop drawings
for compliance with the contract documents. Primary
considerations in the review of the shop drawings
include verification of proposed girder dimensions,
camber calculations, concrete mix design, pre-stressing strand profiles, and calculations of jacking forces and strand elongations. We have found that shop drawings
may go through several iterations before they are in a
condition to be approved. Therefore, MNS is committed
to expediting the CM/Designer review and coordinating
directly with the girder fabricator in order to mitigate any potential delays in the approval process.
During the production of the PC/PS concrete girders
our source inspection subconsultant, ZTC, will be
continually on-site at the fabrication facility performing inspection of the many facets of girder construction
including inspection of form dimensions, girder camber, rebar placement and pre-stressing strand tolerances,
concrete quality, strength, and curing times, calculation and monitoring of pre-stressing forces and strand
elongations. All inspection records will be compiled and verified to document the acceptance of the girders for
use in the work of the contract.
Only upon verification of the quality assurance testing and source inspection documents will the girders be
tagged and released for delivery to the project site. It is important to monitor and control the camber of the
girders at the fabrication yard as excessive camber
may affect the grading of the deck. The contractor’s
camber control method needs to be included in the
shop drawing and/or girder placement plan. It is the
MNS management approach to provide the services
described above in a timely manner and to work in
close coordination with the contractor to ensure the
successful planning, production and installation of the PC/PS concrete girders.
Scope of Work
MNS has tailored a scope of work to provide
comprehensive construction management services to
meet the City’s scope of work requirements for the Vista Canyon Bridge Project. The MNS RE will work closely with the City’s Project Manager in managing the project. Due to budget constraints, MNS will work closely with City
staff in managing the project by utilizing City staff where needed. The technical approach provided herein has

If any additional Contract documents are executed, the actual Indemnity language and Insurance Requirements may include additional provisions as deemed appropriate by City’s Purchasing Agent.
b. You should check with your Insurance advisors to verify compliance and determine if additional coverage or limits may be needed to adequately insure your obligations under this agreement. These are the minimum required and do not in any way represent or imply that such coverage is sufficient to adequately cover the Contractor’s liability under this agreement. The full coverage and limits afforded under Contractor’s policies of Insurance shall be available to Buyer and these Insurance Requirements shall not in any way act to reduce coverage that is broader or includes higher limits than those required.
The Insurance obligations under this agreement shall be: 1—all the Insurance coverage and limits carried by or available to the Contractor; or 2 —the minimum Insurance requirements shown in this agreement, whichever is greater. Any insurance proceeds in excess of the specified minimum limits and coverage required, which are applicable to a given loss, shall be available to City.
c. Contractor shall furnish the City with original Certificates of Insurance including all required amendatory endorsements and a copy of the Declarations and Endorsement Page of the CGL policy listing all policy endorsements to City before work begins. City reserves the right to require full- certified copies of all Insurance coverage and endorsements.
3. INDEMNIFICATION
a. To the fullest extent permitted by law, CONSULTANT shall defend (with legal counsel reasonably acceptable to CITY), indemnify and hold harmless CITY and its officers, agents, departments, officials, representatives and employees (collectively “Indemnitees”) from and against any and all claims, loss, cost, damage, injury (including, without limitatio n, economic harm, injury to or death of an employee of CONSULTANT or its subconsultants), expense and liability of every kind, nature and description that arise B-6
APPENDIX B. FORMS
from or relate to (including, without limitation, incidental and consequential damages, court c osts, attorneys’ fees, litigation expenses and fees of expert consultants or expert witnesses incurred in connection therewith and costs of investigation) that arise from or relate to, directly or indirectly, in whole or in part, from: (1) CONSULTANT’s performance of Services under this Agreement, or any part thereof; (2) any negligent act or omission of CONSULTANT, any subconsultant, anyone directly or indirectly employed by them, or anyone that they control; (3) any actual or alleged infringement of the patent rights, copyright, trade secret, trade name, trademark, service mark or any other intellectual or proprietary right of any person or persons in consequence of the use by CITY, or any other Indemnitee, of articles or Services to be supplied in the pe rformance of this Agreement; or (4) any breach of this Agreement (collectively “Liabilities”). Such obligations to defend, hold harmless and indemnify any Indemnitee shall not apply to the extent such Liabilities are caused by the sole negligence or willf ul misconduct of such Indemnitee, but shall apply to all other Liabilities. The foregoing shall be subject to the limitations of California Civil Code section 2782.8 as to any design professional services performed by CONSULTANT and in particular the limi tation on CONSULTANT’s duty to defend whereby such duty only arises for claims relating to the negligence, recklessness or willful misconduct of CONSULTANT as well as the limitation on the cost to defend whereby CONSULTANT will only bear such cost in proportion to CONSULTANT’s proportionate percentage of fault (except as otherwise provided in section 2782.8).
