GETTING STARTED WITH QESTLAB
This module covers the process of starting and logging on to QESTLab, and a description of the main screen in QESTLab.
By the end of this module users will be able to start and log on to QESTLab, change their password, have an understanding of the main screen in QESTLab, and use the QESTLab tree to navigate the main areas of QESTLab.
Suggested duration: 15 minutes
Connecting to the Server
The QESTLab application runs on servers in the Coffey Sydney office. You will be provided with a shortcut on your desktop that is used to connect to these machines.
Once you have connected to these machines and logged into Windows you can start the QESTLab.
Logging in to QESTLab
Step 1. To start QESTLab double click the QESTLab Client icon
on the desktop.
Step 2. When QESTLab has loaded the QESTLab log in screen will appear. Enter your QESTLab login name and password provided to you by your QESTLab administrator.
The first-time password that is generated by the system by default is "QEST_password" (minus the quotes). You will be prompted to change this when you access QESTLab for the first time.
Changing your password
The first time you log in to QESTLab change your password to something known only to you.
Step 1. With QESTLab running click the Security menu then select Change Password.
Step 2. In the Old Password field type your current password.
In the New Password field type your new password. Re-enter your new password in the Confirm Password field.
Step 3. Click OK to save your new password.
Logging out
Logout and change user
It is possible to log a different user in to QESTLab without shutting down QESTLab and restarting.
Step 1. With QESTLab running click the Security menu then click Logout.
Step 2. To login another QESTLab user, click the Security menu then click Login.
The new user can then enter their username and password as normal.
NOTE:
1. If you are logged on and the computer that you are running QESTLab on is unattended then there is the possibilty that another person may use the computer to carry out work under your name. When not using QESTLab it is recommended that you either Logout off QESTLab or lock the computer.
2. While you are logged in the Audit Trail keeps a log of every action you make in QESTLab. This is a security feature that enables the tracking of every change made to every field in QESTLab. For this reason you must only work in QESTLab when logged on using your own account.
Close QESTLab
To close QESTLab down on your computer click the File menu then click Exit, or click on the X button in the top right corner of the QESTLab screen
QESTLab operates like Windows Explorer. There is a left hand and a right hand window. Navigation in QESTLab is done using the tree in the left hand window.
The QESTLab tree
Notice the names of the nodes in the tree. Each node allows the user to manage a different area in QESTLab. For example, the Samples node is used to register samples in QESTLab.
The QESTLab tree will look different for users with different levels of permissions in QESTLab. If a user does not have access to a particular area in QESTLab, that node will not be displayed in the tree. For example, if you do not have rights to modify clients in QESTLab you will not see the clients node in the tree. The image below shows all the possible nodes in the QESTLab tree.
Below is a brief description of the different areas in the tree.
| Clients | Users with sufficient rights may add, remove and maintain details for all your customers in this area. |
| Projects | Add, remove and maintain the list of projects your organisation is working on. |
| Work Orders | Work orders are a convenient way to register a group of samples. They are similar to a test request. Select the work orders node to register and search for work orders. |
| Samples | Individual samples are registered and displayed under the samples node. Select the samples node to register or search for samples. |
| Tests/Documents | Select the tests/documents node to search for tests, test reports, or documents other than work orders or samples. Expand this node to see the filters that can be used to search for various documents in QESTLab. |
| Billing | When invoices are raised they are displayed under the billing node. |
| Equipment | Equipment is registered in QESTLab and displayed under the equipment node. Expand the equipment node to see the different types of equipment that can be registered in QESTLab. |
| Lists | QESTLab lists allow you to maintain lists of commonly used items, such as concrete plants, aggregate/soil materials, tester names, and many others. This makes data entry faster and simpler. Lists are displayed and maintained under the lists node. |
| Reports and Charts | This area is used to create and run reports and charts for quality control or other management functions. |
| Specification | Specifications are used to set acceptable limits for test results. They are created and maintained under the specifications node. |
The QESTLab tree can be hidden by clicking on the Show/Hide Tree button 
in the toolbar.
