PV Project Report: Nacita C (24MW)

Project Overview

Nacita C was a utility-scale PV project where our team supported the execution of solar installation works under challenging summer site conditions. The project was carried out during August, when high temperatures required a specific working schedule to protect the team and maintain safe productivity.

Due to the heat, working hours were organized from 05:00 until 12:00. This allowed the team to complete the most demanding site activities during the cooler part of the day while reducing the risk of heat stress.

The project also became more technically demanding than initially expected. At the beginning, the expected pre-drilling requirement was approximately 5%. During execution, the site conditions proved more difficult, and the actual pre-drilling requirement increased to approximately 20%.

As a PV mechanical installation partner, our role was to adapt quickly to the real site conditions, organize machinery efficiently, and maintain progress despite the increased ground preparation requirements.

Scope of Work

Our work on the Nacita C project focused on supporting the installation process with the necessary machinery, manpower, and site coordination required for utility-scale PV execution.

The project involved:

• PV mechanical installation support

• Pre-drilling works

• Ramming works

• Material handling

• Machinery coordination

• Site logistics

• Adaptation to difficult ground conditions

• Execution planning during limited working hours

The combination of high summer temperatures and increased pre-drilling requirements made planning especially important. Every working hour had to be used efficiently because the daily work window was limited to the early part of the day.

Main Site Challenges

Working During August Heat

One of the main challenges on Nacita C was the summer working environment. The project was executed during August, when high temperatures can create serious risks for construction teams working outdoors.

To manage this, the working schedule was adjusted to 05:00–12:00. This helped reduce exposure to peak daytime heat and allowed the team to continue working in safer and more productive conditions.

For EPC partners, this type of flexibility is important. Utility-scale solar projects often face weather-related constraints, and the execution team must be able to adapt without losing control of the schedule.

Increased Pre-Drilling Requirement

The second major challenge was the change in actual ground conditions compared to the initial expectation.

At the start of the project, approximately 5% pre-drilling was expected. However, during execution, the ground conditions proved more difficult, and the actual requirement increased to approximately 20% pre-drilling.

This created additional work and required careful coordination between the pre-drilling and ramming teams. If not managed properly, increased pre-drilling can slow down the full mechanical installation sequence.

Our team adapted the work organization and machinery planning to manage the increased pre-drilling requirement while maintaining progress on site.

Machinery and Site Resources

The project was supported with a strong machinery setup suitable for utility-scale PV construction.

Machinery used on site included:

• 2 excavators

• 2 telehandlers

• 1 pre-drill machine

• 2 ramming machines

• 2 bobcats

This combination allowed the team to manage several key activities, including material movement, ground preparation, pre-drilling, ramming, and mechanical installation support.

The availability of dedicated pre-drilling and ramming equipment was especially important because the actual ground conditions required more drilling than originally expected.

Execution Approach

The main execution priority on Nacita C was to maintain safe and efficient progress despite limited working hours and increased pre-drilling.

The team focused on:

• Starting work early to avoid peak heat

• Coordinating machinery before the daily work window began

• Prioritizing critical activities during cooler hours

• Managing the sequence between pre-drilling and ramming

• Keeping material movement organized

• Reducing idle time between machines and teams

This approach helped keep the site moving even though the project conditions were more demanding than initially planned.

Health and Safety

No incidents were recorded on the Nacita C project.

This is an important result because the project was executed during August heat and involved several types of heavy machinery, including excavators, telehandlers, ramming machines, a pre-drill machine, and bobcats.

The adjusted working schedule from 05:00 to 12:00 helped reduce heat-related risks and supported safer working conditions for the team.

Final Result

Nacita C demonstrated our ability to work as a reliable PV mechanical installation partner under demanding site conditions.

The project required adaptation to high summer temperatures, limited daily working hours, and a pre-drilling requirement that increased from the initially expected 5% to approximately 20%.

Despite these challenges, the work was completed with no recorded incidents, supported by proper machinery planning, early working hours, and practical site coordination.

For EPC companies looking for a dependable solar installation subcontractor, Nacita C shows the importance of having an execution partner who can adapt quickly when real site conditions differ from the initial plan.

Summary

The Nacita C project highlights our ability to manage utility-scale PV execution in challenging site conditions.

Key points:

• Utility-scale PV installation project

• Work executed during August heat

• Working hours adjusted to 05:00–12:00

• Expected pre-drilling increased from 5% to approximately 20%

• 2 excavators, 2 telehandlers, 1 pre-drill machine, 2 ramming machines, and 2 bobcats used on site

• No incidents recorded

• Execution adapted to limited working hours and more difficult ground conditions

Nacita C is a practical example of how an experienced PV execution team can maintain safe and organized site progress when weather, ground conditions, and construction realities create additional pressure.
