You are the General Contractor and have been awarded a lump-sum contract to build Midland Medical Centre on behalf of your Client, YYZ Medical Holdings Inc.
You have learned that Toronto Water has subcontracted their service connection works to a company named SewMainCo Inc. As you know these service connections typically terminate at the property line. However, you as the GC contacted SewMainCo and asked them to submit a price to do the additional site servicing works on the private property of Midland Medical Centre, outside of the building but within the property liens. The submitted tender price and scope were suitable, and so you awarded the site servicing work on private property to SewMainCo.
Therefore, on this project, one trade (SewMain Co Inc.) will be completing the sewer and watermain work both on city property (in Midland Avenue), as well as on the private property of Midland Medical Centre.
The Client is concerned with safety during site servicing works, as well as proper methods used to tie into the existing site services on their property. Accordingly, they have asked you to submit a Construction Work Method Statement. (In real life, this would be created by the GC with a great deal of input by the Subcontractor, and sometimes created solely by the Sub).
In the period around 2-3 months prior to work starting on site, your project management team is working on scopes of work for tender and award of Subcontracts to your various Subcontractors. One of the first Subcontracts to be issued is the work package for Excavation & Backfilling, so you will complete this among the first of your SOWs.
During this time you are also planning your work by creating numerous staging plans, to figure out the sequence of the work, plan for site access & protection, and test the viability of different equipment to be used for the project.
Student teams may ask questions regarding the project to the Instructor using a standard RFI template. Both student RFIs and the Instructor’s RFI responses will be posted to Blackboard, and shared with all student teams in the class.
For each of the Parts A, B, and C below, refer to the supplementary instructions posted to Blackboard in the Group Project #1 folder for additional instructions and/or examples.
Create a Construction Work Method Statement with all of the following sub-sections to describe how you will safely complete the site servicing works for the project, focusing on the installation of the proposed storm sewer system only. BLDG 2204 Pg 3 of 4 Group Project #1
You must include the entire storm system from Midland Medical Centre to its connection in the existing storm sewers under Midland Avenue. Include both storm chambers in your Method Statement, including Control MH1 and the “Oil-Grit Separator”. However, you may omit the rest of the stormwater management system north of MH1 (including the MC3500 units stormwater chamber units).
You may also omit the method statements on the sanitary sewer and domestic water system. We will simplify this project to just include the storm system.
As resources you will use drawing SG-01, the materials from the in-lab activity, lecture slides, and lecture notes.
To reiterate, we will assume that one trade (SewMainCo) will install the entire storm sewer system, both on city property and on private property. So, when you refer to specific chamber sizes and depths, pipe lengths, diameters, slopes, etc., these should be the full pipe runs both on city and private property.
You will write a contract scope of work (SOW) statement for the Excavation & Backfilling work package. In the real-world construction industry, SOWs are written first at the tender stage and included with tender packages to bidders; once a Subcontract scope and price are agreed upon, the SOW is included in the Subcontract and defines the contract responsibilities that the Subcontractor must fulfill.
To create these SOWs, you will use content from the lectures, lecture notes, lab activities, and quizzes (with quiz feedback). There will also be real-industry SOW examples provided on Blackboard. The purpose of this is to integrate the content from all of the above learning activities, and practice writing real industry documents. You should NOT search for SOWs on the Internet and copy/paste or paraphrase the content. BLDG 2204 Pg 4 of 4 Group Project #1
Provide a Sequencing & Staging Plan using the provided 11×17 template for the Below-Grade Construction phase, focusing the site setup and sequence of the concrete works. Submit a document with all assumptions & calculations you made in creating the staging & sequencing plan, including work rate calculations. Also provide a cut sheet for the boom truck or mobile crane and concrete pump you are planning on using to complete the concrete works.
The vast majority of content for this assignment should come from lectures, lecture notes, lab activities, quizzes and the associated quiz feedback, class discussions, and class RFIs.
Any material taken from outside these course materials must be correctly cited in APA format, both within the body of your paragraphs or bullet points, and also included in a separate references page.
PART A IN DEPTH
BLDG 2204 – Commercial Construction Technology
Group Project # 1 – Part A
Supplemental Instructions – Construction Work Method Statement
You must use the following format with all sub-sections (numbered i-v) and ensure you meet the requirements of each section as noted below.
BLDG 2204 Pg 2 of 2 Group Project #1 Supplementary Instructions – Part A
Be sure to use the site servicing drawings by Cole Engineering Group for Midland Medical Centre to refer to invert depths. Also be sure to use the maintenance hole shop drawing provided in lab (OPSD 701.010) to help calculate depths to the bottom of excavation.
See further readings and examples for Construction Work Method Statements in the subsequent pages. These are taken from Cooke & Williams’ (2009) book, Construction Planning, Programming, and Control.