Laboratories
The Lab dropdown box above the tree shows the labs to which you have access.
The global lab
Most users will have access to only one laboratory. In this case you will see this lab plus the (global) lab. The global lab contains data (generally clients, plus other data) that needs to be available to all labs.
Note that if you change the lab selected in the Lab dropdown box the tree will change. If you notice that the tree looks unfamiliar or nodes are missing check that you have your lab selected and not the (global) lab.
Accessing more than one lab
If you have been granted rights to more than one laboratory you will see these labs in the Lab dropdown box. Select a laboratory to restrict the data shown in QESTLab to that lab. (all) will also be shown in the laboratory list. Selecting a lab of (all) simply displays information for all laboratories that the user has access to.
Notice that if all laboratories is chosen, then the tree will group items by laboratory, as shown below for the Lists.
This functionality can be turned off by clicking the Show/hide lab nodes button 
on the toolbar. If this is de-selected then information is not grouped by laboratory.
Filters
Filters are a way of searching for documents in QESTLab, such as samples, test reports, or invoices. Filters are displayed in the left hand window underneath the QESTLab tree. Filters are included with QESTLab and new ones may be created as required by your QESTLab administrator.
Since different filters are used to search for different things, notice that a different filter appears in the filters area depending on which node is selected in the QESTLab tree.

CONCRETE TESTING
Finding work to be done
This module covers the process of finding concrete specimens due for testing.
By the end of this module users will be able to:
- Print a daily worksheet of specimens due for testing on a particular day.
- Use a QESTLab filter to display the electronic worksheet for the day's testing. They will also be able to user a filter to search for specimens using the sample ID or fieldsheet number.
Suggested duration: 15 minutes
Printing a daily worksheet
Follow the steps below to print a daily worksheet for all specimens due for testing on a particular date. Note that the daily worksheet report can be modified by your QESTLab admininstrator, so the name and layout of the report may be slightly different to that presented here.
Step 1. Expand the Reports node in the QESTLab tree. All reports are displayed in this area. Select the daily worksheet report. In the example it is called Concrete Compression Worksheet and found in a group called Concrete Testing. This may be different in your laboratory.
Step 2. The filter is displayed in the QESTLab filter area below the tree. Enter the required test date, or select the date using the calender. Click the Refresh button 
to run the report.
Step 3. The worksheet is displayed in the right hand window. An example is shown below.
Click the Print button 
in the toolbar to print the worksheet.
|
Using the electronic worksheet
QESTLab provides an electronic worksheet for entering test data for all specimens for a particular date, regardless of project. The electronic worksheet may be used to enter data directly into QESTLab during testing or to enter data written on a printed daily worksheet.
Step 1. Expand the Tests/Documents node in the tree and select the filter Concrete Compression Tests. Note that this is not the daily worksheet discussed earlier, which is found under the Reports area in the tree.
Step 2. The Concrete Compression Tests filter is displayed in the data filter area.
Notice that the date defaults to Today. If a different date is required enter the date or use the calendar to select the date. You may also limit the search further by entering a sample ID or a fieldsheet ID. Run the filter by clicking the Refresh button .
Step 3. The specimens are displayed in the tree, grouped by test type. Note that this grouping may be slightly different for your organisation.
Step 4. Click on the test type node in the tree (eg. click on COMP100). The specimens are displayed in the right hand window ready for data entry.
Searching for concrete samples using the sample or fieldsheet ID
You may also want to search for particular concrete samples rather than displaying the electronic worksheet for specimen data entry. To do this follow the steps below:
Step 1. Select the Samples node in the tree.
Step 2. In the filter area, select either Concrete Samples or the Concrete Sample Groups filter.
Step 3. Enter a sample ID, fieldsheet ID or other search criteria and run the filter by clicking the Refresh button . The samples will be displayed in the tree
Search by fieldsheet number
Search by sample ID

Entering raw test data
This module covers the process of entering raw test data for concrete testing. By the end of this section users will be able to:
- Enter concrete test data into QESTLab in order to generate strength and density results.
