I've already discussed in advance the 2 most popular informal type of setup in construction ("Pakyawan" or "Arawan"), As I've said, as a professional, I wouldn't recommend any of the 2 setup.
Here are my reasons;
1. You need to be more hands-on. You are the one taking care of everything your workers need. It consumes most of your time. And if you don't have any experience in job site construction, you may be abused by your workers. You will be also handling all the paper works, leg works, permits and other documents pertaining to the project.
2. You cannot guarantee that the foreman or lead man can fully read and understand the plans, specifications and other documents. Some skilled workers are able to read the plans through experience, but would not probably understand everything in it specially technical engineering annotations. This might then pose a big risk on the structural safety of the building. But just to be fair, I've met some foreman that can read plans very well. Lucky for you if you found one like him.
3. Usually, there is no scientific justification in quantifying materials for ordering. When you ask your foreman about the materials they need, he will most likely just make a wild guess of how many of these... and how many of that...etc. which may end up either too much ordered materials which leads to possible wastage, or short in quantity making you pay more on delivery charges for ordering again.
4. The workers probably has no equipment, power tools and warehousing schemes. Your best option for the equipment is to rent and you might also need to buy some power tools. Some important equipment you might need are: 1-bagger mixer, Jackhammer, Concrete Vibrator, Water Pump, Welding Machine, Formworks and Scaffoldings, etc. Some of the power tools you will need are: Drills and Grinder/Edger, etc. Contractor's normally have all of these so you wouldn't need to worry about these including safekeeping and maintenance of these tools and equipment. You might also have material pilferage problems if you don't have proper warehousing. This is the most common problem with the 2 setup.
5. Legal issues. After your project is completed, you will now need to process your occupancy permit. This permit is also needed when you are applying for Power and Water connections. And because there are no construction professional that supervised the project, you might find it hard looking for an engineer to sign and seal the documents risking his license for a project that he doesn't know if built correctly as per design. You might again end up paying more than you should at this point.
6. No one is to be blamed or be held responsible if something terribly wrong happened in anytime during the construction period. Sure you can blame the foreman or the workers. But how can you hold them responsible? Jailing them will still leave you with the problems they've caused.
7. You will not have warranties and construction documentations after the project is completed. So if something wrong happened months after the construction is finished, there is no assurance that you can still find the foreman or the workers. You will again be paying them for the repair works that they will be doing. Also, troubleshooting(commonly on electrical failure) will be difficult since you don't have any reference documents or as-built plans.
CONSTRUCTION SETUPS INVOLVING PROFESSIONALS:
1. Direct Supervision - You hire a pro who directly supervises the workers, interpret the plans and make the estimates and ordering of materials. You pay either fixed monthly supervision fee or Cost-plus (monthly fee plus certain percent on the total actual expenses)
2. Direct to Contractor - You engage into a contract with a licensed contractor or construction firm. Some contractors with in-house designer/architect even offer free design and preparation of all needed plans and other contract documents.
3. Contractor through the Architect - You probably hired an Architect to prepare the plans. The architect, then invited contractors to bid for the project. And after bid evaluation, awarded the contract to the best bidder. (note: lowest bid is not always the best bid)
4. Managed Construction - You hire a Construction Manager. The CM then, hires a Contractor or several sub-contractors. CM manages the project and deals with the contractors on your behalf.
5. Contractor with Construction Manager - Same as no. 3 but with the addition of the Construction Manager directly hired by you.
For the next articles, I will be discussing each setup in details. I will point out advantages and disadvantages so you can have better idea on which setup will suit your requirements.

Construction Professionals
In my previous post "An Overview", my aim is for non-technical people to understand the roles of individuals in construction. But the question that follows is "Who's who?"
Note that this article will only focus on Construction in general.
FIELDS IN THE BUILDING INDUSTRY
1. Design - Professionals in this field are the ones conceptualizing and preparing the plans. Design is composed of Architectural, Structural, Electrical, Plumbing, Mechanical, and Specialized Allied (Interior, Acoustics, Lighting, etc.)
An Architectural design firm is usually headed by the principal architect. The firm is composed of architects, engineers, draftsmen(now CAD operators and 3D Renderers), Architectural design firms usually has consultants. They are the designers of the other trades mentioned above. They are not directly part of the firm but merely Partners in the business. A firm may actually have several consultants on each field.
Professionals of each trade:
Architectural - Architect, Interior Designer, Landscape Architect
Structural - Civil Engineer, Structural Engineer
Electrical - Registered Electrical Engineer, Professional Electrical Engineer, Registered Master Electrician
Plumbing - Sanitary Engineer, Registered Master Plumber
Mechanical - Mechanical Engineer, HVAC Engineer
Specialized Allied - Interior Designer, Interior Decorator, Acoustic Engineer, etc.
2. Contractor - Mostly composed of Engineers but there are some architects on board also. The contractor is the one in the site doing the construction works. Contractor or constructor has classes. This gauges their capability to handle size and complexity of a project. Contractors of multi-storey buildings should be a Tripple-A General Contractor. For residential projects, even class C or D are qualified depending on their performance.
Sub-contractors are usually hired by the General Contractor for a specific work in the construction. This can be Electrical works or Plumbing works, etc. Subcontractors are also considered as standalone contractors. They are only called sub-contractors if they are under the General contractor and does not have direct contract with the client.
3. Project/Construction Management - The Construction Manager is considered as the OWNER's representative, This can also be composed of a team of professionals depending on the scale and complexity of a project. In most residential and small commercial projects, there is usually one full-time construction manager but he is assisted by other trade consultants as needed. They are the ones managing the project, setting and monitoring of the schedule, checking of the materials and contractor's workmanship quality, review of the plans, contracts and other documents and coordinates with the Designer as necessary, making sure also that the plans are strictly implemented. They are also the ones assisting the OWNER of his responsibilities as well. As I've mentioned before, his main duty is to protect the OWNER's interest. He makes sure that the Contractor is doing his job faithfully and evaluates the accomplishments for payment. He fills up the owner's lack of technical knowledge to avoid being abused by the contractor. A construction manager can be an architect or engineer with years of experience in the industry.
4. Product Development and Sales - Some engineers chose the path of specializing in a specific construction material. Instead of involving directly in construction, they develop materials and services for use in buildings.
5. Government Service - Engineers, architects working in DPWH and other related government institution. Professionals in the office of the Building official and City Engineer and City planning and development.
6. Maintenance and Administrative - Often times, as a new building is completed, the OWNER absorbs one of the Construction Managers to be his Building Administrator. This is to take advantage of his knowledge on the construction history of the building. There are also new firms today that offer maintenance works only.
Construction is actually broader. But I believe the above explains the basics.
The question next is who to contact first if you want to build your house? I will be discussing this later. It is important that the CLIENT first understand the different construction setup. Please read my next post regarding this.
