The addition of two million square feet of new facilities and the demolition of deficient buildings will transform twelve sites. These new facilities, such as the Recreation Services Center at Palo Alto and the community Living Center at Menlo Park; new outpatient facilities in Modesto and Stockton, and replacement of Monterey, San Jose, Fremont and Stockton sites must be laser scanned to document the building structural and MEP systems for use in future maintenance, repair, and alterations. 1.2 Objective Each of these projects requires professional surveying services (done prior to wall closing after all Mechanical, electrical, and plumbing (MEP) is installed) to create an accurate as-built condition records to assist in maintenance, repair, and alterations throughout its lifespan. The 3D imaging must include TrueView 3D point cloud models. 1.3 Location All scanning work should be located throughout the Palo Alto Division (Northern California). 2.00 General Scope of Services 2.1 Pre-Survey Deliverables The following information shall be provided by the vendor in the project proposal: a)Technical specifications about the scanning system(s) to be used b)The proposed point density c)A description outlining causes of potential data voids and a proposed method for data collection in these areas. d)A Survey Method Statement which includes: i.Method and equipment used to establish control ii.Method and equipment used to establish coordinates of targets iii.Method proposed to access high areas. iv.Description of the targets to be used v.Method of registration 2.2 Certification Requirements Laser scanning systems used must be accompanied by a certificate confirming the system is working properly, or accompanied by details of tests performed in the last six (6) months that show the scanner achieves the required precision and accuracy. 2.3 Gathering Point Cloud Data 2.3.1 Weather Scanning/image capture should not be performed in adverse weather conditions where the quality of observed data may be affected. For example, scanning in heavy rain may lead to data voids due to falling raindrops and erroneous data points caused by returns from airborne raindrops or erroneous range measurement due to refraction of the measurement beam. 2.3.2 Point density and measurement precision a)Point accuracy required for the project is within 6mm in 3D at 50m range. Scanning system must capture 1mm point resolution at 200m range. b)Point resolution required for the project is based on the minimum feature required to be discernable in the point cloud, which is 2cm between points or otherwise stated. c)The beam width of the measurement beam must not be greater than double the effective point density. d)All references to point density will be provided as the average 3D distance between points at a defined range. 2.3.3 Overview and detail scans A combination of overview and detail scans provides both a clear description of the general scanned area in addition to providing detailed information of selected parts of a site or object. Detailed scans must be provided where all information is not captured in an overview scan. 2.3.4 Scan Timing Scans must be done prior to wall closing after all MEP is installed. 2.3.5 Overlapping scans Where it is acceptable, areas of overlapping scan data may be filtered to reduce the point density in the final registered point cloud and hence reduce file sizes and improve software performance/data handling during processing. This will be required to meet to the minimum point resolution requirement. 2.3.6 Data voids Data voids should be minimized during the scanning process through the strategic selection of scanning positions, using strategic procedures, scanning under appropriate weather conditions, and using multiple scans. Data voids due to temporary obstructions, such as those caused by vehicles and pedestrians, must be limited by scanner positioning or by restriction of such obstructions. 2.3.7 Access to high areas Laser scanning relies on a line of sight to a target and, therefore, where a subject of a significant height is to be surveyed; access to higher areas may be a problem. Also, as laser scanning is not an instantaneous measurement process, methods used to gain access to higher areas must provide a platform stable enough to support the scanning instrument for the duration of the scan. Methods used to achieve elevated coverage must be described in the method statement and outlined in the final survey report. 2.3.8 Targeting Targets located in a defined coordinate system will be used to transform scan data to a common coordinate system: a)Targets should not be positioned, or be so large, that they obscure important details of the subject. b)Targets mounted to the surface of the subject must be fixed in a manner that does not damage the surface. c)A description of the targets to be used must be given in the method statement and the location and naming of the targets is to be clearly given on the site sketches that accompany the final survey report. d)Targets must be captured at 2mm accuracy. 2.3.9 Registration The collected point clouds must be transformed to the single coordinate system. The process of registration can be performed using one of three methods: a)Where registration is done solely via a resection calculation: i.Each scan must contain a minimum of 4 appropriately distributed XYZ control points/targets. ii.The residuals of the registration process and the geometric precision of the estimated parameters should be noted in the survey report. b)Where registration is done using a known station position and orientation: i.The data must include 3 appropriately distributed XYZ control points per scan. ii.The residuals of the registration process and the precisions of the estimated parameters should be noted in the survey report. c)Where registration is performed using surface matching techniques: i.The data must include at least n + 3 appropriately distributed XYZ control points/targets, where n is the number of setups made. The residuals of the registration process and the precisions of the estimated parameters should be noted in the survey report. The geometric accuracy of the fit should be noted in the survey report. A combination of the previous methods may be used to improve the speed and ease of the registration process. 2.3.10 Supporting Imagery Image data to show the location of the scanner and the subject being scanned is required at each setup. This imagery should be of a high resolution and clearly portray the subject in question. Imagery is also required for every scan position to allow fusion of point cloud with imagery without additional registration process. The deliverable should be colored point cloud. 2.4 Delivering Survey Material Certain standard deliverables are required for every survey performed. The following deliverables in digital form are: a)Raw scan and image data b)Scan metadata c)Project metadata d)Control information e)Registration information for all raw scans to the site coordinate system f)Digital images of scanning scenes g)Registered scan data h)Cloud storage services may be accessed through a web service application A hard copy survey report is also required containing: a)Witness/illustrative diagrams outlining the position of scanning stations and control points b)The precision of any parameters derived in the registration process for each scan along with the residuals of the registration c)A summary outlining the completeness of the point cloud and all known data voids d)All site sketches and additional field notes 2.5 Storing & Archiving Point Cloud Data 2.5.1 Data format To assist in the future management of scan data all point cloud data is required to be delivered in Leica Geosystems HDS Cyclone IMP format. 2.5.2 Scan metadata Metadata (information relating to the captured information) is required with all raw scan data and scanning projects. Metadata should be provided in both hardcopy and digital format and must include: a)File name of the raw data b)Date of capture c)Scanning system used (with manufacturers serial number) d)Company name e)Project description f)Survey number (if known) g)Scan number h)Total number of points i)Point density on object (with reference range) j)Weather during scanning k)The file name of an image, located at the point of collection, showing the data collected. The filename should be the same as the filename of the raw data file. 2.5.3 Project Metadata A single project metadata file is required with the project. This must include the following: a)Filename(s) of the raw data used in the registration b)Date of capture c)Scanning system(s) used (with manufacturer's serial number(s)) d)Company name e)Project description f)Survey number (if known) g)Number of individual scans h)Scan numbers of all scans i)Total number of points j)Filename of the control data k)Description of registration method (e.g. All scans registered to local site grid using targeted points) l)An index plan showing the data collected with the individual scan locations shown and named m)Weather during survey n)Any scanner specific information.
