Project
Cloud-Based Time and Attendance System for Construction Sites and Head Office
RAMS PDKS is a fully cloud-based time and attendance and human resources platform that centrally manages the entries and exits of permanent and subcontractor staff working at RAMS Türkiye's head office, sales offices and construction sites.
RAMS PDKS is a fully cloud-based time and attendance and human resources platform that centrally manages the entries and exits of permanent and subcontractor staff working at RAMS Türkiye's head office, sales offices and construction sites.
On construction sites, staff clock in and out by passing through full-height turnstiles or tripod turnstiles with card access; card reader panels are used at office and door access points, and field and office staff use a mobile app with location and QR verification. All card access devices on site connect to the cloud through an IoT gateway that Karatsoft developed for this purpose. Thanks to the gateway, every device is managed in real time without the need for a static IP, NAT rules, firewall settings or port forwarding on the modem.
A new employee's card details are transferred to the access devices within seconds; when an employee leaves, their card is removed from the devices just as quickly. The platform consists of a web management panel, an iOS/Android mobile app, an IoT connectivity layer and an integration API that provides two-way data exchange with enterprise systems. The employee list, card and device management, person groups, shifts, leave, subcontractor tracking, daily and monthly reports and automated report emails are all brought together in a single panel.
RAMS Türkiye is a real estate development and construction company that runs several large-scale construction sites at the same time. At each site, hundreds of workers from dozens of subcontractors work alongside the permanent team; knowing who enters and leaves the site, and when, is critical both for occupational safety and for subcontractor progress payments.
In the previous setup, site entrances were controlled with turnstiles, but the devices at each site worked in isolation, cards were defined locally and data was collected at the end of each period. Activating the card of a newly arrived subcontractor worker could take hours, and cancelling the card of someone who had left could sometimes take days. The head office had no real-time view of the sites; reports on late arrivals, absences and undertime were prepared by hand.
Karatsoft's time and attendance infrastructure was adapted specifically for RAMS Türkiye to meet this need. Screens suited to the realities of construction sites, subcontractor-based lists and reports, card and device management, person groups and automated report distribution were added. At the heart of the project sits the IoT gateway, which connects the turnstiles and card reader panels on site to the cloud without any network configuration. As a result, every new construction site can be managed centrally as soon as the devices are installed and the gateway is plugged in.
Tell us what you need; we'll set out the scope, integrations and roadmap in writing in the first meetings. Built around the way you work, without touching your ERP, accounting or banking systems.
The main screens and their highlights: on every image we magnify the area that matters most. Tap an image for details.
The number of people currently inside, daily entries, late arrivals and connected device status across all sites on a single screen. Passes from turnstiles and panels appear in a live feed, monitored alongside site occupancy and the health of the IoT gateways.
Permanent and subcontractor staff are listed with their department, company, position, site and card number. Selected people can be activated or deactivated, updated or assigned cards in bulk.
Personal details, profile photo, card and access permissions, recent passes and personnel documents on a single page. Shift, entry and exit, leave and mobile preferences are managed in tabs.
Branch, department, position and person records are imported from a single file using a field-mapping wizard. Rows with the subcontractor column filled in are automatically created under the relevant company.
As soon as a card is enrolled for a person and their authorized access points, it is sent to the turnstiles and panels. Each card's status on the devices and its last sync time are visible; the card of a departing employee is removed within seconds.
Full-height turnstiles, tripod turnstiles, card reader panels and IoT gateways are listed by site. Online status, today's pass count, number of registered cards and last sync are monitored; cards can be resent and turnstiles opened remotely.
On-site devices connect to the cloud through the IoT gateway over a single encrypted outbound channel. No static IP, NAT rule, port forwarding or firewall configuration is required; if the connection drops, passes are stored on the device.
Access permissions, time restrictions, shifts and reporting are managed through person groups. A person added to a group automatically receives the group's permissions, and their card is sent to the relevant devices instantly.
Construction site, office and security shifts are defined day by day, and night shifts that run into the next day are supported. Tolerance and break definitions, flexible shifts and person/group assignments are all in one place.
Delays relative to shift start, net of tolerance, are shown in a matrix by person and day. The report can be narrowed with site, person type, subcontractor and threshold filters, and is emailed to managers.
