PAS 128; Specification for underground utility detection, verification and lo...George Tuckwell
The new Publicly Available Standard from the British Standards Institute specifies the minimum that should be done in respect to underground utility detection, verification and location, and also provides guidance and pointers to best practice.
It sets out 4 types of survey: Desktop Study (Type D), site reconnaissance (Type C), detection (Type B), and verification (Type A).
The PAS supports both the practitioner and the client throughout the project cycle. At tender stage It is required for the practitioner to submit:
a) The survey type(s) to be deployed, including the extent for each type
b) For survey type B, detection methods to be deployed as specified in Table 2, including estimated extent for each method
c) Comment on these survey type(s) and, for survey type B, detection methods, with regard for satisfying the client’s requirements
d) Comments on the expected achievable quality level
e) Names and experience of the project team
f) How the survey area is to be managed to maximise the area available for survey and ensure the safe execution of the works
The client should then be able to compare apples with apples when seeking multiple quotes.
Following the work, the practitioner should submit a detailed report including:
• detailed survey outcomes including how successful each detection methodology proved to be and a plan showing any areas where these detection methodologies were not successful
• Utility segments identified with the quality level achieved
• Recommendation for any further survey work required to meet the client’s requirements
All recorded and processed data, site notes, metadata, and intermediate stage processing files shall be retained, and shall be available to the client on request
It is recommended as best practice for all data to be recorded as evidence of detections and of work undertaken. This is required where post processing has been specified. This is optional for other detection surveys – unless the client chooses to make it a requirement.
The practitioner needs to set out what they did and where, what the outcome was, i.e. what accuracy and confidence was achieved and what areas of uncertainty and risk remain. The practitioner should then stand by their deliverables.
If used properly by the client, the practitioner can no longer hide behind the ‘black box’ of complex geophysical equipment to explain away why something was missed or inaccurate in their survey output.
If adopted by the industry the PAS could enable:
• Clear definition for a minimum standard of utility verification and location
• More control to the client
• More comeback for the client when issues arise
• Fewer incidents related to service strikes
• Fewer delays caused by unknown buried services

MO3.L10 - STATUS OF PRE-LAUNCH ACTIVITIES FOR THE NPOESS COMMUNITY COLLABORAT...grssieee
The document summarizes the status of pre-launch validation activities for the NPP satellite. It discusses that validation teams are continuing work to characterize sensor data records and environmental data records in preparation for post-launch validation. Team leads provide experience from past missions and are working with stakeholders and experts to refine algorithms and calibration. Activities include analysis of test data, preparation of validation tools, and coordination between sensor and data record teams.
Remote geosteering provides consistent supervision more effectively and safely than conventional methods. It allows for 24/7 supervision from offsite locations to make real-time decisions. This improves safety, reduces costs, enhances data flow and communication. Remote geosteering is used for horizontal wells drilled close to reservoir contacts or zones, nighttime supervision, and combining multiple objectives. It involves continuous monitoring, assessing stratigraphic location, optimizing well placement, providing timeline estimates and reports. This standardized approach improves knowledge sharing and reduces costs through centralized resources and reporting.
This document summarizes a seismic survey project conducted near the Diablo Canyon Power Plant in California to image local faults. Fugro Consultants acquired both offshore and onshore 2D and 3D seismic reflection data under a Nuclear Quality Assurance program. Offshore, low-energy 3D surveys used P-Cable methodology. Onshore, surveys used vibroseis, accelerated weight drop, and nodal acquisition systems. Strict quality control was implemented during acquisition and processing to meet nuclear regulatory standards.
The document is a curriculum vitae for Sean Blanchette that summarizes his professional experience and qualifications. It details his education, survey equipment experience, software skills, and employment history working on various mining projects internationally from 1985 to the present day, including roles as a contract surveyor, senior project surveyor, and chief surveyor.
The document describes AquaLink, a proposed system to improve situational awareness for Navy divers. AquaLink would use buoys with GPS and satellite communication capabilities to provide divers and their support teams with location information and a communication channel to aid mission success. The document discusses initial prototypes, including a buoy with GPS and Iridium satellite communication that could be easily deployed and retrieved by divers.