b. The foregoing indemnification provisions will not reduce or affect other rights or obligations which would otherwise exist in favor of the CITY and other Indemnitees.
c. CONSULTANT shall place in its subconsulting agreements and cause its subconsultants to agree to indemnities and insurance obligations in favor of CITY and other Indemnitees in the exact form and substance of those contained in this Agreement.
4. INSURANCE
a. Before commencing performance under this Agre ement, and at all other times this Agreement is effective, CONSULTANT will procure and maintain the following types of insurance with coverage limits complying, at a minimum, with the limits set forth below:
Type of Insurance Limits
Commercial general liability: $1,000,000
Professional liability $1,000,000
Business automobile liability $1,000,000
Workers compensation Statutory requirement
b. Commercial general liability insurance will meet or exceed the requirements of ISO -CGL Form No. CG 00 01 11 85 or 88. The amount of insurance set forth above will be a combined single limit per occurrence for bodily injury, personal injury, and property damage for the policy coverage. Automobile coverage will be written on ISO Business Auto Coverage Form CA 00 01 06 92, including symbol 1 (Any Auto). Liability policies will be endorsed to name CITY, its officials, and employees as “additional insureds” under said insurance coverage and to state that such insurance will be deemed “primary” such that any other insurance that may be carried by CITY will be excess thereto. Such endorsement must be reflected on ISO Form No. CG 20 10 11 85 or 88, or equivalent. Such insurance will be on an “occurrence,” not a “claims B-7

made,” basis and will not be cancelable or subject to reduction except upon thirty (30) days prior written notice to CITY.
c. Professional liability coverage will be on an “occurrence basis” if such coverage is available, or on a “claims made” basis if not available. When coverage is provided on a “claims made basis,” CONSULTANT will continue to renew the insurance for a period of at least three (3) years after this Agreement expires or is terminated. Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover CONSULTANT for all claims made by CITY arising out of any errors or omissions of CONSULTANT, or its officers, employees or agents during the time this Agreement was in effect.
d. CONSULTANT will furnish to CITY duly authenticated Certificates of Insurance evidencing maintenance of the insurance required under this Agreement, including endorsements, and such other evidence of insurance or copies of policies as may be reasonably required by CITY from time to time. Insurance must be placed with California-admitted insurers with (other than workers compensation) a current A.M. Best Company Rating of at least “A:VII.”
e. Waiver of Subrogation: The insurer(s) agree to waive all rights of subrogation against CITY, its elected or appointed officers, officials, agents, volunteers and employees for losses paid under the terms of the workers compensation policy which arise from work performed by CONSULTANT for CITY.
f. Should CONSULTANT, for any reason, fail to obtain and maintain the insurance required by this Agreement, CITY may obtain such coverage at CONSULTANT’s expense and deduct the cost of such insurance from payments due to CONSULTANT under this Agreement or terminate pursuant to TERMINATION section. In the alternative, should CONSULTANT fail to meet any of the insurance requirements under this Agreement, City may terminate this Agreement immediately with no penalty.
g. Should CONSULTANT’S insurance required by this Agreement be cancelled at any point prior to expiration of the policy, CONSULTANT must notify City within 24 hours of receipt of notice of cancellation.
Furthermore, CONSULTANT must obtain replacement coverage that meets all contractual requirements within 10 days of the prior insurer’s issuance of notice of cancellat ion. CONSULTANT must ensure that there is no lapse in coverage.
h. The CITY shall be entitled to any coverage in excess of the minimums required herein.
I have read and understand the above requirements and agree to be bound by them for any work performed for the City.

Attachment: 2024 Fee Schedule
NV5 West, Inc. appreciates the opportunity to be of service. If you have any questions, please do not hesitate to contact us.
Inspection and testing callouts will be 2, 4, 6 or 8 hour minimum daily charges.
Our services will be provided on an on-call basis at the direction of the MNS Engineers, Inc. (MNS). Since NV5 does not control the contractor's schedule, cost estimates given prior to the beginning of construction are made in good faith based on our experience with similar projects. Our estimates may not coincide with the actual construction duration or contractors productivity, nor reflect the final scope of our work. MNS staff will have control over the frequency of our site visits and testing, and ultimately the fee for our services.