Each cell shows the entry and exit time together with the point where the pass was made. Regular hours, overtime, undertime, absences, leave and holidays are color-coded; overtime/undertime totals appear at the end of each row, and the report goes to Excel in one click.
Which reports go to which manager, on which day and at what time, is defined per person. A subcontractor breakdown is added as a separate table; the monthly progress payment report reaches accounting at the start of each month.
Subcontractors are listed with their registered staff, the people currently on site and their monthly late arrival counts. One click takes you to each company's person list, timesheet and man-day (progress payment) report.
Page permissions are restricted by position, and data scope by site and company. Construction site management sees its own site, the subcontractor supervisor sees their own company, and HR sees the entire organization.
Sites, departments, positions and subcontractors in a single hierarchy. Each site's number of people and devices, as well as its mobile verification method, are shown on the list.
A site's access points and devices, QR codes (standard and dynamic), mobile access policy, location radius and subcontractor time restriction are managed on a single page.
Targeted announcements to a site, department, company or person group, delivered by mobile push notification and email. Read rates are tracked per announcement, and files can be attached.
Pending requests, the hierarchical approval flow and the leave entitlement table in one place. For leave that requires a document, the medical certificate or written request the employee uploads from the mobile app appears on the approval screen and is stored in their personnel file.
From a single app, staff clock in and out with QR and location verification, view their movement history including turnstile passes, and submit leave, salary advance and expense requests. iOS and Android.
Instant notifications and alerts, quick actions and live data: users and field teams get their work done from their phones, without waiting.
On construction sites, permanent and subcontractor staff clock in and out by passing through a full-height or tripod turnstile with their card; card reader panels are used at office doors.
The IoT gateway developed by Karatsoft connects all readers on site to the cloud without requiring a static IP, NAT rules, port forwarding or firewall configuration.
A new employee's card is transferred to the access devices as soon as it is enrolled; a departing employee's card is removed from the devices just as quickly.
No servers, licenses or on-premises installation; time and attendance devices integrate seamlessly with the cloud system through the IoT layer. Adding a new site requires no infrastructure changes.
When the connection drops, passes are stored on the device and transferred in full once the connection is restored.
Subcontractor staff are created under their company; lists, reports and the man-day progress payment report are broken down by company.
Access permissions, time restrictions and shifts are granted through groups; a person added to a group automatically receives all of its permissions.
Employees can be activated or deactivated, updated or assigned cards in bulk.
Branch, department, position and person records are imported from a single file using a field-mapping wizard.
People currently inside, daily entries, late arrivals and device health on a single screen, with passes flowing in live.
The online status, registered card count and last sync of turnstiles and panels are monitored; cards can be resent and turnstiles opened remotely.
Each cell shows the entry and exit time together with the point where the pass was made; overtime/undertime totals and Excel export are ready.
Delays net of tolerance, by person and day, with subcontractor and threshold filters.
Late arrivals, early leavers, absence, overtime, undertime, excess breaks, passes at a different branch and people currently inside.
Each manager receives their own site's reports by email on the set day and time, with a subcontractor breakdown.
Night shifts, flexible shifts, break and tolerance definitions; assignment to individuals and groups.
Hierarchical, single-approver or custom approval flow; documents such as medical certificates and written requests are uploaded from the mobile app and stored in the personnel file.
The person's profile stores their photo, contract, certificates and other personnel documents.
Page permissions are restricted by position, and data scope by site and company; all manual interventions are logged.
Clock-in and clock-out with QR and location verification, movement history, leave, salary advance and expense requests, announcements; iOS and Android.
Announcements for a specific site, company or group, with push notifications, email and read tracking.
Two-way sync with enterprise HR and ERP systems through person, branch, QR code and entry/exit services.

How we work
This project was run on the same four principles; yours will be too.
Scope, integrations and roadmap are written down and agreed in the first weeks; no surprises along the way.
ERP, accounting, banking, e-invoicing: whatever you run, we integrate on top of it and your data stays where it is.
Role-based access, two-factor authentication, data-protection compliance and a log of every action are built into the foundation, not bolted on later.
Maintenance, monitoring and new releases come from the team that built the project; someone who knows your system is always a call away.