Automating Semantic Metadata Collection in the Field with Mobile ApplicationDeborah McGuinness
Presentation at Mobile Deployment of Semantic Technologies Workshop at the International Semantic Web Conference. Abstract: In the past few decades, the field of ecology has grown from a collection of disparate researchers who collected data on their local phenomenon by hand, to large ecosystems-oriented projects partially fueled by automated sensor networks and a diversity of models and experiments. These modern projects rely on sharing and integrating data to answer questions of increasing scale and complexity. Interpreting and sharing the big data sets generated by these projects relies on information about how the data was collected and what the data is about, typically stored as metadata. Metadata ensures that the data can be interpreted and shared accurately and efficiently. Traditional paper-based metadata collection methods are slow, error-prone, and non-standardized, making data sharing difficult and inefficient. Semantic technologies offer opportunities for better data management in ecology, but also may pose a challenging learning curve to already busy researchers. This paper presents a mobile application for recording semantic metadata about sensor network deployments and experimental settings in real time, in the field, and without expecting prior knowledge of semantics from the users. This application enables more efficient and less error-prone in-situ metadata collection, and generates structured and shareable metadata.
Application-Oriented Bandwidth and Latency Aware Routing with OpenFlow NetworkPongsakorn U-chupala
Presentation at CloudCom'14
Abstract: Bandwidth and latency are two major factors that contribute the most to network application performance. Between each pair of switches in a network, there may be multiple paths connecting them. Each path has different properties because of multiple factors. Traditional shortest-path routing does not take this knowledge into consideration and may result in sub-optimal performance of applications and underutilization of network.We proposed a concept of “bandwidth and latency aware routing”. The idea is that we could improve overall performance of the network by separating application into bandwidth-oriented and latency-oriented application and allocate different route for each type of application accordingly. We also proposed a design of this network system implemented using OpenFlow. Routes are calculated from monitored information using Dijkstra algorithm and its variation. To support our design, we show a use case in which our design performs better than traditional routing as well as evaluation results.

The document summarizes a presentation about the development of the CSA S250 standard for mapping underground utilities. The standard aims to improve safety, reliability, and lower costs by specifying requirements for recording and depicting the location of underground infrastructure. It is expected to lead to improved decision making by promoting consistent, accurate utility maps that can be shared between stakeholders. The creation of the technical committee to develop the standard is discussed, along with some of its discussions around terminology, symbology, data sharing and accuracy levels.
Gregg Verutes gave a presentation on using geovisualization to convey coastal and marine research results to stakeholders. He discussed challenges with marine data and outlined tools to map coastal vulnerability and natural habitats' protection of coastlines. Examples from Belize showed mapping ecosystem services under scenarios. Lessons included ensuring tools and training supplement research. Next steps include modifying existing tools for Barbados and the Caribbean and providing marine spatial planning guidance and training.
The document provides information about Production Part Approval Process (PPAP). It discusses what PPAP is, its purpose, when it is required, benefits of PPAP submissions, elements of a PPAP submission including a production warrant, submission levels, and definitions of risk. Key points covered are that PPAP is used to reduce risks prior to product release, it provides evidence that requirements are understood and the process is capable of production, and it manages change and ensures product conformance.
The document provides an overview of Production Part Approval Process (PPAP) which is a standard used to formally reduce risks prior to product release. It was initially developed by the Auto Industry Action Group for the automotive industry. The purpose of PPAP is to provide evidence that customer requirements are understood and the process is capable of consistently producing parts that meet requirements. A PPAP submission is required when there are new parts, engineering changes, tooling changes, process changes, or supplier/material changes. It outlines the submission levels, requirements, and statuses. The Production Warrant is a key document in PPAP that confirms production parts meet customer requirements.
The document discusses VERIPOS' PPP-AR positioning service which provides centimeter-level global positioning using GNSS networks. PPP-AR offers faster initialization and reinitialization than traditional PPP, providing RTK-like accuracy globally. It works by estimating additional bias parameters to resolve carrier phase ambiguities. VERIPOS upgraded its infrastructure to support PPP-AR, including new reference stations and servers. PPP-AR demonstrates rapid reconvergence from signal outages, bridging gaps within seconds, making it suitable for applications where GNSS signals may be interrupted.
This presentation describes the principles of qualification and validation which are applicable to the facilities, equipment, utilities and processes used for the manufacture of medicinal products. It is a GMP requirement that manufacturer’s control the critical aspects of their particular operations through qualification and validation over the life cycle of the product and process. Any planned changes to the facilities, equipment, utilities and processes, which may affect the quality of the product, should be formally documented and the impact on the validated status or control strategy assessed.
This document summarizes the Nuclear Directorate's assessment of the control and instrumentation (C&I) systems for the proposed UK EPR nuclear reactor design. The assessment concluded that the C&I safety case was generally adequate but identified some issues requiring resolution. These issues related to diversifying safety systems, justifying network communications, and providing more detailed information on system reliability and displays. The Requesting Party addressed the issues to the regulator's satisfaction by providing additional safety case documentation and proposing design changes and future qualification plans. While some topics require further information, the C&I systems were found to be suitable subject to future assessment as more design details become available.
Geo Spatial Data And it’s Quality AssessmentIRJET Journal
This document discusses assessing the quality of geospatial data generated from unmanned aerial vehicle (UAV) images. The study area was approximately 5-6 km of the Banaras Hindu University campus in Varanasi, India. Images were captured using a DJI Mavic Pro Platinum drone and processed using ArcGIS Pro and Pix4dmapper to generate orthophotos, point clouds, and 3D models. The horizontal and vertical accuracies of the UAV solution were analyzed. Statistical analysis, including a paired t-test, showed the differences between UAV-derived data and reference GPS points were within acceptable limits of accuracy. The analysis demonstrated that accurate geospatial data can be produced from UAV images.
This document outlines a research study to understand existing and upcoming properties, customers, and service providers in specific locations. Key objectives are to profile the areas and understand customer awareness, perceptions, and loyalty regarding fiber internet and related services. The study will involve quantitative research through a structured questionnaire across 30 clusters in 3 areas, totaling 20,250 interviews. Deliverables will include location and customer profiling as well as service provider information. Fieldwork will take 10 days with daily progress reported. The estimated total cost is 175,000 rupees per cluster excluding taxes.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Thinkers/Inquiry • How has our ability to think and inquire helped to advance technology?
Vocabulary • Nature Deficit Disorder~ A condition that some people maintain is a spreading affliction especially affecting youth but also their adult counterparts, characterized by an excessive lack of familiarity with the outdoors and the natural world. • Precautionary Principle~ The approach whereby any possible risk associated with the introduction of a new technology is largely avoided, until a full understanding of its impact on health, environment and other areas is available.
What is technology? • Brainstorm a list of technology that you use everyday that your parents or grandparents did not have. • Compare your list with a partner.

