Routine inspection is critical in each and every part of your construction project. Inspections guarantee that works within a project go forward as planned and are according to requirements, standards and regulations. Running a construction site requires the coordination of people, materials and equipment hence, construction inspections are executed for a great number of purposes in every construction phase and throughout the entire project duration to ensure that things are progressing smoothly.

Construction inspections are usually carried out as a contractual responsibility performed by the contractors to provide the client or a third party an independent view of the construction works and their progress. The usual construction inspections include the following activities:

• Inspection of the construction process to make sure that all materials and procedures comply with the plan and specifications
• Inspection and documentation of all contractor activities
• Reporting of daily on-site inspections
• Detailed inspections of the quality of installations if they comply to standards and specifications
• Scrutinising drawings and specifications and discussing deviations and non-conformities
• Keeping and maintaining inspection checklists and records in a complete, accurate, and orderly manner
• Participation in project meetings
• Monitoring the contractor’s schedule
• Inspections of paints and coatings
• Field testing and materials sampling of soils, concrete and asphalt, etc.
• Review and completion of change order/s
• Monitoring and documenting materials delivered and used in the construction works
• Performing semi-final and final inspections upon building completion
• Preparation of punch list/s and monitoring of completion works
• Handover inspection for smooth project close-out

Progress

Most inspections are usually conducted but not limited during the construction phase. But before you can inspect and start reporting on a project’s progress, specific inspections are carried out as part of the general contract administration process. These inspections may be part of the contract review and contract signing, pre-contract meetings and client onboarding.

Construction site inspectors may either be the project manager, a member of the contractors’ existing team or an entirely different consultant. Depending on the size of the project, site inspection may have to be carried out by a team with specific inspectors per different department of the project. Design consultants also play a role in periodic inspections. For specific aspects of a project, specialist inspectors may be required to perform inspections on environmental policy, waste management on site, accessibility, etc.

Since site inspectors furnish the contract manager or project manager with independent evaluation of construction works and their progress, site inspectors usually keep daily construction logs or a site diary, front construction progress meetings, and create and submit regular reports.

Quality

Quality control (QC) inspections involve those that ensure that the construction works comply with requirements. For construction quality, there are technical specifications that describe what controls must be carried out to guarantee that construction works are carried out satisfactorily.

These controls are not only for the products and materials, but also include the execution and completion of the construction works. Inspections are a way to control the quality of a finished construction work. The desired outcome is to refine the product or work before being presented to the client such that those that do not comply with requirements are fixed.

Your goal is to reduce the costs of poor quality and that the deliverable project complies with all of the client’s requirements whether you’re implementing internal or external controls, or even both.

The international standards applied to construction is the which includes technical guides, reports and specifications related to the efficiency of a construction organisation’s quality management system. Basically, the principles that determine the quality management in construction standards are: scope of the construction project, the budget of the project and the schedule for completion. In the EU, the that is being primarily followed for the standardisation of construction works, processes and systems. Specific inspections may be formulated to cater and qualify compliance to requirements associated with this directive.

Construction inspections related to quality may include checks for materials, work units, processes and services designed and planned by the construction company in order to comply with the contract’s quality requirements. For preventative strategies, an inspection scheme is also aligned with the quality plan for the construction works requiring guarantee in construction quality. Inspections may also be carried out around documentation, work instructions, action plans, etc. for the execution and control of construction processes. These quality control inspections may also be replaced with certifications by third parties.

Health and safety

Construction inspections are also important to make sure that health and safety, the Construction (Design and Management) (in the UK), and the European Agency for Safety and Health at Work regulations and standards are being complied with and followed.

These inspections can be internally conducted by the contractor, or externally by the regulating body, or by third party audits. The needed to be conducted in the construction site is a specific list and should be conducted exhaustively as per required:

• Prevention of falls and personal fall protection systems
• Work at height
• Work platforms such as scaffold and mobile platforms
• Ladders and stepladders
• Personal protection equipment (PPE), including head protection
• Plant, vehicles and other equipment
• Storage
• Electrical systems
• Asbestos risk
• Provision of welfare facilities such as toilets and handwashing facilities
• Site conditions and order
• Avoidance of obstructions
• Management of respiratory risks
• Structural stability
• Prevention of unauthorised access to the site

The timing of inspections should be scheduled as to frequency and accompanied with correct reports and actionable items.

Building control

In Europe, it is the Consortium of European Building Control that and includes professional organisations, government bodies or a comparable agency.

These building control inspections are usually executed by a building control local authority or by an approved third-party inspector. Building control inspections are generally required in the following :

• Commencement
• Excavation (before excavations are filled)
• Foundations (before they are covered up)
• Laying of damp proof courses
• New drains installation (before covering up)
• Construction of the primary structure
• Installation of insulation
• Roof construction
• Completion

Other Inspections

There are other construction inspections not included in the categories above, which include:

• Planning inspections to substantiate compliance with planning permissions, conditions and obligations
• Inspections for release of funding by applicable agencies
• Insurance inspections
• Routine inspections of street works by highway authorities for road and sewer construction types
• Environmental inspections related to pollution (noise, water, smoke, etc.) and installations like kitchens and drains
• Fire safety inspection for fire escapes, protection systems, hazards and storage of certain materials
• Factory inspections
• Aracheological inspection of excavations

Some construction inspection guidelines

As mentioned, the main quality measures of a construction project are the project scope, the budget and the time for completion. Always go back to these three main points when you’re planning an inspection.

Project scope

The defined scope of the construction project should be leading the inspection processes at all times wherein the client’s needs are the main focus of the scope. All construction inspection checklists and all construction reports must always have the client’s details with thorough notes of communication history between the client and your construction staff.

Every little thing adjusted or installed must be authorised by your client. Communication with the client is the top priority of any of your construction project checklists. Use construction inspections to make sure everything is going according to the project scope.

Budget

All of your construction inspection checklists that deal with money must always reference the project budget. Completing a project within budget is another priority as a contractor or project manager, which greatly reflects the quality of your work.

Make sure to have inspections that would ensure the coordination of your suppliers, the purchasing of materials, labor activities and payouts, etc. Make use of your construction inspections wisely to monitor that every spending falls within the budget as you progress from one phase to the next even until completion.

Schedule

Your construction project schedule directly affects your client’s budget and needs, which can turn a satisfied client into a dissatisfied one bringing some costly litigation to the table. Utilise construction inspections to monitor your project schedule on a daily, weekly and monthly basis.

Always update all relevant stakeholders of any kind of delay including their details. Delays in construction can cost a lot; always keep to the clearly defined project schedule at the start of all construction activities.

Construction errors and change orders

Human error and change orders are inevitable in construction projects. The importance of construction inspection lies in a good inspection system that deals with errors and necessary changes. Having a good inspection system centred around the connectedness of your project teams will help you with the success of your construction project and its on-time delivery.