RAMS PDKS
The management console is the first screen a manager sees on opening the panel: at a glance, it summarizes who is inside right now at the construction sites and head office, the day's entries, late arrivals and the connection status of the devices on site.
The indicators in the top row show the number of people currently inside, today's entries split between permanent and subcontractor staff, late arrivals and online devices. Below them, the live pass feed lists every event with its time, person, site, device and direction; full-height turnstile, tripod turnstile, card reader panel and mobile QR passes all land in the same list. The right-hand column tracks site occupancy and the status of each IoT gateway.
Previously, the head office could not see the real-time status of the sites, and late arrival lists were compiled by hand every morning. The console puts this information in front of managers the moment it happens. HR starts the day knowing how many people are inside at each site; construction site management follows the feed for its own site. A gateway or device whose connection is weakening shows up on the console before a gap in the timesheet is noticed, and is dealt with the same day.
The employee list brings all permanent and subcontractor staff together in a single table; it can be filtered by site, department, company, status and person group, and bulk actions on the selected people are completed in a single step.
Each row shows the full name, permanent or subcontractor status, department or company, position, site, card number, status and access type; the department column was added to the list for RAMS Türkiye. When rows are selected, buttons for bulk activation, deactivation, update and card assignment appear at the top. In a bulk update, only the fields with a value entered are changed. Double-clicking a row opens the person's profile.
On construction sites with high subcontractor turnover, dozens of cards are enrolled and dozens are cancelled every week. The relevant company is filtered in the list, its people are selected and deactivated in a single action, and the cards of deactivated staff are removed from the access devices just as quickly. Cards for a newly arrived team are assigned from the same screen. This ends the work of opening records one by one and closes the risk of a departed employee's card staying active on site.
The person profile answers the key questions about an employee on a single page: which card they carry, which points they can pass through, when they last passed, which documents are in their file and which shift they work.
The profile opens when a person is double-clicked in the employee list. On the left are the profile photo, status and the card box: card number, card status, authorized access points, mobile access method and last pass. The tabs on the right cover personal details, shift, entries and exits, leave, documents and mobile preferences. Entries and exits can be filtered by day, month and year; the leave tab shows earned, used and remaining leave.
When an incident occurs on site or a subcontractor worker's timesheet is questioned, the profile shows which point the person entered and exited through that day. Contracts, certificates and other personnel documents are kept in the personnel file; medical certificates and written requests the employee uploads from the mobile app go into the same file. The profile photo identifies the person at first glance in both the list and the profile. There is no need to keep separate folders to find documents.
Bulk import from Excel moves the organization's existing personnel and organizational spreadsheets into the system in one go; columns are mapped in a wizard, subcontractor workers are created under their companies, and the system starts fully populated from day one.
The user downloads and fills in the Excel template or uploads their existing file directly; if the file has more than one sheet, the sheet to import is selected. Then, for each system field, the matching column in the file is chosen: full name, Turkish national ID number, site, department, position, subcontractor, card number, hire date and phone. Required fields are marked. Once mapping is complete, people are imported with a single button; rows with the subcontractor column filled in are created under the relevant company.
RAMS Türkiye's hundreds of person, branch, department and position records were held in spreadsheets of different formats, and the system had to start fully populated on day one. The files sent by the organization were imported with the wizard, and the organizational structure and personnel list were set up without entering records one by one. The same screen is still useful today: when a new construction site opens or a subcontractor brings in a whole team, the list enters the system in one go and is ready for card enrollment.
The card enrollment screen manages the entire lifecycle of card access credentials: a card is linked to a person and to access points and reaches the devices the moment it is saved; a departing employee's card is withdrawn from the site just as quickly.
In the card enrollment window, the person is selected, the card number and card technology are entered, the validity period is set and the access points the card will open are ticked. The Save and send to devices button delivers the card via the IoT gateway to the selected turnstiles and panels. The card list shows each card's status on the devices and its last sync time; the indicators at the top count enrolled cards, cards added today, cards removed today and cards awaiting sync.
Previously, activating a new subcontractor worker's card took hours and cancelling a departing employee's card sometimes took days, because cards were loaded onto each device one by one. Now a card goes to all relevant devices the moment it is enrolled, and a termination or deactivation removes it within seconds. Only authorized people get onto the site, and this is enforced at the gate. Because sync status is visible on screen, no one has to ask the site whether a card has reached the device.