- Record which technician did the measuring and which technician did the crushing of each specimen.
Suggested duration: 30 minutes
For a full description of each specimen field, see the previous section on The Concrete Specimens. Note that many of the specimen fields have already been entered for the specimens. This was done during sample registration. Enter the test data as follows:
Step 1. Tick the Show Raw Data box 
to display the test data columns in the worksheet.
Step 2. Enter the measurements, weight and load results for each specimen. Press ENTER on your keyboard to move from one cell to the next. There is no need to click in each cell using the mouse.
The strength and density results for each specimen will be calculated and displayed in the grid. If a strength result is less than the F'c the result is highlighed in red.
Step 3. Enter the test time for each specimen. The age in hours will be calculated and automatically populated.
Step 4. By default the failure mode will typically be set to 'N' (Normal). If the failure was not normal then you can use an alternative letter designation as per the 'Failure Mode List'. For example 'S' for Shear, 'A' for Abnormal, etc.
Step 5. Optionally you may select the QESTLab user who measured and crushed the specimen in the Measured By and Crushed By fields.
Test results calculated by QESTLab
When raw test data is entered QESTLab calculates the following results:
- The density and strength result for each specimen.
- Sample average strength/densty - The average strength and density results for specimens of a certain type and age are calculated and stored in the database (eg. the average 28 day strength for COMP100 specimens). This is done for each sample.
- Pair difference - The difference in strength and density results between two specimens of the same type and age is calculated and stored for each sample.
The sample average and pair difference calculations are done for predetermined ages present in a sample. (Typically, 7,28,56 and 90 day). If these differences exceed tolerances (as per AS1379 for Australia) then the results are highlighted in red.
It is important to realise that data entered for specimens on the electronic worksheet is stored with that sample and reported on the concrete test report. The worksheet is simply a convenient way to enter data for multiple samples.

SOILS FIELD TESTING
Finding work to be done
This module covers the process of finding testing work to be done for the typical tests done for soil density testing.
By the end of this module users will be able to:
- Search for a work order using the work order ID or date.
- Search for specific test documents.
Suggested duration: 15 minutes
Overview
Technicians searching for testing work to be done have several options. They can search for:
- Work orders - you can search for all work orders for a particular project, date range or other criteria. You can also use the work order ID to bring up a particular work order. Test data may then be entered for all the samples in this work order.
- Specific Tests - instead of searching for each work order, you can search for all instances of a particular test, such as all incomplete moisture contents, that are waiting to be done. This will display all these tests, regardless of which job they belong to.
The method for searching is optional and may vary between laboratories.
Searching for work orders
To search for work orders for a particular job, or using the work order ID, follow the steps below:
Step 1. Click on the Work Orders node in the tree.
Step 2. If you have access to more than one laboratory then ensure the correct laboratory is selected in the lab node above the QESTLab tree.
Step 3. The default filter is displayed in the filter area. You can use this filter or select another one from the list.
Enter as many criteria as required. For example you may just enter the client and project, work order ID, or date range. You have to enter information in at least one field.
To search by project:
- To select a client or project click the
button and select the item(s) from the list. - If a date field exists, then a date can be selected from the calendar by clicking on the button.
To search by work order ID simply enter the ID in the work order ID field.
Step 4. To run the filter click the Refresh button 
. The work orders returned by the filter are displayed in the tree under the Work Orders node. Results are grouped by project. Expand the project to see the work orders.
Entering final test data
When final moisture content data is available this should be entered as follows.
Entering final moisture content values
Expand the Moisture Content section of the work order screen and enter the final moisture content data.
Updating compaction data
Hilf
To update your hilf data with the final moisture content data, simply click on the Hilf Ratio worksheet in the tree. It is updated automatically.
Dry Density
To update maximum dry density data with the final moisture content data, follow the steps below.
Step 1. Click on the MDD node in the tree.
Step 2. Enter the final moisture content data on the MDD worksheet.
Step 3. On each of the other samples, click on the Relative Compaction node in the tree and import the MDD sample by clicking the Import button as shown.
