Project Management

Architects use 16 broad general divisions to manage a construction project. Here they are:
  1. General conditions: all project support not involve direct construction
  2. Site work: clearing, hauling and excavation
  3. Concrete: pouring and foundation
  4. Masonry: installation of bricks, stones, stucco
  5. Metals: if metallic materials are used
  6. Wood and plastics: rough framing and finish carpentry for interior and exterior
  7. Thermal and moisture protection: heat, ventilation, moisture controlled
  8. Doors and windows: interior and exterior
  9. Finishes: sheetrock, trim, moulding, painting, ceiling covering, tile, flooring
  10. Specialities: bathroom accessories, attic ventilation
  11. Equipment: garagage door openers, kitchen appliances
  12. Furnishings: window treatments, cabinetry
  13. Special construction: shelter, theater, sauna
  14. Conveying systems: elevators, wheelchair lift
  15. Mechanical systems: plumbing, air-conditioning
  16. Electrical systems: lightings, receptacles, controls, phone, cable

These divisions help to break down the project by tasks and so make easy to manage. It can use also to create a budget by category for the entire project. You may not have to use all the 16 divisions in a given project.

Design Considerations
House specifications including all the instructions necessary to start building the house from floorplan to construction techniques are conveyed to the contractors via blueprints. Plans should include all the necessary details. The more details the less things are left to interpretation by the different sub-contractors. Design plans should include the following:
  1. Front elevation
  2. Left and right elevations
  3. Rear elevation
  4. Floorplan for all the floors
  5. Roofing plan
  6. Foundation plan
  7. Interior elevation
  8. Framing details
  9. Electrical layout
  10. Plumbing diagram
  11. Special instructions
  12. Wall wall cross section
  13. Set of specifications to include instructions for the subs
  14. General construction specifications and requirements
If you were to work with an architect, he/she and you will work together to arrive at the general conception of the finished house. An architect will first do a schematic design based on your discussions with him about the style, type and size of house you want. During the schematic design phase he will sketch the house profile and some components for you to review and make changes. He will also consider the lot size, topography, orientation, climate and configuration. Next, the architect will move to design development phase. You will need to come up with more details including finishes, exterior materials, roof style, electrical and other features. Cost estimate will evolve from this phase. If it is approved, the architect will move to create the construction documents to start building the house. The construction document will include detailed plans along with special instructions and specifications. In addition, an architect may for a fee manage the building project from bidding to the final construction.

The Construction Schedule
The construction schedule serves as an important tool in the hand of the owner/builder manager –It includes many fundamental variables that can assist in keeping the construction project moving along smoothly. It will alert the construction manager when the project is about to run into snags, and help make needed adjustments when unforeseen circumstances arise. In order to achieve all that the plan has to be well coordinated, regularly updated and communicated to all the parties involved. In order to be successful the plan must:

  • Outline the progress expected on a construction project in a timeline that is the most efficient and cost effective possible.
  • Give the project stakeholders a realistic timeline by which they can expect the project to be completed. It lays out the sequence of events and the process that will be followed by major contractors and subcontractors, making it easier for him to monitor.
  • Serve as a scheduling, coordination and feedback tool for the project manager, who can use it to schedule workers, time material deliveries and equipment rentals and monitor the progress in case of needed changes.
  • Serve a as daily, weekly and monthly benchmark of the actual progress of the project.
  • Serve as a base plan for any changes that might have to be made due to unforeseen circumstances, unexpected delays or owner changes and additions.
  • Use as a tool to document work completed as the involved parties sign off on agreed upon completion.
  • Serve as legal documentation of the actual history and events of the construction and can be useful in the event of litigation or conflict resolution.
  • Serve as a guide in future projects

Open Communication

Open communication between the parties involved is very important once construction begins. Everyone who is a part of the project team needs to be informed and keep up-to-date of the project schedule. Since open communication helps to keep a project running smoothly, it’s of great importance when unexpected complications arise.

Keeping the lines of communication open involves making regular updates on progress. Project progress must be tracked regularly. Any foreseable or possible delays need to be noted as soon as possible, as well as finished work flagged. In addition to daily updates, regular weekly meetings of the team leaders are vital as well. These meetings should include all the parties and stakeholders including the project manager, the owners, and major subcontractors. Update meetings can provide a look forward on the project’s progress and possible difficulties or gains. By slicing the schedule into smaller blocks, periodic meetings can help make the transition from the big picture to a more detailed look at the tasks needed in the upcoming week. If a delay has caused the loss of time, the team members can work on recovering the lost time. If there is a gain, such as moving ahead of schedule, the team can come up with way to make the best use of the gain. Having the ability to update and make changes as soon as new information is available help reduce delays and allow everyone to make the best use of their time. All this should contribute to a highly successful project delivery.