Device management brings all the access hardware at the construction sites and offices together in a single list; which turnstile is online, how many cards it holds and when it was last synchronized are monitored centrally, and remote intervention is possible when needed.
The list shows full-height turnstiles, tripod turnstiles, card reader panels and IoT gateways with their site, type, today's pass count and status. When a device is selected, the panel on the right shows the gateway it is connected to, the number of registered cards, the last sync, the reading direction and the software version. From the same panel, cards can be resent to the device, the turnstile can be opened remotely and the device's pass log can be viewed. The indicators at the top summarize the total number of devices, online devices and gateways.
In the old setup, the devices at each site worked in isolation, cards were defined locally and data was collected at the end of each period. In RAMS PDKS, every device is connected to the cloud through the gateway, so its status is visible centrally. Cards can be resent to a turnstile that is missing some, and a stuck passage can be opened remotely. At a new construction site, the devices are managed centrally as soon as they are installed and the gateway is plugged in; no network configuration or local installation is needed.
The IoT connectivity architecture is the heart of the project: the gateway Karatsoft developed for this purpose collects the turnstiles and card reader panels on the construction site over the local network and connects them to the cloud, with no static IP, port opening or firewall configuration required.
An IoT gateway is installed at each construction site. It communicates with the full-height turnstiles, tripod turnstiles and card reader panels on site over the local network, and connects to the cloud through a single encrypted channel that it opens outbound. Because the connection is established from the inside out, no NAT rule, port forwarding or static IP is needed on the modem. If the internet goes down, passes are stored on the device and transferred in full once the connection is restored.
Internet access on construction sites usually comes from an LTE modem; there is no static IP, and modems and carriers change frequently. The network settings required by conventional time and attendance devices had to be redone at every site, and often could not be done at all. With the gateway, a new construction site is managed centrally as soon as the devices are installed and the gateway is plugged in. No servers, licenses or local installation are required, and the IT team does not have to plan separate network work for each site.
Person groups make it possible to manage access permissions team by team instead of person by person: authorized sites, time restrictions, shifts and reports are defined on the group, and every person added to the group receives them automatically.
The group list shows each group's number of people, the sites it is authorized for, its time window and its status. When a group is opened, its access permissions, time restriction, shift and the reports it is included in appear in a single panel; below, members are listed with their company and card number. A person added with Add member automatically receives the group's permissions and shift, and their card is instantly sent to the relevant turnstiles and panels.
On a construction site, teams come and go by company and trade. When a subcontractor's team is gathered into a single group, adding a new worker to the group is enough to load their card onto the right gates and assign their shift. The time restriction applied to subcontractors comes from the group, while the permanent team works under its own rules. Because person groups can also be changed in a bulk update, permissions are renewed in a single action when a team moves to another construction site.
Shift management defines the different working patterns of construction sites, offices and security in one place; late arrival, early departure, overtime and undertime are calculated automatically from these definitions and the tolerance and break rules.
When a new shift is added, entry, exit and break times are entered separately for each day; one day's settings can be copied to the other days, and extra breaks can be added if needed. For night shifts, the End on next day option is ticked, so a shift that starts in the evening closes correctly the next morning. In the tolerance definitions, early and late entry allowances, early and late exit allowances and the minimum overtime duration are entered in hours and minutes. A shift can be set as the default.
On a construction site, day crews, night workers and security shifts run at the same time, while offices can use flexible shifts. Because all of them are defined in the same system, every turnstile pass is evaluated against the person's own shift. Shifts are assigned to individuals or person groups, and the weekly day off is defined in the same place. The late arrival, early leaver, undertime and excess break reports draw on these rules, leaving no manual calculations for HR.
The monthly late arrivals report shows in a single table who was late, on which day and by how much over a month; delays are calculated from shift start net of tolerance, and the report can be filtered and emailed to managers.
People are listed in the rows and the days of the month in the columns; each cell shows that day's delay in minutes, and the number of late days and the total delay are summed at the end of each row. Delays are calculated against the person's shift start, net of the defined tolerance. The report can be narrowed with site, month, person type, subcontractor and threshold filters. The indicators at the top summarize the month, and the report can be printed or exported to Excel.