Remember the 'Mass of wet soild, rock, container' field must have a non-zero entry to calculate final results.
|
Searching for test documents
QESTLab comes with several useful filters that allow you to search for all instances of specific test documents (eg. Moisture Content documents). These filters are found under the Tests/Documents node in the tree.
Useful filters here include:
- Moisture completion - returns incomplete moisture tests.
- Hilf density tests - returns incomplete hilf density tests.
- Maximum dry density tests - returns incomplete MDD tests.
Note that these filters will run immediately they are clicked and do not required any search criteria. Other filters require you to enter specific search criteria. If you do need to enter search criteria remember that Complete = 0 will find all incomplete tests.
More filters are available in the normal filter area underneath the tree.

Entering raw test data
This module covers the process of entering test data for the typical tests done in soil field testing.
By the end of this module users will be able to enter test data:
- Directly into the work order screen for simpler tests.
- On a electronic worksheet for more complex tests, such as the maximum dry density.
Entering data on the work order screen
As mentioned above, test data for some tests can be entered on the work order screen. For example, field density and moisure content test data, which doesn't required complex calculations may be entered on the work order screen. The advantage of entering data on the work order screen is that data can be entered for all samples on the one screen.
Entering data on the electronic worksheet
Other tests such as the maximum dry density have more complex calculations. Therefore data needs to be entered on the electronic worksheet provided for this test. The maximum dry density worksheet is described below.
|
The maximum dry density electronic worksheet
The maximum dry density electronic worksheet is shown below.
Entering maximum dry density results
Step 1. The Details tab is displayed. Enter the required details.
Step 2. Select the Equipment tab. Select a mould. The Mould Type and Volume fields are populated with the values for this mould. Enter the mould mass.
Step 3. Select the other equipment used for the test.
Step 4. Enter the number of specimens in the Specimens box and hit ENTER. A column is added for each specimen. The Mass of Mould is populated with the value entered in the equipment area.
Enter the remaining data for each specimen. The results are shown in the Results section.
Step 5. Select the Chart tab to see the MDD chart.

OTHER AGGREGATE/SOIL AND ASPHALT TESTING
Finding work to be done
QESTLab caters for a large number of aggregate/soil tests. Each has its own custom electronic worksheet for the entry of test data. This module covers two methods for finding work to be done:
- Finding a sample and all tests for that sample.
- Finding a particular test for all samples that require that test.
By the end of this module users will be able to find samples or particular test documents, using a variety of search criteria.
Suggested time: 15 minutes
Overview
When a technician wants to find testing work that needs to be completed they have a number of options. They can search for all samples for a particular job, all samples tested over a particular period, and a number of other search criteria. If they know the sample number they can just bring up that sample.
Alternately, technicians can search for all instances of a particular test that need to be done. For example they can find all CBR tests that are currently incomplete, regardless of which job they come from.
Searching for samples
To search for samples follow the steps below:
Step 1. Click on the Samples node in the tree.
Step 2. If you have access to more than one laboratory then ensure the correct laboratory is selected in the lab node above the QESTLab tree.
Step 3. The default filter is displayed in the filter area. You can use this filter or select another one from the list.
Enter as many search criteria as required. You have to type information in at least one field but you do not have to enter all criteria. For example you may just enter the sample ID, or just the date range.
Note:
- Some fields have lists associated with them (In this case Client ID, Project ID and Date Between). Click the button to display the list items.
- If a date field exists, then a date can be selected from the calendar by clicking on the button.
Step 4. To run the filter click the Refresh button . The results of the filter are displayed in the tree under the Samples node.
Note that for this filter the samples are grouped together under the project. Expand the project to see the samples. Then expand the sample to see the test documents. Incomplete tests are shown in bold. In the example above all the tests are incomplete.