What is a PAS?
A publicly available specification (PAS) is a sponsored fast-track standard.
It is written by a drafting panel and supported by a steering committee.
After two years, the PAS is reviewed and a decision is made as to whether it
should be taken forward to become a formal British Standard.

Aims of this PAS
PAS 128 aims to provide
Clarity on the service offered and the
methods employed
Consistency in the approach to data
capture
Classification of the results and the
confidence that can be associated
with them
Standardisation of the format of the
deliverables
Accountability for the work
undertaken.

Specification of minimum requirements
versus best practice guidance
Specification
The normative text sets out the minimum that must be done.
Best practice
The informative text provides guidance and also points to best practice.
This enables a range of responses to any request from a client. The client needs
to decide what specification they want and what contractual conditions they want
to put in place.

QL-D – Desk study
Identify the known utility owners
within the specified survey area.
Request asset information from the
identified utility owners.
Collate all the data on the utility
owners and their assets.

QL-C – Site reconnaissance
On-site checks shall document the
Presence, type and markings of utility-related
surface features
Measurements between known surface
features on the ground compared with those
depicted on the plan
Differences between the map/drawing or
digital features supplied and those extant on
the ground.

QL-B – Detection surveys
Use geophysical techniques to detect and identify the utilities
within the survey area.
The quality level (accuracy) achieved shall be documented as
QL-B1, QL-B2, QLB3 or QL-B4.
If post-processing has been used to improve the confidence
of the data, the quality level shall be suffixed with the letter ‘P’.

QL-A – Exposure and verification
Data shall be obtained through visual
inspection of the utility
At access points such as in a manhole
or inspection chamber, and/or
By its excavation and exposure.

Detection – Levels of effort and return
PAS 128 sets out guidance on the minimum effort required for different
situations.
For example, an urban area likely to be congested with multiple surveys would
be expected to require a more dense detection grid in order to detect utility
segments accurately.
It also makes clear that additional confidence and accuracy can be obtained by
post-processing the data:
This is done by taking the recorded geophysical data off-site, processing it in
3D volumes to enhance and isolate signals from buried utilities, and
transferring the results of that analysis onto detailed CAD drawings.

Transparency of work done – Deliverables
Retention of survey data/records
All recorded and processed data, site notes, metadata and intermediate-stage
processing files shall be retained and shall be available to the client on request
It is recommended as best practice for all data to be recorded as evidence of
detections and of work undertaken
This is required where post-processing has been specified
This is optional for other detection surveys – unless the client chooses to
make it a requirement.
14 November 2014 21

Accountability of results
In the deliverables, the practitioner must state
The quality level (level of accuracy) achieved for each segment of utility
identified and
Which detection techniques were used in all surveyed areas of the site,
including areas where no utilities have been detected.

Survey quality/accuracy and accountability
25. Copyright of RSK
Accountability of results
The client gets further protection if they specify that
All geophysical data are to be recorded and retained
Evidence is to be provided of the detections achieved and areas where
detections were impossible as part of the deliverables.
Benefits
Evidence is retained of the work done.
Data can be reviewed at a later date in the light of subsequent findings or as
part of a routine audit by the practitioner, the client or a third party.

Protection for the client
The practitioner needs to set out
What they did and where
What the outcome was, i.e.,
What accuracy and confidence were achieved
What areas of uncertainty and risk remain
What could additionally be done to reduce risk.
The practitioner should then stand by its product.
If PAS 128 is used properly by the client, the practitioner can no longer hide
behind a ‘black box’ of complex geophysical equipment to explain away why
something was missed or inaccurate in its survey output.

Take up
If adopted by the industry, PAS 128
could enable
Clear definition for a minimum
standard of utility verification and
location
More control for the client
More comeback for the client when
issues arise
Fewer incidents related to service
strikes
Fewer delays caused by unknown
buried services.