Site managers and HR used to compile late arrival lists themselves every morning. Now the month's table is ready, and recurring delays are visible at a glance. The subcontractor filter shows which company the delays are concentrated in, providing concrete data for a conversation with the company supervisor. The Send to managers button forwards the report to the relevant people; with an automated email setting, the same report arrives on its own on the set day and time.
The Detailed Monthly Report brings together, in a single table, each permanent and subcontractor employee's day-by-day entry and exit times for the month, the gate they used and their working-hours status; timesheet, overtime and absence checks are done here.
The report is opened by selecting the site, month, year and person type, and can be narrowed to a single company's staff with the subcontractor filter. The calculation is based either on the first entry and last exit of the day or on all entries and exits. Cells are color-coded by status: no shift defined, regular hours, overtime, undertime, unpaid leave, absent, weekly day off, public holiday, paid leave and not working. Hovering over a cell shows the shortfall or surplus in working time.
On a construction site, an employee may pass through the full-height turnstile at the main entrance, the service gate or via mobile QR during the day; because the access point sits in the same cell as the time, the question of which gate they entered through is answered without looking for a separate record. At the head office, HR and accounting carry the totals at the end of each row (days worked, days absent, leave days, overtime and undertime) straight into timesheet and progress payment preparation; the report downloads to Excel in one click.
Automated Report Emails defines which reports each manager receives, with what scope, how often and at what time; the reports land in the relevant manager's inbox at the set time, without anyone having to open the panel.
The recipient list shows each manager's position, sending time, frequency, number of selected reports and the number of people in scope. When a recipient is opened, the frequency is set to daily, weekly or monthly, and the day, hour and minute are chosen. Report types include the daily report, late arrivals, early leavers, absence, overtime, people currently inside, the detailed monthly report and the timesheet. The scope is set by site and person type, and the subcontractor breakdown is added by company as a separate table.
Without opening the panel, the site manager starts the day with the late arrival and absence list for their own site; because subcontractors appear in separate tables, an understaffed crew is spotted immediately. At the head office, HR regularly receives the summary for all sites, and accounting receives the subcontractor man-day report at the start of each month. Compiling lists by hand every morning is a thing of the past; which report goes to whom and when, along with the last sending time, is tracked in a single list.
Subcontractors tracks every subcontractor working on site together with its staff, its real-time headcount on site and its delays; the man-day report for company-level timesheets and progress payments is generated here.
Each subcontractor is defined once by name; its employees are linked to it when their person record is created, or from rows with the subcontractor column filled in during Excel import. The list shows, side by side, the sites where the company works, its registered staff, the people currently inside based on turnstile passes and this month's late arrival count. From a company's row you can go to its person list or timesheet; the side panel compares monthly man-days by company.
Subcontractor progress payments are based on the monthly man-day figure calculated from turnstile passes; the report is exported to Excel with a company breakdown and forwarded to accounting, so there is no need to total timesheets by hand company by company. Construction site management sees in real time how many people each company has on site, and for occupational safety it is always known who is inside. The subcontractor supervisor sees only their own company's staff, while the head office compares all companies in a single table.
Role Management determines who can open which page in the panel and which sites' and companies' data they can see; permissions are granted not to individuals one by one but through roles linked to positions, and are managed from a single place.
A role is first created with a name and description, and positions are then linked to it; several field positions, such as site manager, can share the same role. The authorization screen contains a tree at menu, section and page level; you can search within the tree, expand branches, select all or clear the selection. Saved page permissions apply to everyone in that position. Beyond page access, the critical actions that can be performed on a page are also restricted separately through position permissions.
Construction site management sees only the people and reports of its own site; the subcontractor supervisor cannot go beyond their own company, while HR manages the entire organization. When a new site manager starts, assigning them to the position is enough; page permissions and data scope come automatically from the role. In a multi-site, subcontractor-heavy organization, this separation ensures that personal and personnel file information is visible only to the relevant manager, and every manual entry/exit intervention is logged along with who made it.
Organizational Structure holds RAMS Türkiye's head office, sales offices and construction sites, together with their departments, positions and subcontractors, in a single hierarchy. Reports, permissions and approval flows are built on this structure.