Step 5. To enter test data, select the test document for the test you are interested in. The test document for this test will be displayed in the right hand window ready for data input.
|
Searching for test documents
Remember the Tests/docs area in the QESTLab tree, that had filters that allowed you to search for particular soils tests that needed doing. Well, similarly there are filters that can be used to find grading tests, CBRs, Atterbergs and the like, that need doing. Remember that these filters are added by your QESTLab administrator. If the filter you need isnt there your system administrator may be able to add it for you.
To use one of these filters to search for specific tests follow the steps below.
Step 1. Click on the Tests/Documents node in the tree. The more common filters, which come as standard with QESTLab, are listed in the tree.
Other filters, added by your system administrator, are found in the filter area.
Step 2. Select the filter for the test you want. In the example the filter Grading tests is used. It searches for all grading tests.
Step 3. Enter required search criteria in the filter area. To search for:
- Only incomplete tests - use the last search criteria called Complete. Enter the value 0 for FALSE, or 1 for TRUE. For example to display all incomplete grading tests use the search criteria Complete = 0 and leave everything else blank.
- Sample ID - enter the work order or sample ID.
- Other criteria - enter other criteria as required.
To run the filter click the Refresh button .
Step 4. Seach results are grouped by project. Expand the project to see the test documents.
Step 5. Click on the test document in the tree to display the test document in the right hand window ready for data entry. Note that each different test document is specialised for the entry of specific results.

Entering raw test data
This module covers the process of entering test data into an electronic worksheet.
By the end of this module users should be be able to:
- Enter test data into an electronic worksheet such as the particle size distribution worksheet.
- Record, on the worksheet, which tester performed the test.
Suggested time: 30 minutes
QESTLab electronic worksheets
QESTLab provides a custom electronic worksheet for each test method. Data is entered into the worksheet during testing, and QESTLab calculates the test results according to the relevant standard.
The tests to be conducted on a sample are displayed in the tree under the sample. To display the worksheet for a particular test click on that test in the tree.
- In the Equipment area, select the equipment used for this test.
- In the Details area enter the test data.
- The results will be calculated and displayed in the grey result fields.
Some worksheets such as the PSD worksheet contain more complex calculations.
The PSD worksheet is described in detail below.
The particle size distribution document
QESTLab catered for different test methods for performing a particle size distribution. This functionality is provided from a single code base with a dynamic user interface that changes depending on the test methods requirements.
This document covers all the possible functionality. The features mentioned will not be available to all test methods.
Options
The options displays up to 4 drop down boxes that effect the raw data that can be entered and how the calculations are performed.
| Drop Down Combo | Values | Function |
| Percentages | Passing (Total) | The final calculated values will be percentages passing the sieves. |
| Retained (Individual) | The final calculated values will be percentage retained on the individual sieve. | |
| Weights | Individual | Weights entered are for the individual sieve. The balance is cleared between each sieve weighed. |
| Cumulative | Weights entered are cumulative and include the current and all previously weighed sieves. | |
| Washing | None | The sample is not washed over a fine sieve. |
| Total | The entire sample has been washed over a fine sieve (usually 75um / No. 200) | |
| Split | The split sample has been washed over a fine sieve (usually 75um / No. 200) | |
| Drying | Total | The entire sample has been dried. |
| After Split | The sample down to the split was not dried. The sub sample resulting from splitting was dried. |
Equipment
Select the equipment used in performing the test. This includes the Balance, Sieve Set, Sieve Shaker and equipment used for drying the sample.
In the case of a sample that has been split select a second set of equipment that was used on the sub sample. If a sieve set is selected that has its diameter specified in the equipment schedule then the overload mass for this sieve will be displayed in the data entry grid.
Chart
The chart shows the sieve analysis represented on a semi-logarithmic chart. Also shown are specification limits which will be highlighted in red if the test results do not conform. This chart is updated in real time.
Raw data and results
Enter the raw data (masses). Final test results are calcuated and displayed. The columns in this grid are always the same, they are:
| Sieve Size | The sieve size that is being tested. |
| Cumulative/Non Cumulative Mass | Either the mass retained on the sieve, or the cumulative mass from the current and all previous sieves. |
| Max Mass | The maximum mass allowed on this sieve before it is overloaded. |
| % Pass (Total) / % Retained | The calculated result. |
| Limits | The specification limit for the sieve. |
The rows in the grid vary depending on the options set and the sieves selected in the specification limit.