Estimated inspection and testing time includes round-trip travel to site. Field time is billed portal to portal from our Ventura office. For this project, travel time is estimated to be 50 minutes each way.
Assumptions:
Prevailing Wage and Overtime Rates Apply if applicable.

Attention: Mr. Greg Chelini
Proposal for Gamma-Gamma Logging (GGL)
CIDH Piles at Piers 2 through 9 and at Abutments 1 and 10 Pilasters Santa Clara River Bridge at Vista Canyon Boulevard
Santa Clarita, California
EarthSpectives (ES) is pleased to submit this proposal to provi de GGL of up to 28 CIDH piles at the subject project site. This proposal is based on project background information provided below:
- GGL to address 4 # 73” diameter shafts with an approximately length of 26 ft at Abutments 1&10 Pilasters, - GGL to address 3 # 96” diameter shafts with an approximately length of 76 ft at Pier 2, - GGL to address 12 # 96” diameter shafts with an approximately length of 68 ft at Piers 3, 4, 5, and 6, - GGL to address 6 # 96” diameter shafts with an approximately length of 67 ft at Piers 7 and 8, - GGL to address 3 # 96” diameter shafts with an approximately length of 70 ft at Pier 9, - Construction schedule requiring testing in up to 10 sessions (assumed).
We understand that 6 and 9 access tubes w ill be installed over the full length of each 72” and 96” piles. The depths given above combined with the number of inspection tubes considered lead to a presumed total quantity of 15528 ft of gamma-gamma tube logging. The access tubes consi st of 2-inch diameter Schedule 40 PVC pipes attached to the reinforcing cage.
We also understand that all shafts and tubes scheduled to be te sted within a given testing session will be safely accessible. Testing is to be performed according to Cali fornia Test Method CT233 Standards. GGL Testing includes lowering of 4.6 ft long and 1.25 in diameter p robe to the bottom of each inspection tube and measuring the density of the concrete in close proximity of the inspection tubes at 0.1 ft intervals along the full length of the pile. We do not anticipate providing geotechnical consultation beyond that related to your understanding of the testing methods utilized for the project.
Per your request, we propose to charge our services in accordance with the following unit costs:
- $ 950 per GGL move-in (includes equip. and operator mob, travel, mileage, accommodation, and set-up) - $ 2.00 per ft of gamma-gamma logging
- $ 50 per pile for data post processing
- $ 850 per GGL report at the end of each testing session
Although our total fee will vary according to the actual scope of work performed, present assumptions lead to a total estimate of approximately $50,456.00, as detailed below:
- 2 -
1 0 m o v e - i n s $950 x 10 = $ 9 , 500.00 15528 ft of tube gamma-gamma logging $2.0 x 15528 = $31,056.00 28 data post processing $50 x 28 = $ 1 , 400.00 1 0 r e p o r t s $850 x 10 = $ 8 , 500.00
T o t a l $50,456.00
Additional assumptions that were made to produce the above schedule of charges include the following:
- Shaft sites are safely accessible to vehicles,
- Access tubes provide unrestri cted access over their full leng th to probes, which has been checked prior to our arrival by others using a 1.25 inch diameter, 4.6 ft long dummy probe,
Our estimate does not include potential stand-by time due to potential lack of pile preparation, lack of access, pipe obstructions, or other reasons beyond our control, which will be charged at an hourly rate of $250 for field operations. Consultation regarding potential remedial action in case anomalies are identified can be made available at an hourly rate of $195. If anomalies are detected by GGL testing, it is sometimes beneficial to perform Cross-hole Sonic Logging (CSL) to further investigate t he nature and the extent of the anomalies identified by GGL. For this, we recommend a contingency of 25% to cover the potential need for CSL testing.
CSL testing will be charged in accordance with the following unit rates:
- $ 950 per CSL move-in (includes equip. and operator mob, travel, mileage, accommodation, and set-up) - $ 100.00 per CSL Profile including data post processing (15 and 36 profiles required for each 72” & 96” pile) - $ 850 per CSL report at the end of each testing session
We will mobilize within 3 business days of receiving your written authorization to proceed. However scheduling of appropriate resources will require advance notice of the approximate date of testing. Our test reports will be issued within 3 days of completed testing session.
We appreciate the opportunity to be of service to MNS. If you have any questions, in particular relating to our proposed scope and estimated fees, please call.