Each site is created with its type, name, phone, email and description, and its location is marked on a map. Departments are kept in a separate list, while positions are defined with the department they belong to and their parent position, so who reports to whom is recorded in the system. The site list shows each site's location, number of people and devices, mobile verification method and connection status; in the side panel, departments, position counts and subcontractors sit in the same tree.
The position hierarchy determines which manager leave requests go to, and the site and company breakdown sets the boundaries of reports and role scopes. When a new construction site opens, the site is defined, devices are connected and staff are assigned; no additional installation is needed on the infrastructure side. The head office compares the people, devices and connection status of all sites on a single screen; RAMS Türkiye's existing branch, department and position records were also imported into this structure from Excel.
Site Details brings together, on one page, the access points, devices, QR codes and mobile access rules of a single construction site or office; how people enter and leave the site is defined and monitored here.
At the top of the page are the number of registered people, the people currently inside based on turnstile counts and the number of access points. The access points table shows the full-height turnstile, tripod turnstile, card reader panel and IoT gateway with their status. QR codes are added with a location title, type and status; for dynamic QR codes, a PIN and expiry date are defined. The access policy sets the mobile method, location radius, passes at a different site and the subcontractor time restriction.
At a site where GPS and QR are selected together, staff can clock in from the mobile app only when they are within the defined radius and scan the site's QR code; clocking in remotely is not possible. Because the time window for subcontractor teams is kept per site, each construction site applies its own working pattern. The site manager sees the device and connection status of their site at a glance, while the head office reviews each site's rules in the same page layout and changes them centrally when needed.
The Announcements screen gets information intended for construction sites and the head office to the right people; announcements reach the target audience by mobile push notification and email, and who has read them is tracked per announcement from the panel.
An announcement is prepared with a title, content and attachments. The target audience is selected as a site, department, subcontractor or person group; with person type, you can target permanent staff only, subcontractor staff only or both. If needed, individuals can also be ticked one by one from the list. The announcement is published immediately or saved as a draft. The list shows each announcement's read rate and status, and its details show, person by person, who it was delivered to and whether they have read it.
Announcements such as a change in working hours, a call for occupational safety training or card distribution information land on employees' phones without waiting to be pinned to a notice board. Subcontractor staff are informed through the same channel, so the company supervisor does not need to notify their team one by one. Thanks to read tracking, construction site management can identify those who have not seen a critical announcement and remind them separately on site, while the head office delivers the same message to all sites in one go.
Leave Management brings together on one screen the leave requests coming from the mobile app, the approval flow and each employee's entitlement status; approved leave is processed directly into the timesheet, and any supporting document stays in the personnel file.
The employee opens a request by selecting the leave type, the start and end dates, a half day if needed, and the person who will cover for them; the system calculates the return-to-work date and the total number of leave days. The request is listed on the manager's screen with the leave type, dates, number of days and attached document, and is approved or rejected with one click. The approval flow can be set up as hierarchical, selected positions, custom or shortened hierarchical; for subcontractor staff, the company supervisor becomes an intermediate step.
For leave that requires a medical certificate or written request, documents do not circulate on paper: the employee uploads them by phone from the site, the manager sees them on the approval screen and the document is stored in the personnel file. Because the leave and entitlements table shows the hire date, length of service, entitlement, and days used and remaining, HR does not calculate leave balances by hand. Since approved leave is processed into the timesheet, leave days appear in a separate color in the detailed monthly report and are not confused with absences.
The RAMS PDKS mobile app is the iOS and Android app in which field and office staff clock in and out with QR and location verification, see all their passes and submit leave, salary advance and expense requests.
Employees sign in with their email and password; the home screen shows their name, title and unit, along with the day's entry status. To clock in or out, depending on the site's rule, they scan a QR code with the camera, have their location verified, or both. The Movements screen lists all turnstile, card reader panel and mobile passes with date and time, and the monthly list shows each day's entry and exit times. Leave, advance and expense requests are tracked along with their approval status.
At office locations without a card reader panel, or for staff who move around the site, passes are recorded without installing a separate device; mobile passes feed the same timesheet as the turnstiles. Because employees can see their own movements and leave balance, they no longer need to ask HR. For leave that requires a medical certificate or written request, the document is uploaded from the phone and the manager sees it on the approval screen. Expense requests, with a photo of the document, the company and the currency, and advance requests, with the amount and a description, go for approval without paper forms.