Note that the format in Cooke & Williams’ examples differ slightly than the requirements above for Group Project #1. For your work sequence, you are using a numbered list, and you must ensure that for each numbered item you clearly describe the labour, materials, and equipment required to complete that step. Therefore, your Work Method Statement will be much more detailed than the examples provided.
Also beware that since this was taken from a British publication, there are several terms that you should convert to Canadian industry terms. For example, plant, banksman, tipper wagons, and groundworkers are British terms. Some of the correct Canadian terminology for labour and/or supervision might include: pipefitter, labourer (e.g. to control grades, do backfill & compaction, etc.), machine operator, surveyor, field engineer. RS Means CostWorks may be able to help you identify the names of the crew members for site servicing work.
For your section on Significant Hazards & Control Measures, make sure to use a table so that an appropriate risk control is noted for each risk.
PART B IN DEPTH
Group Project # 1 – Part B
Supplemental Instructions – Scope of Work (SOW) Statements
You will compose a scope of work (SOW) statement for Midland Medical Centre, for the Excavation & Backfilling work package. In the real-world construction industry, a SOW is written for each Subcontractor and the SOW becomes part of the Subcontract between General Contractor and the Subcontractor. Your SOW will define what and how the Excavation & Backfilling Subcontractor will complete all of their work related to the Midland project.
Scopes of Work (SOWs) outline a Subcontractor’s contract obligations.
It is recommended that you use a numbered list for each SOW section. It is recommended that you do NOT use a paragraph style.
You may begin each item in your numbered list with the phrase “Subcontractor shall…”.
A SOW statement should try to be both broad and specific. While this might seem paradoxical, we try to be broad/general so that we don’t accidentally forget an item. The phrase, “Including but not limited to” helps us be general while still listing some specific items. We also need to be specific about certain requirements, such as the amount of work space that the Excavation Sub will dig outside of the foundation walls, which facilitates formwork and waterproofing/drainage of the foundation walls.
If you were writing a SOW for the Site Servicing work package, your SOW might include the following items:
Items that are NOT included in an SOW Statement: BLDG 2204 Pg 2 of 3 Group Project #1 Supplementary Instructions – Part B
specific quantity. (e.g. specific amount of work space to excavate outside foundation wall).
BLDG 2204 Pg 3 of 3 Group Project #1 Supplementary Instructions – Part B
The Specifications can often be helpful when writing an SOW. Recall that the Specs are another contract document, composed by the consultants (Architect, Mech. Eng., etc.). The SOW will reference relevant sub-sections from the Specs, which will contractually include these sections as part of the Subcontract. Therefore, the Specs should not be repeated in your SOW, however the Architect discusses points in the Specs that may frame your thinking on the SOW, or help you remember items you may have forgotten to comment on.
On the Blackboard site, find attached two real SOW examples for the Masonry and
Carpentry work packages. These SOWs are from real GTA high-rise condo projects by Menkes Developments, and were provided as a courtesy to George Brown College for educational purposes.
You may adopt a similar format and approach as the Menkes examples, except you are writing an SOW specific to the Midland project and specific to Excavation & Backfilling.
The section called “GENERAL NOTES” with Notes 1 to 6 is a general section that Menkes includes with all SOWs. You do not need to include this section with your SOW; include only the specific section pertaining to Excavation & Backfilling. The General Notes section has been provided to you reference so you can see what real industry SOWs look like.

PART C IN DEPTH
Group Project # 1 – Part C
Supplemental Instructions – Sequencing & Staging Plan
Assume that bulk excavation is fully complete except for your excavation access ramp which will remain in place throughout the concrete works. The access ramp has been used during bulk excavation to drive triaxle trucks down into the excavation to remove soil. During the concrete works stage, you will use this access ramp to drive equipment into the excavation, which may include concrete trucks and/or a boom truck. Therefore on your staging plans you will draw the excavation ramp in an appropriate location that provides access off Midland Avenue, and which is in the best strategic place for other work occurring around this stage.
You will assume use of a boom truck (in the excavation) or mobile crane (outside the excavation) to assist your formwork crew in hoisting and moving formwork for foundation walls and column forms. A boom truck would be able to drive up and down the ramp to get closer to formwork elements which need to be moved around.
Assume you have three formwork crews – one working on strip footings, one on pad footings & piers, and a third crew on foundation walls. First figure out your production cycle for each crew working on these different structural elements (e.g. linear metres or square metres of footing or foundation wall) – this can come from lecture/lecture notes as well as RS Means CostWorks.
The work will require a boom truck or mobile crane that has enough reach to strip the foundation wall formwork and move the forms down to the next section of foundation wall based on this. You may assume that a single wall form (e.g. Aluma Gang Form) weighs 1,200 kg per 12m x 3.6m section. To pour concrete, you may assume use of the same boom truck or mobile crane, using a 1.0 m3 concrete bucket, for which you can calculate the mass.