How is? / How do I?
How is the Total Dry Mass determined?
The figure for the total dry mass can be reached several different ways depending on the test method.
The entire sample could be dry / have been dried before commencing the test and the dry sample weighed. In this case the user can directly enter the Total Dry Mass.
The entire sample could be dried as part of the test procedure. In this case the user could still enter the Total Dry Mass or they may choose to, also enter the Wet Mass and possibly the Tare Mass (weight of the tray) and Tare Mass + Wet Sample.
The moisture content of the test could have been determined in a separate test on a sub sample. In this case register the moisture content as a test on the same sample (a sibling test to the PSD) and enter the details. By default this moisture content will then be used to determine the Total Dry Mass when you enter the Wet Mass on the PSD screen. This behaviour can be disabled via the document option ‘Do Not Use Sibling Moisture’. See the document IQ0018 QESTLab System and Document Options.htm for more details.
For some test methods the ‘Total Dry Mass’ is calculated based on the moisture content of the sample after the first split. In this case the option ‘Drying After Split’ is selected. The wet mass of the material passing the split sieve is recorded, as is the ‘Split Wet Mass’ and ‘Split Mass’. The moisture content is determined from the ‘Split Wet Mass’ and ‘Split Mass’. The dry mass of the material passing the split sieve is then calculated and added to the material retained on sieves prior to splitting. This value is the ‘Total Dry Mass’. This assumes that the material already retained are large particles that do not retain any moisture.
How do I split a sample?
When you are required to split a sample and use a smaller portion for the remainder of the test you double click in the cell that contains the last sieve tested before splitting. The system will prompt asking if you want to split after this sieve. You can split a grading twice in this way, to allow for a coarse, intermediate and fine fraction. Double clicking on an existing split will give you the option of removing it. The calculation of percentages passing for the split material will be automatically determined taking into consideration what portion of the entire sample is represented by the material.
Where do I enter details about washing the sample and the Finer 75um (No. 200)?
When washing material over a fine sieve (75um) you need to record the mass retained after washing and drying. This figure is entered in different places on the grid depending on when the washing is performed. If the washing took place for the entire sample then an ‘After Wash’ row appears below the ‘Total Dry Mass’. If washing after a split the ‘After Wash’ appears below the ‘Split Mass’. Remember the value entered is for the dry mass after washing. If you weigh this material in the tray (and have provided the weight of the tray in the first row of the grid) then you will need to set the document option to ensure the mass of the tray is removed from the figure entered before the Finer 75um figure is calculated. See the document IQ0018 QESTLab System and Document Options.htm for more details.
This figure will in turn be used to calculate the Finer 75 um (No. 200) which appears at the bottom of the grid. Some test methods allow for the determination of the Finer 13.5um sieve. This functionality is activated via a document option. See the document IQ0018 QESTLab System and Document Options.htm for more details.
Does the electronic worksheet check for material loss?
For most test methods the electronic worksheet will check to see if material loss has exceed 1%, or a figure provided by the method. This is displayed in red along side the ‘Total Dry Mass’ and the ‘Split Mass’. If after splitting you weigh the material in the pan and it includes all the split material then you will need to set a document option so the material loss check takes this into consideration. See the document IQ0018 QESTLab System and Document Options.htm for more details.
I separated the sample and sieve in two or more lots to avoid overloading sieves, can this be recorded?
Sieves have a maximum acceptable amount of material that can be tested in a single operation. Where the sieve diameter has been entered in the equipment schedule, this maximum mass is displayed in the data entry grid. When a tested mass is entered that exceeds this value the user is warned about the overloading of the sieve and the problem is highlighted. If the sample was tested in two or more lost then enter the mass retained on the sieve as the individual values separated with commas. When you move of the cell the combined mass will be displayed. When moving back on the cell the original breakdown as entered will be shown.
