Project Construction Methodology

Construction methodology or project execution methodology refers to the planned method of construction, taking into account all contractual and legal requirements, construction constraints, risks, and opportunities.

Project Methodology includes the temporary and permanent works and the services required to complete the construction works.

Below is given a detailed methodology for construction of a civil project, which can be used for planning a good project and to show the clients and consultants that a civil main contracting company is able to manage a project.

This approach can be customized as per site requirements and can help planning & operation departments to prepare a professional construction methodology.

IMPLEMENTATION STRATEGY PLANS & PROCEDURAL APPROACH

This project implementation strategy also called construction methodology provides general information of the methods procedures and sequencing to be used fur the project. Where specific areas of work are of a difficult nature, safety concern or there is a specific requirement a detailed method statement will be prepared in the future

In developing the planning the site location should be considered nod it will be necessary to mobilize and establish at the site various temporary facilities and equipment prior to commencing the works.

It is also necessary to establish and hare certain staff at the site for the works. this will be at an agreed location with the client.

Initial planning, preparation of shop drawings, detailing material procurement and arrangement of sub contractors will be carried out from the head office.

PROJECT CONTROL SYSTEM

The planning and documentation requirements listed here are considered adequate control for the works and no further criteria for the detailed plans or procedures are deemed necessary.

Upon the award of the contract a detailed project quality and management plan would be prepared.download editable project documents

This will address in detail the requirements of the contract and specifically the procedures and plans outlined in the various annexure for schedule project control services.

ORGANISATION CHART

The company organization chart of the project shows both the head office personnel and the sue personnel. Initially all administrative and technical personnel would be based at company head office. However when the project is fully mobilized the staff would be located at site.

CONSTRUCTION METHODOLOGY PROJECT PLANNING

The construction methodology or execution planning services will be provided in accordance with contract requirements. The level I works master schedule will be based on the tender scheme program and will be submitted initially after the contract award.

Following the review and approval of the level I program the more detailed levels of programs will be prepared.

Project control is required for the following documentation.

a) Shop drawing preparation.

b) Material procurement.

c) Arranging subcontractors.

d) Material delivery

The program dates for these items will he derived from the overall project schedule.

Exporting these items from the primavera database to a spreadsheet will be done to implement this.

This will allow the preparation of customizable report showing the status on each of these activities.

Initially all of the planning activities will be carried out in the company head office using a senior planner.

The work carried out on a project will comprise of monitoring progress, updating the schedule and providing short term look ahead programs.

Actual progress of the works is continuously monitored and compared with the schedule.

Variances are defined and assessed In case of any delay, a recovery plan is prepared along With costs and resources impact.

CONTRACT & SHOP DRAWINGS

On the award of the contract the contract-drawing list as per the front index sheet will be prepared as a spreadsheet.

This will be used as the basis for the drawing register for the project.

 Additional columns or fields will be added to indicate when the drawing is distributed to a particular party or subcontractor.

In the event that any of the contract drawings are modified and reissued a new entry will be added to the list. The spreadsheet will contain an additional field for the revision number and date.

At the start of the contract a thorough review would be carried out of the construction methods.

Based on the complexity of the particular work and the level of detail in the contract drawings a master list of shop drawings envisaged will be prepared.

Consultation will be held with subcontractors to verify the draft drawing list shop for their work.

The master list of shop drawings will include the following information on a spreadsheet

a) Drawing reference.

b) Drawing title,

c) Discipline

d) Drawing originator

e) Preparation date.

f) Issue for approval date.

SUBCONTRACTORS SELECTION METHODOLOGY

At the tender stage a preliminary list of subcontractors will be prepared and used for Inquiries.

However upon award of the contract a thorough review would be carried out of the list of subcontractors At the start of the project a list of all the subcontracts will be prepared.

The scope of work for the subcontractors will be precisely defined and identified by using the bill of quantities stern numbers.

The bill of quantities will be prepared on a spreadsheet and this will allow specific activities / work relevant to one subcontract to be edited out.

This will provide financial control reporting on information obtained from the spreadsheet.

Additional columns will be introduced in the spreadsheet to identify which subcontract the work is allocated to.

In the case of one bill item being split between the main contractor and different subcontractors the bill item will be split.

The drawings relevant to each subcontract will be identified.

A standard form of the contract will be prepared that is specific to the project. This will reflect the contract terms and conditions of the main contract with the client.

The standard form of subcontract will identify the facilities, services, temporary works, plant and equipment to be provided by the main contractor and by the subcontractor.

CONSTRUCTION PROJECT PROCUREMENT STRATEGY 

This section of the project construction methodology plan covers the procurement of the permanent works equipment, materials and services which can either be arranged as

  • A material supply contract from a local company
  • A material supply contract from an overseas company
  • As sub contracted work where the sub contractor provides plant, equipment, materials and labor for the installation or construction.
  • A material supply, which is under prime cost and will be decided during the project.

On the award of the contract a comprehensive list of all the permanent works materials will be prepared along with the work elements to be subcontracted.

Based on this list inquiries will be sent out to potential suppliers or subcontractors. Inquiries will include relevant bill of quantities sections, contract drawings, specifications sections and program dates. Suppliers / subcontractors will be given a set time period to respond.

This period will depend on the complexity of the supply or subcontractors works. The returned material or subcontract offers will be reviewed for their compliance with the contract documents for quality and ability to meet program.

The cost and commercial terms of each offer will be reviewed based on the best quality and ability to meet program and cost. A potential material supplier or subcontractor will be identified and submitted to the client for approval. After approval of the material supplier or subcontractor an award will be made using the standard format terms and condition for the supply. After the award the precise programme dates will be discussed in detail with the supplier or subcontractor.

The subcontractor will prepare shop drawings relevant to his scope of work. Once an order is placed, regular follow-ups with the supplier/ subcontractor are carried out to ensure compliance with the delivery schedule.

MATERIAL QUALITY CONTROL METHODOLOGY

In order to establish the required standard of supplied materials samples of the material will be supplied where appropriate. These will be kept on site and referenced as the submission sample.

These will be available for inspection by the client and the consultant and can be used in comparison with the supplied materials. On receipt of the product. QC personnel inspect the items to ensure compliance with norms and approvals.

This work shall be carried out in advance of the program dates for the main work.

COMMUNICATIONS & INFORMATION TECHNOLOGY
